Application Information  
Explanation of Operation  
For both the open drain type (Fig.12) and the CMOS output type (Fig.13), the detection and release voltages are used as  
threshold voltages. When the voltage applied to the VDD pins reaches the appropriate threshold voltage, the VOUT terminal  
voltage switches from either “High” to “Low” or from “Low” to “High”. Please refer to the Timing Waveform and Electrical  
Characteristics for information on hysteresis.  
Because the BD48xxx series uses an open drain output type, it is necessary to connect a pull-up resistor to VDD or another  
power supply if needed [The output “High” voltage (VOUT) in this case becomes VDD or the voltage of the other power  
supply].

Timing Waveform  
Example: the following shows the relationship between the input voltages VDD and the output voltage VOUT when the  
input power supply voltage VDD swept up and down (the circuits are those in Fig.12 and 13).  
1
When the power supply is turned on, the output is unstable  
VDD  
from after over the operating limit voltage (VOPL) until tPHL.  
Therefore it is possible that the reset signal is not outputted when  
the rise time of VDD is faster than tPHL.  
VDET+ΔVDET

When VDD is greater than VOPL but less than the reset release

voltage (VDET + VDET), the output voltages will switch to Low.  
3
If VDD exceeds the reset release voltage (VDET + VDET), then  
VOUT  
VOUT switches from L to H.

supply is powered down or when there is a power supply  
fluctuation, VOUT switches to L (with a delay of tPHL).  
5
The potential difference between the detection voltage and the  
release voltage is known as the hysteresis width (VDET). The  
system is designed such that the output does not toggle with  
power supply fluctuations within this hysteresis width, preventing  
malfunctions due to noise.

3) Examples of the power supply with resistor dividers  
In applications wherein the power supply voltage of an IC comes from a resistor divider circuit, an in-rush current will flow  
into the circuit when the output level switches from “High” to “Low” or vice versa. In-rush current is a sudden surge of  
current that flows from the power supply (VDD) to ground (GND) as the output logic changes its state. This current flow  
may cause malfunction in the systems operation such as output oscillations, etc.

Fig.18  
When an in-rush current (I1) flows into the circuit (Refer to Fig. 18) at the time when output switches from “Low” to “High”,  
a voltage drop of I1×R2 (input resistor) will occur in the circuit causing the VDD supply voltage to decrease. When the  
VDD voltage drops below the detection voltage, the output will switch from “High” to “Low”. While the output voltage is at  
“Low” condition, in-rush current will stop flowing and the voltage drop will be reduced. As a result, the output voltage will  
switches again from “Low” to “High” which causes an in-rush current and a voltage drop. This operation repeats and will  
result to oscillation.

Operational Notes  
1) Absolute maximum ratings  
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit  
between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such  
as adding a fuse, in case the IC is operated over the absolute maximum ratings.  
2) Ground Voltage  
The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no  
pins are at a voltage below the ground pin at any time, even during transient condition.  
3) Recommended operating conditions  
These conditions represent a range within which the expected characteristics of the IC can be approximately obtained.  
The electrical characteristics are guaranteed under the conditions of each parameter.  
4) Bypass Capacitor for Noise Rejection  
To help reject noise, put a 1µF capacitor between VDD pin and GND and 1000pF capacitor between VOUT pin and GND.  
Be careful when using extremely big capacitor as transient response will be affected.  
5) Short between pins and mounting errors  
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong  
orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins.  
6) Operation under strong electromagnetic field  
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.  
7) The VDD line impedance might cause oscillation because of the detection current.  
8) A VDD to GND capacitor (as close connection as possible) should be used in high VDD line impedance condition.  
9) Lower than the mininum input voltage puts the VOUT in high impedance state, and it must be VDD in pull up (VDD)  
condition.  
10) External parameters  
The recommended parameter range for RL is 10kto 1M. There are many factors (board layout, etc) that can affect  
characteristics. Please verify and confirm using practical applications.  
11) Power on reset operation  
Please note that the power on reset output varies with the VDD rise time. Please verify the behavior in the actual  
operation.  
12) Testing on application boards  
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject  
the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should  
always be turned off completely before connecting or removing it from the test setup during the inspection process. To  
prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and  
storage.  
13) Rush current  
When power is first supplied to the IC, rush current may flow instantaneously. It is possible that the charge current to  
the parasitic capacitance of internal photo diode or the internal logic may be unstable. Therefore, give special  
consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of connections.  
14) This IC has extremely high impedance terminals. Small leak current due to the uncleanness of PCB surface might  
cause unexpected operations. Application values in these conditions should be selected carefully. If 10Mleakage is  
assumed between the CT terminal and the GND terminal, 1Mconnection between the CT terminal and the VDD  
terminal would be recommended. Also, if the leakage is assumed between the Vout terminal and the GND terminal, the  
pull up resistor should be less than 1/10 of the assumed leak resistance.

extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way  
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any  
special or extraordinary environments or conditions. If you intend to use our Products under any special or  
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of  
product performance, reliability, etc, prior to use, must be necessary:  
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents  
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust  
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,  
H2S, NH3, SO2, and NO2  
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves  
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items  
[f] Sealing or coating our Products with resin or other coating materials  
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of  
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning  
residue after soldering  
[h] Use of the Products in places subject to dew condensation  
4) The Products are not subject to radiation-proof design.  
5) Please verify and confirm characteristics of the final or mounted products in using the Products.  
6) In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse) is applied,  
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power  
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect  
product performance and reliability.  
7) De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual  
ambient temperature.  
8) Confirm that operation temperature is within the specified range described in the product specification.  
9) ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in  
this document.

Precaution for Mounting / Circuit board design  
1) When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product  
performance and reliability.  
2) In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the  
ROHM representative in advance.  
For details, please refer to ROHM Mounting specification  
Precautions Regarding Application Examples and External Circuits  
1) If change is made to the constant of an external circuit, please allow a sufficient margin considering variations of the  
characteristics of the Products and external components, including transient characteristics, as well as static  
characteristics.

Precaution for Electrostatic  
This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper  
caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be  
applied to Products. Please take special care under dry condition (e.g. Grounding of human body / equipment / solder iron,  
isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity control).  
Precaution for Storage / Transportation  
1) Product performance and soldered connections may deteriorate if the Products are stored in the places where:  
[a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2  
[b] the temperature or humidity exceeds those recommended by ROHM  
[c] the Products are exposed to direct sunshine or condensation  
[d] the Products are exposed to high Electrostatic  
2) Even under ROHM recommended storage condition, solderability of products out of recommended storage time period  
may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is  
exceeding the recommended storage time period.  
3) Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads  
may occur due to excessive stress applied when dropping of a carton.  
4) Use Products within the specified time after opening a humidity barrier bag. Baking is required before using Products of  
which storage time is exceeding the recommended storage time period.
