FUNCTION  
2-, 3-, or 4-Cell Secondary Protection  
Low Power Consumption ICC < 2 µA  
[VCELL(ALL) < V(PROTECT)  
Each cell in a multiple-cell pack is compared to an  
internal reference voltage. If one cell reaches an  
overvoltage condition, the protection sequence  
begins. The bq2941x device starts charging an  
external capacitor through the CD pin. When the CD  
pin voltage reaches 1.2 V, the OUT pin changes  
from a low level to a high level.

OVERVOLTAGE PROTECTION  
When one of the cell voltages exceeds V(PROTECT), an internal current source begins to charge the capacitor,  
C(DELAY), connected to the CD pin. If the voltage at the CD pin, VCD, reaches 1.2 V, the OUT pin is activated and  
transitions high. An externally connected NCH FET is activiated and blows the external fuse in the positive  
battery rail; see the functional block diagram.  
If all cell voltages fall below V(PROTECT) before the voltage at pin CD reaches 1.2 V, the delay time does not run  
out. An internal switch clamps the CD pin to GND and discharges the capacitor, C(DELAY), and secures the full  
delay time for the next occurring overvoltage event.  
Once the pin OUT is activated, it transitions back from high to low after all battery cells reach V(PROTECT)– Vhys.  
DELAY TIME CALCULATION  
The delay time is calculated as follows:

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2)  
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder  
temperature.
