Description
The MCP73833/4 is a highly advanced linear charge
management controller for use in space-limited, cost
sensitive applications. The MCP73833/4 is available in
a 10-Lead, 3mm x 3mm DFN package or a 10-Lead,
MSOP package. Along with its small physical size, the
low number of external components required makes
the MCP73833/4 ideally suited for portable applica-
tions. For applications charging from a USB port, the
MCP73833/4 can adhere to all the specifications
governing the USB power bus.
The MCP73833/4 employs a constant current/constant
voltage charge algorithm with selectable precondition-
ing and charge termination. The constant voltage
regulation is fixed with four available options: 4.20V,
4.35V, 4.40V, or 4.50V, to accomodate new, emerging
battery charging requirements. The constant current
value is set with one external resistor. The
MCP73833/4 limits the charge current based on die
temperature during high power or high ambient condi-
tions. This thermal regulation optimizes the charge
cycle time while maintaining device reliability.
Several options are available for the preconditioning
threshold, preconditioning current value, charge
termination value, and automatic recharge threshold.
The preconditioning value and charge termination
value are set as a ratio, or percentage, of the
programmed constant current value. Preconditioning
can be set
to 100%
