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, 3 mm x 3 mm DFN package or a 10-Lead,

MSOP package. Along with its small physical size, the

low number of external components required makes

the

applications. 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 conditions. 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

Characteristics” for available options and the

“Product Indentification System” for standard

options.

The MCP73833/4 is fully specified over the ambient

temperature range of -40°C to +85°C.
