Typical Application

Description:

The MCP73831/2 devices are highly advanced linear

charge management controllers for use in space-lim-

ited, cost-sensitive applications. The MCP73831/2 are

available in an 8-Lead, 2 mm x 3 mm DFN package or

a 5-Lead, SOT23 package. Along with their small

physical size, the low number of external components

required make the MCP73831/2 ideally suited for por-

table applications. For applications charging from a

USB port, the MCP73831/2 adhere to all the

specifications governing the USB power bus.

The MCP73831/2 employ 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 accommodate new, emerg-

ing battery charging requirements. The constant cur-

rent value is set with one external resistor. The

MCP73831/2 devices limit 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 termi-

nation 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 dis-

abled. Refer to Section 1.0 “Electrical Characteris-

tics”

for

available

options

and

the

“Product

Identification System” for standard options.

The MCP73831/2 devices are fully specified over the

ambient temperature range of -40°C to +85°C.
