Controller with Input Overvoltage Protection

Description

The MCP73113/4 are highly integrated Li-Ion battery

charge management controllers for use in space-

limited

MCP73113/4

algorithms for Li-Ion/Li-Polymer batteries to achieve

optimal capacity and safety in the shortest charging

time possible. Along with their small physical size, the

low number of external components make the

MCP73113/4 ideally suitable for portable applications.

The absolute maximum voltage, up to 18V, allows the

use of MCP73113/4 in harsh environments, such as

low cost wall wart or voltage spikes from plug/unplug.

The

current/constant voltage charge algorithm. The various

charging voltage regulations provide design engineers

flexibility to use in different applications. The fast

charge, constant current value is set with one external

resistor from 130 mA to 1100 mA. The MCP73113/4

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.

The PROG pin of the MCP73113/4 also serves as

enable pin. When high impedance is applied, the

MCP73113/4 will be in standby mode.

The MCP73113/4 devices are fully specified over the

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

are available in a 10 lead, DFN package.
