Product Features

    • Load sharing system power path management that support charging single cell Li-Ion battery and system load at the same time without affecting charging algorithm of Microchip’s stand-alone charge management controllers.
    • The system load is supported by Li-Ion battery when input power source is removed
    • Blue LED indicates charge status
    • Additional Red LED to indicate Power-Good (PG) and Green LED to indicate charge complete (Available from MCP73833)
    • Dip Switch to select programmable fast charge current between1000 mA (H) and 50 mA (L) for MCP73833 and 400 mA (H) and 25 mA (L) for MCP73832
    • Available THERM pin on the MCP73833 for temperature monitoring with a thermistor. It is disabled by default and can be enabled to use with NTC thermistor
