Devices Supported: MCP1631HV, PIC16F883

Summary Description:

The MCP1631HV Multi-Chemistry reference design board is used to charge one to five NiMH or NiCd batteries, charge one or two cell Li-Ion batteries, or drive one or two 1W LEDs. The board uses the MCP1631HV high speed analog PWM and PIC16F883 to generate the charge algorithm for NiMH, NiCd or Li-Ion batteries. The MCP1631HV Multi-Chemistry Battery Charger is used to evaluate Microchip’s MCP1631HV in a SEPIC power converter application.
