INTRODUCTION
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. As provided, the MCP1631HV
Multi-Chemistry Battery Charger is user programmable using on board push buttons.
The board can charge NiMH, NiCd or Li-Ion batteries. The MCP1631HV Multi-Chem-
istry Battery Charger provides a constant current charge (Ni-based chemistry) and con-
stant current / constant voltage (Li-Ion) with preconditioning, cell temperature
monitoring (Ni-based) and battery pack fault monitoring. Also, the charger provides a
status or fault indication. The MCP1631HV Multi-Chemistry Battery Charger automati-
cally detects the insertion or removal of a battery pack.
