Microchip MCP1631HV | Demoboard MCP1631RD-MCC2

Beschreibung

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-Chemistry Battery Charger provides a constant current charge (Ni-based chemistry) and constant 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 automatically detects the insertion or removal of a battery pack.
