INTRODUCTION
The MCP1630 Low-Cost NiMH Battery Charger Reference Design is used to charge
three series cell NiMH or NiCd batteries. The board uses the MCP1630 high-speed
analog PWM and PIC12F683 to generate the charge algorithm for NiMH or NiCd
batteries.
The MCP1630 Low-Cost NiMH Battery Charger Reference Design is used to evaluate
Microchip’s MCP1630 in a SEPIC power converter application. As provided, the
MCP1630 Low-Cost NiMH Battery Charger Reference Design is capable of charging a
three series cell NiMH battery pack from an input voltage of 6V to 14V. The MCP1630
Low-Cost NiMH Battery Charger Reference Design provides a constant current charge
with preconditioning, cell temperature monitoring and battery pack fault monitoring.
Also, the charger provides a status or fault indication. The MCP1630 Low-Cost NiMH
Battery Charger Reference Design automatically detects the insertion or removal of a
battery pack.
