MCP1631RD-MCC2(#1): 1 ~ 5s NiMH, 1 ~ 2s Li-Ion Charger


The MCP1631HV Multi-Chemistry Battery Charger is fully assembled and tested for charging one or two series Li-Ion Batteries, one to five series cell NiMH or NiCd batteries, or driving one to two 1 Watt LEDs. The charge termination for Li-Ion is based upon a percentage of fast charge current, the charge termination for NiMH is based on a negative voltage change versus time or positive temperature change versus time.

This board requires the use of an external voltage source to charge the series connected batteries with a range of +5.3V to +16V input. An external load and thermistor is also required to evaluate the charger reference design.
