MCP1631HV Multi-Chemistry Battery Charger Reference Design
1.2
WHAT IS THE MCP1631HV MULTI-CHEMISTRY BATTERY CHARGER
REFERENCE DESIGN?
The MCP1631HV Multi-Chemistry Battery Charger is a complete stand-alone battery
charger for NiMH, NiCd or Li-Ion battery packs. The board may also be used to drive
LED devices using constant current mode. When charging NiMH or NiCd batteries the
reference design is capable of charging one to five batteries connected in series. If
Li-Ion chemistry is selected, the board is capable of charging one or two series
batteries. When the LED driver is selected, the board is capable of driving one to two
1W LEDs. This board utilizes Microchip’s MCP1631HV (high-speed PWM and
PIC16F883 MCU). The input voltage range for the demo board is 5.3V to 16V.
The board is capable of both boosting and bucking the input voltage in order to obtain
the desired output voltage because a SEPIC converter topology is used. The overvolt-
age limit for the board is set to 9V. The powertrain components may be changed to
allow for higher output voltages and power.

An input terminal block is provided to apply the input voltage to the charger. An output
header is also provided as a means to connect the external battery pack or simulated
battery load and external 10K thermistor. A programming header is available for
updating the firmware contained in the PIC16F883.
