REFERENCE DESIGN?
WHAT THE MCP1631 MULTI-CHEMISTRY BATTERY CHARGER
REFERENCE DESIGN KIT INCLUDES
The MCP1631 Multi-Chemistry Battery Charger Reference Design is a complete
stand-alone constant current battery charger for NiMH, NiCd or Li-Ion battery packs.
When charging NiMH or NiCd batteries the reference design is capable of charging
one, two, three or four batteries connected in series. If Li-Ion chemistry is selected, the
board is capable of charging one or two series batteries. This board utilizes Microchip’s
MCP1631HV (high-speed PIC® MCU PWM TSSOP-20). The input voltage range for
the demo board is 5.3V to 16V.
TABLE 1-1:
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 10 kΩ thermistor. A programming header is available for
updating the firmware contained in the PIC16F883.
This MCP1631 Multi-Chemistry Battery Charger Reference Design kit includes:
• The MCP1631 Multi-Chemistry Battery Charger Reference Design Board,
• Analog and Interface Products Demonstration Boards CD-ROM (DS21912)
