MCP1630RD-LIC2

The MCP1630RD-LIC2 is a MCP1630 low cost Li-Ion battery charger a complete stand alone constant current, constant voltage battery charger for single cell Li-Ion battery packs. Different battery chemistries (i.e. three NiMh or NiCd batteries connected in series) can be charged with minor modifications to the firmware. Multiple series cell Li-Ion battery packs can be charged with minor modifications to the hardware. This board utilises MCP1630 (high speed PIC MCU PWM MSOP8), MCP6292 (dUAL op-amp MSOP8), and PIC12F683 (Flash MCU SOIC8). The input voltage range for the demo board is 6V to 18V. The output is capable of charging at a fast charge rate of 2A constant current. 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. A programming header is available for updating the firmware contained in the PIC12F683.

• Programmed parameters modified in firmware
• Overvoltage protection (battery removed)
• Over charge protection to prevent the battery from becoming dangerously overcharged
• Over current protection in the event of a shorted battery
• Over temperature protection to prevent the battery from reaching too high a temp during charge
• Fast charge termination if the battery temperature is outside a preset window
• The MCP1630 low cost Li-Ion battery charger has the flexibility to optimize the charging algorithm
• 2A constant current fast charge
• 4.2V constant voltage charge
• 200mA preconditioning charge current
