The MCP1630DM-NMC1 is a MCP1630 NiMH battery charger demo board, The MCP1630 high speed PWM which is interfaced to the PIC16LF818 to develop a complete NiMH battery charger with fuel gauge capability. The MCP1630 is used to regulate the battery charge current and protect the SEPIC power train against an open circuit (removed battery) or a shorted battery. The high speed 12ns current sense to output capability of the MCP1630 is used to switch the SEPIC converter at 1MHz, minimizing external inductor and capacitor cost, while the PIC16LF818 performs the complex NiMH battery charger timing functions. Both the MCP1630 and PICLF818 protect the battery and circuit in the event of a fault. The input voltage range for the demo board is 8V to 15V. The output is capable of charging four NiMH batteries with up to 1.6V per cell at a fast charge rate of 500mA contant current.
