INTRODUCTION
The MCP1631HV Multi-Chemistry Battery Charger demonstrates Microchip’s
high-speed Pulse Width Modulator (PWM), MCP1631HV, used in a multi-chemistry
battery charger application. When used in conjunction with a microcontroller, the
MCP1631HV will control the power system duty cycle to provide output voltage or
current regulation. The PIC16F883 microcontroller can be used to regulate output
voltage or set current, switching frequency and maximum duty cycle. The MCP1631HV
generates the duty cycle and provides fast overcurrent protection based upon various
external inputs. External signals include the switching frequency oscillator, the
reference voltage, the feedback voltage and the current sense. The output signal is a
square-wave pulse. The power train used for the MCP1631HV Multi-Chemistry Battery
Charger is a Single-Ended Primary Inductive Converter (SEPIC). The MCP1631HV
microcontroller is programmable, allowing the user to modify or develop their own
firmware routines to further evaluate the MCP1631HV Multi-Chemistry Battery Charger
in this application.

GETTING STARTED
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.
