INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
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 duty cycle and provides fast overcurrent protection based off various
external inputs. External signals include the input 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.
The MCP1631HV Multi-Chemistry Battery Charger has the following features:
• Input Operating Voltage Range
• Maximum of 2A Charge Current for single cell Li-Ion
• Charge NiMH, NiCd or Li-Ion Chemisties
• Charge 1 or 2 Cell Li-Ion Batteries in Series
• Charge 1 to 4 Cells of NiMH or NiCd Batteries in Series
• Select Chemistry and Cells using push-buttons
• ON/OFF switch
• Charge Status Indication
• Programmable Charge Profile
• OV Shutdown (2.0V / Cell for NiMH/NiCd or 4.4V/Cell for Li-Ion)
