MCP1630 NiMH BATTERY CHARGER
DEMO BOARD USER ’S GUIDE
Chapter 2. Installation and Operation

INTRODUCTION
The MCP1630 NiMH Battery Charger Demo Board demonstrates Microchip’s
MCP1630 high-speed Pulse Width Modulator (PWM) used in a smart battery charger
application. The MCP1630 is a high-speed, microcontroller-adaptable PWM that, when
used in conjunction with a microcontroller, will control the power system duty cycle to
provide output voltage or current regulation. The PIC16LF818 microcontroller can be
used to regulate output voltage or current, switching frequency and maximum duty
cycle. The MCP1630 generates pulse-by-pulse duty cycle, provides fast overcurrent
protection and utilizes variable external inputs. External signals include the input
oscillator and the reference voltage. The power train signals include the current sense
and the feedback voltage; the output signal is a square-wave pulse. The power train
used for the MCP1630 NiMH Battery Charger Demo Board is a Single-Ended Primary
Inductive Converter (SEPIC).
FEATURES
The MCP1630 NiMH Battery Charger Demo Board has the following features:
? Programmed charge currents:
- Fast Charge = 500 mA
- Trickle Charge = 50 mA
- Top-Off Charge = 25 mA
? Overvoltage protection (battery removed)
? Overcharge protection to prevent the battery from becoming dangerously
overcharged
? Overdischarge protection to prevent the battery from being damaged
? Overcurrent protection in the event of a shorted battery
? Battery reversal protection
? Input short circuit protection
? Fast charge termination if the battery or ambient temperature is too high
? Soft-start capability by holding the reference voltage low during power-up
? The MCP1630 NiMH Battery Charger Demo Board terminates charge by detect-
ing a predefined change in voltage with respect to time, a specified temperature or
specified elapsed time
? A simple fuel gauge that has a dual MCP6042 amplifier, a 1-channel sense
voltage and a 1-channel sense current
? The MCP1630 NiMH Battery Charger Demo Board has the flexibility to optimize
the charging algorithm for new battery technology and add proprietary features by
coding the microcontroller
? Ability to adapt to environmental effects, such as ambient temperature
? Uses a very low standby current of 29 μ A
