MCP1631HV Multi-Chemistry Battery Charger Reference Design_2

Overview

TopologyOther Topology
IC revisionA

Description

The MCP1631HV Multi-Chemistry reference design board is used to charge one to five NiMH or NiCd batteries, charge one or two cell Li-Ion batteries, or drive one or two 1W LEDs. The board uses the MCP1631HV high speed analog PWM and PIC16F883 to generate the charge algorithm for NiMH, NiCd or Li-Ion batteries. The MCP1631HV Multi-Chemistry Battery Charger is used to evaluate Microchip’s MCP1631HV in a SEPIC power converter application. As provided, the MCP1631HV Multi-Chemistry Battery Charger is user programmable using on board push buttons. The board can charge NiMH, NiCd or Li-Ion batteries. The MCP1631HV Multi-Chemistry Battery Charger provides a constant current charge (Ni-based chemistry) and constant current / constant voltage (Li-Ion) with preconditioning, cell temperature monitoring (Ni-based) and battery pack fault monitoring. Also, the charger provides a status or fault indication. The MCP1631HV Multi-Chemistry Battery Charger automatically detects the insertion or removal of a battery pack.

Features

  • Input Operating Voltage Range - +5.3V to +16V
  • Maximum of 2A Charge Current for single cell Li-Ion
  • Charge NiMH, NiCd or Li-Ion Chemistries
  • Charge 1 cell or 2 cell Li-Ion Batteries in Series
  • Charge 1 cell to 5 cell NiMH or NiCd Batteries in Series
  • Drive one or two 1 Watt LEDs in series.
  • Select Chemistry and Cells using push-buttons
  • ON/OFF switch
  • Charge Status Indication
  • Programmable Charge Profile
  • Programmable Overvoltage Shutdown (1.8V/Cell for NiMH/NiCd or 4.4V/Cell for Li-Ion)
  • Complete “C” source code is provided
