Devices Supported: MCP1630

Summary Description:

The MCP1630 Low Cost Li-Ion Battery Charger is used to evaluate Microchip’s MCP1630 used in a SEPIC power converter application. The MCP1630 Low Cost Li-Ion Charger is capable of charging a single-cell, Li-Ion battery pack utilizing an input voltage of 6V to 18V (battery packs are not included). The MCP1630 Low Cost Li-Ion Battery Charger provides a constant current - constant voltage charge with preconditioning, cell temperature monitoring, and battery pack fault monitoring. The battery charger provides a status and fault indication. The MCP1630 Low Cost Li-Ion Battery Charger automatically detects the insertion or removal of a battery pack.

Features:

• Programmed parameters - modified in firmware
• Factory Settings:
  • Preconditioning Charge Current = 200 mA
  • Preconditioning Threshold = 3V
  • Constant Current Fast Charge = 2A
  • Constant Voltage Charge = 4.2V
  • Charge Termination Threshold = 100 mA
• Overvoltage protection (battery removed)
• Over charge protection to prevent the battery from becoming dangerously overcharged
• Over current protection in the event of a shorted battery
• Overtemperature protection to prevent the battery from reaching too high a temperature during charge
• Fast charge termination if the battery temperature is outside a preset window
• Controlled soft-start
• The MCP1630 Low Cost Li-Ion Battery Charger terminates charge by detecting a predefined charge current threshold during constant voltage charge, or a specified elapsed time
• The MCP1630 Low Cost Li-Ion Battery Charger has the flexibility to optimize the charging algorithm for new battery technology and add proprietary features by coding the microcontroller
