MCP1630RD-LIC2 - 

The MCP1630 Low Cost Li-Ion Battery Charger is used to evaluate Microchips 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 6 V to 18 V (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 = 3 V
- Constant Current Fast Charge = 2 A
- Constant Voltage Charge = 4.2 V
- 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
- Over temperature 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
