MCP1630 Li-Ion Multi Bay Battery Charger Reference Design (MCP1630RD-LIC1)

The MCP1630 Multi-Bay Li-Ion Charger is used to evaluate Microchip’s MCP1630 used in a SEPIC power converter application. The MCP1630 Multi-Bay Li-Ion Charger is capable of charging two single-cell, Li-Ion battery packs in parallel utilizing an input voltage of 10V to 30V (battery packs are not included). Multiple boards can be daisy-chained for additional charger bays. The MCP1630 Multi-Bay Li-Ion Charger is intended for use in pseudo-smart battery charger applications utilizing battery packs containing Microchip’s PS700 Battery Monitor. Standard battery packs can be utilized as well. The MCP1630 Multi-Bay Li-Ion Charger provides a constant current - constant voltage charge with preconditioning, cell temperature monitoring, and battery pack fault monitoring. Each charger bay provides a status and fault indication. The MCP1630 Multi-Bay Li-Ion Charger automatically detects the insertion or removal of a battery pack.

Возможности

    • Over Voltage Protection (battery removed).
    • Over Charge Protection to prevent the battery from becoming dangerously overcharged.
    • Over Current Protection in the event of a shorted battery.
    • Battery Reversal Protection.
    • Input Short Circuit Protection.
    • 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 Multi-Bay Li-Ion Charger terminates charge by detecting a predefined charge current threshold during constant voltage charge, or a specified elapsed time.
    • The MCP1630 Multi-Bay Li-Ion Charger has the flexibility to optimize the charging algorithm for new battery technology and add proprietary features by coding the microcontroller.
    • Programmed parameters - modified in firmware

    Factory Settings:

    Preconditioning Charge Current = 200 mA
    Preconditioning Threshold = 3V
    Constant Current Fast Charge = 2A
    Constant Voltage Charge = 4.2 V
    Charge Termination Threshold = 100 mA
