MCP73871 - Stand-Alone System Load Sharing and Li-Ion / Li-Polymer Battery Charge Management Controller

General Description

The MCP73871 device is a fully integrated linear solution for system load sharing and Li-Ion/Li-Polymer battery charge management with AC-DC wall adapter and USB port power sources selection.

It is also capable of autonomous power source selection between input and battery.

Key Features

  • Integrated System Load Sharing and Battery Charge Management - Simultaneously Power the System and Charge the Li-Ion Battery - Voltage Proportional Current Control (VPCC) ensures system load has priority over Li-Ion battery charge current - Low-Loss Power-Path Management with Ideal Diode Operation.
  • Complete Linear Charge Management Controller - Integrated Pass Transistors - Integrated Current Sense - Integrated Reverse Discharge Protection - Selectable Input Power Sources: USB.
