MCP73837 - (MCP73837 / MCP73838) Advanced Stand-Alone Li-Ion / Li-Polymer Battery Charge Management Controller

General Description

The MCP73837 and MCP73838 devices are fully integrated linear Li-Ion / Li-Polymer battery chargers with autonomous power source selection.

Along with its small physical size, the low number of external components required makes the MCP73837/8 ideally suitable for portable applications.

Key Features

  • High Accuracy Preset Voltage Regulation: + 0.5%.
  • Available Voltage Regulation Options: - 4.20V, 4.35V, 4.4V, or 4.5V.
  • Complete Linear Charge Management Controller: - Autonomous Power Source Selection - Integrated Pass Transistors - Integrated Current Sense - Integrated Reverse Discharge Protection.
  • Constant Current (CC) / Constant Voltage (CV) Operation with Thermal Regulation.
  • Selectable USB-Port Charge Current: - Low: 1 Unit Load / High: 5 Unit Loa.
