MCP73223 - Lithium Iron Phosphate (LiFePO4) Battery Charge Management Controller

Download the MCP73223 datasheet PDF. This datasheet also covers the MCP73123 variant, as both devices belong to the same lithium iron phosphate (lifepo4) battery charge management controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The MCP73123/223 is a highly integrated Lithium Iron Phosphate (LiFePO4) battery charge management controller for use in space-limited and cost-sensitive applications.

Key Features

  • Complete Linear Charge Management Controller: - Integrated Input Overvoltage Protection (OVP) - Integrated Pass Transistor - Integrated Current Sense - Integrated Reverse Discharge Protection.
  • Constant Current/Constant Voltage Operation with Thermal Regulation.
  • 4.15V Undervoltage Lockout (UVLO).
  • 18V Absolute Maximum Input with OVP: - 6.5V - MCP73123 - 13V - MCP73223.
  • High Accuracy Preset Voltage Regulation Through Full Temperature Range (-5°C to +55.
