Product Overview

The MCP73123-22SI/MF is a single cell highly integrated LiFePO4 (lithium iron phosphate) Battery Charge Management Controller for use in space-limited applications. The MCP73123 can accept an absolute maximum of 18V input and provides a 6.5V overvoltage protection. The output current can is programmable to be between 130mA and 1.1A. The MCP73123 is specified over the ambient temperature range of -40 to +85°C. The MCP73123 employs a constant current/constant voltage charge algorithm. The 3.6V per cell factory preset reference voltage simplifies design with 2V preconditioning threshold. The MCP73123 also limits the charge current based on die temperature during high power or high ambient conditions. This thermal regulation optimizes the charge cycle time while maintaining device reliability.
  • Integrated input overvoltage protection
  • Integrated pass transistor
  • Integrated current sense
  • Integrated reverse discharge protection
  • Constant current/constant voltage operation with thermal regulation
  • 4.15V Under-voltage lockout (UVLO)
  • Preconditioning of deeply depleted cells 10% or disable
  • Integrated precondition timer, 32 minutes or disable
  • Automatic end-of-charge control
  • Factory preset charge status output - on/off or flashing
  • Soft start
