MCP73832

Tiny 500mA linear charge management controller. Includes integrated pass transostor, integrated current sensing, and reverse discharge protection in 5-pin SOT-23 and thermally-efficient 8-pin 2mm x 3mm DFN packages. Different than MCP73831 in the fact that the MCP73832 status output is open-drain.

Features
  • High accuracy preset output voltage regulation (+/-0.75%)
  • Output voltage options include 4.2V, 4.35V, 4.4V and 4.5V
  • User-programmable charge current
  • Open-drain status output
  • On-chip thermal regulation
  • Preconditioning and end-of-charge ratio options
  • Under-voltage lockout
