MCHPMCP73837-FCI/MF
Overview
The MCP73837-FCI/MF is a highly integrated Li-Ion battery charge management controller with autonomous power path selection. It is designed to automatically manage charging from either a USB port or an AC-to-DC wall adapter, supporting charge currents up to 1A.
Why Choose This Part
This controller features a Power-Good output for system-level status monitoring and supports automatic switching between input sources without microcontroller intervention. It includes integrated thermal regulation that throttles the charge current to maintain safe operating temperatures in space-constrained designs.
Applications
Getting Started
To evaluate this device, use the MCP73837EV evaluation board to test the autonomous switching between USB and DC inputs. Ensure the thermal pad is properly soldered to a ground plane to manage heat dissipation during 1A charging cycles.
