Product Overview
The MCP73831T-2ACI/OT is a compact, high-efficiency linear charge management controller designed for single-cell Lithium-Ion (Li-Ion) and Lithium-Polymer (Li-Polymer) rechargeable batteries. It provides a fully integrated charging solution with automatic constant-current (CC) and constant-voltage (CV) charging profiles, eliminating the need for external MOSFETs, current-sense resistors, or reverse-blocking diodes. The device supports up to 500mA programmable charge current, features under-voltage lockout, thermal regulation, and charge status indication. With ultra-small form factor and low power consumption, it is ideal for portable electronics, wearables, and IoT devices. Housed in a tiny SOT-23-5 package, it enables space-constrained PCB designs.
