MAX77751CEFG+ Description

Short technical summary and product information.

The MAX77751CEFG+ is a standalone, 3.15A autonomous charger designed for 1-cell Li+ batteries, featuring integrated USB Type-C CC detection and reverse boost capability. It supports an input voltage range of 4.5V to 13.7V with a maximum input current limit of 3A. The device implements an adaptive input current limit (AICL) function for voltage regulation.

 

Key features include automatic USB Type-C power source detection and input current limit configuration, as well as BC1.2 detection for legacy USB adapters. The IC offers reverse boost capability up to 5.1V at 1.5A, controlled via the ENBST pin. Charging status is indicated by the STAT pin, and input power validity by the INOKB pin.

 

Designed for low-cost PCB assembly, the MAX77751CEFG+ comes in a compact 3mm x 3mm, 0.4mm pitch 24-lead FC2QFN package. It is suitable for applications such as mPOS terminals, portable medical devices, wireless headphones, GPS trackers, charging cradles for wearable devices, power banks, and mobile routers.
