MAX77751GEFG+T

Battery Chargers Overview

The MAX77751GEFG+T is a standalone lithium-ion battery charger featuring integrated USB Type-C CC detection and reverse boost capability. It supports a maximum charge current of 3.15A and operates with an input voltage range of 4.5V to 13.7V, with a maximum input current limit of 3A. The device includes adaptive input current limiting (AICL) to prevent adapter collapse. It offers reverse-boost output at 5.1V and 1.5A. The IC implements BC1.2 detection via D+/D- pins and runs autonomously without software upon plug insertion. It utilizes a Smart Power Selector and battery true-disconnect FET for power management. The component is housed in a 3mm x 3mm, 0.4mm pitch 24-lead FC2QFN package.

Battery Chargers Feature Summary

• Integrates USB Type-C configuration channel detection for automatic power source identification and input current configuration without software intervention.
• Features adaptive input current limiting to regulate input voltage and prevent weak adapter collapse or folding back during charging.
• Includes reverse-boost capability providing 5.1V output at 1.5A, enabled via the ENBST pin for host mode operation.
• Equipped with a Smart Power Selector and battery true-disconnect FET to manage power paths and isolate the battery during faults.

Battery Chargers Applications

• Mobile point-of-sale terminals
• Portable medical devices
• Wireless headphones
• GPS trackers
• Charging cradles for wearable devices

Battery Chargers Procurement Notes

Verify the specific suffix 'GEFG+T' against official Analog Devices documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with the 24-lead FC2QFN footprint. Cross-reference the part number with the manufacturer's current production status list, as availability may vary by region. Confirm RoHS compliance details directly from the datasheet before procurement.

Battery Chargers Selection Notes

Select this component for applications requiring autonomous USB Type-C charging without microcontroller overhead. It is suitable for designs needing integrated BC1.2 legacy support alongside modern USB-C standards. Consider the 3.15A charge current and 3mm x 3mm package size for space-constrained portable electronics. Evaluate the reverse-boost feature if host-mode power delivery is required.
