3.15A USB-C Autonomous Charger

for 1-Cell Li+ Batteries

19-100802; Rev 4; 11/20

General Description

The MAX77751 is a standalone, 3.15A charger with

integrated USB Type-C® CC detection and reverse

boost capability. The fast-charge current and top-off

current thresholds are easily configured with resistors.

The MAX77751 operates with an input voltage of 4.5V

to 13.7V and has a maximum input current limit of 3A.

The IC also implements the adaptive input current limit

(AICL) function that regulates the input voltage by

reducing input current, to prevent the voltage of a weak

adapter from collapsing or folding back.

The USB Type-C Configuration Channel (CC) detection

pins on the MAX77751 enable automatic USB Type C

configuration. To support a variety of legacy USB as well

as proprietary adapters, the IC also integrates BC1.2

detection using the D+ and D- pins. The IC runs the CC

detection and BC1.2 detection automatically without any

software as soon as the USB plug is inserted.

The IC also offers Reverse-Boost capability up to 5.1V,

1.5A, which can be enabled with the ENBST pin. The

STAT pin indicates charging status, while the INOKB pin

indicates valid input voltage. Charging can be stopped

by pulling the ITOPOFF pin low.

The MAX77751 is equipped with a Smart Power

Selector™ and a battery true-disconnect FET to control

the charging and discharging of the battery or isolate the

battery in case of a fault. The MAX77751 is offered in

several variants to support Li-ion batteries with various

termination voltages from 4.1V to 4.5V. The IC comes in

a 3mm x 3mm, 0.4mm pitch 24-lead FC2QFN package

making it suitable for low-cost PCB assembly.
