MAX77789

14VIN, 3AOUT 1-Cell Charger with Integrated

USB Type-C Detection, DRP, and OTG

General Description

Benefits and Features

The MAX77789 is a standalone, 3.15A charger with

integrated USB Type-C CC detection and reverse-

•

Up to 16V Protection

13.4V Maximum Input Operating Voltage

3.15A Maximum Charging Current

6A Discharge Current Protection

Integrated CC Detection for USB Type-C

Supporting Dual Role Port (DRP)

DP/DN Manual Control for the HVDCP

Integrated BC1.2 Detection for Legacy SDP, DCP,

CDP, and DCD Timeout

Integrated USB Detection for Common Proprietary

Charger Types

Automatic Input Current Limit Configuration

Input Voltage Regulation with Adaptive Input Current

Limit (AICL)

boost capability. The IC operates with an input voltage

of 4.6V to 13.4V 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 IC is operating in DRP (Dual Role Port) as a

default and is capable of automatic USB Type-C power

source detection and sink devices. To support a variety

of legacy USB as well as proprietary adapters, the

device also integrates BC1.2 detection using the D+ and

D- pins. The IC runs the CC pin and BC1.2 detection

automatically as soon as the USB plug is inserted

without any software control.

5.1V, 1.5A OTG Mode and BYP Reverse Boost

Safety

• Charge Safety Timer

• JEITA Compliance with NTC Thermistor Monitor

• Thermal Shutdown

The IC offers reverse-boost capability up to 5.1V, 1.5A,

which can be enabled with automatic way or register set

by system MCU. The STAT1 pin indicates charging

status, while the INOKB pin indicates valid input voltage.

The EXTSM pin can be used to exit ship mode and force

system to reset (POR), and STAT2 pin indicates fault

detection and charger detection done indication by

Pin Control of all Functions

• STAT1 Pin to Indicate Charging Status

• STAT2 Pin to Indicate Fault and Charger Type

Detection Complete

• INOKB Pin to Indicate Input Power-OK

• EXTSM Pin to Exit Ship Mode and System POR

• STBY Pin to Support Suspend Mode

• THM Pin to Monitor Thermistor

The IC 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 IC supports Li-ion and LiFePO₄

batteries with various termination voltages from 3.6V to

4.55V. The IC comes in a 2.85mm x 2.85mm, 0.4mm

pitch, 6 x 6 wafer-level package (WLP) making it suitable

for low-cost PCB assembly.
