3.15A USB Type-C Autonomous Charger with

MAX77787

JEITA for 1-Cell Li-ion/LiFePO4 Batteries

General Description

Benefits and Features

The MAX77787 is a standalone, 3.15A charger with

integrated USB Type-C CC detection and reverse-boost

•

Up to 16V Protection

13.4V Maximum Input Operating Voltage

3.15A Maximum Charging Current

capability. The fast-charge current and termination

voltage is easily configured with resistors. The IC operates

with an input voltage of 4.5V 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.

6A Discharge Current Protection

• No Firmware or Communication Required

• Integrated CC Detection for USB Type-C

• 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)

The USB Type-C Configuration Channel (CC) detection

pins on the IC enable automatic USB Type-C power

source detection and input current limit configuration

without any software control as soon as the USB plug is

inserted. The IC also integrates BC1.2 and proprietary

adapter detection using the D+ and D- pins.

•

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,

that can be enabled with the ENBST pin, also BYP

reverse-boost that can be enabled with the ENBST and

STBY pin combination. The STAT pin indicates charging

status, while the INOKB pin indicates valid input voltage.

Charging can be stopped by pulling the CHGENB pin low.

•

Pin Control of all Functions

• Resistor Configurable Fast-Charge Current/Input

Current Limit/Termination Voltage

• ENBST Pin to Enable and Disable Reverse Boost

• STAT Pin to Indicate Charging Status

• INOKB Pin to Indicate Input Power-OK

• CHGENB Pin to Enable and Disable Charging

• 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 batteries with JEITA

compliance. It also has another option that supports

LiFePO₄batteries with non-JEITA compliance. The IC

comes in a 2.758mm x 2.758mm, 0.4mm pitch, 6 x 6

wafer-level package (WLP) making it suitable for low-cost

PCB assembly.
