MAX77860

USB Type-C, 3A Switch-Mode Buck Charger

with Integrated CC Detection, Reverse Boost,

and ADC

General Description

Benefits and Features

The MAX77860 is a high-performance single input switch

mode charger that features USB Type-C CC detection ca-

pability in addition to reverse boost capability and a Safe-

out LDO.

● Single-Cell Switch Mode Charger

• Up to 14V Protection

• 4.0V to 13.5V Input Operating Range

• Switching Charger with D+/D- Charger Detection

• Up to 4.0A Input Current Limit with Adaptive Input

Current Limit (AICL)

• Up to 3.15A Battery Charging Current Limit

• Optional External Sense Resistor

• CC, CV, and Die Temperature Control

• Supports USB-OTG Reverse Boost, up to 1.5A

Current Limit

This switched-mode battery charger with two integrated

switches, provides small inductor and capacitor sizes, pro-

grammable battery charging current, and is ideally suited

for portable devices such as smartphones, IoT devices,

and other Li-ion battery powered electronics. The charger

features a single input, which works for both USB and high

voltage adapters. It supports USB Type-C CC detection

under BC 1.2 specification, and the power-path switch is

integrated in the chip. All MAX77860 blocks connected to

the adapter/USB pin are protected from input overvoltage

events up to 14V. The USB-OTG output provides true-

load disconnect and is protected by an adjustable output

current limit. It has an input current limit up to 4.0A and

can charge a single-cell battery up to 3.15A. When config-

ured in reverse-boost mode, the IC requires no additional

inductors to power USB-OTG accessories. The switching

charger is designed with a special CC, CV, and die tem-

ble settings to accommodate a wide range of battery sizes

and system loads. The on-chip ADC can help monitor the

charging input voltage/current, battery voltage, charging/

discharging current, and the battery temperature.

● I C-Compatible Interface

Ordering Information appears at end of data sheet.

The MAX77860 communicates through an I C 3.0 com-

patible serial interface consisting of a bidirectional serial

data line (SDA) and a serial clock line (SCL). The IC is

available in a 3.9mm x 4.0mm, 81-bump (9 x 9 array),

0.4mm pitch, wafer-level package (WLP).

Applications

● USB Type-C Charging for 1S Li-ion Applications

● Mobile Point-of-Sale Devices

● Portable Medical Equipment

● Portable Industrial Equipment
