Integrated FETs for 2S Li-Ion Batteries

General Description

Benefits and Features

The MAX77962 is a high-performance wide-input 3.2A

buck-boost charger with a Smart Power Selector™ and

operates as a reverse buck without an additional inductor,

allowing the IC to power USB On-the-Go (OTG) acces-

sories. The device integrates low-loss power switches,

and provides small solution size, high efficiency, low heat,

and fast battery charging. The reverse buck has true-load

disconnect and is protected by an adjustable output cur-

rent limit. The device is highly flexible and programmable

through I C configuration or autonomously through resis-

tor configuration.

● Charge Safety Timer

● Die Temperature Regulation with Thermal Foldback

● Input Power Management with Adaptive Input Current

Limit (AICL) and Input Voltage Regulation

● 10mΩ BATT to SYS Switch, Up to 10A Overcurrent

Threshold

The battery charger includes a Smart Power Selector to

accommodate a wide range of battery sizes and system

loads. The Smart Power Selector allows the system to

start up gracefully when an input source is available even

when the battery is deeply discharged (dead battery) or

missing. For battery safety/authentication reasons, the IC

can be configured to keep charging disabled, and allow

the DC-DC to switch and regulate the SYS voltage. The

system processor can later enable charging using the ap-

● JEITA Compliant with NTC Thermistor Monitor

propriate I C commands. Alternatively, the IC can be con-

figured to automatically start charging.

● 3.458mm x 3.458mm 49-Bump WLP
