# MAX77962EWJ12+T (Component)
## Description
Charger IC Lithium Ion 49-WLP (3.46x3.46)
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) accessories. 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 current limit. The device is highly flexible and programmable
through I2C configuration or autonomously through resistor configuration.
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 appropriate I2C commands. Alternatively, the IC can be configured to automatically start charging.
