Product Details

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 con- figured to automatically start charging.
