MAX77960B is a high-performance wide-input 3A buckboost charger with Smart Power Selector� and operate as a reverse buck converter without an additional inductor, allowing the ICs to power USB OTG accessories. The devices integrate low-loss power switches and provide high efficiency, low heat and fast battery charging in a small solution size. The reverse buck has true load disconnect and is protected by an adjustable output current limit. The devices are highly flexible and programmable through I2C configuration or autonomously through resistor configuration. The battery charger includes the Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start up smoothly when an input source is available even when the battery is deeply discharged/missing. For battery safety/authentication reasons, the ICs can be configured to keep charging disabled and allow the DC-DC to switch and regulate the SYS voltage.
