The MAX77654 provides battery charging and power solutions for low-power applications where size and efficiency are critical. This highly integrated device features a buck-boost regulator with three independently programmable power rails from a single inductor to minimize the overall solution size. Two 100 mA LDOs provide ripple rejection for audio and other noise-sensitive applications. The configurable linear charger supports multiple Li-Ion battery capacities and includes battery temperature monitoring for increased safety (JEITA).

Three GPIOs and an analog multiplexer enable users to switch multiple internal voltage and current signals to external nodes for monitoring with an external ADC. Numerous factory-programmable options allow the device to be customized for a variety of applications, reducing time-to-market.
