The MAX77278 provides a highly-integrated battery charging and power supply solution for low-power applications where size and efficiency are critical.The device features a single-inductor multiple-output (SIMO) buck-boost regulator that provides three independently programmable power rails from a single inductor to minimize total solution size. A 50mA LDO provides ripple rejection for audio and other noise-sensitive applications. A highly-configurable linear charger supports a wide range of Li+ battery capacities and includes battery temperature monitoring for additional safety (JEITA).The device includes other features such as a programmable current sink that can be used to drive an IR-LED, 8 general-purpose input/output (GPIO) control pins, and an analog multiplex (AMUX) output that provides access to useful battery charging signals. A bidirectional I2C interface allows for configuring and checking the status of the device. An internal on/off controller provides a controlled startup sequence for the regulators and provides supervisory functionality when the device is on. Numerous factory programmable options allow the device to be tailored for many applications, enabling faster time to market.Design Solution: Choose a Tailored SIMO PMIC for Your Portable Design ›ApplicationsInternet of Things (IoT) GadgetsRemote Controls, Game Pads, Media Center ControllersSmart Home Automation Pads, Thermostats, Battery-Powered User InterfacesWearables, Fitness and Health Monitors
