+ BD71815AGW is a single-chip power management ICs for battery-powered
+ portable devices. It integrates 5 buck converters, 8 LDOs, a boost driver
+ for LED and a 500 mA single-cell linear charger. Also included is a Coulomb
+ counter, a real-time clock (RTC), and a 32.768 kHz clock gate and two GPOs.
