description: |
  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.

      BD71815 has SAR ADC for measuring charging currents. External sense
      resistor (RSENSE in data sheet) should be used. If something other
      but a 30 mOhm resistor is used the resistance value should be given
      here in micro Ohms.
