description: |
  Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
  integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
  GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
  The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
  fuel gauge, and an ADC.
  The RC5T619 additionally includes USB charger detection and an RTC.
