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.
