12description: |
13  Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
14  integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
15  GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
16  The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
17  fuel gauge, and an ADC.
18  The RC5T619 additionally includes USB charger detection and an RTC.
