nPM6001 Power Management IC
Multi-Rail for advanced applications
The nPM6001 is a dedicated power management IC (PMIC) with six independently controlled power rails. It is designed for complex applications architected with multiple power domains that require separate voltage regulation or need to be powered down independently to conserve application power. With 3 out of the 4 buck regulators enabled, the typical operational quiescent current of the PMIC is only 1.2 µA.
The PMIC includes a watchdog timer that can be set to time out between 4 seconds and 2 years in 4-second steps. It also includes a hibernate mode.
