nPM6001 Power Management IC

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 hibernate mode.  

Thermal protection protects the device from overheating. It will turn off the device and allow it to cool down should it reach critical temperatures. It will send a pre-warning interrupt to the host to allow it to reduce the PMIC load and avoid being reset.
