Working Principle

The NUD3160LT1 is an advanced PMIC that is capable of providing precise control over all aspects of power distribution and system power management, including power sequencing, over-current protection, over-voltage protection, and power-saving features. The NUD3160LT1 includes an integrated voltage monitor, two independent current sense pins, and four N-channel MOSFETs to provide over-current protection. The NUD3160LT1 also has four adjustable level voltage comparators, a separate voltage regulator input, and a programmable timer for complete system power management. The NUD3160LT1 also supports power sequencing which allows for the controlled release of power when multiple loads are connected to the same power source.

The NUD3160LT1 can also be used as a load switch to control the on/off switching of multiple external loads. The NUD3160LT1 implements a dynamic current-sensing technique to detect over-current conditions and shut off the power to the loads when an over-current condition is detected. The NUD3160LT1 also provides an adjustable current limit, programmable soft start, and over-voltage protection. Finally, the NUD3160LT1 provides power-saving features such as adjustable power-down delays, adjustable power-down protection thresholds, and adjustable power-loss debounce timers.
