The ET3138A advanced load management switches target applications requiring a highly integrated solution it disconnects loads powered from DC Power Rail (< 5.5V) with stringent off-state current targets. Each switch consists of slew-rate controlled low-impedance MOSFET Switch (30mΩ Typ) and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush-current and the resulting excessive voltage droop on power rails.
These devices have exceptionally low off-state current drain (< 1μA max) which facilitate compliance in very low stand-by power applications. The input voltage range operates from 1.2V to 5.5V DC to fulfill a wide range of applications in consumer, optical, medical, storage, portable, and industrial device power management. Switch control is managed by a logic input (Active HIGH) capable of interfacing directly with low voltage control signal/GPIO with no external pull-down resistor required.
