描述 Description

The ET3148 advanced load management switches target applications requiring a highly integrated solution it disconnects loads powered from DC Power Rail (<6V) with stringent off-state current targets and high load capacitances (up to 200μF). Each switch consists of slew-rate controlled low-impedance MOSFET Switch (23mΩ 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.
The ET3148 has True Reverse Current Blocking(TRCB) function blocking unwanted reverse current from VOUT to VIN during ON/OFF state. 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 1.5V 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.
The device is packaged in advanced full-Green compliant 1mmx1.5mm Wafer Level Chip Scale Packaging (WLCSP).
