ADP198 Logic-Controlled, 1 A, High-Side Load Switch with Reverse Current Blocking
The ADP198 is a high-side load switch designed for operation
between 1.65 V to 6.5 V that is protected against reverse current
flow from output to input. A load switch provides power domain
isolation thereby helping to keep subsystems isolated and
powered independently, and enabling reduced power
consumption. The ADP198 contains a low on-resistance Pchannel
MOSFET that supports over 1 Amp of continuous load
current. The low 2.5μA quiescent current and ultra-low
shutdown current make the ADP198 ideal for battery-operated
portable equipment. The built-in level shifter for enable logic
makes the ADP198 compatible with modern processors and
GPIO controllers. The LFCSP version also allows the user to
program the start up time which control the inrush current at
turn on.
The ADP198 is available in an ultrasmall 1 mm × 1 mm, 4-ball,
0.5 mm pitch WLCSP. An 8-Lead 2 mm x 2 mm x 0.55 mm, 0.5
mm pitch LFCSP is also available.
