G5192CB11U--1-CH通道电源开关

General Description
The G5192C/D is a family of high-side load switches
designed to operation from 1.5V to 5V input voltage. The
load switch pass element is an internal 25 ohm RON
P-channel MOSFET which enable the device to support
up to 3A of continuous current. Additionally, the load
switch supports 1.5V.
Logic level control and shutdown features in a tiny 1mm X
1mm 4 pin WLCSP package.
The G5192C/D provide a slew rage controlled soft-start
turn on of 100μs. The soft-start feature is provided to
prevent an in-rush current event from pulling down the
input supply voltage.
The G5192C/D feature an active load discharge circuit
which switches in a 200Ω load when the switch is disabled
to automatically discharge a capacitive load.
An active pull-down on the enable input keeps the
G5192C/D in a default OFF state until the enable pin is
pulled above 1.2V. Internal level shift circuitry allows low
voltage logic signal to switch higher supply voltages.
The enable voltage can be as high as 5.5V and is not
limited by the input voltage.
The G5192C/D with reverse voltage block function, if the
VIN disappears or VIN is less than VOUT; device will turn
of without leakage current.
The G5192C/D operating voltage range makes them
ideal for Lithium ion and NMH/NiCad/Alkaline battery
powered systems as well as non-battery powered
applications. The device provides low quiescent current

and low shutdown current to maximize battery life.
