General Description
The G5198 is a N-channel MOSFET power switch
designed for high-side load-switching applications, and
the device has a typical R_DS(ON) of 12m and the output
current is limited to 9A.The G5198 has a programma-
ble turn-on load switch and offers a shutdown load
discharge circuit to rapidly turn off a load circuit when
the switch is disabled.
The G5198 operates with an input voltage ranging
from 0.6V to 5.5V. The G5198 also features an under
voltage lock out which turns the switch off when an
input under-voltage condition exists. In shutdown
mode, the supply current decreases to about 2µA. The
G5198 is available in 8 pin ADFN package.
