General Description
The G5281 is a N-channel MOSFET power switch
designed for high-side load-switching applications, and
the device has a typical R_DS(ON) of 80m and the output
current is limited to 2A.The G5281 has a slew rate
limited turnon load switch and offers a shutdown load
discharge circuit to rapidly turn off a load circuit when
the switch is disabled.
The G5281 operates with an input voltage ranging
from 2V to 5.5V. It is suitable for both 3V and 5V sys-
tems. The G5281 also features an under voltage lock
out which turns the switch off when an input un-
der-voltage condition exists. Input logic levels are TTL
and 2.5V to 5V CMOS compatible. In shutdown mode,
the supply current decreases to less than 1µA.The
G5281 is available in a 8 pin TDFN package.
