General Description
The G5285 is a N-channel MOSFET power switch
designed for high-side load-switching applications, and
the device has a typical R_DS(ON) of 85mΩ and the out-
put current is limited to 2A.The G5285 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 G5285 operates with an input voltage ranging
from 2.0V to 5.5V. It is suitable for both 3V and 5V
systems. The G5285 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
G5285 is available in a SOT-23-5 package.
