General Description
2.0V to 5.5V Input Voltage Range
Very Low RDS(ON) , Typically 80m. (5V)
Typical Current Limited is 2.5A at VCC=5V
Slew Rate Limited Turn-On Time 1.5ms (5V)
Fast Shutdown Load Discharge
TTL/CMOS Input Logic Level
No Reverse Output Current
8 Pin TDFN Package
The G5281 is a N-channel MOSFET power switch
designed for high-side load-switching applications, and
the device has a typical RDS(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 systems. The G5281 also features an under voltage lock
out which turns the switch off when an input under-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.
