General Description
The G5283 is a dual P-channel MOSFET power
switch designed for high-side load-switching applica-
tions. Each MOSFET has a typical R_DS(ON) of 74mΩ at
V_CC=5V, allowing increased load switch current han-
dling capacity with a low forward voltage drop. The
G5283 has a slew rate limited turn-on load switch and
offers a shutdown load discharge circuit to rapidly turn
off a load circuit when the switch is disabled. An addi-
tional feature is a slew-rate selector pin which can
switch between fast and slow slew rate.
The G5283 operates with an input voltage from 1.5V
up to 5.5V. It is suitable for 1.8V, 3V and 5V systems.
Input logic levels are TTL and 2.5V to 5V CMOS
compatible. The typical quiescent supply current is
4µA each channel. In shutdown mode, the supply cur-
rent decreases to less than 1µA. The G5283 is avail-
able in a 8 pin TDFN 2X2mm package.
