G5283
Global Mixed-mode Technology Inc.
Dual Slew Rate Controlled Load Switch
Features
General Description
„
The G5283 is a dual P-channel MOSFET power
switch designed for high-side load-switching applications. Each MOSFET has a typical RDS(ON) of 74mΩ at
VCC=5V, allowing increased load switch current handling 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 additional 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 current decreases to less than 1µA. The G5283 is available in a 8 pin TDFN 2X2mm package.
