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. 1.5V to 5.5V Input Voltage Range Very Low RDS(ON), Typically 74mΩ (5V) Slew Rate Limited Turn-On Time 1ms (5V) Fast Shutdown Load Discharge TTL/CMOS Input Logic Level TDFN2X2-8 Package Applications 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.
