Features
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
Cellular Telephones Digital Still Cameras Hot Swap Supplies Notebook Computers Personal Communication Devices Personal Digital Assistants (PDAs) 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 74m Ω at VCC=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 1 µA. The G5283 is avail- able in a 8 pin TDFN 2X2mm package.
