General Description
The G5255 is a current limited N-channel MOSFET power switch designed for highside load switching applications. The low RDS(ON) N-channel power MOSFET is driven by a built-in charge pump which generates a voltage higher than the supply voltage to fully enhance the switch.
This switch operates with inputs ranging from 2.7V to 5.5V, making it ideal for both 3.3V and 5V systems. An integrated current-limiting circuit protects the input supply against large current which may cause the supply to ...
