Description

The

are current limited P-channel MOSFET power switch designed for high-side load switching

applications. This switch operates with inputs ranging from 2.5V to 5.5V, making it ideal for both 3.3V and 5V systems. An

integrated current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of

regulation.The

is also protected from thermal overload which limits power dissipation and junction temperatures.

Current limit threshold is fixed internally. The quiescent supply current in active mode is only 25μA. In shutdown mode, the

supply current decreases to less than 1μA.

The

range.
