Description

The TPS22918-Q1 is a single-channel load switch with both configurable rise time andconfigurable quick-output discharge. The device contains an N-channel MOSFET that can operate overan input voltage range of 1 V to 5.5 V and can support a maximum continuous current of
2 A. The switch is controlled by an on and off input, which is capable of interfacingdirectly with low-voltage control signals.

The configurable rise time of the device reduces inrush current caused by large bulk loadcapacitances, thereby reducing or eliminating power supply droop. The TPS22918-Q1 features aconfigurable quick output discharge (QOD) pin, which controls the fall time of the device to allowdesign flexibility for power down and sequencing.

The TPS22918-Q1 is available in a small, leaded SOT-23 package (DBV) which allows tovisually inspect solder joints. The device is characterized for operation over the free-airtemperature range of –40°C to +105°C.
