Load switch with configurable rise time and quick-output discharge

Texas Instruments’ TPS22918-Q1 is a single-channel load switch with both configurable rise time and configurable quick-output discharge. The device contains an N-channel MOSFET that can operate over an input voltage range of 1V to 5.5V and can support a maximum continuous current of 2A. The switch is controlled by an on and off input, which is capable of interfacing directly with low-voltage control signals. The configurable rise time of the device reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating power supply droop. The device features a configurable quick output discharge pin, which controls the fall time of the device to allow design flexibility for power down and sequencing. It is available in a small, leaded SOT-23 package (DBV) which allows to visually inspect solder joints. The device is characterised for operation over the free-air temperature range of –40C to +105C.
