The 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 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 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 TPS22918-Q1 features a
configurable quick output discharge (QOD) pin, which controls the fall time of the device to allow
design flexibility for power down and sequencing.
The TPS22918-Q1 is available in a small, leaded SOT-23 package (DBV) which allows to
visually inspect solder joints. The device is characterized for operation over the free-air
temperature range of –40°C to +105°C.
