The TPS22918 is a single-channel load switch with 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
The configurable rise time of the device greatly reduces inrush current caused by large
bulk load capacitances, thereby reducing or eliminating power supply droop. The TPS22918 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 is available in a small, leaded SOT-23 package (DBV) which allows visual
inspection of solder joints. The device is characterized for operation over the free-air
temperature range of –40°C to +105°C.
