Power Distribution Switches TPS22918DBVT Power Switch/Driver 1:1 N-Channel 2A SOT-23-6

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 control signals. 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.
