3 Description
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
â40°C to +105°C.
