3 Description
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.
