3 Description
The TPS22919-Q1 device is a small, single channel
load switch with controlled slew rate. The device
contains an N-channel MOSFET that can operate
over an input voltage range of 1.6 V to 5.5 V and can
support a maximum continuous current of 1.5 A.
The switch ON state is controlled by a digital input
that is capable of interfacing directly with low-voltage
control signals. When power is first applied, a Smart
Pull Down is used to keep the ON pin from floating
until system sequencing is complete. Once the pin is
deliberately driven High (>VIH), the Smart Pull Down
will be disconnected to prevent unnecessary power
loss.
The TPS22919-Q1 load switch is also self-protected,
meaning that it will protect itself from short circuit
events on the output of the device. It also has thermal
shutdown to prevent any damage from overheating.
TPS22919-Q1 is available in a standard SC-70
package characterized for operation over a junction
temperature range of –40°C to 125°C.
