Description
General part information
TPS7H2221-SEP Series
The TPS7H2221-SEP 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 1.25 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 (VON>VIH), the Smart Pull Down will be disconnected to prevent unnecessary power loss.
The TPS7H2221-SEP load switch is also self-protected, meaning that it protects against short circuit events on the output of the device.
