Texas Instruments TPS22998 Single-Channel Load Switch
Texas Instruments TPS22998 Single-Channel Load Switch provides a configurable rise time to minimize inrush current. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.2V to 5.5V and supports a maximum continuous current of 10A.
The switch is controlled by an on and off input (ON), which can interface directly with low voltage control signals (VIH = 0.9V). The TPS22998 has a fixed quick output discharge when the switch is turned off, pulling the output down to ground.
The Texas Instruments TPS22998 is available in a 1.5mm × 2.0mm, 0.5mm pitch, 10-pin WQFN package (RYZ) and is characterized for operation over the free-air temperature range of –40°C to +105°C.
