Description

The TPS22997 is a single-channel load switch that 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 0.1 V to 5.5 V and can support a maximum continuous current of 10 A.

The switch is controlled by an enable pin (ON), which is capable of interfacing directly with low voltage GPIO signals (V_IH = 0.8 V). The TPS22997 device has an optional QOD pin for quick output discharge when switch is turned off, and the fall time (t_FALL) of the output can be adjusted through an external resistor. There is a Power Good (PG) signal on the device that indicates when the main MOSFET is fully turned on, which can be used to enable a downstream load. Integrated thermal shutdown ensures protection in high temperature environments.

The TPS22997 is available in a 1.5 × 2.0 mm, 0.5 mm pitch, 10-pin WQFN package (RYZ) and is characterized for operation over the free-air temperature range of –40°C to +125°C.
