The TPS22999 is a single-channel load switch that is designed to achieve a fast turn-on time while keeping a low inrush current The device contains an N-channel MOSFET that can operate over an input voltage range of 0.1 V to VBIAS –1.0 V and can support a maximum continuous current of 1.5 A.

The switch is controlled by an enable pin (EN), which is capable of interfacing directly with low voltage GPIO signals (VIH = 0.8 V). The TPS22999 device has an integrated 5.3-Ω quick output discharge path when the switch is turned off to enable reliable system operation. There is a Power-Good (PG) signal on the device that indicates when the main MOSFET has fully settled to the lowest resistance path , which can be used to enable a downstream load. Integrated thermal shutdown makes sure of protection in high temperature environments.

The TPS22999 is available in a 0.35 mm pitch, 8-pin WCSP package (YCH) and is characterized for operation over the free-air temperature range of –40°C to +105°C.
