Description:

The TPS22810 is a single-channel load switch with a configurable rise time and an integrated quick output discharge (QOD) function. Additionally, the device features thermal shutdown protection to prevent excessively high junction temperatures, thereby internally ensuring operation within the safe operating area. The device includes an N-channel MOSFET and operates over an input voltage range of 2.7 V to 18 V. The SOT23-5 (DBV) package supports a maximum current of 2 A. The WSON (DRV) package supports a maximum current of 3 A. The switch is controlled by a switch input that can be directly connected to low-voltage control signals. The configurable rise time significantly reduces inrush current caused by large capacitive loads, thereby reducing or eliminating power supply voltage droop. Undervoltage lockout (UVLO) is used to turn off the device when the VIN voltage falls below a threshold, preventing downstream circuits from being damaged due to lower-than-expected supply voltage. The configurable fast output discharge (QOD) pin controls the device's fall time, allowing flexible design for power-down scenarios.
