Texas Instruments  TPS22810TDBVRQ1

The TPS22810-Q1 is a one channel load switch with configurable rise time and integratedquick output discharge (QOD). The device features thermal shutdown to protect the device againsthigh junction temperature and thereby ensure safe operating area of the device inherently. Thedevice features a N-channel MOSFET that can operate over an input voltage range of 2.7 V to 18 V.The device can support a maximum current of 2 A. The switch is controlled by an on and off inputthat can interface directly with low-voltage control signals.

The configurable rise time of the device greatly reduces inrush current caused by largebulk load capacitances, thereby reducing or eliminating power supply droop. Undervoltage lock-outis used to turn off the device if the VIN voltage drops below a threshold value, ensuring that thedownstream circuitry is not damaged by being supplied by a voltage lower than intended. Theconfigurable QOD pin controls the fall time of the device to allow design flexibility for powerdown.

The TPS22810-Q1 is available in a leaded, SOT-23 package (DBV) which allows to visuallyinspect solder joints. The device is characterized for operation over the free-air temperaturerange of –40˚C to +105˚C.
