3 Description

The TPS22810 is a single channel load switch with

configurable rise time and with an integrated quick

output discharge (QOD). In addition, the device

features thermal shutdown to protect the device

against high junction temperature. Because of this,

safe operating area of the device is inherently

ensured. The device contains an N-channel MOSFET

that can operate over an input voltage range of 2.7 V

to 18 V. SOT23-5 (DBV) package can support a

maximum current of 2 A. WSON (DRV) package can

support a maximum current of 3 A. The switch is

controlled by an on and off input, which is capable of

interfacing directly with low-voltage control signals.

The configurable rise time of the device greatly

reduces inrush current caused by large bulk load

capacitances, thereby reducing or eliminating power

supply droop. Undervoltage lock-out is used to turn

off the device if the VIN voltage drops below a

threshold value, ensuring that the downstream

circuitry is not damaged by being supplied by a

voltage lower than intended. The configurable QOD

pin controls the fall time of the device to allow design

flexibility for power down.

The TPS22810 is available in a leaded, SOT-23

package (DBV) which allows to visually inspect solder

joints, as well as a WSON package (DRV). The

device is characterized for operation over the free-air

temperature range of –40˚C to +105˚C.
