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.
