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.
