3 Description

TPS22996H-Q1 is a dual-channel load switch with

controlled turnon. The device contains two N-channel

MOSFETs that can operate over an input voltage

range of 0.6V to 5.5V, and can support a maximum

continuous current of 4A per channel. Each switch

is independently controlled by an on and off input

(ON1 and ON2), which can interface directly with

low-voltage control signals. The device is capable

of thermal shutdown when the junction temperature

is above the threshold, turning the switch off. The

switch turns on again when the junction temperature

stabilizes to a safe range. The device also offers an

integrated 230Ω on-chip load resistor for quick output

discharge when the switch is turned off.

The pins of the TPS22996H-Q1 are resistant to high

humidity conditions, meaning that the device is able to

function with a 100kΩ short from any pin to GND or

power.

The TPS22996H-Q1 is available in a small, spacesaving

2.1mm × 1.2mm 8-DYC package. The device

is characterized for operation over the free-air

temperature range of –40°C to 125°C.
