3 Description

The TPS22976 product family consists of three

devices: TPS22976, TPS22976A and TPS22976N.

Each device 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 0.6 V to 5.7 V, and can support a maximum

continuous current of 6 A 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 TPS22976 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 TPS22976 also offers

an optional integrated 230-Ω on-chip load resistor for

quick output discharge when the switch is turned off.

The TPS22976 is available in a small, space-

saving 3-mm × 2-mm 14-SON package (DPU) with

integrated thermal pad allowing for high power

dissipation. The device is characterized for operation

over the free-air temperature range of –40°C to

105°C.
