3 Description

The

TPS22976

product

family

consists

of

two

devices: TPS22976 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.
