3 Description

The TPS22960 is a small low-rON dual-channel load

switch with controlled turnon. The devices contain

two P-channel MOSFETs that can operate over an

input voltage range of 1.62V to 5.5V. Each switch is

independently controlled by on/off inputs (ON1 and

ON2), which are capable of interfacing directly with

low-voltage control signals. In TPS22960 a 85Ω onchip

load resistor is added for quick discharge when

the switch is turned off.

The rise time (slew-rate) of the device is internally

controlled in order to avoid inrush current, and it can

be slowed down if needed using the SR pin: at 3.3V,

TPS22960 features a 75μs rise time with the SR pin

tied to ground and 660μs with the SR pin tied to high.

The TPS22960 is available in a space-saving 8-

pin UQFN package and in an 8-pin SOT package.

It is characterized for operation over the free-air

temperature range of –40°C to 85°C.
