• 8-Pin µQFN (RSE) Package: 1.5 mm × 1.5 mm

with controlled turn on. The devices contain two

P-channel MOSFETs that can operate over an input

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

controlled by an on/off input (ON1 and ON2), which is

capable of interfacing directly with low-voltage control

signals. In TPS22960 a 85-

Ω on-chip load resistor is

added for output quick discharge when switch is

turned off.

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

controlled in order to avoid inrush current and can be

slowed down if needed using the SR pin: TPS22960

feature a 75

µs rise time with the SR pin tied to

ground and 660

µs with the SR pin tied to high.

The TPS22960 is available in a space-saving 8-pin

µQFN package and in an 8-pin SOT package. It is

characterized

This feature discharges the output of the switch to ground through a 85-

Ω resistor, preventing the output from floating.
