DESCRIPTION

OUT2

The TPS22960 is a small low-r_ONdual load switch

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.

OUT1

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 for operation over the free-air

temperature range of –40°C to 85°C.
