DESCRIPTION
The TPS22960 is a small low-r_ON dual 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.
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.
