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 1.62 V to 5.5 V. 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 85-on-
chip 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 3.3 V,
TPS22960 features 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
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.
