3 Description
The TPS22968x-Q1 is a small, dual-channel load
switch with configurable rise time. The device
contains two N-channel MOSFETs that can operate
over an input voltage range of 0.8 V to 5.5 V and can
support a maximum continuous current of 4-A per
channel. Each switch is independently controlled by
an on/off input (ON1 and ON2), which is capable of
interfacing directly with low-voltage control signals.
The TPS22968-Q1 includes a 270 Ω on-chip resistor
for quick output discharge when the switch is turned
off.
The TPS22968x-Q1 is available in a small, space-
saving package (DMG) with wettable flanks and an
integrated thermal pad. The wettable flanks allow for
visual solder inspection. The device is characterized
for operation over the free-air temperature range of
–40 to +125°C.
