3 Description
The TPS22966-Q1 device is a small, ultralow R_ON,
dual-channel load switch with adjustable 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 up to 4 A per channel. Each switch is
independently controlled by an on/off input (ON1 and
ON2), which can interface directly with low-voltage
control signals. The TPS22966-Q1 includes a 230-Ω
on-chip resistor for quick output discharge when the
switch is turned off.
The TPS22966-Q1 is available in a small, space-
saving 2-mm × 3-mm 14-SON package (DPU) with
integrated thermal pad allowing for high power
dissipation. The device is characterized for operation
over the free-air temperature range of –40°C to
105°C.
