3 Description
The TPS22976 product family consists of two
devices: TPS22976 and TPS22976N. Each device is
a dual-channel load switch with controlled turnon. The
device contains two N-channel MOSFETs that can
operate over an input voltage range of 0.6 V to 5.7 V,
and can support a maximum continuous current of 6
A per channel. Each switch is independently
controlled by an on and off input (ON1 and ON2),
which can interface directly with low-voltage control
signals. The TPS22976 is capable of thermal
shutdown when the junction temperature is above the
threshold, turning the switch off. The switch turns on
again when the junction temperature stabilizes to a
safe range. The TPS22976 also offers an optional
integrated 230-Ω on-chip load resistor for quick
output discharge when the switch is turned off.
The TPS22976 is available in a small, space-saving
3-mm × 2-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.
