3 Description
The TPS22975 product family consists of two
devices: TPS22975 and TPS22975N. Each device is
a single-channel load switch that provides a
configurable rise time to minimize inrush current. The
device contains an N-channel MOSFET 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. The switch is controlled by an on and off input
(ON), which is capable of interfacing directly with low-
voltage control signals. TPS22975 has an optional
230-Ω on-chip load resistor for quick output discharge
when switch is turned off.
The TPS22975 is available in a small, space-saving
2-mm × 2-mm 8-pin SON package (DSG) 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.
