3 Description
The TPS22965x-Q1 is a small, ultralow-R_ON, single-
channel load switch with controlled turn on. The
device contains an N-channel MOSFET 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. The VOUT rise time is configurable so that inrush
current may be reduced. The TPS22965-Q1 and
TPS22965W-Q1 devices include a 225-Ω on-chip
load resistor for quick output discharge when the
switch is turned off.
The TPS22965x-Q1 devices are available in a small,
space-saving 2.00 mm × 2.00 mm 8-pin WSON
package (DSG) with integrated thermal pad allowing
for high power dissipation. The TPS22965-Q1 and
TPS22965N-Q1 devices are characterized for
operation over the free-air temperature range of
–40°C to 105°C. Furthermore, the TPS22965W-Q1
and TPS22965NW-Q1 devices feature wettable
flanks in the same SON package (DSG) and it is
characterized for operation over the free-air
temperature range of –40°C to 125°C.
