Texas Instruments (TI) has
introduced a high-side load
switch that integrates a power
PFET and a control NFET in a tiny 6-
pin package. Offering support for
the industry's widest supply
voltage range at 1.0V up to
8V, the TPS27081A is the
most flexible replacement
for discrete FET switches.
The load switch also offers
adjustable slew-rate control so
designers can implement the device
in any application that requires load
switching or power sequencing,
including notebooks, tablets, LCD
televisions, global positioning
systems (GPS) and set-top boxes.
TPS27081A offers better
flexibility; higher voltage range of
operation for both the on/off
function and input/output
voltages supports wider
range of applications with
lower bill-of-materials cost.
The switch also brings
higher reliability to the system
given that supply inputs are fully
protected against ESD strikes on all
pins, thus providing better ESD
compatibility with other on-board
components than the competition.
