High-Side Load Switch offers level shift and slew-rate control.
Press Release Summary:
Integrating power PFET and control NFET in 6-pin SOT-23 package measuring 2.9 x 1.6 x 0.75 mm, Model TPS27081A supports supply voltage range of 1.0–8 V. Supply inputs are fully protected against ESD strikes on all pins, and high-pulsed current rating allows reliability under short-circuit conditions. Replacing discrete FET switches, Model TPS27081A is suited for any application that requires load switching or power sequencing, including notebooks, tablets, LCD TVs, GPS systems, and set-top boxes.
Original Press Release:
TI Introduces Most Flexible PFET High-side Load Switch with Level Shift and Slew-rate Control
Power switch offers the widest voltage range to replace discrete FET switches
DALLAS, -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today 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 1.0 V up to 8 V, 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.

Key features and benefits of the TPS27081A
--Â 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.
--Â Higher reliability in the system: Supply inputs are fully protected against ESD strikes on all pins, thus providing better ESD compatibility with other on-board components than the competition.
--Â Ensures high efficiency: Low ON resistance with the high-current PFET ensures low voltage drop across the PMOS transistor.
--Â Higher Reliability: High-pulsed current rating allows reliability under short-circuit conditions, which ensures longer product lifetimes.
--Â Broad power switch portfolio: The TPS27081A complements TI's low ON-resistance integrated load switches, such as the TPS22965 and the TPS22929D.
Availability, packaging and pricing
The TPS27081A is available in a 2.9-mm x 1.6-mm x 0.75-mm thin SOT-23 (DDC) package. Suggested retail pricing in 1000-unit quantities is US$0.12.
