TPS27081A - TI introduces most flexible PFET high-side load switch with level shift and slew-rate control
News Release from:
04 October 2012
Texas Instruments 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 and set-top boxes.
Key features and benefits of the TPS27081A
-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.
-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.
-Ensures high efficiency: Low ON resistance with the high-current PFET ensures low voltage drop across the PMOS transistor.
-Higher Reliability: High-pulsed current rating allows reliability under short-circuit conditions, which ensures longer product lifetimes.
-Broad power switch portfolio: The TPS27081A complements TI's low ON-resistance integrated load switches, such as the TPS22965 and the TPS22929D.
