CIE Components in Electronics
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 1.0 V up to 8 V, the TPS27081A is said to be 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 of the TPS27081A include: greater flexibility, a higher voltage range of operation for both the on/off function and input/output voltages supports a 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, providing better ESD compatibility with other on-board components than the competition; ensures high efficiency, a low ON resistance with the high-current PFET ensures low voltage drop across the PMOS transistor and higher reliability, a high-pulsed current rating allows reliability under short-circuit conditions, which ensures longer product lifetimes.
