Bangalore: Texas Instruments Incorporated 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 that 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.

According to TI, TPS27081A offers many key features and benefits, including better flexibility which allows higher voltage range of operation for both the on/off function and input/output voltages and supports wider range of applications with lower bill-of-materials cost.

The switch is said to offer higher reliability in the system by protecting the supply inputs against ESD strikes on all pins, thus providing better ESD compatibility with other on-board components. It also ensures high efficiency by the low ON resistance with the high-current PFET, thereby ensuring low voltage drop across the PMOS transistor.

The switch also guarantees to provide longer product lifetimes as the high-pulsed current rating allows reliability under short-circuit conditions.

The TPS27081A complements TI’s low ON-resistance integrated load switches, such as the TPS22965 and the TPS22929D.
