Texas Instruments TPS27081A High-Side Load Switch, SSOT-6

The Texas Instruments TPS27081A is a high-side power load switch designed for efficient power management in industrial and electronic applications. It features level shifting of the ON/OFF logic signal to VIN levels, allowing a low-voltage CPU or MCU logic (as low as 1V) to control higher voltage power supplies without the need for an external level shifter. The device supports a wide supply input range from 1.2V to 8V.

With integrated NMOS for PFET control and a low ON-resistance, high-current PFET, the TPS27081A delivers efficient power switching with minimal power loss. It provides full ESD protection on all pins, ensuring robust compatibility with other onboard components. The device also features ultralow leakage current in standby mode, typically 100nA, making it suitable for battery-powered applications.

The adjustable turn-on and turn-off slew rate control is achieved through external components (R1, R2, and C1), allowing designers to manage inrush current when switching large output capacitors. This flexibility makes the TPS27081A ideal for applications where controlled power sequencing is required.

This load switch is available in a compact SSOT-6 package and operates over a temperature range of -40°C to 85°C, ensuring reliable performance in demanding environments. Whether used in power management, industrial control, or portable devices, the TPS27081A offers a reliable and efficient solution for high-side load switching.
