What is TPS27S100ARRKR used for?
The TPS27S100ARRKR is deployed in industrial power distribution modules, motor driver supply switching circuits, and embedded system power sequencing boards where a 40 V, 4 A high-side switch with comprehensive fault protection is required. Automotive body control modules and 24 V industrial field I/O cards use it to protect loads against short-circuit and over-temperature events without discrete protection circuitry. USB port power management and hot-swap load controllers in rack-mount equipment also leverage its 80 mΩ low on-resistance and integrated current monitoring.

Frequently Asked Questions
What voltage and current ratings does TPS27S100ARRKR support, and how low is its on-resistance?
The TPS27S100ARRKR supports a maximum operating voltage of 40 V and a continuous load current of 4 A, with an on-resistance of 80 mΩ. At 4 A, the 80 mΩ resistance dissipates 1.28 W as heat, which is manageable within the 16-pin QFN thermal pad's rated thermal resistance, making it suitable for 24 V industrial bus switching with good efficiency.
Which built-in protection features does the TPS27S100ARRKR include to safeguard downstream loads?
The device integrates five protection mechanisms: under-voltage lockout, over-current limiting, short-circuit protection, thermal shutdown, and transient surge protection. These built-in features replace discrete protection networks that would otherwise require a fuse, thermistor, and transient suppressor, reducing component count by at least 3 to 5 parts and improving system reliability in automotive and industrial environments.
In a 24 V industrial I/O module, how does TPS27S100ARRKR compare to using a discrete MOSFET for high-side switching?
A discrete MOSFET solution for 40 V, 4 A high-side switching requires a gate driver IC, bootstrap circuitry, external gate resistors, and separate protection circuits, adding 5 or more components. The TPS27S100ARRKR integrates all of these functions in a single 16-pin QFN device at 80 mΩ, substantially reducing PCB area, simplifying design validation, and improving mean time between failures in harsh 24 V field environments.
Can TPS27S100ARRKR be used in automotive body control modules, and what qualification standard applies?
Yes, the TPS27S100ARRKR is suitable for automotive body control module applications. The device is designed to meet AEC-Q100 automotive qualification standards and operates across the extended automotive temperature range of -40°C to 125°C. Its 40 V rating provides margin above the 12 V to 24 V automotive bus, and the integrated transient protection handles load-dump events common in vehicle electrical environments.
