The TPS274C65 device is a quad channel 72-mΩ smart high-side switch intended for use for output ports with protection for 24-V industrial systems. The device is designed to drive a variety of resistive, inductive and capacitive loads. The device integrates various protection features including overload protection through current limiting, thermal protection, short-circuit protection, and reverse current protection. For more details on the protection features, refer to the Feature Description and Application Information sections of the document.

In addition, the device diagnostics features include a digital per-channel readout of output current, output voltage and FET temperature. The high-accuracy load current sense allows for integration of load measurement features that can enable predictive maintenance for the system by watching for leading indicators of load failures. The device also integrates open load detection in on and off states to enable protection against wire breaks. In addition, the device includes an open drain FLT pin output that indicates device fault states such as short to GND, short to supply, overtemperature, and the other fault states discussed.
