The TPS274C65xS device is a quad-channel smart high-side switch with a serial interface (SPI) control and is designed to meet the requirements of industrial control systems. The low 72mΩ RDSON minimizes device power dissipation even when providing large output load current. The device integrates protection and diagnostic features to ensure system protection even during harmful events like short circuits or load failures. The device protects against faults through a reliable current limit which is adjustable from 250mA to 2.45A to provide protection regardless of output load current. The TPS274C65xS has a configurable inrush current period which sets a higher current limit during turn-on for high inrush current loads, charging capacitive loads faster, or driving incandescent bulbs.

The TPS274C65xS also provides accurate current sense and an integrated analog to digital converter (AS) that allows for improved load diagnostics. By reporting load current digitally, the device allows for communication over any isolation barrier while enabling predictive maintenance and load diagnostics to improve system lifetime. Additional diagnostic features are integrated, such as on-state or off-state open load detection and short-to-supply detection.

The TPS274C65xS is available in a small 6mm × 6mm VQFN package with 0.5mm pin pitch, which minimizes design PCB footprint.
