STMicroelectronics launch galvanically isolated high-side switches

New Products

▤ Summary

The 8-channel switches, ISO808, ISO808A, ISO808-1, and ISO808A-1, drive all types of industrial loads - capacitive, resistive, and inductive - with one side connected to ground. The ISO808 and ISO808-1 provide a separate input pin for each channel and allow either direct control or synchronous operation driving all outputs simultaneously. Internal logic reports any data errors and a watchdog ensures the process-stage outputs are safe if the control-side supply voltage is missing. While pin-compatible with other popular switches, STs ISO808 family delivers the extra benefits of lower RDS(on) and the power-good pin of the SPI-input variants. Four X-NUCLEO industrial digital-output expansion cards (X-NUCLEO-OUT11A1, -OUT12A1, -OUT13A1, and -OUT14A1) for STM32 Nucleo development boards accelerate evaluation, while the graphical application, STSW-IFAPGUI, eases configuration and control.
