Galvanically isolated, 8-channel high-side power switches
designed for robust, reliable smart factory automation
High-end features and galvanic isolation
The galvanically isolated line of ST intelligent power switches combine process and control logic stages in one 8-channel, high-side switch, with two independent voltage domains able to communicate through galvanically isolated channels. Embedding a flexible SPI or parallel control interface, this new series helps reduce BOMs and PCB space, and improve reliability in factory automation applications.
Available in QFN 9x11 or PowerSO-36 packages with 0.7 A or 1 A per channel, plus dedicated evaluation boards tailored to each package, intuitive GUIs, and software to simplify your design.

Simplified control, reliable power
Simplified control, reliable power
The parallel interface series offers octal high-side switches for designs requiring robust galvanic isolation with easy and direct control. The ISO808 is a scalable solution able to drive loads up to 0.7 A, while the ISO808-1 offers higher power driving up to 1 A.
Advanced control and diagnostics
Advanced control and diagnostics
The SPI interface series integrates galvanic isolation and enhanced control and diagnostics. Featuring an SPI interface, the ISO808A for up to 0.7 A loads and the ISO808A-1 for up to 1 A loads offer higher functionality and more advanced diagnostics. The ISO8200AQ allows diagnostics on each channnel.
