ST’s intelligent high-side switches and drivers provide one or more channel bipolar/MOSFET output switches to drive inductive, capacitive or resistive loads. Diagnostics for CPU feedback and extensive use of electrical protection features make these devices inherently indestructible and suitable for industrial applications. These devices operate over a wide range of voltages: from +5.5 up to +50 V.
Galvanic isolated high-side smart power switch with SPI features rich diagnostic, safety, and protection features
The galvanic isolated octal high-side smart power switch enhances diagnostics and system management by providing a 20 MHz SPI port allowing both per-channel over-temperature signalization and efficient daisy-chaining of multiple devices. A power-good output indicates the status of the process-side power supply.
The device enlarges ST’s family of galvanic isolated high-side switches, featuring maximum safety and robustness in demanding applications such as industrial PLCs, PCs, or peripherals, and numeric-control machines in conventional factory automation or Industry 4.0 smart-factory scenarios.
