Includes galvanic isolation high-side switch product family
Equipped with a 20MHz SPI port that supports daisy-chaining.

STMicroelectronics released the ISO8200AQ, an 8-channel high-side galvanically isolated smart power switch, on the 8th.
The ISO8200AQ features a 20MHz SPI port that supports both per-channel temperature overload signal processing and efficient daisy-chaining of multiple devices, enhancing diagnostics and system management.

The Power-Good output allows you to check the status of the process-side power supply.

This device is part of ST's family of galvanically isolated high-side switches and provides optimal safety and robustness for demanding applications such as industrial PLCs, PCs, or peripherals, as well as numerically controlled machines used in conventional factory automation or Industry 4.0 smart factory scenarios.

Integrated galvanic isolation of 2500Vrms not only ensures excellent safety and saves space in the end application, but can also be used for additional general-purpose isolation.

The ISO8200AQ provides an SPI port that supports daisy chaining, so one hoseIt enables efficient control of multiple switches.

The PowerGood output sends an alarm to the control system when the power rail drops below a preset safety minimum threshold voltage and complements the fault output pin indicating communication errors or temperature overload conditions.

The ISO8200AQ manages all types of resistive, inductive, and capacitive loads with minimal power loss or heat dissipation through 8 channels with an on-resistance of 0.12Ω (average) and a maximum current rating of 0.7A.

The integrated protection function of ISO8200AQ further enhances safety against short circuits, channel temperature overloads, case temperature overloads, ground or supply protection losses, etc.

It is equipped with an output voltage control function that prevents damage caused by automatic restart and low voltage shutdown due to hysteresis, overvoltage protection by Vcc clamping, and switching off of inductive loads.

In addition, ISO8200AQ meets the IEC 61131-2 requirements regarding the functional attributes and characteristics of programmable controllers.

Users can achieve optimal performance in ISO8200AQ by leveraging the vast support tool ecosystem.

This includes the X-NUCLEO-OUT02A1 board, which allows for simple configuration evaluation and detailed adjustment, and the STSW-IFAPGUI graphical user interface, which supports the visualization of device operation.

The X-NUCLEO-OUT02A1 utilizes the IC's internal galvanic isolation between the logic and power stages and meets IEC61000-4-2, IEC61000-4-4, and IEC61000-4-5 to comply with industrial safety standards by adding EMC precautions and reverse polarity protection.

The ISO8200AQ is currently a 9 x 11mm 32-pin TFIt can be purchased in QFPN32 packages, and the price starts at $3,125 for orders of 1,000.
