 Hello, I'm Wojciech from ST Microelectronics application laboratory and I will focus on our smart galvanic isolated drivers in this presentation. Let's have a look at the agenda. First, we will briefly discuss the reason behind using galvanic isolation in digital output modules and give a short introduction to smart galvanic isolated drivers. In the main part of this presentation, we will introduce our 8-channel isolated drivers ISO-8200AQ and ISO-8200PQ and give an overview of its technical features. Last but not least, we will show the evaluation ecosystem and summarize the key benefits of these drivers. Auxiliary floor is not a very friendly environment in terms of electrical disturbance. This is due to operation of plenty of machines dealing with high amounts of electrical power. Strong electromagnetic fields, ground loops and other parasitic effects may disturb or even damage sensitive components like microprocessors or bus asics. Galvanic isolation is therefore an essential component to delimitate the disturbance occurring in the field from the low voltage and high speed digital ICs. It may be implemented either using a separate component, for example an octocoupler, or the galvanic isolation can be integrated inside the digital output device itself. This second option is definitely better as it saves both PCB space and design costs and it can be realized using our new ISO-8200AQ and ISO-8200PQ drivers. ISO-8200 is an 8-channel power switch integrating two isolated domains separated by a glass insulation layer. Communication between the two sides is realized using an electromagnetic transformer structure and RF-modulated data transfer. This architecture brings an outstanding performance in terms of noise immunity and data integrity. The IC is housed in a tiny QFN package and it comes in two options. ISO-8200AQ provides a 20 MHz SPI, while the ISO-8200PQ has a parallel digital interface. Each channel is controlled by a low RDS on MOSFET and it can supply an electric load up to 700 mA. Any combination of channels can also be connected in parallel in order to deliver a higher current. Active loads can be safely switched off without any external, pre-wheeling diodes by means of the integrated demagnetization circuit. ISO-8200 has a common diagnostic pin indicating over-temperature and the AQ version offers an additional per channel diagnostic information and power supply monitoring. The power stage is fully protected against overload or short circuit and the heating of the IC is limited using a two-level thermal shutdown protection. When it comes to switching capacity loads, the challenge for the power switch consists in high inrush currents that occur as a result of charging up the capacity at turn-on. During this initial phase, the power switch actively limits the current according to its protection specification. In case of ISO-8200, the current limitation level is typically 1.3 amps as reported in the datasheet of the device. It is commonly required for digital outputs to operate capacitances in range of tens of microfarads without any interruption that could be caused, for example, by a thermal protection triggering. The scope capture on the right side shows how the ISO-8200 charges up a 100 microfarad capacitor connected in parallel to the nominal 500 mA load. The charge up phase lasts approximately 4 milliseconds and the green waveform representing the load current shows that it's actively limited during this time. You can see on the magenta waveform how the output voltage is rising and it reaches the power supply level when the load is fully charged. If the IC operates in overload condition, for example, as a result of failure in load or short circuit, its power stage operates in linear mode in order to limit output currents. In such case, the thermal stress rapidly increases. Power drivers are designed to sustain such conditions by implementing what we call two-level thermal protection mechanism. As soon as the channel temperature reaches the junction shutdown threshold, the first level protection is triggered and the overheated channel is immediately switched off in order to cool down and keep its temperature within safe bounds. In case the overload condition lasts for a longer time, the IC substrate temperature keeps rising and the second level of protection may be activated. This is called case thermal protection and it is triggered when the temperature of the whole IC reaches approximately 130 degrees Celsius. At this point, all overloaded channels are instantly disabled until the IC temperature decreases sufficiently. ISO 8200 is provided with a complete evaluation tool set. It includes STM32 nuclear boards, ex-nuclear expansion shields and X-Cube firmware package supporting various development environments. One of the advantages of the nuclear platform is its modularity. The application can be simply extended by stacking up several expansion boards with the same or a different functionality. And of course, we provide quick start guides and user manuals for all the evaluation tools. Let's recap the key strengths of the ISO 8200. These devices integrate the leading edge galvanic isolation technology in a small form factor which allows to achieve high data integrity at very interesting costs. Two options of this IC are available, the AQ with SPI and the BQ with parallel interface. And last but not least, both products offer a high level of protection and diagnostics. Thanks for your attention.
