SI86XXTISO-KIT

UG130: Si86xxT-EVB User's Guide The Si864xxT devices, the latest addition to the Si86xx isolator family, are 4-channel CMOS-based galvanic digital isolators surge rated at 10 kV. Operating up to 150 Mbps, they are available in wide body 16-pin SOIC packages and designed for the stringent isolation needs of the industrial, commercial, and automotive markets. Various channel configurations dictating the number of reverse channels and default output states are also available per the Si86xx data sheet’s ordering guide. The Si864xxT-EVB allows designers to quickly evaluate the Si8642ET’s capabilities and functionality, either by driving inputs to logic low via shunts, or injecting signals to the header pins via single wires or a 2x6 ribbon cable (not included). KEY POINTS • Discusses kit contents and equipment. • Describes hardware setup and demonstration. • Shows EVB schematic and layout. • Includes bill of materials and the ordering guide for Si864xxT-KIT.

Hardware Setup and Demonstration 3.1 Powering the Supplies Both sides of the Si8642ET isolator accept supplies between 2.5-5.5 V. See the figure below. Perform the following steps to set up the Si864xxT-EVB: • Remove all shunts. • Power Side-A. • Clip 5.0 V from the first power supply to TP1 (VDD1) and its GND to TP3 or TP5 (GND1). • LED, D1, will light up, confirming power is supplied. • Power Side-B. • Clip 5.0 V from the second power supply to TP2 (VDD2) and its GND to TP4 or TP6 (GND2). • LED, D2, will light up, confirming power is supplied. Figure 3.1. EVB — Powered Up 3.2 DC Signal Demonstration 3.2.1 Defaults The default output signal state of the Si8642ET is a logic High, meaning that with all shunts removed (EN1 and EN2 floating), all digital inputs (A1, A2, B3, B4) and all digital outputs will (B1, B2, A3, A4) will be at their respective High voltage level. These values can be measured and confirmed using the DMM. • Remove all shunts. • Measure with the DMM that all digital inputs (A1, A2, B3, B4) are logic High. • Measure with the DMM that all digital outputs (B1, B2, A3, A4) are logic High.

The SI8642ET will transmit this to the B-side, and the corresponding logic Low can be observed and measured with the DMM on J2, B2. • Place a shunt across J2 at B3. • This produces a logic Low input on reverse channel B3. The SI8642ET will transmit this to the A-side, and the corresponding logic Low can be measured with the DMM on J1, A3. Figure 3.3.

The SI8642ET will transmit this to the B-side, and the corresponding logic Low can be observed and measured with the DMM on J2, B2. • Place a shunt across J2 at EN2. • This drives EN2 to a logic Low input which tri-states outputs B1 and B2. A Hi-Z output can be observed on outputs B1 and B2 with the DMM (appearing as a high), even while A1 is a logic Low and A2 is a logic High. Figure 3.4.
