AN2684 Application note STEVAL-IFP006V1: designing with VNI4140K quad high-side smart power solid-state relay ICs Introduction The STEVAL-IFP006V1 demonstration board has been developed to show the new VNI4140K device functionalities within industrial applications such as PLCs (programmable logic controllers) which drive lamps, valves, relays, and similar loads. This tool allows evaluating VNI4140K features, in particular all kinds of embedded self- protections, power-handling capabilities, operation and diagnostic feedback, thermal behavior and conformity to inherent IEC standards. Figure 1. STEVAL-IFP006V1 A double-sided PCB allows obtaining the best trade-off between a routing solution and thermal management results. The main features of the demonstration board are: Four output channels (4 x 0.7 A) Four input channels Four feedback channels for diagnostic purposes Bidirectional opto-isolated interface for MCU safe connection TTL/CMOS compatible signals for MCU direct connection LEDs to indicate output state Compliance to IEC61000-4-4 and IEC61000-4-5 Compatibility with existing STMicroelectronics tools (IBU communication board, CANIC10) 10.5 V to 36 V DC power supply voltage range May 2009 Doc ID 14266 Rev 1 1/21 www.st.com Contents AN2684 Contents 1 Electrical characteristics . 4 2 Safety precautions 5 3 VNI4140K quad high-side smart power solid-state relay IC description . 6 4 IFP006V1 demonstration board description 8 4.1 Overview 8 4.2 IFP006V1 schematic . 9 4.3 IFP006V1 connectors 10 4.4 IFP006V1 thermal management . 11 4.5 EMC immunity test 12 4.5.1 Description . 12 4.5.2 Test conditions 12 4.5.3 Burst immunity test 13 4.5.4 Surge test . 14 Appendix A Bill of material 16 Appendix B PCB layout . 18 Appendix C References . 19 Revision history 20 2/21 Doc ID 14266 Rev 1
