STEVAL-IFP010V3: designing with VNI2140J dual high-side
smart power solid-state relay IC
Introduction
The STEVAL-IFP010V3 demonstration board has been developed to show the VNI2140J
device functionalities within industrial applications such as PLCs (programmable logic
controllers) which drive lamps, valves, relays, and similar loads.
This tool allows evaluating VNI2140J features, in particular embedded self-protection,
power-handling capabilities, operation and diagnostic feedback, thermal behavior and
conformity to EMC immunity standards.

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:
● Two output channels (2 x 1 A)
● Two input channels
● Two feedback channels for fault and open load diagnostics
● Bidirectional opto-isolated interface for MCU safe connection
● TTL/CMOS compatible signals for MCU direct connection
● LEDs to indicate outputs
● Compliance to IEC61000-4-4 and IEC61000-4-5 standards
● Compatibility with existing STMicroelectronics tools (IBU communication board,
CANIC10, for example) 10.5 V to 36 V DC power supply voltage range demonstration
