STEVAL-IFP019V1: design with VNI4140K-32 quad high-side
smart power solid-state relay ICs
Introduction
The STEVAL-IFP019V1 demonstration board has been developed to show the new
VNI4140K-32 device functionalities within industrial applications such as PLCs
(programmable logic controllers) which drive lamps, valves, relays, and similar loads.
This tool allows the evaluation of the VNI4140K-32 features, in particular all kinds of
embedded self-protections, power-handling capabilities, operation and diagnostic feedback,
thermal behavior, and conformity to inherent IEC standards.

A double-sided PCB allows the obtaining of 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 1 A)
■ Four input channels
■ Four feedback channels for diagnostic purposes
■ Bi-directional 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, IEC61000-4-5, and IEC61000-4-2
■ 10.5 V to 36 V DC power supply voltage range.
