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
