Description

The STEVAL-IFP07V1 demonstration board is an application intended to allow designers to

evaluate the behavior of the SCLT3-8BT8 device in industrial environmental conditions. The

board accommodates two SCLT3-8BT8 chips connected to the SPI bus in a daisy chain

configuration. It offers a 16-bit digital input interface and indicates each sensor logic state

with an LED.

Features

■ 8/16 input channel topology (SCLT3-8BT8 chip / STEVAL-IFP007V1 board)

■ Fully integrated current limiter

■ Termination for IEC 61131-2 type 1 and 3 inputs

■ Digital filter on each input

■ SPI communication peripheral

■ Voltage regulator integrated on the chip

■ Thermal alarm

■ Wide range supply voltage operation

Benefits

■ Low power dissipation compared to discrete solutions

■ Small external component count

■ Overvoltage protection

■ ESD in accordance with IEC 61000-4-2, class 3, 8 kV air discharge, 6 kV contact

discharge

■ Excellent EMC immunity

– High energy surge (IEC 61000-4-5), 2 kV / criteria “B” (42

Ω / 0.5 µF) without any

Transil

™ protection

– Fast transient burst (IEC 61000-4-4), +4 kV / –8 kV (±8 kV(a)) / criteria “A”

– RF amplitude modulation (IEC 61000-4-6), 150 kHz - 80 MHz, 10 V / criteria “A”

■ Cost-effective isolation thanks to an SPI bus

■ Reduces overall dissipation

■ Compact module HTSSOP-38 package

With 10 pF capacitive GND coupling (primary vs. secondary ground of the isolation).
