The L6362A from STMicroelectronics is an IO-Link transceiver for three-wire connections which can operate in the COM1 mode at 4.8kbaud, the COM2 mode at 38.4kbaud and the COM3 mode at 230.4kbaud.

The L6362A is primarily intended to provide connections to sensors in industrial systems operating from a 24V power bus. The host device that needs the connection to a sensor is typically a programmable logic controller, an IO-Link master, a relay or a valve.

The L6362A offers a rich set of functions to protect the circuit in the event of faults. It can protect against reverse polarity, output short-circuits and over-voltage events. It can also withstand fast transients of up to ±1kV.

The L6362A’s output stage can be configured as high-side, low- side or push-pull, and it can drive resistive, capacitive and inductive loads.

FEATURES

  • Supply-voltage range: 7V to 36V
  • 5V- and 3.3V-compatible I/Os
  • Linear regulator with selectable 5V or 3.3V output
  • Fast demagnetisation of inductive loads
  • Operating-temperature range:
    -40°C to 125°C

APPLICATIONS

  • Industrial sensors
  • Factory automation
  • Process control

The STEVAL-IFP017V3 is an evaluation board designed to enable the analysis of the features of the L6362A including fast demagnetisation and reverse polarity overload over-temperature ground and supply open-wire protection functions.

On the STEVAL-IFP017V3 the exposed pad of the L6362A is connected to an electrically floating copper area which acts as a heat-sink.

Orderable Part Number: STEVAL-IFP017V3
