Bi-directional Remote Sensor Unit Interface

Features and Benefits

ꢀ

Two identical interface channels for remote sensor units

Two connection modes: connection to OUTx and RETx or connection to OUTx and GND

ꢀ

16 bit Standard SPI for control and diagnosis via a microcontroller

Supply voltage for each remote unit with a supply current up to 45mA

Current limitation with an analog feed back loop for each channel

Receive data from the remote unit by current modulation with a transmission rate of

10kHz

ꢀ

Transmission of data to the remote unit via PWM voltage pulses

Data input/output can be directly connected to a microcontroller input/output (CMOS)

Low current consumption

All pins to the external interface are short-circuit and high-voltage protected

High immunity against cross coupling between the two channels

The current modulation provides high noise immunity for data transfer

Application

ꢀ

Remote automotive sensors (between ECU and sensors).

1. Functional Diagram

2. Description

This interface IC is designed for remote

automotive sensors, especially between a

main ECU and remote (sensor) units. It

contains two identical interfaces and the

main task of each interface is to supply one

remote unit and to receive digital information

from the same remote unit. It is also

possible to send data as PWM voltage

pulses to the remote unit, for example to

program the remote unit for its special

application. This is done by one active wire:

the interface supplies the external unit with

a pre-regulated voltage, the external unit

transmits the digital information back to the

interface by current modulation. A
