Description

The Peripheral Sensor Interface (PSI5) is an

interface for automotive sensor applications. PSI5

is an open standard based on existing sensor

interfaces for peripheral sensors and offers a

universal and flexible solution for multiple sensor

applications.

Features

 2-channel PSI5 transceiver compatible with

The PSI5 interface allows asynchronous or

synchronous operations and different bus modes.

The device is compatible with both v1.3 and v2.1

PSI5 revisions (limitations are specified inside this

document). It operates with a wide range of

sensor supply current and variable data word

length (8 to 28 bit).

rev. 1.3 and rev. 2.1

 Manchester coded digital data transmission

 High data transmission speed of 125 kbps

(optional 83.3 kbps and 189 kbps)

 High EMC robustness and low emission

 Bootstrap circuits for sync pulses

The sensors are connected to the ECU using the

same line for power supply and data

transmission. The transceiver IC provides a pre-

regulated voltage to the sensors and reads in the

transmitted sensor data.

 Current limitation and voltage clamp on

interface pins

 Integrated charge pump stage for pre-

regulation with spread spectrum approach

 Integrated FLL module for high accuracy timing

The PSI5 interface allows either point to point

connection or bussed mode.

control

 Reverse voltage protection structure
