Product overview
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.
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).
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.
The PSI5 interface allows either point to point connection or bussed mode.
