Application note

AU5790 Single wire CAN transceiver

AN2005

1. INTRODUCTION

The AU5790 single wire CAN transceiver is a line transceiver intended primarily for in-vehicle class B multiplexing applications. This device

provides interfacing between a CAN data link controller and a single wire physical bus system with ground return.

This application note is intended to explain AU5790 functions and benefits, and to guide the user in applying the AU5790 in a vehicle network

environment.

2. OVERVIEW

2.1 CAN

The Controller Area Network (CAN) is a serial communication protocol widely used in Automotive and Industrial applications for interconnecting

control units, sensors, actuators, etc.

There are two relevant CAN message formats in use today. One is the standard message format which is defined in CAN Specification 1.2. The

other one is the extended message format which is described in CAN Specification 2.0 Part B.

Primarily the two differ in that the standard message frame has 11 identifier bits, where the extended frame has 29 identifier bits.

2.1.1 Bit Timing and Propagation Delay

By the CAN bit timing definition, the Nominal Bit Time (NBT), with time duration t consists of three non-overlapping segments: SYNC_SEG,

bit,

TSEG1, and TSEG2, with time duration t

and t

respectively, as shown in Figure 2. Each of these segments may be

SYNC_SEG, seg1,

seg2,

programmed to be an integral number of the Time Quantum (TQ), whose time duration, t is derived from the oscillator. The sample point

usually is located at the end of TSEG1.
