Introduction

ISL8485EMPZ is a high performance 4-channel CAN transceiver that combines a transmitter, receiver, driver and receiver in a single package. It is designed to meet the physical layer requirements of the CAN 2.0 A, B and the ISO-11898-2 standard. It offers excellent interference rejection ratio, wide operating temperature range and good EMC performance. In addition, the ISL8485EMPZ is capable of withstanding high voltage transients that are common in hostile automotive and industrial environments.

Application Field

The ISL8485EMPZ is suitable for a wide range of applications such as automotive, industrial, medical and consumer electronics. Automotive applications include in-vehicle communication and control systems, including engine management and brake control. Industrial applications range from factory automation to process control. The device is also used for medical monitoring and diagnostic systems, and for consumer electronics including remote control and wireless home networking.

Working Principle

The ISL8485EMPZ is a high performance bi-directional transceiver, which is composed of four independent channels. When enabled by an external control signal, each channel can be used either as a driver, to transmit data onto the CAN bus, or as a receiver, to receive data from the CAN bus.Each channel consists of two differential driver stages, capable of transmitting high speed differential voltages onto the CAN bus with high accuracy. The transmitted signal is received by a differential amplifier with a sensitivity specified in the ISO-11898 standard. The output signal is then sent to the receive logic, which is designed to detect and reconstruct the signal in the presence of noise, according to the parameters set in the receive logic.The ISL8485EMPZ is equipped with transceiver accuracy control, allowing the receiver to be calibrated for improved signal integrity. This is of particular importance when transmitting/receiving data in noisy environments.

Conclusion

The ISL8485EMPZ is a high-performance CAN transceiver with 4 independent channels, suitable for a wide range of applications. It combines a transmitter, receiver, driver and receiver into a single package, allowing for compact designs and improved signal integrity. By using the transceiver accuracy control feature, the receiver can be calibrated for improved signal integrity in noisy environments.
