Introduction

AI Translation

The ISO1044B device is an electrically isolated Controller Area Network (CAN) transceiver that complies with the ISO11898-2 (2016) standard specifications. It provides a DC bus fault protection voltage of ±58V and a common-mode voltage range of ±12V. In CAN FD mode, it supports a maximum data rate of 5Mbps, enabling faster payload transmission compared to classic CAN. It uses a silicon dioxide (SiO₂) insulation barrier, which can withstand a voltage of 3000VRMS and an operating voltage of 450VRMS. The electromagnetic compatibility is significantly enhanced, enabling system-level ESD, EFT, and surge protection and complying with radiation standards. When used with an isolated power supply, it can withstand high-voltage surges and prevent bus noise current from entering the local ground. It supports a wide ambient temperature range from –40°C to +125°C. It is available in a small SOIC-8 (D) package, which can significantly reduce the solution size compared to the traditional method of using optocoupler-isolated CAN transceivers.
