3 Description

The ISO1044B device is a galvanically-isolated

controller area network (CAN) transceiver that meets

the specifications of the ISO11898-2 (2016) standard.

The ISO1044B device offers ±58-V DC bus fault

protection and ±12-V common-mode voltage range.

The device supports up to 5-Mbps data rate in CAN

FD mode allowing much faster transfer of payload

compared to classic CAN. This device uses a silicon

dioxide (SiO2) insulation barrier with a withstand

voltage of 3000 VRMS and a working voltage of 450

VRMS. Electromagnetic compatibility has been

significantly enhanced to enable system-level ESD,

EFT, surge, and emissions compliance. Used in

conjunction with isolated power supplies, the device

protects against high voltage, and prevents noise

currents from the bus from entering the local ground.

The ISO1044B device supports a wide ambient

temperature range of –40°C to +125°C. The device is

available in the small SOIC-8 (D) package which

significantly reduces the solution size compared to a

traditional approach using optocouplers to isolate the

CAN transceiver.
