TIISO1042BQDWQ1
Overview
The ISO1042BQDWQ1 is a galvanically-isolated CAN FD transceiver designed for automotive applications and harsh industrial environments. It supports data rates up to 5Mbps and provides reinforced isolation with 5000-VRMS protection per UL 1577. The device features a wide common-mode voltage range of +/-30V and is AEC-Q100 qualified for use in vehicle networking.
Why Choose This Part
The component offers robust protection with a +/-70V DC bus fault rating and high common-mode transient immunity (CMTI) of 100 kV/us. It integrates undervoltage protection and a dominant time-out (DTO) feature to prevent bus blocking. Its wide supply range on the controller side (1.71V to 5.5V) allows for direct interfacing with low-voltage FPGAs and microcontrollers without level shifters.
Applications
Key Specifications
Getting Started
To evaluate this transceiver, use the ISO1042DWEVM evaluation module which allows for easy probing of all pins. Ensure that the VCC1 side is powered by the controller supply (1.71V-5.5V) and VCC2 is powered by the 5V bus-side supply. Proper PCB layout is critical; maintain clear creepage and clearance distances under the 16-SOIC package to preserve isolation ratings.
