Overview

The TCAN332DR is a 3.3V CAN transceiver designed to operate at data rates up to 1Mbps. It provides an interface between a CAN protocol controller and the physical bus, offering a wide common mode range of +/-12V and integrated protection features for harsh environments.

Why Choose This Part

The TCAN332DR operates from a single 3V to 3.6V supply, eliminating the need for 5V rails in modern low-power designs. It features extensive protection including TXD/RXD dominant time out (DTO) to prevent bus blocking and thermal shutdown to protect the device under fault conditions.

Applications

Industrial Automation
Used in factory control systems requiring 3.3V logic levels and robust differential signaling over long cable runs.
Building Automation
Ideal for HVAC and lighting control networks where a single 3.3V supply simplifies the power distribution architecture.
Vehicle Diagnostics
Suitable for interface tools that bridge vehicle CAN networks with low-voltage microcontroller systems.

Getting Started

To evaluate this part, connect the TXD and RXD pins to your 3.3V microcontroller CAN controller and terminate the CANH/CANL bus with 120-ohm resistors. Ensure the VCC pin is decoupled with a capacitor as close to the 8-SOIC package as possible to maintain signal integrity at 1Mbps.
