TITCAN2451RHBRQ1
Overview
The TCAN2451RHBRQ1 is an AEC-Q100 qualified CAN FD System Basis Chip (SBC) featuring an integrated CAN transceiver and a high-efficiency buck regulator. It supports data rates up to 8Mbps and provides a wide input voltage range from 5.5V to 28V, making it suitable for automotive and industrial battery-powered systems. The device includes integrated high-side switches and multiple wake-up options to minimize power consumption in standby and sleep modes.
Why Choose This Part
This SBC simplifies PCB design by integrating a 1A buck regulator with selectable 3.3V or 5V output and a secondary 200mA LDO for off-board sensors. It features integrated spread spectrum modulation to reduce electromagnetic interference and supports selective wake-up (partial networking) to significantly reduce total system current draw.
Applications
Key Specifications
Getting Started
Designers should select the target output voltage via the VSEL pin and choose an inductor compatible with the 1.8MHz to 2.4MHz switching frequency. Evaluation can be performed using TI's CAN FD development tools, ensuring the VCC1 and VCC2 capacitors are placed close to the pins for stability. Refer to the TCAN245x-Q1 family documentation for configuring the WAKE pins and cyclic sensing logic.
