Overview

The TCAN28473RHBRQ1 is an automotive-qualified System Basis Chip (SBC) that integrates high-speed CAN FD and LIN physical layers with comprehensive power management. It simplifies ECU design by providing up to three voltage regulators and four high-side switches in a single 32-pin VQFN package with wettable flanks for improved optical inspection.

Why Choose This Part

The device reduces PCB footprint and complexity by consolidating CAN, LIN, and multiple LDOs into one IC. Its AEC-Q100 qualification and wide 5.5V to 28V supply range ensure reliability in harsh automotive electrical environments.

Applications

Automotive Body Electronics
Ideal for central gateway modules and body control units requiring coordinated CAN FD and LIN communication with integrated power rails.
Functional Safety Systems
Designed for Quality-Managed functional safety applications, providing diagnostics and protection features for critical vehicle subsystems.
Low-Power Remote Nodes
Suited for modules that must minimize battery drain, utilizing a 35uA sleep mode and multiple wake-up sources.
Power-Distributed Gateways
Uses its four integrated 150mA high-side switches to control local loads or sensors without external MOSFETs.
