The TLE9471ESV33XUMA1 is a Lite CAN System Basis Chip (SBC) from Infineon Technologies, designed to serve as both a power supply and a CAN bus interface for automotive microcontrollers.
It's well-suited for engineers designing body control, powertrain, or comfort electronics who need a single device to handle voltage regulation, CAN FD communication, and system monitoring without adding extra parts to the board.
This part belongs to Infineon's Lite SBC family, which shares a common PG-TSDSO-24-1 exposed pad package and full hardware and software compatibility across variants.
Here's what makes the part stand out:
Key Features of the TLE9471ESV33XUMA1
3.3 V Buck DC/DC Voltage Regulator
The integrated step-down converter supplies up to 500 mA at 3.3 V with built-in spread-spectrum modulation, providing clean, EMC-friendly power to the main microcontroller.
High-Speed CAN FD Transceiver
Supports CAN FD communication up to 5 Mbit/s in line with ISO 11898-2:2016 and SAE J2284, so it handles both classic CAN and higher-speed data without a separate transceiver.
Exposed Pad PG-TSDSO-24-1 Package
The 24-pin package includes an exposed die pad for improved thermal dissipation, and it's designed for standard surface-mount PCB assembly.
Configurable Wake and Low-Power Modes
Cyclic Sense, Cyclic Wake, and CAN wake-up sources allow the device to remain in Stop or Sleep mode, drawing microamp-level current until it's needed, which is important for always-on automotive nodes.
Watchdog, Reset, and Fail-Safe Supervision
A configurable timeout and window watchdog, dedicated reset and interrupt outputs, and a fail-safe mode give the system a defined way to recover from faults.
AEC-Qualified and RoHS Compliant
Validated to AEC-Q100/101 for automotive use and manufactured as a Green Product, so it's PB-free and ready to drop into compliant designs.
