TLE9471ESXUMA1

Overview

The TLE9471ES is a System Basis Chip (SBC) from Infineon's Lite SBC family, designed for automotive applications. It integrates a 5 V/500 mA low-drop buck DC/DC voltage regulator for main supply and a 5 V/100 mA linear voltage regulator with off-board protection. The device features a high-speed CAN transceiver supporting FD communication up to 5 Mbit/s per ISO 11898-2:2016. It includes a charge pump output for reverse polarity protection, a universal high-voltage wake input, and a configurable GPIO. The chip operates within a wide input voltage range and supports low-power modes with cyclic wake capabilities.

Feature Summary

• Integrates a 5 V/500 mA Buck SMPS and a 5 V/100 mA LDO
• High-Speed CAN FD transceiver supporting up to 5 Mbit/s
• Charge pump output for N-channel MOSFET reverse polarity protection
• Configurable timeout/window watchdog and fail-safe signalization

Applications

• In-Cabin Wireless Charger
• Transmission and Transfer Case modules
• Water pump and Wiper ECU
• HVAC ECU and Control panel
• Light Control Unit (LCU)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the package marking matches the required identification for the production batch. Ensure the component grade meets the specified automotive qualification standards before integration into the final design.

Selection Notes

Select this variant when a 500 mA main supply current is required for the microcontroller. The integrated spread spectrum modulation in the DC/DC converter optimizes EMC performance. Ensure the application utilizes the CAN FD capability up to 5 Mbit/s and requires the specific pinout of the PG-TSDSO-24-1 package.

Part Context

This component belongs to the OPTIREG™ Lite SBC family, which offers scalable system basis chips for automotive networks. It maintains hardware and software compatibility with other families such as TLE926x and TLE927x. The device shares the same PG-TSDSO-24-1 package footprint across the family variants.
