TLE94613ESXUMA1

Overview

The TLE94613ESXUMA1 is an automotive-grade System Basis Chip (SBC) from Infineon's OPTIREG Lite SBC family, housed in a PG-TSDSO-24-1 package. It integrates a high-speed CAN transceiver supporting FD communication up to 5 Mbit/s and CAN Partial Networking. The device provides two low-dropout linear voltage regulators: VCC1 at 5 V/150 mA for the microcontroller and VCC2 at 5 V/100 mA with short-to-battery protection. Key features include a configurable timeout/window watchdog, a charge pump output for reverse polarity protection, and extensive diagnostic capabilities via SPI.

Feature Summary

• High-Speed CAN Transceiver: Supports ISO 11898-2:2016, CAN FD up to 5 Mbit/s, and CAN Partial Networking.
• Dual Voltage Regulators: 5 V LDO (150 mA main supply) and 5 V LDO (100 mA sensor supply with off-board protection).
• Low-Power Modes: Features Stop and Sleep modes with periodic cyclic wake and sense capabilities.
• Integrated Protection: Includes overtemperature protection, short circuit diagnostics, and a charge pump for N-channel MOSFET reverse polarity protection.

Applications

• HVAC ECU and Control Panel
• Light Control Unit (LCU)
• Seat Control Module
• Steering Column and Steering Lock

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm pin compatibility and feature set. Ensure the component meets AEC-Q100 qualification requirements for the target automotive application environment.

Selection Notes

Select this variant for applications requiring CAN FD support and partial networking functionality. Compare quiescent current specifications in Stop and Sleep modes against system power budget requirements. Confirm that the 150 mA regulator output is sufficient for the connected microcontroller load.

Part Context

This component belongs to the scalable OPTIREG Lite SBC family. It shares hardware and software compatibility with other variants in the series, such as the TLE9461 and TLE9471, allowing for design flexibility across different product generations within the same package footprint.

Replacement Considerations

Direct replacements within the same family include TLE9461ESV33XUMA1 and TLE9471-3ES. Verify that the alternative part number matches the required output voltage (5 V vs 3.3 V) and current ratings before substitution.
