TLE9461ESV33XUMA1

Overview

The TLE9461ESV33XUMA1 is a monolithically integrated System Basis Chip (SBC) from Infineon's Lite SBC family, designed for automotive CAN applications. It provides main supply for microcontrollers and interfaces with the CAN bus network. Key electrical parameters include a 3.3 V low-dropout linear voltage regulator (LDO) capable of 150 mA output (250 mA peak), a secondary 5 V LDO with 100 mA output, and a High-Speed CAN transceiver supporting FD communication up to 5 Mbit/s per ISO 11898-2:2016. The device operates within a wide input voltage range of 4.75 V to 28 V and features an exposed pad PG-TSDSO-24-1 package.

Feature Summary

• Integrated 3.3 V LDO (150 mA) and 5 V LDO (100 mA) for system power management
• High-Speed CAN FD transceiver supporting data rates up to 5 Mbit/s
• Configurable wake-up sources including Cyclic Wake, CAN bus messages, and high-voltage inputs
• Comprehensive supervision functions including window watchdog, thermal shutdown, and undervoltage detection

Applications

• HVAC ECU and Control panel
• Light Control Unit (LCU) for front, rear, and ambient lighting
• Seat control module and seat belt pretensioner systems
• Steering column and steering lock modules
• Closure modules such as trunk and sliding door controllers

Procurement Notes

Verify the component against the official Infineon datasheet Rev. 1.2 to confirm pin assignments and electrical characteristics. Ensure the ordering suffix XUMA1 corresponds to the required tape and reel packaging format. Confirm AEC-Q100 qualification status for automotive deployment requirements.

Selection Notes

Select this variant when a 3.3 V main regulator output is required for the microcontroller supply. Compare against the TLE94613ESV33XUMA1 if CAN Partial Networking functionality is needed. Ensure the application utilizes the PG-TSDSO-24-1 package footprint and accounts for the exposed pad thermal connection requirements.

Part Context

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