TLE94613ESV33XUMA1

Overview

The TLE94613ESV33XUMA1 is an automotive System Basis Chip (SBC) from the OPTIREG Lite SBC family, designed for CAN-based applications. It integrates a 3.3 V LDO (150 mA), a 5 V LDO (100 mA), and a High-Speed CAN transceiver supporting FD communication up to 5 Mbit/s. The device features CAN Partial Networking and FD tolerant modes, compliant with ISO 11898-2:2016. Key functionalities include low-power Stop/Sleep modes with Cyclic Wake, a charge pump output for reverse polarity protection, and comprehensive supervision including watchdogs and thermal shutdown. It operates within a wide voltage range (-40 °C to +150 °C) in a PG-TSDSO-24-1 package.

Feature Summary

• Integrates 3.3 V/150 mA and 5 V/100 mA LDOs with short-circuit protection
• High-Speed CAN transceiver supporting FD communication up to 5 Mbit/s
• Supports CAN Partial Networking and FD tolerant mode per ISO 11898-2:2016
• Low quiescent current in Stop/Sleep modes with Periodic Cyclic Wake capability

Applications

• HVAC ECU and Control panel
• Light Control Unit (LCU) for front, rear, and ambient
• Seat control module and seat belt pretension
• Steering column and steering lock
• Smart power distribution modules

Procurement Notes

Verify the specific suffix 'V33' confirms the 3.3 V main regulator output. Confirm the '-3ES' designation indicates support for CAN Partial Networking and FD tolerant mode. Ensure the PG-TSDSO-24-1 package with exposed pad matches the PCB footprint requirements. Check AEC-Q100 qualification status for automotive reliability compliance.

Selection Notes

Select this variant when a 3.3 V microcontroller supply is required alongside a separate 5 V sensor supply. The '-3ES' suffix is critical for applications needing CAN Partial Networking or FD tolerance. Compare against TLE9461ESV33XUMA1 if Partial Networking features are not needed. Ensure thermal management accounts for the exposed pad in the PG-TSDSO-24-1 package.

Part Context

This component belongs to the OPTIREG Lite SBC family, offering software compatibility with TLE926x and TLE927x series. It shares the same PG-TSDSO-24-1 package as other family members, facilitating scalable design across different voltage and feature configurations within the Infineon automotive portfolio.

Replacement Considerations

TLE9461ESV33XUMA1 is a compatible alternative lacking Partial Networking features. TLE9471 variants offer DCDC regulators instead of LDOs. Verify pinout and register compatibility before substituting with other Lite SBC models.
