TLE9261QXV33XUMA1

Specialized Overview

The TLE9261QXV33XUMA1 is an OPTIREG Mid-Range+ System Basis Chip (SBC) from Infineon Technologies, designed for automotive body applications. It integrates a CAN FD transceiver compliant with ISO 11898-2, supporting data rates up to 5 Mbit/s. The device features four high-side switches with 150 mA output current capability and three voltage regulator outputs: VCC1 at 3.3 V / 250 mA, VCC2 at 5 V / 100 mA, and VCC3 configurable at 3.3 V or 1.8 V with up to 400 mA output. It operates within an input voltage range of 4.75 V to 28 V and supports AEC-Q100 Grade 1 qualification. The component utilizes a VQFN-48 package and offers low standby currents of 44 μA in Stop Mode and 15 μA in Sleep Mode.

Specialized Feature Summary

• Integrates a single CAN FD transceiver with support for high-speed communication up to 5 Mbit/s.
• Provides flexible power distribution through four independent high-side switches with diagnostic capabilities.
• Includes multiple linear voltage regulators delivering stable 3.3 V, 5 V, and configurable 1.8 V/3.3 V outputs.
• Supports efficient power management with ultra-low consumption modes including Stop and Sleep states.

Specialized Applications

• Body control modules requiring integrated power management and communication interfaces.
• Automotive lighting systems utilizing high-side switching for load control.
• Sensor interfaces powered by the integrated low-noise voltage regulators.
• Gateway nodes in vehicle networks using CAN FD for high-bandwidth data transmission.

Specialized Procurement Notes

Verify the specific suffix XUMA1 against the latest Infineon datasheet to confirm tape-and-reel packaging and RoHS compliance status. Check for any recent product discontinuation notices or lifecycle changes, as automotive PMIC availability can shift. Ensure the ordering part number matches the exact voltage regulator configuration required for your design, as variants may differ in fixed output settings.

Specialized Selection Notes

Select this component when a combined solution for CAN FD communication and multi-rail power regulation is needed for body electronics. Compare the 150 mA high-side switch current limits against your maximum load requirements. Evaluate the thermal performance of the VQFN-48 package under continuous operation conditions. Confirm compatibility with target microcontrollers such as AURIX or TRAVEO families for seamless integration.

Specialized Part Context

This part belongs to the OPTIREG Mid-Range+ SBC family, which targets mid-range automotive body applications. It complements higher-end SBCs like the TLE9263 series by offering a cost-effective solution with essential CAN FD and power switching features. The family emphasizes integration to reduce board space and simplify system architecture in modern vehicle electrical architectures.

Specialized Replacement Considerations

Check for direct pin-to-pin replacements within the TLE9261QX family that may offer updated revisions. Consider the TLE9263BQX series if additional LIN channels or higher current switches are required, noting potential software and hardware adaptation needs. Verify functional equivalence with legacy TLE9261 variants before substitution.
