TLE9263BQXXUMA1

Specialized Overview

The TLE9263BQXXUMA1 is a Mid-Range+ System Basis Chip (SBC) from Infineon Technologies, designed for automotive body applications. It integrates two low-drop voltage regulators, including a main regulator with 5 V output up to 250 mA and an auxiliary regulator with 5 V output up to 100 mA. The device features one high-speed CAN transceiver supporting FD communication up to 5 Mbit/s per ISO 11898-2:2016 and two LIN transceivers compliant with LIN 2.2 standards. It includes four high-side outputs with typical on-resistance of 7 Ω, two HV GPIOs, and three HV wake inputs. Configuration and diagnostics are managed via a 16-bit SPI interface.

Specialized Feature Summary

• Integrated power management with dual low-drop voltage regulators and external PNP transistor support for load sharing or off-board usage.
• Multi-protocol communication capabilities featuring a single CAN FD transceiver and dual LIN transceivers for robust network connectivity.
• Comprehensive supervision functions including watchdog timers, reset outputs, and thermal protection mechanisms for system reliability.

Specialized Applications

• Body Control Modules (BMC)
• Passive keyless entry and start modules
• Gateway applications
• Heating, ventilation and air conditioning (HVAC) systems

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and marking. Confirm AEC-Q100 qualification status for automotive deployment requirements. Ensure compatibility with target microcontrollers such as TRAVEO or AURIX families during design-in. Check for any recent product validation updates or discontinuation notices prior to final procurement decisions.

Specialized Selection Notes

Select this component when designing systems requiring integrated power distribution alongside CAN FD and LIN communication interfaces. Evaluate the need for multiple high-side switches and wake-up inputs for peripheral control. Consider the available voltage regulator currents and the option for external load sharing if higher current demands exist beyond internal limits.

Specialized Part Context

This part belongs to the OPTIREG™ Mid-Range+ SBC family, which combines power supply, transceiver, and power management functions in a single monolithic IC. It utilizes a PG-VQFN-48 package suitable for surface mount installation. The device is specifically engineered to reduce system complexity and cost in automotive body electronics by integrating multiple essential functions.

Specialized Replacement Considerations

Consult official replacement guides for updated variants within the TLE9263 series. Verify pin-to-pin compatibility and electrical parameter alignment before substituting. Review datasheet revisions for any functional changes in newer manufacturing batches.
