TLE9261BQXV33XUMA1

Specialized Overview

The TLE9261BQXV33 is a monolithic System Basis Chip (SBC) in an exposed pad VQFN-48 (7 mm x 7 mm) package. It integrates a main voltage regulator delivering 3.3 V up to 250 mA, an auxiliary regulator providing 5 V up to 100 mA, and an external voltage regulator configurable for 3.3 V or 1.8 V output. The device includes one high-speed CAN transceiver supporting FD communication up to 5 Mbit/s per ISO 11898-2:2016. Additional hardware features comprise four high-side outputs with typical on-resistance of 7 Ω, two HV GPIOs, and three HV wake inputs.

Specialized Feature Summary

• Integrated high-speed CAN transceiver supporting FD communication up to 5 Mbit/s
• Multiple integrated voltage regulators including main, auxiliary, and externally configurable options
• Four high-side outputs and multiple high-voltage wake inputs for system control
• Comprehensive fail-safe and supervision functions including watchdog and reset outputs

Specialized Applications

• Body Control Modules (BMC)
• Passive keyless entry and start modules
• Gateway applications
• Heating, ventilation and air conditioning (HVAC)
• Seat, roof, tailgate, trailer, door and other closure modules

Specialized Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm pinout compatibility and electrical characteristics. Confirm that the component meets AEC-Q100 automotive qualification requirements for your target application environment. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Specialized Selection Notes

Select this variant when a fixed 3.3 V main regulator output is required alongside a 5 V auxiliary supply. Consider alternative family members if LIN bus integration or different regulator configurations are needed. Verify that the available high-side current ratings and wake input thresholds align with the specific load and sensor requirements of the design.

Specialized Part Context

This component belongs to the OPTIREG Mid-Range+ SBC family, which offers scalable solutions for automotive body electronics. The TLE9261 series specifically targets applications requiring CAN connectivity without LIN support. It provides complete hardware and software compatibility across the broader product family for streamlined development.
