TLE9261QXXUMA2

Specialized Overview

The TLE9261QXXUMA2 is a mid-range System Basis Chip (SBC) from Infineon Technologies, designed for automotive applications. It integrates a high-speed CAN transceiver supporting CAN FD up to 2 Mbps, three voltage regulators including a 5V/250mA LDO, and four high-side switches with typical on-resistance of 7 Ω. The device features a 16-bit SPI interface, configurable watchdogs, and multiple wake-up sources such as cyclic sense and high-voltage inputs. Packaged in a PG-VQFN-48-31 leadless exposed-pad power package, it supports low-power modes and comprehensive diagnostic functions.

Specialized Feature Summary

• Integrates a high-speed CAN transceiver compliant with ISO11898-2 and ISO11898-5, supporting chokeless operation up to 500 kbps and CAN FD communication.
• Includes three integrated voltage regulators: a main 5V/250mA LDO for microcontroller supply, a protected 5V/100mA regulator, and an external PNP-driven regulator for load sharing or independent use.
• Features four high-side outputs with embedded protection against over-current, open-load, and short-circuit conditions, supplied by a dedicated pin.
• Provides flexible wake-up capabilities via bus messages, bi-level sensitive monitoring inputs, and periodic cyclic wake/sense functions.

Specialized Applications

• Main supply unit for microcontrollers in automotive body control modules
• Interface for CAN bus networks in vehicle comfort and convenience systems
• Power management for sensor supplies and peripheral devices

Specialized Procurement Notes

Verify the specific ordering suffix UMA2 to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints for the PG-VQFN-48-31 package. Confirm that the design accounts for the Lead Tip Inspection (LTI) feature requirements during assembly. Check for any alternative variants within the TLE926x family if different regulator counts or transceiver types are needed.

Specialized Selection Notes

Select this component when a scalable SBC solution is required for CAN-based automotive applications. It is suitable for designs needing integrated power management alongside communication interfaces. Consider the TLE9261 variant specifically when LIN transceivers are not required, unlike the TLE9262 or TLE9263 models. Ensure the application benefits from the low quiescent current in stop and sleep modes.

Specialized Part Context

The TLE9261QX belongs to the scalable Mid-Range System Basis Chip Family. It shares hardware and software compatibility with other members like the TLE9260, TLE9262, and TLE9263. This family approach allows designers to migrate between products with varying numbers of voltage regulators and transceivers without redesigning the core system architecture.

Specialized Replacement Considerations

Direct replacements within the same family include TLE9260QX for reduced regulator count or TLE9262QX/TLE9263QX for added LIN transceiver functionality. Verify pin-to-pin compatibility and register mapping consistency across the selected variant before substitution.
