Infineon Technologies TLE9263QXXUMA2

Overview

TLE9263QXXUMA2 from Infineon Technologies is an automotive-grade System Basis Chip (SBC) integrating dual low-dropout voltage regulators (5 V/150 mA and 3.3 V/100 mA), a high-speed CAN FD transceiver, three LIN transceivers, four high-side switches, and high-voltage wake inputs. It supports ASIL-B functional safety requirements and operates across –40 °C to +150 °C ambient temperature in body control modules for vehicle door, lighting, and seat systems.

For engineers reviewing the TLE9263QXXUMA2 datasheet, TLE9263QXXUMA2 pinout, TLE9263QXXUMA2 application, or TLE9263QXXUMA2 equivalent, this device is selected for its integrated power management, multi-protocol communication capability, and robust wake-up supervision in automotive ECU designs requiring compact system integration and ISO 11898-2/ISO 17987 compliance.

Technical Context

The TLE9263QXXUMA2 implements a state-machine-based SBC architecture with five operational modes-Normal, Stop, Sleep, Restart, and Fail-Safe-each with defined power states, regulator enablement, and transceiver activity. Its CAN FD interface supports data rates up to 5 Mbit/s with bus dominant clamping and TXD time-out protection.

Three LIN transceivers operate independently per ISO 17987-2/4, supporting flash programming via LIN and slope selection for EMC optimization. The four high-side switches feature open-load detection, overcurrent shutdown, PWM timing control, and coordinated operation across SBC modes.

FAQ

What is the maximum allowable supply voltage for TLE9263QXXUMA2?

The absolute maximum rating for VCC is 40 V, but the functional operating range is 5.5 V to 28 V per the datasheet. Operation above 28 V may trigger overvoltage protection and disable regulators or HS switches. Transient spikes up to 40 V are tolerated for ≤200 ms during load dump conditions, provided external clamping (e.g., TVS diode) is used per design guidelines.

Does TLE9263QXXUMA2 support CAN FD Classic arbitration and flexible data-rate operation?

Yes, the integrated CAN transceiver complies with ISO 11898-2:2016 and supports both Classical CAN (up to 1 Mbit/s) and CAN FD (up to 5 Mbit/s) with separate bit timing configuration for arbitration and data phases. It includes automatic protocol detection and seamless transition between modes without firmware intervention.

How many LIN transceivers can operate simultaneously, and are they electrically isolated?

All three LIN transceivers (LIN1–LIN3) operate independently and concurrently, each with dedicated TX/RX pins and configurable baud rates (1.2–20 kbit/s). They share no internal electrical isolation-external galvanic separation must be implemented if required by system architecture-but each meets ISO 17987-2 EMC and fault tolerance specifications individually.

What diagnostic capabilities do the high-side switches provide?

Each HS1–HS4 channel provides open-load detection (via current sense), overcurrent shutdown (with auto-retry or latched behavior), overtemperature shutdown, and supply undervoltage/overvoltage cutoff. Diagnostic status is reported via SPI register reads and can trigger interrupt or fail-output signals for system-level fault handling.
