Infineon Technologies TLE9260QXXUMA2

Overview

TLE9260QXXUMA2 from Infineon Technologies is an automotive-grade System Basis Chip (SBC) integrating dual voltage regulators (5.0 V/150 mA and 3.3 V/100 mA), two high-side switches (HS1/HS2, 1.8 A continuous), HS-CAN transceiver supporting CAN FD, four high-voltage wake inputs (WK1–WK4), SPI interface, watchdog, reset, and thermal protection. It serves as central power management and communication hub in body control modules for 12 V vehicle electrical systems.

For engineers reviewing the TLE9260QXXUMA2 datasheet, TLE9260QXXUMA2 pinout, TLE9260QXXUMA2 application, or TLE9260QXXUMA2 equivalent, key selection criteria include CAN FD compliance, dual LDO output capability, high-side switch current rating and diagnostics, wake input voltage tolerance (up to 40 V), and fail-safe state machine behavior across SBC modes (Normal, Stop, Sleep, Fail-Safe).

Technical Context

The TLE9260QXXUMA2 implements a deterministic finite-state machine governing six operational modes-Normal, Stop, Sleep, Restart, Fail-Safe, and Development-with configurable entry/exit conditions via SPI and hardware pins. Its CAN transceiver supports dominant clamping, TXD time-out, bus wake detection, and three functional states: Normal, Receive-Only, and OFF.

Voltage supervision covers independent monitoring of VS (battery), VSHS (high-side supply), VCC1 (5 V regulator), VCC2 (3.3 V regulator), and VCAN (CAN supply), with prewarning thresholds, over/under-voltage shutdown, and short-circuit diagnostics. Thermal protection includes individual channel shutdown, prewarning at 140 °C, and full SBC thermal shutdown at 170 °C.

FAQ

What is the maximum allowable voltage on the WK1–WK4 pins?

The WK1–WK4 pins tolerate −28 V to +40 V DC continuously per datasheet Section 10.3. This enables direct connection to vehicle battery, ignition-switched lines, or sensor outputs without external level-shifting or clamping circuitry-critical for robust wake event detection in harsh automotive environments.

Does the TLE9260QXXUMA2 support CAN FD data rates above 1 Mbit/s?

Yes-the integrated HS-CAN transceiver supports CAN FD up to 5 Mbit/s in the data phase per Section 9.2 and Table 9-1. It complies with ISO 11898-2:2016 and includes TXD time-out, dominant clamping, and bus wake detection essential for high-speed, fault-tolerant automotive networks.

How does the cyclic sense feature reduce system power consumption?

Cyclic sense allows WK inputs to be sampled periodically (configurable interval) instead of continuously, reducing average current draw during Sleep mode. As described in Section 5.2.1.2, this achieves sub-100 µA quiescent current while maintaining responsiveness to critical wake events-key for always-on body electronics.

Can the HS1 and HS2 outputs drive inductive loads such as solenoids or motors?

Yes-HS1 and HS2 are rated for 1.8 A continuous current with integrated overcurrent protection, open-load detection, and thermal shutdown (Section 8.2). They support PWM dimming and are qualified for driving automotive solenoids, small DC motors, and lamps with built-in diagnostics to prevent system-level faults.
