Infineon Technologies TLE92633BQXXUMA2

Overview

TLE92633BQXXUMA2 from Infineon Technologies is an automotive-qualified System Basis Chip (SBC) integrating dual LDO regulators (5 V/250 mA main, 5 V/100 mA auxiliary), one high-speed CAN FD transceiver (up to 5 Mbit/s with Partial Networking and FD Tolerant mode per ISO 11898-2:2016), two LIN 2.2 transceivers, four 7 Ω high-side switches, two HV GPIOs, three HV wake inputs, SPI-based diagnostics, and fail-safe supervision. It serves as a central power management and communication hub in body control modules.

For engineers reviewing the TLE92633BQXXUMA2 datasheet, TLE92633BQXXUMA2 pinout, TLE92633BQXXUMA2 application, or TLE92633BQXXUMA2 equivalent, this device supports critical automotive subsystems requiring integrated voltage regulation, robust CAN/LIN connectivity, programmable wake-up logic, and fault-tolerant high-side switching - especially where AEC-Q100 compliance and partial networking are mandatory.

Technical Context

The TLE92633BQXXUMA2 implements a multi-state SBC controller with six operational modes (Normal, Stop, Sleep, Restart, Fail-Safe, Development), each governed by internal state machine logic and configurable via 16-bit SPI. Its CAN FD transceiver supports both full FD communication and backward-compatible FD Tolerant mode, enabling selective wake-up via WUP/WUF frames and protocol error monitoring.

Voltage regulation includes three independent paths: a main 5 V/250 mA LDO, an auxiliary 5 V/100 mA LDO, and a configurable external PNP-based regulator supporting off-board usage or load sharing. Supervision features include watchdog timer, reset output, interrupt signaling, and comprehensive diagnostic flagging (e.g., BUSERR, CANTO, SWK_SET, SYSERR).

FAQ

What is the maximum allowable supply voltage for TLE92633BQXXUMA2?

The absolute maximum rating for VCC is 36 V, but the functional operating range is 5.5 V to 28 V per datasheet Rev. 1.2. Operation below 5.5 V disables most functions including CAN/LIN transceivers and high-side switches. The device enters undervoltage lockout (UVLO) below 4.8 V and remains in reset until VCC exceeds 5.1 V with sufficient hysteresis.

Does TLE92633BQXXUMA2 support CAN FD Classic frame format?

Yes - the integrated CAN transceiver supports both CAN FD data-rate frames (up to 5 Mbit/s) and legacy CAN 2.0B frames (up to 1 Mbit/s) within the same physical layer. In FD Tolerant mode (enabled by configuration bit), it correctly receives and acknowledges Classic frames while ignoring FD-specific bit fields - ensuring interoperability with mixed-network systems.

How many independent wake sources can trigger exit from Sleep mode?

Three dedicated HV wake inputs (WAKE1–WAKE3), plus CAN bus activity (via Partial Networking), LIN wakeup pulses, and internal timer events - all configurable via SPI registers. Each HV input accepts ≥5.5 V signals directly from battery, enabling wake without relying on VREG1/VREG2 power rails.

Is external compensation required for the main voltage regulator?

No - the 5 V/250 mA main regulator (VREG1) uses internal compensation and requires only a 2.2 µF ceramic output capacitor (X7R, 10 V rating) placed close to the VREG1 pin. The datasheet specifies no external RC network; stability is guaranteed across temperature and load conditions within the specified 1–250 mA range.
