Infineon Technologies TLE92633BQXXUMA1

Overview

TLE92633BQXXUMA1 from Infineon Technologies is a mid-range+ System Basis Chip (SBC) integrating dual LDO regulators (5 V/250 mA main, 5 V/100 mA auxiliary), one HS-CAN FD transceiver (up to 5 Mbit/s, ISO 11898-2:2016 compliant), two LIN 2.2 transceivers, four high-side switches (7 Ω typ.), two HV GPIOs, three HV wake inputs, and 16-bit SPI for configuration/diagnostics - deployed in automotive body control modules requiring integrated power, communication, and wake-up functionality.

For engineers reviewing the TLE92633BQXXUMA1 datasheet, TLE92633BQXXUMA1 pinout, TLE92633BQXXUMA1 application, or TLE92633BQXXUMA1 equivalent, this device supports CAN Partial Networking with SWK activation, FD-tolerant mode, cyclic wake, internal timer-based supervision, and fail-safe state machine operation - critical for low-power automotive ECU design and AEC-Q100-compliant system integration.

Technical Context

The TLE92633BQXXUMA1 implements a hierarchical state machine with six operational modes (Init, Normal, Stop, Sleep, Restart, Fail-Safe), each governed by configurable watchdog, interrupt, and reset outputs. Its CAN transceiver supports both standard CAN and FD-tolerant operation, enabling backward compatibility while allowing selective wake via WUP/WUF frames and protocol error counters.

Regulation architecture includes three independent voltage paths: an internal main LDO (5 V/250 mA), auxiliary LDO (5 V/100 mA), and externally controlled PNP-based regulator (5 V or 3.3 V selectable) with short-to-battery protection and load-sharing capability - all supervised by over/undervoltage, overcurrent, and thermal monitoring circuits.

FAQ

What is the maximum allowable supply voltage for TLE92633BQXXUMA1?

The absolute maximum rating for VCC is 40 V, but the functional operating range is 5.5 V to 28 V per the datasheet Rev. 1.2. Operation above 28 V risks triggering overvoltage shutdown; sustained exposure beyond 40 V may cause permanent damage. The device includes internal clamp diodes and thermal foldback to protect against load dump events up to ISO 7637-2 Pulse 5a conditions when properly decoupled.

Does TLE92633BQXXUMA1 support CAN FD Classic frames?

Yes - the integrated CAN transceiver operates in CAN FD tolerant mode per ISO 11898-2:2016, meaning it correctly receives and transmits both classical CAN (up to 1 Mbit/s) and CAN FD frames (up to 5 Mbit/s) on the same bus. It does not implement full CAN FD protocol handling (e.g., bit rate switching), but maintains electrical compatibility and timing alignment for mixed-network environments.

How many independent wake sources does TLE92633BQXXUMA1 support?

The device supports three dedicated HV wake inputs (WAKE1–WAKE3), each tolerant to 5.5–28 V, plus CAN bus activity (via WUP/WUF detection), LIN bus activity (on either LIN1 or LIN2), and internal timer expiration. All wake sources can be individually enabled/disabled via SPI configuration registers and generate distinct wake flags for precise source identification in firmware.

Can the auxiliary regulator (VREG2) power external LIN transceivers independently?

Yes - VREG2 delivers 5 V ±2 % at up to 100 mA and includes off-board usage protection, meaning it can directly power external LIN transceivers (e.g., TLE7259-3GE) without additional filtering or regulation. The datasheet explicitly validates this use case in "Potential applications" and confirms VREG2's noise immunity and load transient response meet LIN physical layer requirements per ISO 17987-3.
