Infineon Technologies TLE92623BQXV33XUMA2

Overview

TLE92623BQXV33XUMA2 from Infineon Technologies is a mid-range+ System Basis Chip (SBC) integrating dual voltage regulators (3.3 V/250 mA main, 5 V/100 mA auxiliary), a high-speed CAN FD transceiver (up to 5 Mbit/s with Partial Networking and FD Tolerant mode per ISO 11898-2:2016), a LIN 2.2 transceiver, four 7 Ω high-side switches, two HV GPIOs, three HV wake inputs, and 16-bit SPI for diagnostics - deployed in automotive body control modules for power management, communication, and load switching.

For engineers reviewing the TLE92623BQXV33XUMA2 datasheet, TLE92623BQXV33XUMA2 pinout, TLE92623BQXV33XUMA2 application, or TLE92623BQXV33XUMA2 equivalent, this page delivers verified technical context, validated pin functions, automotive-grade supervision features, and real-world use cases in HVAC, closure modules, and gateway systems - all grounded in Infineon's Rev. 1.2 datasheet and AEC-Q100 qualification.

Technical Context

The TLE92623BQXV33XUMA2 implements a multi-state SBC architecture with five operational modes (Normal, Stop, Sleep, Restart, Fail-Safe), each governed by configurable watchdog, interrupt, and reset logic. Its CAN FD transceiver supports selective wake via cyclic sense and internal timer-based wake patterns, while maintaining full ISO 11898-2:2016 compliance including bus error detection and silence monitoring.

Voltage regulation includes three independent paths: a fixed 3.3 V main LDO (250 mA), a fixed 5 V auxiliary LDO (100 mA), and an externally configured regulator (1.8 V or 3.3 V) using an external PNP transistor - enabling off-board usage protection and load sharing with precise R_SHUNT-based current sensing.

FAQ

What is the maximum allowable supply voltage for VCC?

The absolute maximum rating for VCC is 40 V, with functional operation specified from 5.5 V to 28 V. During cold-crank conditions, the device maintains regulation down to 4.5 V input for up to 100 ms - verified per ISO 16750-2 Pulse 4a. Exceeding 40 V risks permanent damage to internal ESD structures and regulator pass elements.

Does the CAN FD transceiver support classic CAN frames alongside FD frames?

Yes - the 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 require mode switching; frame type is auto-detected based on bit timing and DLC field.

How is the external PNP regulator configured for 1.8 V output?

1.8 V output is selected by connecting REGSEL pin to GND; the external PNP (e.g., BCP56) forms a shunt-regulated stage with R_SHUNT setting current limit. The datasheet provides R_SHUNT calculation formula (R_SHUNT = 0.7 V / I_LIM) and recommends 1% tolerance resistors for ±2% output accuracy across temperature.

Are the high-side switches short-circuit protected during overtemperature events?

Yes - each HS output includes independent thermal foldback that reduces current limit progressively above 150°C junction temperature, followed by hard shutdown at 175°C. Recovery occurs only after junction cools below 145°C and SPI command resets the fault latch - preventing automatic restart into fault condition.
