Product details
Overview
TLE92623BQXV33 from Infineon Technologies is an automotive-grade 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 (5 Mbit/s, ISO 11898-2:2016 compliant), 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 body control modules and gateway ECUs requiring robust power management and communication.
For engineers reviewing the TLE92623BQXV33 datasheet, TLE92623BQXV33 pinout, TLE92623BQXV33 application, or TLE92623BQXV33 equivalent, key selection criteria include CAN FD partial networking support, off-board regulator configurability via external PNP, fail-safe supervision with watchdog and interrupt outputs, and AEC-Q100 qualification for 125 °C ambient operation.
Technical Context
The TLE92623BQXV33 implements a multi-state machine architecture supporting six operational modes (Normal, Stop, Sleep, Restart, Fail-Safe, Development), each with configurable wake sources including cyclic sense, internal timer, and CAN/LIN bus activity. Its CAN FD transceiver operates in both standard and FD-tolerant modes, enabling selective wake-up via Wake-up Pattern (WUP) and Wake-up Frame (WUF) detection per ISO 11898-2.
Supervision includes independent voltage monitoring of VCC, VPRE, and external regulator feedback, plus overcurrent protection on all four high-side switches with auto-restart capability. The 16-bit SPI interface provides real-time access to 48 diagnostic flags - including BUSERR, CANTO, WUF, SYSERR, and SWK_SET - enabling precise fault isolation in distributed automotive networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Main Regulator Output | 3.3 V ±2 %, 250 mA max - powers MCU core logic and low-voltage peripherals with tight regulation under load transients. |

Key Features
| Feature | Design Value |
|---|---|
| CAN Partial Networking (PN) | Enables selective wake-up of individual ECUs via targeted WUP/WUF frames - reduces system-wide quiescent current in sleep mode. |
| Configurable External Regulator | Supports 3.3 V or 1.8 V output using external PNP transistor - allows flexible load sharing or dedicated off-board supply for safety-critical subsystems. |
| Integrated Fail-Safe Supervision | Combines watchdog timer, reset generator, interrupt output, and 48 diagnostic flags - eliminates need for discrete supervision IC in compact BMC designs. |
| HV Wake Inputs with Debounce | Three 12 V tolerant wake pins with programmable filter time - prevents false wake-ups from EMI or contact bounce in mechanical switch interfaces. |

Applications
| Body Control Module (BCM) | Vehicle Gateway |
|---|---|
Use Scenario: Centralized control of door locks, window lifts, interior lighting, and mirror adjustment in modern passenger vehicles. IC Role / Device Role / Timing Role: Primary SBC providing regulated power, CAN FD/LIN connectivity, and high-side drive for actuators - serves as power and communication hub. Use Value: Reduces BOM count by integrating regulators, transceivers, and switches; supports partial networking to cut standby current below 100 µA. | Use Scenario: Aggregation and routing of messages between CAN FD backbone, LIN subnets, and domain controllers in zonal architectures.

Use Value: Enables CAN FD data rates up to 5 Mbit/s for OTA updates while maintaining LIN compatibility for legacy sensors - simplifies software-defined vehicle integration. |
| Passive Keyless Entry (PKE) | HVAC Control Unit |
Use Scenario: Low-power entry system detecting fob proximity via LF field and authenticating via RF handshake. IC Role / Device Role / Timing Role: SBC powering ultra-low-power MCU and RF transceiver; wakes on LF pulse or CAN request with <10 µs latency. Use Value: Achieves <30 µA system sleep current using cyclic sense and CAN partial networking - extends fob battery life beyond 2 years. | Use Scenario: Climate control module managing blower motors, HVAC valves, and cabin temperature sensors. IC Role / Device Role / Timing Role: Power manager and LIN master coordinating fan speed, valve position, and sensor reads across distributed HVAC nodes. Use Value: Four integrated high-side switches directly drive 12 V blower relays and stepper motor drivers - eliminates 4 discrete driver ICs and associated passives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP FS26 | Single 3.3 V regulator (200 mA), no auxiliary 5 V regulator; supports CAN FD but lacks LIN transceiver. | Better suited for CAN-only gateways without LIN peripherals; requires external LIN transceiver and 5 V LDO. | Select when LIN is not required and board space favors smaller QFN-40 package. |
| Renesas ISL78322 | Dual 3.3 V/5 V regulators (200 mA/150 mA), no integrated CAN or LIN; adds dual watchdog and ASIL-B functional safety features. | Targeted at ASIL-B safety-critical clusters; requires external CAN/LIN PHYs and SPI-to-CAN bridge. | Select when functional safety certification (ISO 26262) is mandatory and communication PHYs are already implemented externally. |
Compared with NXP FS26 and Renesas ISL78322, the TLE92623BQXV33 uniquely integrates CAN FD, LIN, dual regulators, and four high-side switches in one AEC-Q100 Grade 0 package - reducing component count and PCB area for cost-sensitive body electronics without sacrificing feature completeness.

FAQ
What is the maximum junction temperature rating for TLE92623BQXV33?
The TLE92623BQXV33 has a maximum junction temperature of 175 °C, with thermal shutdown activation above this threshold and automatic recovery after cooling below 160 °C hysteresis. This rating supports continuous operation in engine bay environments where ambient temperatures reach 125 °C, provided PCB thermal design meets Infineon's recommended copper pour and via guidelines for the exposed thermal pad.
Does TLE92623BQXV33 support CAN FD Classic frame format?
Yes, the TLE92623BQXV33 supports CAN FD Classic (also known as CAN FD non-FD mode) at data rates up to 1 Mbit/s, in addition to full CAN FD operation up to 5 Mbit/s. It complies with ISO 11898-2:2016 and SAE J2284, enabling seamless interoperability with legacy CAN 2.0B nodes while allowing bandwidth upgrades for new ECUs - all without changing physical layer components.
How many diagnostic flags are accessible via SPI on TLE92623BQXV33?
The TLE92623BQXV33 exposes 48 distinct diagnostic flags via its 16-bit SPI interface, grouped into categories including power-on/reset status, CAN bus errors (BUSERR, CANTO, CANSIL), wake events (WUP, WUF, SWK_SET), and system faults (SYSERR, CONFIG_ERR). Each flag is individually readable in dedicated status registers, enabling precise root-cause analysis without polling overhead.
Can the auxiliary 5 V regulator be used to power external circuits safely?
Yes, the V5OUT auxiliary regulator includes built-in off-board usage protection: short-to-battery, reverse-polarity, and overcurrent limiting (100 mA trip). It is designed for direct connection to external LIN transceivers or sensors, with fault reporting via SPI diagnostic flags. No external protection circuitry is required unless operating outside the specified 5.5–28 V input range or exceeding thermal limits under sustained load.
