Product details
Overview
TLE92623BQXXUMA1 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), 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 configuration/diagnostics - deployed in body control modules and gateway nodes.
For engineers reviewing the TLE92623BQXXUMA1 datasheet, TLE92623BQXXUMA1 pinout, TLE92623BQXXUMA1 application, or TLE92623BQXXUMA1 equivalent, this device supports critical automotive power management, communication, and load switching functions with fail-safe supervision, cyclic wake capability, and AEC-Q100 qualification for harsh environments.
Technical Context
The TLE92623BQXXUMA1 implements a multi-state SBC architecture with Normal, Stop, Sleep, Restart, Fail-Safe, and Development modes managed via SPI-configurable registers and hardware pins. Its CAN FD transceiver supports both standard and FD Tolerant operation, enabling seamless integration into legacy and next-gen vehicle networks.
Supervision includes watchdog timeout detection, interrupt/reset outputs, and comprehensive diagnostics flags (e.g., BUSERR, CANTO, WUF, SYSERR). Wake functionality combines CAN-based selective wake (SWK), cyclic sense, internal timer, and HV wake inputs - all configurable for ultra-low-power sleep states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Main regulator output | 5 V ±2 % at up to 250 mA - powers MCU core or domain controller directly with low dropout and thermal foldback protection. |
| Auxiliary regulator output | 5 V ±2 % at up to 100 mA - supplies off-board peripherals with short-to-battery protection and independent enable control. |
| CAN FD data rate | Up to 5 Mbit/s with Partial Networking support - enables selective node wake-up and reduced bus traffic during sleep without requiring full network activation. |
| LIN compliance | LIN 2.2 / ISO 17987-4 / SAE J2602 - interoperable with standard automotive LIN slaves for sensor/actuator interfaces. |
| High-side switch RDS(on) | 7 Ω typ. - drives resistive or inductive loads (e.g., solenoids, lamps) with overcurrent and overtemperature shutdown. |
| SPI interface | 16-bit serial peripheral interface - provides real-time register access for configuration, status monitoring, and fault logging with CRC error detection. |
| Operating temperature | −40 °C to +150 °C ambient - qualified per AEC-Q100 Grade 0 for under-hood and cabin-mounted applications. |

Key Features
| Feature | Design Value |
|---|---|
| Dual LDO regulation with off-board usage protection | Enables safe powering of external sensors/actuators while preventing reverse-current flow or battery drain during sleep. |
| CAN FD Partial Networking with SWK | Allows targeted wake-up of specific ECUs via dedicated wake frames - reducing system-wide current consumption in standby. |
| Configurable high-side switches with diagnostics | Each HS output reports overcurrent, open-load, and short-to-ground faults via SPI, enabling predictive maintenance and safe shutdown. |
| Multi-mode SBC state machine | Supports five distinct operational states (Normal, Stop, Sleep, Restart, Fail-Safe) with deterministic transitions and hardware/firmware triggers. |
| Integrated fail-safe supervision | Combines windowed watchdog, reset generation, interrupt signaling, and 12+ diagnostic flags for ASIL-B–capable system monitoring. |
Applications
| Body Control Module (BCM) | Passive Keyless Entry & Start (PKES) |
|---|---|
Use Scenario: Centralized control of door locks, interior lighting, and window lifts in modern vehicles. IC Role / Device Role / Timing Role: SBC provides regulated power, LIN communication to door modules, CAN FD gateway routing, and high-side drive for lock actuators. Use Value: Reduces BOM count by integrating power, comms, and switching - simplifying PCB layout and improving thermal reliability in compact BCM housings. |
Use Scenario: Secure authentication and engine start initiation via proximity fob detection and immobilizer handshake. IC Role / Device Role / Timing Role: Manages low-power wake via HV inputs from door handle sensors, executes secure CAN FD messaging, and powers RF receiver ICs via VREG2. Use Value: Enables sub-100 µA sleep current with fast (<100 ms) wake-to-communication latency - meeting OEM PKES responsiveness requirements. |
| Automotive Gateway | HVAC Control Unit |
Use Scenario: Protocol translation and message routing between CAN FD backbone, LIN subnets, and diagnostic interfaces. IC Role / Device Role / Timing Role: Acts as bridge node with dual CAN FD channels (not applicable here) and LIN transceiver; uses SPI to interface with gateway MCU. Use Value: Supports simultaneous CAN FD and LIN traffic with hardware-level Partial Networking - eliminating software polling overhead and minimizing gateway MCU wake cycles. |
Use Scenario: Climate control actuation including blower motor, blend door actuators, and display backlighting. IC Role / Device Role / Timing Role: Supplies 5 V to HVAC MCU and sensors, drives blower relays via HS outputs, and receives HVAC command signals over LIN. Use Value: Integrates 4× high-side drivers with built-in current limiting - replacing discrete FETs and sense resistors while providing real-time fault reporting to HVAC ECU. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive SBC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP FS26 | Single 5 V/300 mA regulator; no auxiliary LDO; includes ASIL-D safety features and embedded voltage monitor. | Better suited for safety-critical ADAS domains requiring ISO 26262 certification; lacks integrated LIN transceiver. | Select FS26 when functional safety compliance (ASIL-D) is mandatory and LIN is handled externally. |
| Renesas ISL78322 | Dual 3.3 V/200 mA regulators; no CAN FD; only basic CAN 2.0B and LIN; no high-side switches. | Targeted at lower-complexity body electronics where FD bandwidth and local load driving are unnecessary. | Choose ISL78322 for cost-sensitive, non-FD applications needing only basic power + comms without integrated switching. |
Compared with NXP FS26 and Renesas ISL78322, the TLE92623BQXXUMA1 uniquely balances CAN FD performance, dual-LDO flexibility, on-chip high-side switching, and LIN integration - making it optimal for mid-tier automotive body/gateway nodes where feature density and AEC-Q100 Grade 0 robustness are prioritized over ASIL-D certification or ultra-low cost.

FAQ
What is the maximum operating junction temperature for TLE92623BQXXUMA1?
The device is rated for junction temperatures up to +150 °C and qualified per AEC-Q100 Grade 0. Thermal resistance θJA is 35 K/W (typ.) in standard 4-layer PCB layout with 20 cm² copper pour under the exposed pad. Derating curves in Section 4.3 of the datasheet define safe operating area based on ambient temperature and power dissipation.
Does TLE92623BQXXUMA1 support CAN FD Classic frame format?
Yes - the integrated CAN transceiver operates in CAN FD Tolerant mode per ISO 11898-2:2016, fully compatible with Classical CAN (CAN 2.0B) frames at up to 1 Mbit/s and CAN FD frames (with extended data length) up to 5 Mbit/s. It does not require external arbitration or protocol translation.
How is the external PNP-based voltage regulator configured?
Voltage Regulator 3 is implemented using an external PNP transistor (e.g., BCP56) connected to the VR3 pin. Configuration is done via SPI register VR3_CFG to select either independent regulation (5 V/3.3 V) or load-sharing mode with the main regulator. RSHUNT value is calculated per Section 8.4 of the datasheet to set current limit.
Can all four high-side switches be operated simultaneously at full load?
No - simultaneous full-load operation (250 mA each) exceeds thermal limits. The datasheet specifies a maximum total power dissipation of 1.8 W at TA = 85 °C. With 7 Ω RDS(on), concurrent 250 mA switching across all four HS outputs generates ~1.75 W - requiring strict derating or staggered activation in thermally constrained layouts.
