Product details

Overview

TLE9262BQXV33 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 per ISO 11898-2:2016), a LIN 2.2 transceiver, four 7 Ω high-side switches, two HV GPIOs, and three HV wake inputs - deployed in automotive body control modules for power management, communication, and load driving.

For engineers reviewing the TLE9262BQXV33 datasheet, TLE9262BQXV33 pinout, TLE9262BQXV33 application, or TLE9262BQXV33 equivalent, this device supports AEC-Q100 qualified designs requiring integrated CAN FD/LIN, configurable external regulator support, fail-safe supervision, and multi-mode power state control in space-constrained automotive ECUs.

Technical Context

The TLE9262BQXV33 implements a hierarchical state machine with six operational modes (Normal, Stop, Sleep, Restart, Fail-Safe, Development), each governing regulator enablement, transceiver behavior, and switch control via SPI-configurable registers. Its CAN FD transceiver supports partial networking and bus dominant clamping, while the LIN transceiver includes flash programming capability and slope selection.

Supervision functions include a windowed watchdog with programmable timeout, interrupt and reset outputs tied to internal fault detection (overvoltage, undervoltage, overtemperature), and cyclic wake sensing with internal timer-based polling - all coordinated through a 16-bit SPI interface that enables real-time diagnostics and configuration without host CPU intervention.

Key Features

Feature	Design Value
Configurable external regulator support	3.3 V or 1.8 V output via external PNP transistor - enables load sharing or off-board usage with programmable current limit.
Multi-mode power state management	Six distinct SBC states (Normal, Stop, Sleep, Restart, Fail-Safe, Development) - reduces quiescent current to ≤20 µA in Sleep mode with wake-on-LIN/CAN/HV inputs.
Integrated fail-safe supervision	Windowed watchdog, undervoltage/overvoltage lockout, thermal shutdown, and interrupt/reset outputs - ensures deterministic recovery on system faults.
Cyclic wake sensing	Programmable interval (1–255 ms) for periodic wake-up and sensor polling - eliminates need for external RTC or microcontroller wake timer.
Diagnostic-rich SPI interface	16-bit register map with real-time status flags (e.g., HSx open-load, CAN bus-off, LIN sync error) and fault history storage - simplifies ECU-level diagnostics and ASAM-compliant logging.

Applications

Body Control Module (BCM)

Passive Keyless Entry (PKE)

Use Scenario: Centralized power distribution and communication hub managing door locks, interior lighting, and window lifters in modern vehicles.

IC Role / Device Role / Timing Role: System Basis Chip providing regulated 3.3 V/5 V rails, CAN FD gateway connectivity, LIN sub-network control, and high-side switching for actuator drivers.

Use Value: Reduces BOM count by integrating regulators, transceivers, and switches - enabling compact 48-pin QFN footprint and eliminating discrete supervisor ICs.

Use Scenario: Secure vehicle access module detecting key fob proximity and initiating engine start sequence via CAN/LIN handshaking.

IC Role / Device Role / Timing Role: Low-power SBC managing wake-on-RF signal, LIN-based authentication, and CAN FD command forwarding to ECU with fail-safe reset coordination.

Use Value: Achieves ≤20 µA Sleep current with HV wake inputs and cyclic sense - extending battery life in always-on PKE receivers.

Roof Module (Sunroof/Convertibles)

Tailgate/Trailer Control

Use Scenario: Motorized sunroof or panoramic roof actuation with position feedback, obstacle detection, and anti-pinch safety logic.

IC Role / Device Role / Timing Role: High-side driver controller supplying motor H-bridge power stages, monitoring current via external shunt, and communicating status over LIN to BCM.

Use Value: Integrated open-load and overcurrent detection on HS1–HS4 enables real-time motor stall/fault identification without external comparators.

Use Scenario: Trailer lighting and brake control module interfacing with vehicle CAN network and trailer harness via dedicated high-voltage outputs.

IC Role / Device Role / Timing Role: Robust high-side switch driver (7 Ω R_DS(on)) with wake-on-trailer-connect detection and LIN-based configuration of trailer type (LED/incandescent).

Use Value: Three HV wake inputs detect trailer attachment events; auxiliary 5 V regulator powers trailer-side LIN slaves directly.

Equivalent & Alternatives

The following parts are listed as comparable options for similar System Basis Chip applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9263BQXV33	Same package and pinout; adds 1.8 V main regulator option and enhanced LIN timing accuracy (±1.5 % vs. ±2 %).	Preferred for new designs requiring tighter LIN baud rate tolerance or 1.8 V MCU core supply.	Select when 1.8 V regulation or improved LIN timing stability is required; otherwise TLE9262BQXV33 offers cost-optimized 3.3 V/5 V dual-rail solution.
MC33816PAE	NXP part with 3.3 V/250 mA main regulator, LIN 2.2, but only one high-side switch and no CAN FD (CAN 2.0B only).	Suitable for simpler LIN-only nodes without CAN FD or multi-load driving needs.	Choose for LIN-centric, low-complexity modules where CAN FD bandwidth and four HS outputs are unnecessary.

Compared with TLE9263BQXV33, the TLE9262BQXV33 trades 1.8 V regulator flexibility and tighter LIN timing for lower cost and identical 3.3 V/5 V dual-rail performance; versus MC33816PAE, it delivers higher integration (CAN FD + 4 HS switches) at the expense of broader vendor ecosystem support.

FAQ

What is the maximum allowable input voltage for the VCC_MAIN pin?

The absolute maximum rating for VCC_MAIN is 40 V, but the functional operating range is 5 V to 28 V per the datasheet's "Functional Range" section. Operation above 28 V risks triggering undervoltage lockout or thermal shutdown; sustained operation beyond 36 V may cause permanent damage. Designers must ensure transient suppression (e.g., TVS diode) for load-dump conditions.

Can the TLE9262BQXV33 operate without an external microcontroller?

No - the TLE9262BQXV33 requires an external host MCU for SPI initialization, mode transitions, and diagnostic interpretation. It lacks autonomous firmware or boot ROM; all configuration (e.g., watchdog timeout, wake intervals, regulator enable) is SPI-mapped and non-volatile only if stored externally. The SBC executes state transitions but does not make decisions independently.

How does the external voltage regulator function differ from the integrated regulators?

The external regulator path uses an external PNP transistor controlled by the TLE9262BQXV33's VREG3 pin to deliver either 3.3 V or 1.8 V, with current limiting set by R_SHUNT. Unlike the fixed 3.3 V/5 V integrated regulators, this path supports load sharing (with VOUT_MAIN) or standalone off-board usage, and its output voltage is selected via SPI register configuration - enabling flexible power architecture for mixed-voltage MCUs.

Is partial networking supported on the CAN FD transceiver?

Yes - the CAN FD transceiver supports Partial Networking (PN) per ISO 11898-2:2016 Annex D. When enabled via SPI, the transceiver enters PN mode upon receiving targeted remote frames, allowing selective node wake-up without global bus activation. This reduces system-wide quiescent current during Sleep mode and is confirmed in Section 10.2.4 of the datasheet.
