Product details
Overview
TLE9261BQXV33 from Infineon Technologies is an automotive-grade System Basis Chip (SBC) integrating a 3.3 V/250 mA main voltage regulator, a 5 V/100 mA auxiliary regulator, a high-speed CAN FD transceiver (up to 5 Mbit/s), four 7 Ω high-side switches, and three high-voltage wake inputs. It serves as a centralized power management and communication interface in body control modules for vehicle closure systems and lighting.
For engineers reviewing the TLE9261BQXV33 datasheet, TLE9261BQXV33 pinout, TLE9261BQXV33 application, or TLE9261BQXV33 equivalent, this device supports CAN FD partial networking, configurable external PNP-based 3.3 V/1.8 V regulator, SPI-based diagnostics, fail-safe supervision, and cyclic wake functionality - critical for low-power automotive body electronics design.
Technical Context
The TLE9261BQXV33 implements a multi-state SBC controller with six operational modes (Normal, Stop, Sleep, Restart, Fail-Safe, Development), each governed by internal state machine logic and configurable via 16-bit SPI. Its CAN transceiver complies fully with ISO 11898-2:2016 and SAE J2284, supporting dominant clamping, TXD time-out, and wake-capable bus monitoring.
Voltage regulation includes three independent paths: integrated 3.3 V main LDO, 5 V auxiliary LDO, and externally controlled regulator (selectable 3.3 V or 1.8 V) using an external PNP transistor. Supervision features include watchdog timeout, reset generation, interrupt signaling, and over/undervoltage detection on all regulators and HS outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Main Regulator Output | 3.3 V ±2 %, 250 mA max - powers MCU core or CAN controller directly with tight tolerance and sufficient current for mid-tier automotive microcontrollers. |
| Auxiliary Regulator Output | 5 V ±3 %, 100 mA max - supplies sensors, LIN transceivers, or external logic requiring stable 5 V rail with off-board usage protection. |
| CAN FD Data Rate | Up to 5 Mbit/s - enables high-bandwidth communication for gateway and domain controller applications compliant with modern automotive network architecture. |
| High-Side Switch RDS(on) | 7 Ω typ. - delivers robust load driving capability for resistive and inductive loads (e.g., solenoids, lamps) with integrated open-load and overcurrent detection. |
| Wake Inputs | 3 HV wake pins (WK1–WK3), 5–28 V operating range - enables reliable wake-from-sleep via battery-supplied signals without external level-shifting circuitry. |
| SPI Interface | 16-bit, full-duplex, 3-wire - provides real-time configuration, status readback, and diagnostic reporting for functional safety compliance (ASIL-B capable). |

Key Features
| Feature | Design Value |
|---|---|
| Configurable External Regulator | Selectable 3.3 V or 1.8 V output using external PNP transistor - enables flexible power tree design for mixed-voltage SoCs while retaining load-sharing and short-to-battery protection. |
| Cyclic Wake Function | Programmable wake interval (1 ms to 65 s) with internal timer - eliminates need for external RTC or microcontroller wake polling, reducing system standby current. |
| Fail-Safe Mode | Hardware-enforced safe state activation on critical faults (e.g., overtemperature, regulator failure) - forces HS outputs OFF and asserts dedicated fail outputs FO1–FO3. |
| Partial Networking Support | CAN FD transceiver enters low-power listen-only mode while maintaining wake capability - enables selective node activation without bus disturbance in domain controllers. |
| Integrated Supervision | Independent watchdog timer, reset generator, interrupt output, and voltage monitors for all regulators and HS outputs - reduces external BOM count for ASIL-B-compliant designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9262BQXV33 | Same package and pinout; replaces auxiliary 5 V regulator with second 3.3 V regulator (250 mA); no external PNP regulator option. | Better suited for dual 3.3 V domain architectures (e.g., MCU + CAN controller), but lacks 5 V rail for legacy sensors. | Select when system uses only 3.3 V peripherals and requires higher auxiliary current capacity. |
| MC33816AER2 | NXP part with 3.3 V/200 mA main regulator, 5 V/150 mA auxiliary, LIN 2.2 interface instead of CAN FD, and only two HS switches. | Targeted at cost-sensitive LIN-based body nodes (e.g., seat controls); lacks CAN FD, cyclic wake, and external regulator configurability. | Choose for LIN-only applications where CAN FD bandwidth and advanced wake features are unnecessary. |
Compared with TLE9261BQXV33, TLE9262BQXV33 offers higher auxiliary current at the expense of 5 V flexibility, while MC33816AER2 trades CAN FD and wake sophistication for LIN compatibility and lower gate count - making TLE9261BQXV33 optimal for CAN FD–enabled, thermally constrained, multi-rail body ECUs.

FAQ
What is the maximum ambient temperature rating for continuous operation?
The TLE9261BQXV33 is qualified per AEC-Q100 Grade 0 with a junction temperature range of −40 °C to +150 °C. At 100 °C ambient, it sustains full 250 mA main regulator output with proper PCB copper pour and thermal vias under standard JEDEC 2-layer board conditions.
Does the device support CAN FD Classic arbitration and FD data phases simultaneously?
Yes - the integrated CAN transceiver fully supports ISO 11898-2:2016, enabling simultaneous Classic CAN arbitration (1 Mbit/s) and CAN FD data phases (up to 5 Mbit/s) on the same bus, with automatic protocol detection and seamless transition between frame types.
How is the external PNP-based regulator configured for 1.8 V output?
Voltage selection is set via SPI register bit EXTVREG_SEL: '0' configures 3.3 V, '1' selects 1.8 V. The external PNP transistor (e.g., PBSS4041P) and resistor divider must be sized per datasheet Section 8.4 to achieve target output with ±2 % accuracy across temperature and load.
Can WK1 and WK2 be used simultaneously for analog voltage measurement?
No - WK1 and WK2 share a single ADC channel; only one can operate in analog measurement mode at a time. When enabled, they provide 10-bit resolution over 0–28 V range with internal 1.2 V reference, supporting battery voltage monitoring or sensor input scaling.
