Product details

Overview

TLE9262BQXV33 from Infineon Technologies is a mid-range+ automotive 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), a LIN 2.2 transceiver, four 7 Ω high-side switches, two HV GPIOs, and three HV wake inputs - deployed in body control modules for power management, communication, and load switching functions.

For engineers reviewing the TLE9262BQXV33 datasheet, TLE9262BQXV33 pinout, TLE9262BQXV33 application, or TLE9262BQXV33 equivalent, key selection criteria include CAN FD timing compliance, high-side switch R_DS(on) and diagnostic capability, regulator dropout behavior under cold-crank, SPI-configurable fail-safe states, and HV wake input threshold stability across temperature.

Technical Context

The device implements a hierarchical state machine with six operational modes (Normal, Stop, Sleep, Restart, Fail-Safe, Development), each governing regulator enablement, transceiver bus activity, HS-switch behavior, and wake-source sensitivity. Configuration and diagnostics are handled via a 16-bit SPI interface with CRC protection and dedicated interrupt/reset outputs.

Its CAN FD transceiver complies fully with ISO 11898-2:2016 and SAE J2284, supporting Partial Networking; the LIN transceiver meets ISO 17987-4 and SAE J2602, including flash programming capability. Voltage regulation includes short-to-battery protection on VR2 and configurable external PNP-based VR3 for off-board load sharing.

Key Specifications

Parameter	Value and Actual Design Meaning
Main Regulator Output	3.3 V ±2%, 250 mA max - powers MCU core logic and internal peripherals under full load and -40°C to +150°C ambient.
Auxiliary Regulator Output	5 V ±2%, 100 mA max - supplies LIN transceiver, sensors, or external logic with short-to-battery protection.
CAN FD Data Rate	Up to 5 Mbit/s - enables high-bandwidth gateway messaging and firmware updates without protocol translation.
High-Side Switch R_DS(on)	7 Ω typ. at 25°C - supports direct driving of resistive/inductive loads (e.g., solenoids, lamps) with integrated open-load detection.
SPI Interface	16-bit, CRC-protected - enables real-time configuration of watchdog timeout, wake sources, regulator enable/disable, and fault masking.
HV Wake Input Threshold	V_WAKE = 4.5 V min, 32 V max - detects battery-connected wake events (e.g., door handle touch, key fob signal) with hysteresis and filtering.
Operating Junction Temp	-40°C to +150°C - qualified per AEC-Q100 Grade 0, enabling placement near heat sources in BCM or HVAC modules.

Pinout & Package

Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad). Pin layout optimized for automotive PCB layout with dedicated GND planes, split supply domains (V_BAT, V_REG, V_IO), and ESD-protected wake inputs.

Pin/Terminal	Circuit Role	Design Meaning
V_BAT	Main battery supply input	Accepts 5.5–28 V DC; feeds internal regulators and high-voltage circuitry; includes overvoltage clamp at 41 V.
V_REG	Main regulator output	3.3 V regulated supply; powers internal logic, SPI interface, and connected MCU core; monitored for undervoltage reset.
VSUP	Auxiliary regulator input	Input for 5 V auxiliary regulator; requires external decoupling; enables independent power domain for LIN/CAN PHY.
HS1–HS4	High-side switch outputs	Four independently controllable 7 Ω switches; support PWM dimming, current-limited turn-on, and diagnostic reporting via SPI.
WAKE1–WAKE3	High-voltage wake inputs	32 V-tolerant inputs with programmable filter time; trigger wake-up from Sleep/Stop mode upon valid edge or level event.
CANH / CANL	CAN FD differential bus interface	Compliant with ISO 11898-2; supports dominant clamping, TXD timeout, and wake-capable bus monitoring.
LIN	Single-wire LIN transceiver I/O	Bi-directional LIN bus pin; supports slave node flash programming and slope-controlled slew rate for EMC robustness.
CSN / SCK / MOSI / MISO	SPI interface signals	4-wire SPI with chip select active-low; enables full register read/write access, including shadow registers for safe reconfiguration.

Key Features

Feature	Design Value
Dual independent regulators with off-board usage protection	Prevents backfeed from auxiliary 5 V domain into main 3.3 V rail during system power-down sequences.
Configurable external PNP-based VR3 (3.3 V or 1.8 V)	Enables load sharing with external FET for higher-current off-board rails while maintaining precise voltage setpoint and thermal derating.
Integrated fail-safe logic with watchdog and interrupt outputs	Hardware-level safety response (e.g., forced HS-switch disable, regulator shutdown) triggered by SPI timeout, overtemperature, or undervoltage.
Cyclic sense and cyclic wake with internal timer	Reduces quiescent current to ≤30 µA in Sleep mode while maintaining periodic bus monitoring and wake-source polling without MCU intervention.
Open-load and overcurrent detection per HS switch	Each high-side output reports fault status via SPI register bits, enabling diagnostic logging and adaptive load recovery strategies.

Applications

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 MC33903	Single 5 V regulator (250 mA), no 3.3 V option; CAN FD not supported (CAN 2.0 only); 3 HS switches (no PWM support)	Suitable for legacy CAN-only gateways where 3.3 V MCU supply must be provided externally	Select when CAN FD bandwidth is unnecessary and cost-sensitive LIN+CAN 2.0 integration suffices.
STPMIC1A	PMIC-only (no transceivers or HS switches); 4 buck regulators + 3 LDOs; no wake inputs or SPI diagnostics	Requires external CAN/LIN transceivers and high-side drivers - increases board area and component count	Select only when full system partitioning (power + comms + switching) is preferred for design reuse or qualification separation.

Compared with MC33903 and STPMIC1A, TLE9262BQXV33 delivers integrated CAN FD + LIN + dual regulators + four diagnostic HS switches in one AEC-Q100-qualified package - reducing interconnect complexity and enabling faster time-to-market for next-gen body electronics.

FAQ

What is the maximum junction temperature rating for TLE9262BQXV33?

The device is qualified per AEC-Q100 Grade 0 with a maximum junction temperature of +150°C. Thermal resistance (R_thJA) is 32 K/W in standard 4-layer PCB layout with 20 cm² copper pour under the exposed pad. Derating begins above +125°C ambient depending on power dissipation and airflow.

Does TLE9262BQXV33 support partial networking on the CAN FD bus?

Yes - the integrated CAN FD transceiver supports Partial Networking per ISO 11898-2:2016. It enables selective wakeup of specific nodes using targeted frame IDs, reducing overall network quiescent current. Configuration is done via SPI register bit PN_EN and associated mask registers.

Can the 3.3 V main regulator be disabled while keeping the 5 V auxiliary regulator active?

No - the 3.3 V main regulator (V_REG) powers internal logic, SPI, and CAN/LIN PHY blocks; disabling it halts all functionality. The 5 V auxiliary regulator (VSUP) can operate independently only when supplied externally and configured via SPI to bypass internal V_REG-dependent enable logic.

How is open-load detection implemented on the high-side switches?

Each HSx output includes an internal current-sense path comparing load current against a 10 mA threshold. When current falls below this value under enabled conditions, the corresponding HSx_OCD flag is set in the SPI status register. Detection works across all SBC modes except Fail-Safe, where switches are forcibly disabled.
