Product details

Overview

TLE9262BQXXUMA1 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), a LIN 2.2 transceiver, four 7 Ω high-side switches, two HV GPIOs, three HV wake inputs, and 16-bit SPI for configuration and diagnostics. It serves as a central power management and communication hub in body control modules.

For engineers reviewing the TLE9262BQXXUMA1 datasheet, TLE9262BQXXUMA1 pinout, TLE9262BQXXUMA1 application, or TLE9262BQXXUMA1 equivalent, this device requires attention to regulator selection (5 V vs. 3.3 V main output), CAN FD partial networking enablement, HS-switch thermal derating under load, and wake input voltage thresholds (V_WAKEH = 4.5 V min, V_WAKEL = 1.8 V max).

Technical Context

The TLE9262BQXXUMA1 implements a multi-state machine with six operational modes (Init, Normal, Stop, Sleep, Restart, Fail-Safe), each governing regulator enablement, CAN/LIN bus activity, HS-switch behavior, and wake-source sensitivity. Its supervision subsystem includes windowed watchdog, configurable reset delay, and interrupt outputs tied to SPI-accessible status registers.

Regulator architecture supports flexible power partitioning: the main LDO powers core logic and CAN/LIN PHYs; the auxiliary LDO supplies external sensors or low-power peripherals; the external PNP-based regulator (via HSx pins) enables off-board load sharing or high-current auxiliary rails up to 1.5 A with external shunt resistor control.

Key Specifications

Wake Input Thresholds	V_WAKEH ≥ 4.5 V, V_WAKEL ≤ 1.8 V - supports robust wake-up from battery or ignition signals with hysteresis to reject noise.
SPI Interface	16-bit, full-duplex - provides real-time register access for configuration, fault logging, and dynamic mode switching without CPU overhead.

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 ground planes, split supply domains (V_BAT, V_REG, V_AUX), and isolated wake/CAN/LIN I/O routing.

Pin/Terminal	Circuit Role	Design Meaning
V_BAT	Main battery 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	5 V ±2 %, 250 mA - powers internal logic, CAN/LIN PHYs, and SPI interface; monitored for undervoltage/overvoltage faults.
V_AUX	Auxiliary regulator output	5 V ±2 %, 100 mA - supplies external peripherals; features independent short-circuit protection and off-board usage lockout.
HS1–HS4	High-side switch outputs	Four 7 Ω typ. drivers with open-load detection, overcurrent shutdown, and PWM-capable control via SPI registers.
WAKE1–WAKE3	High-voltage wake inputs	Three 5–28 V tolerant inputs with programmable edge sensitivity and hysteresis; trigger wake-up from Sleep/Stop modes.
CANH / CANL	CAN FD differential bus interface	Compliant with ISO 11898-2:2016; supports Normal, Receive-Only, Wake Capable, and OFF modes via SPI control.
LIN	LIN transceiver bus pin	Single-wire interface supporting LIN 2.2; integrates bus driver, receiver, and wake detection; configurable slope and TXD timeout.

Key Features

Feature	Design Value
Dual independent LDO regulators	Enables clean power separation: V_REG for safety-critical logic, V_AUX for non-critical peripherals - reducing cross-talk and simplifying EMC filtering.
CAN FD + LIN dual-bus integration	Eliminates need for discrete transceivers; supports gateway functionality between high-speed CAN domains and low-cost LIN subnets in body electronics.
Four protected high-side switches	Reduces BOM count by replacing discrete high-side drivers; built-in diagnostics (open-load, overcurrent, thermal foldback) lower system-level validation effort.
Multi-mode state machine with Fail-Safe	Provides deterministic behavior during fault conditions (e.g., regulator failure triggers controlled shutdown with interrupt assertion and reset pulse generation).
Configurable wake sources and cyclic sense	Allows ultra-low-power Sleep mode (≤ 30 µA) with periodic bus monitoring or external signal wake-up - critical for always-on automotive modules.

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
TLE9263BQX	Same pinout and feature set, but adds integrated watchdog timer with independent clock source and enhanced fail-safe sequencing.	Better suited for ASIL-B–capable designs requiring independent watchdog monitoring beyond SPI-managed supervision.	Select when functional safety compliance (e.g., ISO 26262) mandates hardware watchdog independence from main clock domain.
MC33816	Offers 3.3 V main regulator (fixed), no external PNP regulator option, and only one high-side switch (vs. four); CAN FD not supported (CAN 2.0B only).	Targeted at simpler, cost-sensitive body nodes where CAN FD bandwidth and multi-load driving are unnecessary.	Choose for legacy CAN-only systems with minimal peripheral drive requirements and fixed 3.3 V logic supply needs.

Compared with TLE9262BQXXUMA1, TLE9263BQX adds safety-critical watchdog independence but increases cost and complexity, while MC33816 reduces integration and performance to meet basic body node requirements at lower BOM cost.

FAQ

What is the maximum allowable input voltage on V_BAT?

The absolute maximum rating for V_BAT is 41 V, with internal overvoltage clamping active above this threshold. Continuous operation is specified from 5.5 V to 28 V per AEC-Q100 stress testing. Operation beyond 28 V should be limited to transient conditions (e.g., load dump), and external TVS protection is recommended for sustained >28 V exposure.

Can the main regulator output be configured for 3.3 V instead of 5 V?

No - the TLE9262BQXXUMA1 is the 5 V main regulator variant. Infineon offers a separate part number, TLE9262AQXXUMA1, for the 3.3 V main regulator version. The two variants share identical pinout and feature set but differ in internal regulator feedback network and output voltage specification.

How does the external PNP regulator configuration work?

The external regulator uses HS1 or HS2 as gate driver for an external PNP transistor (e.g., BD139), with current sensing via R_SHUNT. It supports two modes: independent regulation (off-board 5 V/3.3 V rail) or load sharing with V_REG to extend current capacity beyond 250 mA. Configuration is done via SPI register settings.

Is partial networking supported on the CAN FD transceiver?

Yes - the CAN transceiver supports Partial Networking (PN) per ISO 11898-2:2016 Annex D. It enables selective wake-up of ECUs via targeted network messages while keeping others in low-power sleep, reducing overall vehicle quiescent current. PN mode is enabled and configured via SPI registers.
