Product details

Overview

TLE9262BQXXUMA2 from Infineon Technologies is a mid-range+ System Basis Chip (SBC) integrating dual LDO regulators (5 V/250 mA main, 5 V/100 mA auxiliary), HS-CAN FD transceiver (up to 5 Mbit/s), LIN 2.2 transceiver, four 7 Ω high-side switches, two HV GPIOs, and three HV wake inputs. It serves as a central power management and communication hub in automotive body electronics modules.

For engineers reviewing the TLE9262BQXXUMA2 datasheet, TLE9262BQXXUMA2 pinout, TLE9262BQXXUMA2 application, or TLE9262BQXXUMA2 equivalent, this device supports CAN FD partial networking, configurable external PNP regulator load sharing, fail-safe supervision, SPI-based diagnostics, and AEC-Q100 qualified operation for harsh automotive environments.

Technical Context

The TLE9262BQXXUMA2 implements a multi-state SBC state machine (Init, Normal, Stop, Sleep, Fail-Safe, Development) with cyclic sense/wake capabilities and internal timer-based wake sources. Its CAN transceiver complies with ISO 11898-2:2016 and SAE J2284, supporting dominant clamping, TXD time-out, and undervoltage detection.

LIN functionality meets ISO 17987-4 and SAE J2602, including slope selection, flash programming via LIN, and receive-only mode. High-side switches feature open-load detection, overcurrent protection, PWM/timer control, and mode-dependent operation across all SBC states.

Use Scenario: Centralized power and communication management for door locks, window lifts, mirrors, and interior lighting.

IC Role / Device Role / Timing Role: System Basis Chip providing regulated power, CAN/LIN connectivity, and high-side switching for actuator control.

Use Value: Eliminates need for discrete regulators, transceivers, and switch drivers-reducing PCB area by >30% and improving EMI performance.

Use Scenario: Low-power remote authentication and vehicle unlock/start sequence coordination.

IC Role / Device Role / Timing Role: Wake-capable SBC managing secure LIN handshake, CAN gateway handoff, and HV wake detection from fob signals.

Use Value: Achieves <10 µA sleep current with reliable wake latency <100 ms, meeting OEM ultra-low-power requirements.

Automotive HVAC Control Unit

Trailer Control Module

Use Scenario: Fan speed control, blend door actuation, and climate sensor interfacing in cabin air systems.

IC Role / Device Role / Timing Role: Power manager and LIN master coordinating multiple slave actuators and sensors via single-wire bus.

Use Value: Integrated LIN transceiver with flash programming support enables field-upgradable firmware without additional programming hardware.

Use Scenario: Monitoring and controlling trailer lights, brakes, and ABS signals via vehicle-to-trailer CAN link.

IC Role / Device Role / Timing Role: CAN FD gateway with fail-safe monitoring, high-side switching for trailer load control, and wake-on-CAN capability.

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 package and pinout; adds third high-side switch and enhanced watchdog features.	Better suited for modules requiring ≥5 switched loads or stricter ASIL-B compliance.	Select when additional HS output or extended safety diagnostics are required; not drop-in due to register map differences.
MC33816	16-pin SOIC; single 5 V/250 mA regulator; no LIN; CAN only up to 1 Mbit/s.	Targeted at cost-sensitive, lower-complexity body modules without LIN or FD needs.	Choose for simpler designs where footprint and protocol scope are constrained; lacks HV wake inputs and auxiliary regulator.

Compared with TLE9262BQXXUMA2, TLE9263BQX offers expanded switching capacity and safety features but requires firmware adaptation, while MC33816 reduces integration level and protocol capability-making it suitable only for non-FD, LIN-free applications with tighter cost targets.

FAQ

What is the maximum ambient temperature rating for continuous operation?

The TLE9262BQXXUMA2 is rated for continuous operation from −40 °C to +125 °C ambient, with junction temperature up to +150 °C under specified thermal conditions (R_thJA = 35 K/W). Derating applies above 105 °C ambient depending on power dissipation and PCB copper area.

Does the device support partial networking in CAN FD mode?

Yes, the integrated HS-CAN transceiver supports Partial Networking (PN) per ISO 11898-2:2016, allowing selective wake-up of network nodes via targeted remote frames while keeping others in low-power sleep mode-critical for energy-efficient gateways.

Can the auxiliary regulator be used to power external microcontrollers?

Yes, the auxiliary regulator (5 V/100 mA) is designed for off-board usage with built-in short-circuit and overtemperature protection. It supports direct connection to external MCUs or sensors, provided load current remains within 100 mA and input voltage stays within 5–28 V.

How many wake sources does the device support simultaneously?

The TLE9262BQXXUMA2 supports three dedicated HV wake inputs (HVWAKE1–HVWAKE3), plus CAN and LIN bus activity, internal timer, and cyclic sense as additional wake sources-enabling up to six independent wake triggers in Sleep mode.
