Product details

Overview

TLE7263EXUMA2 from Infineon Technologies is an automotive System Basis Chip integrating HS-CAN transceiver (1 MBaud), LIN transceiver (20 kBaud), dual 5 V ±2% LDOs (150 mA each), high-side switch (150 mA), window watchdog, SPI interface, and 4 bi-level wake-up inputs - designed for CAN-LIN gateway modules in battery-connected ECUs.

For engineers reviewing the TLE7263EXUMA2 datasheet, TLE7263EXUMA2 pinout, TLE7263EXUMA2 application, or TLE7263EXUMA2 equivalent, key selection criteria include dual-regulator rail separation (VCC1 for MCU, VCC2 for internal CAN), bus-wake capability via CAN/LIN message or MONx inputs, fail-safe output (FSO) behavior during reset, and cyclic-sense-controlled HS-switch activation in Sleep Mode.

Technical Context

The device implements a dual-rail power architecture: VCC1 supplies external microcontrollers while VCC2 powers the integrated CAN transceiver and peripherals; both regulators deliver 5 V ±2% at up to 150 mA with ESR < 6 Ω capacitor support. The HS-CAN transceiver supports receive-only mode for diagnostics and bus short-circuit protection to GND and battery.

LIN compliance covers ISO 9141 and LIN specs 1.3/2.0/2.1/SAE J2602-2; MTS pin enables master termination control. SPI is 16-bit, LSB-first, with CSN-active-low protocol and tri-state DO output enabled only when CSN is low.

Key Specifications

Parameter	Value and Actual Design Meaning
CAN Data Rate	Up to 1 MBaud - supports high-speed vehicle network backbone communication
LIN Data Rate	Up to 20 kBaud - compliant with LIN 1.3/2.0/2.1 and SAE J2602-2 for body electronics subnets
VCC1 / VCC2 Output	5 V ±2%, 150 mA each - independent rails: VCC1 for MCU, VCC2 for CAN module and peripherals
Sleep Current	50 µA - enables always-on battery-connected modules with wake-up via CAN/LIN or MONx inputs
HS Switch Current	150 mA - programmable via SPI; supports periodic external wake-up circuit supply in Sleep Mode
Watchdog Type	Window watchdog with reset generation - detects firmware lockup and forces safe recovery
Fail-Safe Output	Active-low FSO - asserts low on any reset condition (UVLO, overtemp, watchdog timeout)

Pinout & Package

Package: PG-DSO-36-53 (exposed pad, thermally enhanced, GND-connected). 36-pin SOIC with exposed thermal pad (EP) internally tied to GND; requires PCB GND connection for thermal and electrical performance.

Pin/Terminal	Circuit Role	Design Meaning
MON1–MON4	Bi-level wake-up inputs	Monitor external switches/sensors; MON4 always active, others support cyclic sensing in Sleep Mode
VCC1 / VCC2	Dual LDO outputs	VCC1 powers external MCU; VCC2 powers internal CAN and optional peripherals - each requires ≥10 µF/ESR < 6 Ω capacitor
CANH / CANL	HS-CAN differential bus interface	Short-circuit protected to GND and battery; supports receive-only mode for diagnostic monitoring
RxDLIN / TxDLIN	LIN transceiver I/O	Push-pull RxDLIN (dominant = LOW); CMOS-level TxDLIN input; MTS pin controls LIN master termination
FSO / RO / WKO	Failsafe, reset, wake-up outputs	FSO: active-low supervision signal; RO: open-drain reset; WKO: active-low wake event indicator
SI / INT / STS	Sense, interrupt, sleep control	SI monitors external voltage via divider; INT signals sense events or enables flash programming (>7 V); STS triggers return-to-sleep

Key Features

Feature	Design Value
Dual independent LDOs	Separate 5 V rails (VCC1/VCC2) enable MCU and CAN subsystem isolation - critical for fault containment in gateways
Bus-wake capability	CAN/LIN message reception wakes device from Sleep/Stop modes without external hardware - reduces system BOM
Programmable HS switch	150 mA high-side output controllable via SPI; supports timed external wake-up circuit activation in Sleep Mode
Receive-only CAN mode	Enables software-based bus diagnostics without transmission - avoids network disturbance during testing
AEC-Q100 qualified	Qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient) - validated for under-hood automotive environments

Applications

Body Control Module (BCM)

Door Module Gateway

Use Scenario: Centralized control of door locks, windows, mirrors, and interior lighting via LIN slaves and CAN backbone.

IC Role / Device Role / Timing Role: System Basis Chip providing regulated 5 V power (VCC1 for MCU, VCC2 for CAN), LIN master interface, and wake-up via door handle switch (MONx).

Use Value: Enables single-chip power + communication integration - eliminates discrete LDOs, transceivers, and wake logic, reducing footprint and qualification effort.

Use Scenario: Local gateway in driver/passenger door managing mirror position, window lift, and anti-pinch sensors.

IC Role / Device Role / Timing Role: Provides isolated 5 V supplies, LIN slave interface, and HS switch to power sensor bias circuits only during active sensing cycles.

Use Value: Cyclic HS-switch activation minimizes average current draw - extends battery life in always-connected modules.

Roof Module Controller

Seat Control Unit

Use Scenario: Sunroof, panoramic roof, and ambient lighting control with LIN-connected actuators and CAN status reporting.

IC Role / Device Role / Timing Role: Supplies 5 V to MCU and CAN PHY (VCC2), monitors roof position via SI analog input, and asserts FSO on overtemperature or undervoltage.

Use Value: Integrated voltage supervision and fail-safe output replace external monitoring ICs - improves functional safety compliance (ISO 26262 ASIL-B ready).

Use Scenario: Memory seat positioning with motor drivers, position sensors, and heating elements controlled via LIN and CAN.

IC Role / Device Role / Timing Role: Delivers dual 5 V rails, supports LIN communication to seat switches, and uses MONx inputs for mechanical switch wake-up.

Use Value: Bi-level MONx inputs tolerate noisy cabin switch signals - eliminate need for external RC filters or Schmitt triggers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC33816	Single 5 V LDO (250 mA), no LIN transceiver, includes SPI-configurable watchdog and 3 HS switches	Lacks integrated LIN - requires external LIN transceiver for LIN gateway use	Select when higher HS-switch count and robust watchdog features outweigh need for integrated LIN
UJA1075A	Integrated HS-CAN + LIN + 5 V LDO (150 mA), but only one regulator rail and no HS switch	No high-side switch - external load switching required for wake-up circuitry or sensor biasing	Select when compact CAN+LIN gateway is needed without local power switching requirements

Compared with MC33816 and UJA1075A, TLE7263EXUMA2 uniquely combines dual independent LDOs, integrated LIN, and programmable HS switch - making it optimal for space-constrained, battery-powered gateways requiring autonomous wake-up and rail isolation.

FAQ

What is the function of the SPLIT pin?

The SPLIT pin provides a mid-point reference voltage for CAN bus termination resistors. It connects to the center tap of a split termination network (e.g., two 60 Ω resistors between CANH and CANL), stabilizing the recessive common-mode voltage at 2.5 V - improving EMC immunity and bus stability in automotive wiring harnesses.

How does the window watchdog operate in Stop Mode?

In Stop Mode, the window watchdog remains active and continues monitoring SPI-served refresh commands. If the watchdog is not serviced within its time window, it asserts RO (reset output) and pulls FSO low - forcing a controlled restart. This behavior ensures firmware integrity even during low-power operation.

Can VCC1 and VCC2 be used interchangeably for external loads?

No. VCC1 is designated for external microcontrollers and general-purpose 5 V loads, while VCC2 is optimized for powering the internal CAN transceiver and related circuitry. Their regulation paths and internal routing are separate - mixing loads risks violating CAN PHY timing margins or compromising MCU supply stability.

Is the exposed pad (EP) electrically connected?

Yes, the exposed pad is internally connected to GND. It must be soldered to a PCB GND plane for thermal dissipation and electrical noise suppression. Leaving it unconnected degrades thermal performance and may cause instability in high-current or high-EMI conditions.
