Product details

Overview

TLE7251VSJXUMA1 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-2 and ISO 11898-5, serving as the physical layer interface between CAN controllers and differential HS CAN bus. It supports data rates up to 2 MBit/s for CAN FD, features VIO voltage adaptation (2.7–5.5 V), operates across extended supply ranges (VCC: 4.5–27 V; VIO: 2.7–5.5 V), and includes bus wake-up capability with RxD-based wake indication - deployed in automotive gateway modules and body control units.

For engineers reviewing the TLE7251VSJXUMA1 datasheet, TLE7251VSJXUMA1 pinout, TLE7251VSJXUMA1 application, or TLE7251VSJXUMA1 equivalent, key selection criteria include guaranteed loop delay symmetry ≤255 ns, CANH/CANL short-circuit protection to ground/battery/VCC, stand-by mode with remote wake-up, low bus leakage current (<1 μA) in power-down state, and AEC-Q100 qualification for automotive use.

Technical Context

The TLE7251VSJXUMA1 implements dual-receiver architecture: a normal-mode receiver active during operation and a low-power receiver enabled in stand-by mode for bus wake-up detection. Its transmitter uses symmetric slew-rate control to minimize electromagnetic emission (EME) while maintaining ISO 11898-2 timing compliance.

It supports two distinct operating modes: normal mode (full TX/RX functionality, VCC powered) and stand-by mode (VCC off, VIO powered, low-power receiver active, wake-up via bus activity). Mode transition is controlled by STB pin, with built-in TxD time-out (≥1.5 ms dominant pulse detection) preventing bus lock-up.

Key Specifications

Parameter	Value and Actual Design Meaning
Bus Data Rate	Up to 2 MBit/s - enables full CAN FD frame transmission without timing violation.
Loop Delay (t_Loop)	≤255 ns - ensures bit-to-bit arbitration integrity and strict ISO 11898-2 timing compliance.
VIO Supply Range	2.7 V to 5.5 V - allows direct interfacing with 3.3 V or 5 V microcontrollers without level-shifting.
VCC Supply Range	4.5 V to 27 V - accommodates wide automotive battery voltage fluctuations including load-dump conditions.
Bus Leakage Current (Power-down)	<1 μA - preserves network quiescence and minimizes parasitic drain in sleep states.
Common-Mode Range	−27 V to +40 V - provides robust immunity against EMI and ground offset in vehicle harnesses.
ESD Robustness (IEC 61000-4-2)	±8 kV contact - eliminates need for external TVS diodes in most automotive PCB layouts.

Pinout & Package

Package: PG-DSO-8 (RoHS-compliant, halogen-free, SOIC-8 variant with exposed thermal pad).

Pin/Terminal	Circuit Role	Design Meaning
1 TxD	Transmit data input	CMOS-compatible logic input; internal pull-up to VIO; "low" = dominant bus state.
2 GND	Ground reference	Primary signal and power return; must be low-inductance connection to system ground plane.
3 VCC	Transmitter supply	Power source for CANH/CANL drivers; can be switched off in stand-by mode to reduce system power.
4 RxD	Receive data output	CMOS output indicating bus state; "low" = dominant; also signals wake-up event in stand-by mode.
5 VIO	Digital supply	Sets logic thresholds for TxD, STB, and RxD; powers low-power receiver during stand-by.
6 CANL	CAN bus low terminal	Differential bus I/O; sinks current during dominant state; short-circuit protected to GND/VCC/battery.
7 CANH	CAN bus high terminal	Differential bus I/O; sources current during dominant state; short-circuit protected to GND/VCC/battery.
8 STB	Stand-by mode control	Active-low input; internal pull-up to VIO; "low" = normal mode, "high" = stand-by mode.
Pad	Thermal pad	Connected to PCB heat sink area only; must not be electrically connected to any potential other than GND.

Key Features

Feature	Design Value
Dual-receiver architecture	Normal-mode receiver (active in normal mode) + low-power receiver (active in stand-by) enables reliable bus wake-up without VCC supply.
Guaranteed loop delay symmetry	t_Loop(H→L) and t_Loop(L→H) both ≤255 ns - ensures deterministic timing for CAN FD arbitration and sampling.
VIO-adapted logic interface	TxD, STB inputs and RxD output referenced to VIO - eliminates level-shifters when interfacing with mixed-voltage MCUs.
TxD time-out function	Auto-disables transmitter after ≥1.5 ms of continuous dominant TxD - prevents bus lock-up due to MCU fault.
Extended common-mode immunity	−27 V to +40 V common-mode range - maintains communication integrity under severe ground bounce or EMI in vehicle environments.

Applications

IC Role / Device Role / Timing Role: HS CAN interface providing noise-immune communication over long wire harnesses with ±8 kV ESD protection.

Use Value: Eliminates need for external ESD protection components and tolerates harsh electrical environments (load dump, jump start) without latch-up or damage.

Engine Control Unit (ECU)

Advanced Driver Assistance System (ADAS) Sensor Hub

Use Scenario: Real-time engine management system requiring deterministic, low-latency CAN communication with sensors and actuators.

IC Role / Device Role / Timing Role: Timing-critical transceiver ensuring sub-255 ns loop delay for accurate bit sampling and arbitration resolution at 2 MBit/s.

Use Value: Enables high-bandwidth sensor feedback and actuator command delivery essential for closed-loop combustion control and emissions compliance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed CAN transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP TJA1044GT/3	Lower VCC max (27 V vs. 27 V same); no VIO pin - logic levels fixed to VCC; lacks dedicated wake-up indication on RxD.	Requires external level-shifting for 3.3 V MCUs; wake-up detection requires additional GPIO monitoring.	Select when cost sensitivity outweighs design flexibility and integrated wake-up signaling is non-critical.
ST TJA1057G	Higher loop delay (≤300 ns); no TxD time-out function; VIO not supported - logic tied to VCC.	Not suitable for CAN FD >1 MBit/s where tight timing margins apply; no autonomous transmitter fault recovery.	Select only for legacy CAN (≤1 Mbps) applications where simplified BOM and lower gate count are prioritized.

Compared with TJA1044GT/3 and TJA1057G, the TLE7251VSJXUMA1 uniquely combines VIO adaptability, RxD-integrated wake indication, sub-255 ns loop delay, and TxD time-out - making it the only option qualified for new CAN FD designs requiring AEC-Q100 reliability and mixed-voltage MCU integration.

FAQ

What is the purpose of the VIO pin on the TLE7251VSJXUMA1?

The VIO pin supplies the digital interface circuitry and sets logic thresholds for TxD, STB, and RxD. It enables voltage-level adaptation to match the microcontroller's I/O supply (2.7–5.5 V), eliminating external level shifters. In stand-by mode, VIO remains powered to sustain the low-power receiver and wake-up detection functionality.

How does the TLE7251VSJXUMA1 achieve bus wake-up without VCC supply?

In stand-by mode, VCC is turned off while VIO remains active. The low-power receiver - powered solely by VIO - continuously monitors CANH/CANL for dominant pulses. Upon detection, it asserts a "low" on RxD, signaling wake-up to the MCU. This architecture enables true zero-VCC wake-up capability compliant with ISO 11898-5.

Does the TLE7251VSJXUMA1 support CAN FD at 2 MBit/s in all operating conditions?

Yes - the device guarantees loop delay symmetry ≤255 ns across temperature (−40°C to +150°C) and supply voltage (VCC = 4.5–27 V, VIO = 2.7–5.5 V), satisfying ISO 11898-2 timing requirements for CAN FD up to 2 MBit/s. This is validated per AEC-Q100 stress testing and confirmed in functional characterization data.

What protection features prevent damage during automotive transients?

The TLE7251VSJXUMA1 integrates protection against load dump (ISO 7637-2 Pulse 5a), jump start (±40 V), and ESD (±8 kV contact per IEC 61000-4-2). CANH/CANL pins feature short-circuit protection to ground, battery, and VCC. Overtemperature shutdown activates above +175°C, and TxD time-out prevents bus lock-up from MCU faults.
