Product details

Overview

TLE9350BSJXTMA1 from Infineon Technologies is a high-speed CAN FD transceiver compliant with ISO 11898-2:2024 and SAE J2284-4/-5, supporting data rates up to 5 Mbit/s. It operates in automotive HS CAN networks as a physical-layer interface between microcontrollers and the CAN bus, featuring loop delay symmetry, ±10 kV HBM ESD robustness on CANH/CANL, <1 µA bus leakage in power-down mode, and integrated overtemperature protection. Used in engine control units and electric power steering systems.

For engineers reviewing the TLE9350BSJXTMA1 datasheet, TLE9350BSJXTMA1 pinout, TLE9350BSJXTMA1 application, or TLE9350BSJXTMA1 equivalent, key selection criteria include CAN FD timing symmetry, ISO 7637 transient immunity, receive-only mode control (NRM), and PG-DSO-8 thermal resistance (R_thJA = 120 K/W).

Technical Context

The TLE9350BSJXTMA1 implements a symmetric differential transmitter architecture with matched propagation delays between CANH and CANL paths, enabling reliable 5 Mbit/s CAN FD frame transmission. Its receiver incorporates a precise dominant/recessive threshold detection circuit referenced to V_CC/2, ensuring robust signal integrity across automotive temperature ranges (–40 °C to 150 °C).

Mode control is managed via two logic inputs: NEN (active-low enable) and NRM (active-low receive-only), allowing seamless transitions between normal operation, receive-only, power-save, and power-down states. Fail-safe functions include TxD timeout, short-circuit protected outputs, and thermal shutdown at 170–190 °C with 5–20 K hysteresis.

Key Specifications

Parameter	Value and Actual Design Meaning
CAN FD Data Rate	Up to 5 Mbit/s - Enables high-bandwidth firmware updates and sensor fusion in ADAS ECUs.
ESD Robustness (CANH/CANL)	±10 kV HBM - Eliminates need for external TVS diodes in most automotive harness environments.
Bus Leakage Current (Power-down)	<1 µA - Preserves battery life in always-on vehicle domains (e.g., body control modules).
Supply Voltage Range	4.5 V to 5.5 V - Matches standard automotive 5 V rail with ±10% tolerance under load dump conditions.
Thermal Shutdown Threshold	170–190 °C - Protects against latch-up during sustained overcurrent or ambient overheating in under-hood locations.
Differential Output Symmetry	Loop delay symmetry <5 ns - Ensures minimal inter-symbol interference at 5 Mbit/s, meeting ISO 11898-2:2024 jitter requirements.
Transient Immunity	Compliant with ISO 7637-2 Pulse 1/2a/3a/4 and SAE J2962-2 - Withstands load dump, jump start, and alternator ripple without reset or damage.

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
1 TxD	Transmit data input	CMOS-compatible input with internal pull-up to VCC; low = dominant bus state initiation.
2 GND	Ground reference	Primary return path for VCC and bus currents; connects to exposed thermal pad for heat dissipation.
3 VCC	Transmitter supply	5 V nominal supply; requires 1 µF decoupling capacitor to GND for stable high-speed switching.
4 RxD	Receive data output	CMOS output with dominant-low logic; directly interfaces microcontroller RX pin without level-shifting.
5 NRM	Not receive-only control	Active-low input; pulls low to disable transmitter while preserving receiver functionality for diagnostic listening.
6 CANL	CAN bus low I/O	Differential bus terminal; biased internally to 1.5 V typical in recessive state; supports common-mode range –40 V to +40 V.
7 CANH	CAN bus high I/O	Differential bus terminal; biased internally to 3.5 V typical in recessive state; matches CANL for EME reduction.
8 NEN	Not enable control	Active-low master enable; pulls low to activate transceiver; high = power-down with <1 µA quiescent current.

Key Features

Feature	Design Value
Loop delay symmetry	<5 ns matching between CANH/CANL rise/fall paths - enables clean 5 Mbit/s eye diagrams without external tuning.
EME reduction architecture	No external common-mode choke required - achieved via balanced driver design and optimized PCB layout guidance in datasheet Figure 26.
TxD timeout protection	Auto-disable after ~1.5 ms of continuous dominant TxD - prevents bus lockup due to MCU software faults.
Power-save mode	15 µA supply current with RxD active - supports low-power network wake-up monitoring without full transceiver activation.
AEC-Q100 qualification	Grade 0 (–40 °C to +150 °C junction) - certified for engine bay and transmission control unit deployment.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX33042EASA+	Supports 5 Mbit/s but lacks integrated TxD timeout; ±12 kV HBM ESD on CANH/CANL.	Requires external watchdog timer for bus lockup prevention; better suited for non-safety-critical infotainment gateways.	Select when maximum ESD margin outweighs need for autonomous fault recovery.
TCAN1042DRQ1	Lower thermal resistance (R_thJA = 90 K/W); no NRM pin - receive-only mode requires MCU-level software coordination.	Better thermal performance in compact modules; less flexible for hardware-controlled diagnostic listening.	Select for space-constrained designs where board-level thermal management is prioritized over pin-level mode control.

Compared with MAX33042EASA+ and TCAN1042DRQ1, the TLE9350BSJXTMA1 uniquely combines hardware-enforced TxD timeout, AEC-Q100 Grade 0 qualification, and dual-mode control (NEN/NRM) in a single PG-DSO-8 package-enabling safer, more autonomous operation in ASIL-B/C powertrain systems.

FAQ

What is the minimum VCC voltage required for reliable 5 Mbit/s CAN FD operation?

The TLE9350BSJXTMA1 requires VCC ≥ 4.5 V to maintain specified loop delay symmetry and differential output voltage compliance per ISO 11898-2:2024. Below 4.5 V, timing margins degrade and dominant differential voltage falls below 1.5 V, increasing bit error rate above 2 Mbit/s. Operation at 4.3 V is possible only in receive-only mode with reduced EMC immunity.

How does the NRM pin function in receive-only mode, and what happens to the transmitter stage?

When NRM is pulled low, the transmitter stage (TxD → CANH/CANL path) is completely disabled-CANH and CANL enter high-impedance state with no bus biasing. The receiver remains fully active, allowing continuous monitoring of bus traffic without affecting network arbitration. This mode draws 15 µA and supports diagnostic "listen-only" use cases without requiring MCU firmware changes.

Is external termination required on the CAN bus when using the TLE9350BSJXTMA1?

No external termination resistor is integrated into the TLE9350BSJXTMA1. Standard 120 Ω termination must be placed at each physical bus end, as defined by ISO 11898-2:2024. The device's internal bus biasing (CANH ≈ 3.5 V, CANL ≈ 1.5 V in recessive state) is not a substitute for proper termination and serves only to define idle-state common-mode voltage.

What failure conditions trigger automatic thermal shutdown, and how does recovery work?

Thermal shutdown activates when junction temperature reaches 170–190 °C, disabling both transmitter and receiver outputs. Recovery occurs after temperature falls by 5–20 K (hysteresis), at which point the device resumes normal operation if NEN and NRM are asserted correctly. During shutdown, RxD remains in high-impedance state-no bus disturbance occurs, preserving network integrity.
