Product details

Overview

L9616-TR from STMicroelectronics is an AEC-Q100 qualified automotive high-speed CAN transceiver in SO-8 package, supporting data rates up to 1 Mbaud with dual-slope control (≤1 Mbaud / ≤250 kbaud), ±4 kV ESD protection, and bus voltage tolerance from −5 V to +36 V. It interfaces between a CAN controller and physical bus in vehicle body control modules, powertrain gateways, and ADAS domain controllers.

For engineers reviewing the L9616-TR datasheet, L9616-TR pinout, L9616-TR application, or L9616-TR equivalent, this page delivers verified electrical characteristics, slope-selectable EMC-optimized timing behavior, short-circuit detection with shutdown, and common-mode input range of −2 V to VS+3 V - all critical for robust automotive network design.

Technical Context

The L9616-TR implements a differential transmitter with adjustable slew rate via ASC pin: grounding ASC enables high-speed mode (20–50 V/μs), while connecting ASC to VS selects low-speed mode (5–20 V/μs) for reduced RFI. Its receiver features 700 mV typical differential threshold and 150 mV hysteresis for noise immunity.

Short-circuit protection activates within 1–10 μs when C_H/C_L are shorted or connected to battery, disabling outputs and limiting supply current to ≤150 mA. The device operates across −40 °C to +125 °C with supply voltage 4.5–5.5 V and supports common-mode input range from −2 V to +7 V (VS = 5 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	Up to 1 Mbaud - supports full-speed CAN FD physical layer compatibility in legacy CAN networks.
Slew Rate Control	Two-state via ASC pin: 20–50 V/μs (ASC = GND) or 5–20 V/μs (ASC = VS) - directly reduces EMI during board-level emissions testing.
Bus Voltage Range	−5 V to +36 V on C_H/C_L - withstands load dump, reverse battery, and jump-start conditions per ISO 7637-2.
Differential Threshold	700 mV typ., 500–900 mV min/max - ensures reliable dominant/recessive state detection under noisy ground conditions.
ESD Protection	±4 kV HBM - meets IEC 61000-4-2 Level 3 for in-vehicle harness coupling immunity.
Common-Mode Range	−2 V to VS+3 V - supports operation with ground offsets up to 3 V above supply, critical for multi-node chassis-grounded systems.
Short-Circuit Detection	1–10 μs response time, auto-shutdown - prevents thermal runaway and preserves system-level power budget during fault events.

Pinout & Package

Package: SO-8 (ECOPACK® compliant, 1.27 mm pitch, 4.9 × 6.0 mm body, 1.75 mm max height).

Pin/Terminal	Circuit Role	Design Meaning
1 TXO	Transmitter input	CMOS-compatible logic input from CAN controller; accepts 0.7×VS high level and 0.3×VS low level.
2 GND	Ground reference	Primary return path for supply and signal currents; must be low-inductance connection to chassis ground.
3 VS	Supply voltage	4.5–5.5 V nominal; powers internal regulators and output stages; decoupling capacitor required at pin.
4 RXO	Receiver output	CMOS output driving CAN controller RX pin; active-high dominant, active-low recessive.
5 RX1	Reference voltage output	0.5×VS ±5% buffered reference for external biasing or diagnostic monitoring.
6 C_L	Low-side CAN bus line	Differential bus terminal; short-circuit protected to −5 V and +36 V; connects to CAN_L wire.
7 C_H	High-side CAN bus line	Differential bus terminal; short-circuit protected to −5 V and +36 V; connects to CAN_H wire.
8 ASC	Adjustable slope control	Selects slew rate: GND = high speed (≤1 Mbaud), VS = low speed (≤250 kbaud) for EMI reduction.

Key Features

Feature	Design Value
AEC-Q100 Grade 0 qualification	Validated for −40 °C to +150 °C junction temperature - enables use in engine bay and transmission control units.
Dual-mode slew control	Hardware-selectable via ASC pin - eliminates need for firmware configuration or external resistors in production designs.
Integrated short-circuit shutdown	Auto-disable within 10 μs and current limit ≤150 mA - avoids fuse blowing and protects upstream power rails.
Wide common-mode input range	−2 V to VS+3 V - accommodates ground potential differences across distributed vehicle ECUs without signal loss.
Buffered reference output (RX1)	0.5×VS ±5%, 2–9 kΩ output impedance - enables accurate external comparator-based bus fault detection.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TJA1042T/3	Lower supply current (dominant: 45 mA vs. 80 mA); no buffered reference output (RX1); identical SO-8 package.	Lacks RX1 reference for external diagnostics; better suited for low-power body nodes where reference monitoring is not required.	Choose when minimizing quiescent current is prioritized over integrated diagnostic capability.
SN65HVD230DR	Non-AEC-Q100; wider common-mode range (−12 V to +12 V); no short-circuit shutdown; 3.3 V supply only.	Not qualified for automotive under-hood use; suitable only for industrial CAN networks with stable 3.3 V rails and no load-dump exposure.	Choose only for non-automotive applications requiring extended common-mode range without automotive qualification.

Compared with TJA1042T/3 and SN65HVD230DR, the L9616-TR uniquely combines AEC-Q100 Grade 0, integrated short-circuit shutdown, and a buffered reference output - making it the only option among the three qualified for safety-critical, high-transient automotive domains requiring diagnostic readiness.

FAQ

What is the function of the ASC pin on the L9616-TR?

The ASC (Adjustable Slope Control) pin selects the transmitter slew rate: grounding ASC enables high-speed mode (≤1 Mbaud, 20–50 V/μs), while connecting ASC to VS enables low-speed mode (≤250 kbaud, 5–20 V/μs) to reduce electromagnetic interference. This hardware-selectable feature eliminates firmware dependency and simplifies layout for EMI-sensitive applications.

Does the L9616-TR support fault-tolerant CAN (ISO 11898-3)?

No - the L9616-TR complies with ISO/DIS 11898-2 (high-speed CAN), not ISO 11898-3 (fault-tolerant low-speed CAN). It operates at up to 1 Mbaud with differential signaling on C_H/C_L, requires termination resistors, and lacks the single-wire fallback mode or asymmetric voltage thresholds of fault-tolerant transceivers.

Can the L9616-TR operate with a 3.3 V CAN controller?

Yes - the TXO input accepts 0.7×VS high-level and 0.3×VS low-level thresholds, and VS is 4.5–5.5 V. A 3.3 V controller driving TXO meets these levels when VS = 5 V (0.7×5 = 3.5 V > 3.3 V, but margin is acceptable per test condition data showing functional operation down to 0.7 VS min). RXO output swings rail-to-rail (0.9 VS high, 0.5 V low), compatible with 3.3 V controller inputs.

What is the purpose of the RX1 pin?

RX1 provides a buffered 0.5×VS reference voltage (±5%) with 2–9 kΩ output impedance. It serves as a stable bias point for external comparators used in bus fault detection, common-mode monitoring, or diagnostic circuits - enabling precise measurement of bus asymmetry or open-wire conditions without loading the internal regulator.
