Product details
Overview
TCAN1463DRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive CAN FD transceiver supporting data rates up to 8 Mbps, featuring Signal Improvement Capability (SIC) per CiA 601-4, ±58-V bus fault tolerance, and low-power sleep mode with INH-controlled system power gating. It operates across 4.5–40 V VSUP and supports 1.7–5.5 V VIO level shifting for MCU interface flexibility in body electronics and ADAS gateways.
For engineers reviewing the TCAN1463DRQ1 datasheet, TCAN1463DRQ1 pinout, TCAN1463DRQ1 application, or TCAN1463DRQ1 equivalent, this page delivers verified electrical specs, SIC-enabled timing behavior, validated sleep/wake transition parameters, real-world bus fault protection limits, and confirmed package-specific thermal metrics - all directly traceable to TI's production-grade SLLSFE5C datasheet.
Technical Context
The TCAN1463DRQ1 implements a dual-stage CAN physical layer driver with active SIC circuitry that reduces dominant-to-recessive ringing and improves bit symmetry by dynamically adjusting bus biasing during signal transitions. Its integrated SWE timer enforces safe 4-minute hardware timeout from Standby to Sleep mode upon inactivity, independent of MCU control.
It features four distinct operating modes - Normal, Silent, Standby, and Sleep - each with rigorously specified supply currents (e.g., 18–30 µA in Sleep mode), defined undervoltage thresholds (UVSUP(R): 3.85–4.4 V), and precise wake-up timing (tWK(FILTER): 0.5–1.8 µs). The INH_MASK pin enables deterministic disabling of the high-voltage INH output during spurious events without requiring external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN Data Rate | Up to 8 Mbps - enables full CAN FD throughput in large networks with multiple unterminated stubs |
| Signal Improvement (SIC) | Actively eliminates ringing and enhances bit symmetry per CiA 601-4 - improves timing margin at 2/5/8 Mbps |
| Bus Fault Tolerance | ±58 V - protects against load dump, battery reversal, and ESD-coupled transients on CANH/CANL |
| Sleep Mode Current | 18–30 µA - enables ultra-low-power always-on bus monitoring with autonomous wake-up via WAKE or bus activity |
| VIO Level Shifting | 1.7–5.5 V - allows direct interfacing with 1.8 V, 2.5 V, 3.3 V, or 5 V MCUs without external level shifters |
| INH Output Drive | High-voltage open-drain output - directly controls external 5–40 V system regulators (e.g., buck converters) for power sequencing |
| Thermal Shutdown | 175 °C trip / 160 °C release - provides fail-safe protection under sustained overload or poor PCB heatsinking |
Pinout & Package
TCAN1463DRQ1 is available in SOIC (D), SOT (DYY), and VSON (DMT) packages - all 14-pin, leaded or wettable-flank variants optimized for automotive AOI and thermal reliability. Package dimensions: SOIC 8.65 × 3.90 mm, SOT 4.20 × 2.00 mm, VSON 4.50 × 3.00 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXD | CAN transmit data input | CMOS-level input with internal 40–80 kΩ pull-up to VIO - accepts standard MCU TX output without external bias |
| RXD | CAN receive data output | Tri-state CMOS output active only when VIO > UVIO - prevents bus contention during MCU power-down |
| CANH / CANL | Differential CAN bus I/O | High-voltage, ±58 V tolerant differential pair with 30–100 kΩ input resistance - immune to common-mode noise up to ±12 V |
| VSUP | Main battery supply input | 4.5–40 V input with load-dump support up to 45 V/300 ms - powers internal regulator and INH driver |
| INH | System power inhibit output | Open-drain high-voltage output (up to VSUP) - directly enables/disables external DC/DC converters for system-wide power gating |
| WAKE | Local wake-up input | High-voltage wake pin (VSUP − 3.5 V threshold) - triggers wake from Sleep/Standby without CAN bus activity |
| nSTB | Standby mode control | Active-low input with internal 40–80 kΩ pull-down - selects Standby/Sleep mode; floating = Normal mode |
| INH_MASK | INH enable/disable control | Active-high input with internal pull-down - disables INH output during spurious wake events; leave floating or tie to GND if unused |
Key Features
| Feature | Design Value |
|---|---|
| Signal Improvement Capability (SIC) | Reduces dominant-to-recessive ringing and improves bit symmetry - enables reliable 5–8 Mbps operation in electrically noisy, multi-node automotive networks |
| Sleep Wake Error (SWE) Timer | Hardware-enforced 4-minute timeout from Standby to Sleep - ensures safe low-power state entry even after MCU software failure or power interruption |
| INH-Masked Wake Control | INH_MASK pin prevents false system power-up during transient noise on WAKE - eliminates need for external RC filtering or firmware debouncing |
| Unpowered Bus Isolation | High-impedance CANH/CANL and IO pins when VSUP = 0 V - prevents loading of live CAN bus or MCU I/O during board power-off |
| IEC & ISO Transient Protection | Withstands ±8 kV contact ESD (ISO 10605), ±15 kV air discharge, and ISO 7637-2 Pulse 1/2/3a/3b transients - meets OEM EMC requirements out-of-box |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN1043A-Q1 | No SIC; lower max data rate (5 Mbps); no INH output; no SWE timer; lacks INH_MASK pin | Suitable for cost-sensitive, non-gateway nodes where 5 Mbps suffices and system power control is handled externally | Select TCAN1043A-Q1 only if SIC, INH-driven power gating, or guaranteed Sleep transition are not required |
| TCAN1145-Q1 | Includes SIC and INH, but no INH_MASK; higher sleep current (45 µA vs. 30 µA); no WAKE pin - wake only via bus activity | Better for simple wake-from-bus designs; less suitable for systems requiring local hardware wake sources (e.g., PIR sensors) | Choose TCAN1145-Q1 when local WAKE input and sub-30 µA sleep are unnecessary, and INH_MASK is not needed |
Compared with TCAN1043A-Q1 and TCAN1145-Q1, TCAN1463DRQ1 uniquely integrates SIC, INH_MASK, WAKE pin, and SWE timer - delivering superior signal integrity, deterministic power sequencing, and robust wake control for next-gen automotive domain controllers.

FAQ
What is the maximum CAN FD data rate supported by the TCAN1463DRQ1?
The TCAN1463DRQ1 supports CAN FD data rates up to 8 Mbps, verified across temperature (−40°C to 150°C) and supply voltage (4.5–40 V). This capability is enabled by its integrated Signal Improvement Capability (SIC), which maintains signal integrity at high speeds in electrically challenging automotive networks with multiple unterminated stubs. The TCAN1463DRQ1 achieves this while meeting ISO 11898-2:2016 and CiA 601-4 specifications.
Does the TCAN1463DRQ1 support level shifting between different I/O voltages?
Yes, the TCAN1463DRQ1 supports VIO level shifting from 1.7 V to 5.5 V, allowing direct interface with MCUs operating at 1.8 V, 2.5 V, 3.3 V, or 5 V logic levels. The RXD output is tri-state when VIO falls below its undervoltage threshold (UVIO), and TXD includes an internal pull-up to VIO. This eliminates external level-shifting components in mixed-voltage automotive systems using the TCAN1463DRQ1.
How does the INH output function in system power management with the TCAN1463DRQ1?
The INH output of the TCAN1463DRQ1 is a high-voltage open-drain pin capable of driving external 5–40 V system regulators. When asserted high, it enables downstream power supplies; when low or floating, it disables them. This allows the TCAN1463DRQ1 to gate power to entire subsystems during Sleep mode, reducing total system quiescent current. The INH_MASK pin provides hardware-level control to prevent spurious activation - a key feature not found in most competing transceivers like the TCAN1043A-Q1.
What protection features does the TCAN1463DRQ1 include for automotive environments?
The TCAN1463DRQ1 includes ±58-V CAN bus fault tolerance, load-dump support up to 45 V for 300 ms on VSUP, IEC 61000-4-2 ±8-kV contact/±15-kV air ESD protection on CANH/CANL/VSUP/WAKE, ISO 7637-2 Pulse 1/2/3a/3b transient immunity, undervoltage lockout on VSUP/VCC/VIO, thermal shutdown (175°C trip), and TXD dominant timeout. These protections are fully characterized and documented in TI's SLLSFE5C datasheet for the TCAN1463DRQ1.
Is the TCAN1463DRQ1 pin-compatible with other TI CAN transceivers?
The TCAN1463DRQ1 is pin-compatible with TCAN1043A-Q1 and TCAN1043-Q1 when the INH_MASK pin is left floating or tied to GND (i.e., INH_MASK functionality disabled). All share identical 14-pin SOIC (D), SOT (DYY), and VSON (DMT) footprints and core signal mapping (TXD, RXD, CANH, CANL, VSUP, etc.). However, TCAN1463DRQ1 adds INH, WAKE, and INH_MASK pins - unused pins in legacy designs can remain unconnected without impact.
