Product details
Overview
TCAN11623DMTRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive CAN FD System Basis Chip (SBC) integrating a 3.3V/70mA LDO (VLDO3), high-speed CAN transceiver (up to 8 Mbps), VIO level shifting (1.7V–5.5V), and ultra-low-power sleep mode. It provides bus fault tolerance (±58V), load dump protection, and INH-controlled system power gating for ADAS and body electronics.
For engineers reviewing the TCAN11623DMTRQ1 datasheet, TCAN11623DMTRQ1 pinout, TCAN11623DMTRQ1 application, or TCAN11623DMTRQ1 equivalent, key selection criteria include its 3.3V LDO output capability, sleep-mode supply current of 40 µA (≤85°C), ±58V bus fault tolerance, and VSON-14 wettable flank package for AOI-compatible automotive PCB assembly.
Technical Context
The TCAN11623DMTRQ1 implements a dual-mode CAN physical layer supporting both classical CAN and CAN FD up to 8 Mbps with integrated bus biasing control and dominant timeout (TXD DTO). Its architecture includes autonomous bus monitoring in sleep mode via a dedicated wake-up receiver compliant with ISO 11898-2:2016 WUP detection.
Power management is handled through three distinct operating modes: normal (full transceiver active), standby (low-power wake-up receiver enabled), and sleep (INH gated, only SBC powered). The 3.3V VLDO3 output is derived from an internal 5V LDO stage and supports external loads up to 70 mA with ±50 mV load regulation.
Key Specifications

|---|---|
| CAN Data Rate | Up to 8 Mbps - enables high-bandwidth CAN FD communication for ADAS sensor fusion and ECU coordination. |
| LDO Output | 3.3V / 70 mA (VLDO3) - powers external microcontrollers or peripherals without requiring a separate regulator. |
| Sleep Current | 40 µA at TA ≤ 85°C - sustains ultra-low-power bus monitoring while minimizing battery drain in parked vehicles. |
| Bus Fault Tolerance | ±58V on CANH/CANL - ensures robust operation during load dump, jump-start, or ESD events in 12V/24V automotive systems. |
| Operating Voltage | VSUP = 5.5V–28V - compatible with wide-range automotive battery supplies including cold-crank conditions. |
| VIO Range | 1.7V–5.5V - allows direct interface to 1.8V, 2.5V, 3.3V, or 5V host controllers without external level shifters. |

Pinout & Package
TCAN11623DMTRQ1 uses the leadless VSON-14 (DMT) package (4.5 mm × 3 mm) with exposed thermal pad electrically connected to GND. Wettable flanks enable reliable AOI-based solder joint inspection in automotive manufacturing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXD | Digital input | CAN transmit data input with integrated 40–80 kΩ pull-up; accepts 1.7V–5.5V logic levels via VIO. |
| GND | Ground reference | Primary ground connection; thermal pad must be soldered to PCB ground plane for thermal relief. |
| VFLT | 5V LDO filter | Filter pin for internal 5V LDO; requires 10 µF capacitor to GND for stability and noise suppression. |
| RXD | Digital output | CAN receive data output, tri-stated when VIO falls below UVVIO (1.25V typical). |
| VIO | IO supply voltage | Defines logic level thresholds for TXD, RXD, nSLP, and TS; supports 1.7V–5.5V interface voltages. |
| TS | Transceiver status | Open-drain output indicating transceiver activity state (high = active, low = standby/sleep). |
| INH | High-voltage inhibit | Open-drain high-voltage output (up to 42V) to control external regulators; drives high on wake-up. |
| VLDO3 | 3.3V LDO output | Regulated 3.3V supply (±50 mV line/load regulation) capable of sourcing 70 mA to external circuitry. |
| WAKE | Local wake input | High-voltage wake pin (4V VIH min) enabling local wake-up events independent of CAN bus activity. |
| VSUP | Main supply input | High-voltage battery input (5.5V–28V); includes ±42V absolute max rating and load dump protection. |
| nRST | Bidirectional reset | Reset input/output with internal pull-up to VLDO3; asserts cold-crank pulse (20–27 ms) on undervoltage. |
| CANL / CANH | CAN bus IO | Differential bus terminals with ±58V fault tolerance, 20 pF input capacitance, and 50–100 kΩ differential resistance. |
| nSLP | Sleep mode control | Active-low digital input with integrated 40–80 kΩ pull-down; 35 µs minimum low pulse to enter sleep mode. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD SBC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN11625DMTRQ1 | 5V/100mA LDO (VCCOUT) instead of 3.3V/70mA (VLDO3); identical pinout and functional modes. | Used where external 5V peripherals require local regulation; not suitable when 3.3V MCU supply is primary requirement. | Select TCAN11625DMTRQ1 only if system design mandates 5V LDO output; otherwise TCAN11623DMTRQ1 minimizes voltage conversion losses. |
| TCAN1042DRQ1 | Standalone CAN transceiver (no LDO, no INH, no sleep mode); SOIC-8 package; lower integration level. | Requires external LDO, reset supervisor, and power controller; higher BOM cost and board area vs. SBC solution. | Choose TCAN1042DRQ1 only for cost-sensitive non-sleep applications or when existing power architecture precludes SBC adoption. |
Compared with TCAN11625DMTRQ1, TCAN11623DMTRQ1 delivers optimized 3.3V supply efficiency for modern low-voltage MCUs, while TCAN1042DRQ1 lacks integrated power management-making TCAN11623DMTRQ1 the only option that simultaneously satisfies 3.3V regulation, ultra-low sleep current, and automotive-grade protection in one package.

FAQ
What is the maximum CAN FD data rate supported by TCAN11623DMTRQ1?
The TCAN11623DMTRQ1 supports CAN FD up to 8 Mbps, verified per ISO 11898-2:2016. This rate is achievable under recommended operating conditions (VSUP = 12 V, VIO = 3.3 V, RL = 60 Ω, CL = 100 pF), with loop delay (TXD→RXD) maintained at ≤175 ns for dominant-to-recessive transitions. TCAN11623DMTRQ1 maintains timing symmetry (ΔtREC ≤ ±40 ns) at this rate, ensuring deterministic communication in time-critical ADAS applications.
Does TCAN11623DMTRQ1 provide a regulated 3.3V output, and what is its current capability?
Yes, TCAN11623DMTRQ1 integrates a dedicated 3.3V LDO (VLDO3) capable of delivering up to 70 mA to external circuitry. Its output voltage is specified at 3.2V–3.4V across load (1–70 mA) and input (5.5V–18V) variations, with ±50 mV load regulation and ±50 mV line regulation. This eliminates the need for an external 3.3V regulator in designs using 3.3V microcontrollers or sensors, directly supported by the TCAN11623DMTRQ1 VLDO3 pin.
How does TCAN11623DMTRQ1 achieve ultra-low-power sleep mode, and what is its typical current draw?
TCAN11623DMTRQ1 achieves ultra-low-power sleep mode by disabling the high-speed transceiver, gating the INH output to shut down external regulators, and retaining only the wake-up receiver and internal bias circuits. At ambient temperature ≤85°C, its supply current (ISUP(SLP)) is 40 µA; at >85°C, it rises to 50 µA. This enables multi-year battery operation in parked-vehicle scenarios while maintaining full wake-on-CAN or WAKE pin responsiveness-verified in TCAN11623DMTRQ1 characterization data.
What protection features does TCAN11623DMTRQ1 include for automotive environments?
TCAN11623DMTRQ1 includes ±58V bus fault tolerance on CANH/CANL, load dump protection on VSUP (up to 42V), IEC 61000-4-2 ±8 kV contact ESD on CAN terminals, ISO 7637-2 Pulse 1/2/3a/b transient immunity, thermal shutdown (175°C rising), TXD dominant timeout (1.2–3.8 ms), and undervoltage/overvoltage detection on all supply rails. These protections are validated per AEC-Q100 Grade 1 and ISO 16750-2, making TCAN11623DMTRQ1 suitable for harsh automotive under-hood and chassis locations.
Is TCAN11623DMTRQ1 pin-compatible with other devices in the TCAN1162x-Q1 family?
Yes, TCAN11623DMTRQ1 is pin-compatible with TCAN11625DMTRQ1 in the VSON-14 (DMT) package. Both share identical pin assignments, mechanical footprint, and functional pin behavior-including TXD, RXD, nSLP, WAKE, INH, VSUP, CANH, CANL, and VIO. The only difference is the LDO output: TCAN11623DMTRQ1 provides VLDO3 (3.3V/70mA), while TCAN11625DMTRQ1 provides VCCOUT (5V/100mA). This allows direct substitution where voltage rail requirements align, confirmed in TI's official pinout documentation for TCAN11623DMTRQ1.
