Product details
Overview
SN65HVD231QDRG4Q1 from Texas Instruments is an AEC-Q100 qualified 3.3-V automotive CAN transceiver with integrated slope control and sleep mode. It provides differential transmit/receive capability compliant with ISO 11898, supports signaling rates up to 1 Mbps, features 0.1 µA typical sleep current, −2 V to 7 V bus common-mode range, and 15-kV HBM ESD protection on CANH/CANL - deployed in automotive ECUs for engine control and body electronics.
For engineers reviewing the SN65HVD231QDRG4Q1 datasheet, SN65HVD231QDRG4Q1 pinout, SN65HVD231QDRG4Q1 application, or SN65HVD231QDRG4Q1 equivalent, key selection criteria include low-power sleep mode activation via RS pin, differential output voltage (VOD) ≥1.2 V dominant, thermal shutdown protection, fail-safe open-circuit receiver behavior, and compatibility with TMS320Lx240x DSPs.
Technical Context
The SN65HVD231QDRG4Q1 implements a fully differential physical-layer interface between a 3.3-V CAN controller and the CAN bus, featuring independent driver and receiver shutdown in sleep mode when RS > 0.75 VCC. Its receiver includes hysteresis (100 mV) and failsafe logic that outputs high when CANH/CANL are open.
Driver output transition times are programmable via external resistor on RS (10 kΩ → ~15 V/µs; 100 kΩ → ~2 V/µs), enabling EMI optimization without hardware change. Total loop delay ranges from 70 ns (high-speed) to 920 ns (max slope control), supporting both high-speed industrial and noise-sensitive automotive networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - Enables direct integration with 3.3-V microcontrollers and DSPs without level-shifting. |
| Signaling Rate | Up to 1 Mbps - Meets ISO 11898 high-speed CAN requirements for real-time vehicle communication. |
| Sleep Current | 0.1 µA typical - Allows battery-powered modules (e.g., door modules, sensors) to remain CAN-connected for wake-on-bus events. |
| Differential Output Voltage (Dominant) | 1.2–3.0 V - Ensures robust signal margin (>0.9 V threshold) across temperature and load variations. |
| Common-Mode Range | −2 V to +7 V - Withstands automotive load-dump and ground-shift transients without bus lockup. |
| ESD Protection (CANH/CANL) | ±15 kV HBM - Eliminates need for external TVS diodes in most automotive PCB layouts. |
| Receiver Threshold Hysteresis | 100 mV - Prevents chatter during slow-rising bus edges or noisy environments. |
Pinout & Package
SN65HVD231QDRG4Q1 uses an SOIC-8 (D) package with 150-mil width, RoHS-compliant, moisture sensitivity level 2a, and tape-and-reel packaging (suffix R).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D | Driver input | CMOS-compatible TTL-level input from CAN controller TX; accepts 0–3.6 V swing. |
| GND | Ground reference | Primary return path for supply and bus bias; must be low-impedance to minimize common-mode noise coupling. |
| VCC | Supply voltage | 3.3-V power input; requires local 100-nF ceramic decoupling adjacent to pin. |
| R | Receiver output | CMOS-compatible TTL-level output to CAN controller RX; drives standard logic inputs directly. |
| RS | Standby/slope control | Three-state control: <1 V = high-speed; 10–100 kΩ to GND = slope control; >0.75 VCC = sleep mode (driver + receiver off). |
| CANH | High bus terminal | Differential bus output; connects to twisted-pair CANH line; internally biased to VCC/2 in recessive state. |
| CANL | Low bus terminal | Differential bus output; connects to twisted-pair CANL line; complements CANH for differential signaling. |
| Vref | Voltage reference | Stable 1.65 V (VCC/2) output; used for external comparator bias or ADC reference in diagnostic circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C ambient), ensuring reliability in under-hood and chassis-mounted ECUs. |
| Sleep mode isolation | Both driver and receiver fully disabled in sleep; zero bus loading and sub-µA quiescent draw - critical for always-on gateways. |
| Failsafe receiver | Outputs logic high when CANH/CANL are open or shorted; prevents undefined controller states during wiring faults. |
| Thermal shutdown | Auto-disables bus drivers at junction temperature >165°C; recovers automatically after cooldown - protects against sustained overcurrent. |
| Hot-plug bus protection | Bus pins enter high-Z state during power-up/down or VCC < 2 V; eliminates bus glitches during module insertion or brownout. |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD230QDRQ1 | 370 µA standby current (driver off, receiver active); no sleep mode; same pinout and slope control. | Suitable where continuous bus monitoring is required during low-power states (e.g., gateway node listening for remote wake). | Select SN65HVD230QDRQ1 if receiver must remain active during low-power operation; SN65HVD231QDRG4Q1 preferred when full transceiver shutdown is needed. |

FAQ
What is the maximum signaling rate supported by the SN65HVD231QDRG4Q1?
The SN65HVD231QDRG4Q1 supports signaling rates up to 1 Mbps, as specified in the ISO 11898-2 standard. This is verified across the full operating temperature range (−40°C to +125°C) with typical propagation delays of 70–135 ns in high-speed mode. The SN65HVD231QDRG4Q1 maintains signal integrity at this rate due to controlled driver output transitions and receiver hysteresis.
How does the RS pin function in the SN65HVD231QDRG4Q1?
The RS pin on the SN65HVD231QDRG4Q1 controls three operating modes: logic low (<1 V) enables high-speed mode; connection to 10–100 kΩ resistor to ground enables slope control; logic high (>0.75 × VCC) activates sleep mode, disabling both driver and receiver. This dual functionality allows dynamic trade-offs between speed, EMI, and power consumption in the SN65HVD231QDRG4Q1.
Does the SN65HVD231QDRG4Q1 include fail-safe behavior for open-circuit bus conditions?
Yes. When CANH and CANL are open-circuited, the SN65HVD231QDRG4Q1 receiver outputs a logic high on pin R - a defined failsafe state preventing undefined MCU input. This behavior is guaranteed across temperature and supply voltage, and is implemented independently of RS pin state, ensuring reliability even in sleep mode.
What is the bus common-mode voltage range specification for the SN65HVD231QDRG4Q1?
The SN65HVD231QDRG4Q1 operates over a bus common-mode voltage range of −2 V to +7 V, exceeding ISO 11898 requirements. It withstands transient common-mode voltages of ±25 V (per Figure 7 test), enabling robust operation during automotive load-dump events and ground-shift conditions without bus lockup or damage.
Is the SN65HVD231QDRG4Q1 pin-compatible with other devices in the SN65HVD23xQ family?
Yes. The SN65HVD231QDRG4Q1 shares identical SOIC-8 (D) pinout with SN65HVD230QDRQ1 and SN65HVD232QDRQ1, allowing board-level interchangeability. However, functional differences exist: SN65HVD232Q lacks RS and Vref pins (NC), while SN65HVD230Q offers standby (not sleep) mode - so firmware and external circuitry must be validated per device.
