Typical Applications
SN65HVD230QDRQ1 is suitable for 6 applications: Automotive Body Electronics and Gateways, Battery Management Systems, Industrial Automation Networks, Medical and Diagnostic Equipment, Elevators, HVAC, and Building Control, 3.3-V DSP-Based Motor Control.
Automotive Body Electronics and Gateways
In body control modules, door nodes, lighting modules, and central gateways, the SN65HVD230QDRQ1 bridges 3.3-V MCUs to the ISO 11898-2 CAN bus without level shifting. Its AEC-Q100 qualification, -40C to +125C range, and customer-specific configuration control satisfy automotive release requirements. The 370 uA standby mode supports KL30 sleep budgets, while 15 kV HBM bus ESD protection and an unpowered-node-quiet behavior improve robustness at the assembly plant and in the field.
Recommended
Battery Management Systems
BMS slave boards increasingly run 3.3-V MCUs, making a 3.3-V CAN transceiver a natural fit. The SN65HVD230QDRQ1's 370 uA typical standby current protects the sleep budget of the pack, and its 1 Mbps rate supports fast cell-balancing telemetry. Because a de-energized BMS node does not disturb the bus, pack disconnect events do not stall network communication between remaining modules.
Recommended
Industrial Automation Networks
Factory automation nodes, motor drives, and PLC remote I/O use CANopen or CAN-based fieldbuses where 3.3-V controllers are now common. The device's controlled driver output transition times (settable via the RS pin resistor) reduce ringing on long STP cabling, improving EMC margins in electrically noisy cabinets. ISO 11898-2 compatibility ensures interoperability with legacy 5-V nodes already installed on the same segment.
Recommended
Medical and Diagnostic Equipment
Portable analyzers, infusion systems, and diagnostic carts often network several boards over CAN from a single 3.3-V logic domain. The transceiver's low 3.3-V supply simplifies single-rail designs, the 370 uA standby current extends battery operating time between charges, and the 15 kV HBM bus ESD rating protects against patient-adjacent handling and cable transients during cleaning and transport.
Recommended
Elevators, HVAC, and Building Control
Building control segments (elevator controllers, air handling units, fire panels) use CAN for inter-board communication over long cable runs. The SN65HVD230QDRQ1's dominant-timeout and unpowered-node behavior keep the bus usable when individual controller boards lose power, while RS-pin slope control helps meet EMC emission limits on long unshielded runs typical of building installations.
Recommended
3.3-V DSP-Based Motor Control
The SN65HVD230Q family was originally designed for TI TMS320Lx240x 3.3-V DSPs with on-chip CAN controllers, and remains an excellent pairing for C2000-class motor-control MCUs. Direct 3.3-V TXD/RXD connection eliminates level translators, and the 1 Mbps rate supports high-frequency torque-loop supervision messages in multi-drive CAN networks without protocol degradation.

Key Differentiators
- AEC-Q100 automotive qualification with configuration control (vs SN65HVD230DR)
- 370 uA typical standby current (vs SN65HVD232QDRQ1)
- True 3.3-V single-supply operation (vs TJA1051T/3/1)
Design Notes
Place a 100 nF ceramic decoupling capacitor within 2 mm of the VCC pin (pin 3) with a solid via to the ground plane. Route CANH and CANL as a tightly coupled 120-ohm differential pair, keeping stubs to the connector shorter than a few centimeters at 1 Mbps. Keep the RS trace short and quiet since it sets the driver slope; a long trace can couple noise into the mode-selection threshold.
The most frequent design error is leaving the RS pin floating. Tie it to ground for high-speed 1 Mbps operation, use a resistor to ground for slope control on slower or EMC-sensitive networks, or drive it from the MCU to enter the 370 uA standby mode. Note that in standby the receiver output is limited; the controller must handle wake-up sequences per the TI datasheet. Also confirm your CAN controller outputs 3.3-V logic if considering 5-V cross-brand alternatives.
The SOIC-8 package dissipates modest power at 3.3 V, but worst case occurs with repeated dominant transmission at 1 Mbps and a bus fault driving full load current. Estimate P = VCC x ICC(dominant) plus bus-load contribution, and verify junction temperature stays below 125C ambient-max designs by using at least 4-6 vias to internal ground planes under pin 2 for heat spreading. For most 3.3-V nodes no heatsinking is needed.
