概述

Description

The SN65HVD1780QDRQ1 is TI’s high‑speed CAN transceiver that sits between a CAN controller and the CAN bus. It translates logic TXD/RXD signals to CANH/CANL differential bus signals and vice versa, enabling CAN 2.0B communication.
Key points:
- Interfaces: TXD input from the controller, RXD to the MCU, CANH/CANL to the CAN bus.
- Performance: Supports CAN data rates up to about 1 Mbps; operates from a single 4.5–5.5 V supply.
- Protections: Undervoltage, short‑circuit/overcurrent protection, thermal shutdown, and fault/diagnostic behavior for robust automotive use.
- Fault handling: Failsafe RXD output defined when the bus is idle or in fault conditions.
- Package: QDRQ1 (compact 8‑pin) suitable for automotive ECUs and space‑constrained designs.
Applications: Automotive and industrial networks requiring a robust, isolated link between a CAN controller and the CAN bus.

Features

Here are key features of the SN65HVD1780QDRQ1 (CAN transceiver):
- High-speed CAN transceiver for CAN 2.0B, up to 1 Mbps
- Differential CANH/CANL driver and receiver
- Single-supply operation: 4.5 V to 5.5 V
- Sleep/low-power standby mode
- Robust protection: undervoltage/overvoltage, short to GND or battery on the bus
- Slew-rate control for EMI reduction
- Fail-safe/open-wire detection with dominant/recessive state indication
- ESD protection on CAN pins
- Wide operating temperature range; automotive-grade option available (AEC-Q100 qualified) depending on package/grade
- Typical package options for automotive designs (pin-compatible options)
Notes: exact package, temp range, and qualification depend on the specific variant (QDRQ1). For precise specs, refer to the TI datasheet.

Package

8-pin HTSSOP package (automotive-grade Q1 variant).

Pinout

- Pin count: 8 pins in the QFN (QDRQ1) package.
- Function: High-speed CAN transceiver that interfaces a CAN controller (TXD/RXD) to the CAN bus (CANH/CANL); provides VCC and GND and includes enable/standby control pins.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- Company type: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits (ICs), microcontrollers, sensors, and related products for automotive, industrial, and consumer markets.

Application

Primarily an RS-485/RS-422 transceiver used in industrial and building automation. Suitable for long-distance, multi-drop serial links in noisy or harsh environments. Typical applications include PLCs and motor-drive controllers, factory automation and process control, energy metering and telemetry, data acquisition and remote sensing, HVAC and building-management networks, and other microcontroller-based RS-485/RS-422 communications.

Equivalent

Equivalent high‑speed CAN transceivers (1 Mb/s) from other vendors:
- NXP: TJA1040, TJA1041; PCA82C250
- Microchip: MCP2561, MCP2562
- STMicroelectronics: L9616, L9617
Note: check voltage, pinout, standby/fault, and slope/ESD features to ensure true compatibility.
