概要
Description
TCAN1042HGDRQ1 is a Texas Instruments automotive-grade high-speed CAN transceiver. It sits between a CAN controller and the physical CAN bus, converting TXD (controller → bus) into CANH/CANL and providing RXD (bus → controller) data back to the controller.
Key points:
- Supports classic CAN (CAN 2.0A/B) communication on the bus.
- Interfaces: TXD/RXD for the controller, CANH/CANL for the bus, plus power and protection features.
- Robust automotive protections: undervoltage/overvoltage, short-to-GND or short-to-CANH/ CANL, ESD, and fault monitoring with fail-safe outputs.
- Power-conscious: designed for automotive environments with standby/low-power modes.
- Package variant HGDRQ1 indicates a specific TI packaging/tape-and-reel option.
Common uses: automotive ECUs, gateways, body-control modules, and other applications needing a reliable CAN physical layer interface.
For exact electrical specs (voltage ranges, timing, current draw, fault thresholds) and the precise package/pinout, refer to the TCAN1042HGDRQ1 datasheet on TI’s website.
