TCAN1042HVDRBRQ1

TCAN1042HVDRBRQ1 is Texas Instruments’ high‑voltage CAN transceiver designed for automotive networks. It sits between a CAN controller and the CAN bus, converting the controller’s TXD into differential CANH/CANL signals and feeding RXD back to the controller.
Key points:
- Wide automotive supply range with protections (undervoltage/overcurrent, fault protection on CANH/CANL, ESD, thermal protection).
- TTL/CMOS‑compatible TXD/RXD interface to the CAN controller; CANH/CANL pins drive the bus.
- Intended for automotive applications such as ECUs, gateways, and body networks that require robust bus protection.
Package/availability:
- DRBRQ1 denotes the specific TI packaging (D‑package, reel). See the datasheet for exact pinout and electrical specs.
For exact electrical characteristics, timing, and wiring guidelines, consult the TI product page and datasheet.

Direct cross-reference depends on packaging and bus voltage. Reasonably equivalent high-voltage CAN transceivers include:
- NXP TJA1042 (and TJA1040)
- STMicroelectronics L9616/L9617
- Microchip MCP2561/MCP2562
- TI SN65HVD230/232/234
Note: verify HV tolerance, pinout, and features (Standby/fault) before substituting.

Here are the main features of the TCAN1042HVDRBRQ1 (highlights from the TCAN1042HV family):
- High-speed CAN transceiver, data rate up to 2 Mbps.
- Automotive-grade, wide-voltage/ HV-tolerant design suitable for 12V/24V automotive networks.
- Bus fault protection and transient immunity on CANH/CANL, with protection against voltage surges on the bus.
- Slew-rate control on CANH/CANL to reduce EMI.
- Sleep/standby mode with low quiescent current; wake-up on CAN activity.
- Enable/Disable (EN) control for easy power management and silent operation when needed.
- Fault detection features (short to GND/VCC, open-wire) and robust protection against over/undervoltage.
- Undervoltage lockout, thermal shutdown and protection for reliable operation.
- ESD and fault protection suitable for automotive environments.
- Operating temperature typically -40°C to 125°C and RoHS-compliant.
Note: For exact electrical specs (voltages, currents, protections) refer to the TI datasheet for TCAN1042HV.

Pin count: 8 pins.
Function: High-voltage CAN transceiver that interfaces a CAN controller to the CAN bus. Pins include CANH and CANL (bus), TXD (controller input), RXD (controller output), VCC and GND (power), and control pins EN (enable) and STB (standby).
