TCAN2451RHBRQ1

The TCAN2451RHBRQ1 is TI’s high‑speed CAN transceiver. It sits between a CAN controller (TXD/RXD) and the CAN bus (CANH/CANL) and supports ISO 11898-2 communication. Key features include a single 4.5–5.5 V supply, standby/low-power mode, fault protection (over-voltage, short to bus, undervoltage, thermal), and ESD protection. The RHBRQ1 suffix indicates the device’s packaging/RoHS options (verify exact package in the TI datasheet). Typical use is automotive and industrial CAN networks, where the MCU handles protocol/frames and the transceiver drives the bus. Pins commonly include VCC, GND, CANH, CANL, TXD, RXD, and STB/EN. In a design, connect TXD to the CAN controller, RXD to the controller’s receive line, CANH/CANL to the bus, and use STB to enter low-power mode as needed.

Here are the main features of TCAN2451RHBRQ1 (CAN transceiver, TI):
- Automotive-grade CAN transceiver for CAN 2.0 A/B (classic CAN); data rates up to 1 Mbps.
- Single 5-V supply; TXD/RXD interface compatible with 3.3-V logic levels.
- Bus pins CANH and CANL with robust protection: bus fault protection (high-voltage/transient suppression) and ESD protection.
- Short-circuit and overvoltage protection on CANH/L; current limiting and fault-recovery behavior.
- Low quiescent current with low-power/standby mode for sleep power savings.
- Fail-safe RXD output (indicates bus state under fault or power-down conditions).
- Undervoltage and thermal monitoring for protection.
- Wide operating temperature range suitable for automotive (-40°C to 125°C).
- Packaging: RHBRQ1 option (industrial/automotive package variant).
