The TCAN843-Q1 is a high-speed Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2024 high-speed CAN specification. The device supports both classical CAN and CAN FD data rates up to 5 megabits per second (Mbps).

The TCAN843-Q1 allows for system-level reductions in battery current consumption by selectively enabling the various power supplies that can be present on a system via the INH output pin. This allows a low-current sleep state in which power is gated to all system components except for the TCAN843-Q1, while monitoring the CAN bus. When a wake-up event is detected, the TCAN843-Q1 initiates system start-up by driving INH high.

TCAN-SOIC14-EVM — 通用 SOIC 14 針腳 CAN 評估模組

通用 SOIC 14 針腳 CAN 評估模組 (EVM) 為使用者提供評估所有 TI 14 針腳 CAN 收發器系列的能力。這款通用 14 針腳 CAN EVM 可透過填充收發器並在 EVM 上設定跨接器進行配置，並搭配所有 TI 14 針腳 CAN 收發器系列使用。

此 EVM 也具備 SIC 網路的配置面積，可透過使用者安裝的 J10 和 J11 連接至 CAN 匯流排線路。將 SIC 網路連接至 CANH 和 CANL 會在訊號中增加更多反射和振鈴，以模擬有雜訊的 CAN 匯流排。這可用於在雜訊較高的環境中測試收發器的可靠性。
