Description
TCAN1043GDMTRQ1 is Texas Instruments’ single-channel CAN transceiver in the TCAN1043 family. It sits between a CAN controller and the CAN bus, converting the controller’s TXD into differential CANH/CANL signals and translating the bus state back to RXD for the controller. It provides a robust physical layer with protection features such as undervoltage/overvoltage protection, short‑circuit protection on the bus pins, thermal shutdown, and ESD protection, plus a low‑power standby mode. The device supports standard CAN operation up to about 1 Mbps and offers a wide bus common‑mode range suitable for automotive and industrial networks. The GDMTRQ1 suffix identifies a specific package/config variant. Typical applications include automotive ECUs, instrument clusters, and industrial CAN endpoints requiring reliable fault protection and low power. For exact electrical specifications, pinout, timing, and qualification details, refer to the TI TCAN1043 datasheet and product page.
