It features three operating modes: Normal, Standby, and Sleep. In Sleep mode, VCC and VIO can be powered down while the device monitors the CAN bus via an internal low-power receiver; when a wake-up pattern is detected on the bus or via the local WAKE pin, the INH output drives high to enable the external voltage regulator, initiating node start-up. A separate VIO pin supports 2.8V to 5.5V logic levels, enabling direct 3.3V MCU interfacing without level translation.","working_principle":"The TCAN1043DMTRQ1 converts between MCU logic levels (VIO-referenced) and CAN bus differential signal levels. In Normal mode, it operates as a standard CAN transceiver with optimized symmetric bus outputs for minimal EMI. In Standby mode, the driver is disabled and a low-power receiver monitors the bus for a valid wake-up pattern; RXD asserts low when a wake-up is detected. In Sleep mode, all internal circuitry is powered down except the wake detection logic, drawing less than 15 uA. The INH pin is an open-drain output that drives an external voltage regulator enable pin; it is active in Normal and Standby modes, and deasserted in Sleep mode until a wake event occurs. The VIO terminal provides internal logic level translation, allowing TXD, RXD, and STB pins to operate at 3.3V while VCC is 5V.","pin_description":"
