Q & A
- What is the TCAN1043A-Q1 used for?
The TCAN1043A-Q1 is a high-speed Controller Area Network (CAN) transceiver used in automotive and transportation applications to interface between the CAN bus and the CAN protocol controller.
- What are the supported CAN data rates for the TCAN1043A-Q1?
The TCAN1043A-Q1 supports both classical CAN and CAN FD data rates up to 8 megabits per second (Mbps).
- What are the operating modes of the TCAN1043A-Q1?
The device operates in Normal, Silent, Standby, and Low-power sleep modes.
- How does the TCAN1043A-Q1 manage power consumption?
The device allows for system-level reductions in battery current consumption by selectively enabling power supplies via the INH output pin and entering a low-current sleep state.
- What protection features does the TCAN1043A-Q1 offer?
The device includes protection features such as ±58-V CAN bus fault tolerance, load dump support, IEC ESD protection, under-voltage protection, thermal shutdown protection, and TXD dominant state timeout (TXD DTO).
- What is the purpose of the SWE timer in the TCAN1043A-Q1?
The Sleep Wake Error (SWE) timer enables a safe transition to Sleep mode after 4 minutes of inactivity in Standby mode, ensuring the device transitions to low-power Sleep mode if the MCU fails to transition it to Normal mode.
- How does the TCAN1043A-Q1 support wake-up events?
The device supports local wake-up via the WAKE pin and initiates system start-up by driving INH high when a wake-up event is detected.
- What are the available package options for the TCAN1043A-Q1?
The device is available in 14-pin leaded (SOT and SOIC) and leadless (VSON) packages with wettable flanks for improved automated optical inspection (AOI) capability.
- Is the TCAN1043A-Q1 qualified for automotive applications?
Yes, the TCAN1043A-Q1 is AEC Q100 (Grade 1) Qualified for automotive applications.
- Does the TCAN1043A-Q1 support functional safety?
Yes, the device is Functional Safety-Capable with documentation available to aid in functional safety system design.
