TCAN1043ATDRQ1
Description
Technical Parameters
The TCAN1043ATDRQ1 is an AEC Q100 (Grade 1) qualified CAN transceiver designed for automotive applications, combining robust functional safety capabilities with compliance to ISO 11898-2:2016 standards. Its wide input voltage range of 1.7 V to 5.5 V and support for both classic CAN and CAN FD up to 8 Mbps (TCAN1043A-Q1) or 5 Mbps (TCAN1043AT-Q1) make it versatile for various automotive power supply scenarios. The transceiver offers adaptive power management through multiple operating modes, including Normal, Silent, Standby, and Low-power sleep modes, enhancing energy efficiency. Noteworthy features include a Sleep Wake Error (SWE) timer for safe transitions between modes, high-voltage INH output for efficient power control, and comprehensive protection mechanisms such as ±58-V CAN bus fault tolerance, load dump support, IEC ESD protection, under-voltage protection, thermal shutdown, and TXD dominant state timeout. With package options in 14-pin leaded (SOT and SOIC) and leadless (VSON) configurations, the TCAN1043ATDRQ1 provides engineers with a reliable and adaptable solution for building resilient automotive communication systems.

Description:
The TCAN1043A-Q1 is a high-speed Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2016 highspeed CAN specification. The device supports both classical CAN and CAN FD data rates up to 8 megabits per second (Mbps) (TCAN1043A-Q1) or 5 Mbps (TCAN1043AT-Q1). The TCAN1043A-Q1 allows for system-level reductions in battery current consumption by selectively enabling the various power supplies that may 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 TCAN1043A-Q1, while monitoring the CAN bus. When a wake-up event is detected, the TCAN1043AQ1 initiates system start-up by driving INH high. The TCAN1043A-Q1 features an SWE timer that enables a safe transition to Sleep mode after 4 minutes (tINACTIVE) of inactivity in Standby mode. This makes sure the device is transitioned to low-power Sleep mode if the MCU fails to transition the device to Normal mode.
