Introduction

SIT1043Q is an interface IC designed for use between a CAN protocol controller and the physical bus, supporting flexible data rates up to 5Mbps with differential signal transmission capability between the bus and the CAN protocol controller. The SIT1043Q bus port withstand voltage reaches -58V to +58V, and the receiver common-mode input voltage ranges from -30V to +30V, making it suitable for 12V or 24V application systems. The SIT1043Q operates with multiple power supplies and features various system protection and diagnostic functions to enhance device and CAN bus stability. In addition, the SIT1043Q offers five operating modes: Normal mode, Silent mode, Standby mode, Sleep-wait mode, and Sleep mode. In low-power modes, both local wake-up and remote wake-up are supported, and the provided low-power mode management can significantly reduce power consumption in CAN bus application systems.
