SIT1043Q is an interface chip applied between CAN protocol controller and physical bus, supports 5Mbps Flexible Data-Rate, and has the capability of differential signal transmission between bus and CAN protocol controller. The SIT1043Q features a CAN bus fault protection from -58V to +58V, and the receiver common mode input voltage can reach -30V to +30V, which is suitable for 12V or 24V application systems. The SIT1043Q is powered by multiple power supplies and has multiple system protection and diagnostic functions to improve the stability of the device and CAN. In addition, SIT1043 has five working modes: normal mode, silent mode, standby mode, go-to-sleep mode and sleep mode. It supports local wake-up and remote wake-up in low power mode. The provided low power mode management can greatly save the power of CAN bus application system. SIT1043Q with INH pin function can control the LDO that supplies power to the system, so that the system can shut down LDO output in sleep mode to achieve the lowest power consumption, so as to meet the customers’ low power requirement.

Main applications is automotive and transport, such as body control, automotive gateway, ADAS, information, entertainment, BMS.
