XINLUDA XL1050

The XL1050 is the interface between the Controller Area Network (CAN) protocol controller and the physical bus. It is primarily intended for high speed applications, up to 1 MBaud, in passenger cars. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller. The XL1050 is an interface chip between the CAN protocol controller and the physical bus, which can be used in trucks, buses, cars, industrial control, etc. It can reach a speed of 1Mbps, and has the ability to transmit differential signals between the bus and the CAN protocol controller, and is fully compliant with the "ISO 11898" standard. The driver stage of the XL1050 has current limiting protection to prevent the driver circuit from short-circuiting to positive and negative supply voltages. Power consumption increases when a short-circuit occurs, and the short-circuit protection feature protects the driver stage from damage. The XL1050 has an over-temperature protection function. When the over-temperature protection is triggered, the current of the driver stage will be reduced because the driver tube is the main energy-consuming part, and the current reduction can reduce the power consumption and thus reduce the temperature of the chip. At the same time, the rest of the chip still works normally. The built-in TXD dominant timeout timer circuit prevents the bus line from being driven to a permanently dominant state (blocking all network communications) if pin TXD is forced permanently low due to a hardware and/or software application failure. The timer is triggered by a negative edge on pin TXD. If the duration of a low level on pin TXD exceeds the internal timer value (tdom), the transmitter is disabled, driving the bus into a recessive state. The timer is reset by a positive edge on pin TXD. Control pin S allows selection of two operating modes: High Speed Mode or Silent Mode. High speed mode is the normal mode of operation and is selected by grounding pin S. If pin S is not connected, it is the default mode. However, it is recommended that pin S be grounded to ensure EMI performance in applications that use only High Speed mode. In silent mode, the transmitter is disabled. All other IC functions continue to operate. Silent mode is selected by connecting pin S to VCC and can be used to prevent network communication blocking due to a
