SIT1022Q Dual channel Local Interconnect Network (LIN) transceiver
■SIT1022Q is a dual channel Local Interconnect Network (LIN) physical layer transceiver that compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12V) and SAE J2602 standards. It is mainly suitable for in-vehicle networks with a transmission rate of 1kbps to 20kbps. SIT1022Q controls the state of the LINx bus through the TXDx pin, and can convert the data stream sent by the protocol controller into a bus signal with the best slew rate and waveform shaping to minimize electromagnetic radiation emission (EME). The LIN bus output pin has an internal pull-up resistor. Only when used as a master node, the LIN bus port needs to be pulled up to VBAT through an external resistor in series with a diode. SIT1022Q receives the data stream on the bus through the LINx pin, and transmits the data to the external microcontroller through the receiver’s output pin RXDx.
■SIT1022Q can operate from 5.5V to 27V and supports 12V applications. SIT1022Q has an extremely low quiescent current consumption in sleep mode and standby mode. It can quickly minimize power consumption in the event of a failure. The device can be placed in normal mode via a signal on the pin SLPx_N.
