Features of SN65HVDA195-Q1 Conforms to Lin physical layer specification revision 2.0 and to Lin's SAEJ2602 recommendation Lin bus speed up to 20-kbps Lin specified maximum and MOST ECL speed down to 0 baud Support for ISO 9141(K line) Meet the requirements of automotive applications Sleep mode: ultra-low current consumption, allowing wake-up events from the LIN bus, wake-up input (external switch) , or host microcontroller High speed reception capability ESD protection on LIN pins reaches ± 12 kV (mannequin) Lin pins can handle voltages from -40 V to 40 V Can withstand transient damage in automotive environments (ISO 7637) Use 7V to 27v DC power (Lin specifications 7v to 18v) for expansion operations Interface to a microcontroller with 5V or 3.3 V I/O pins Wake-up request on the RXD pin External regulator control (INH pin) Integrated pull-up resistor and series diode for Lin Responder applications Low electromagnetic radiation (EME) , high electromagnetic immunity (EMI) The bus terminal short circuit protects the battery from short circuit or earthing short circuit Thermal protection System-level ground disconnection fault protection System level ground shift operation No power nodes do not disturb the network SN65HVDA195-Q1 description The SN65HVDA195 device is a local interconnect network (Lin) physical interface and MOST ECL interface, which integrates a serial transceiver with wake-up and protection functions. The bus is a single-wire two-way bus, usually used for data rate of 20kbps low-speed vehicle network. The device can transmit at an effective data rate of 0 kbps because it has no dominant state timeout. The protocol output data stream on TXD is converted from SN65HVDA195 to bus signals by a current-limiting waveform driver, as described in Lin physical layer specification revision 2.0. The receiver converts the data stream from the bus and outputs the data stream through RXD. The bus has two states: the dominant state (voltage close to ground) and the recessive state (voltage close to battery) . In the recessive state, the bus is raised by the SN65HVDA195 internal pull-up resistor and the series diode, so no external pull-up element is required for the responder application. According to the LIN specification, the Commander application requires an external pull-up resistor (1k ω) and a series diode.
