NCV7428 http://onsemi.com 8 functional description vs supply input v s pin of NCV7428 is typically connected to the car battery through a reverse?protection diode and can be exposed to all relevant automotive disturbances (iso7637 pulses, system esd ...). v s supplies mainly the integrated lin transceiver. filtering capacitors should be connected between v s and gnd. during power?up of the battery supply, v s pin must reach v s_porh level in order for the circuit to become functional ? the internal state machine is initiated and the v out regulator is activated. the circuit remains functional until v s falls back below v s_porl level, when the device enters the shutdown mode. vout low?drop voltage regulator the application low?voltage supply is provided by an integrated low?drop voltage regulator delivering a 5 v or 3.3 v output v out . it is able to deliver up to 70 ma with given precision and is primarily intended to supply the application microcontroller unit (mcu) and related 5 v or 3.3 v loads (e.g. its own mcu?related digital inputs/ outputs). an external capacitor needs to be connected on v out pin in order to ensure the regulator?s stability and to filter the disturbances caused by the connected loads. all low?voltage digital pins are related to v out . lin transceiver NCV7428 integrates on?chip lin transceiver interface between physical lin bus and the lin protocol controller. this lin physical layer is compatible to lin2.x and j2602 specifications. NCV7428 lin2.2 compliant physical layer can be combined on the network with all previous lin physical layers. NCV7428 lin transceiver consists of a transmitter, receiver and wakeup detector. the lin transceiver can be connected to the bus line via lin pin, and to the digital control through pins txd and rxd. the functional mode of the lin transceiver depends on the operating mode and on en pin state ? see figure 3. the lin transceiver is supplied directly from the v s pin. lin operating modes in lin active mode the transceiver can transmit and receive data via lin bus with speed up to 20 kbaud for normal slope mode and 10 kbaud/s for low slope version. the transmit data stream of the lin protocol is present on the txd pin and converted by the transmitter into a lin bus signal with controlled slew rate to minimize emc emission. the receiver consists of the comparator that has a threshold with hysteresis in respect to the supply voltage and an input filter to remove bus noise. the lin output is pulled high via an internal pull?up resistor (typ. 30 k ). for master applications, it is needed to put an external resistor (typ. 1k ) with a serial diode between lin and v s . the mode selection is done by en = high. the transmission is only initiated with the txd falling edge in lin active mode. entering this mode with txd already low will not lead to transmitting bus dominant signal. when leaving normal mode (en pin falling edge), the transmitter is deactivated immediately. the lin wakeup mode can be entered if the en pin is low. the lin receiver stays active to be able to detect a remote wake?up via bus. the lin transmitter is disabled and the slave internal termination resistor of 30 k between lin and v s is disconnected in order to minimize current consumption. only a pull?up current source between vs and lin is active. the valid lin wakeup event causes driving rxd low until en pin is pulled high. a wakeup pattern that is initiated in lin active mode and ends in lin w akeup mode is also considered a valid w akeup event. the lin wakeup mode is also forced if the device enters to the sleep operating mode. the lin off mode provides extreme low current consumption, lin transceiver is fully deactivated. pin rxd stays high (as long as v out is provided) and logical level on txd is ignored. the bus pin is internally pulled to v s with a current source (thus limiting v s consumption in case of a permanent lin short to gnd). this mode is entered when NCV7428 is in shutdown mode (v s < v s_porl ) or in thermal shutdown mode (t j > t j_sd ).
