This document describes the NCV7420EVB board for the ON Semiconductor NCV7420 LIN Transceiver with Voltage Regulator. The functionality and major parameters can be evaluated with the NCV7420EVB board. The NCV7420 is a fully featured local interconnect network (LIN) transceiver designed to interface between a LIN protocol controller and the physical bus. It integrates a LIN v2.1 physical transceiver and a low-drop voltage regulator, designed to work in harsh automotive environments and submitted to the TS16949 qualification flow.
The manual provides details on the evaluation board features, including oscilloscope test points, reverse protection, and filtering circuits. It covers the master/slave configuration options, functional description of the device's operating states (normal, low slope, stand-by, and sleep), and includes a schematic diagram and a bill of materials for the board.
| LIN Specification | LIN Compliant to Specification Revision 2.1 |
|---|---|
| Bus Voltage | ±45 V |
| Transmission Rate | up to 20 kBaud |
| Voltage Regulator Output | 3.3 V or 5 V |
| Load Current | up to 50 mA |
| ESD Protection Level | up to ±12 kV |
The NCV7420 provides four operating states: normal mode, low slope mode, stand-by mode, and sleep mode.
Yes, the NCV7420 evaluation board can be configured as either a Master or Slave node.
The maximum transmission rate is up to 20 kBaud.
