2.1.2
An MCP2021-500 LIN bus transceiver connects to a LIN or J2602 compatible network.
The MCP2021 also contains a voltage regulator that outputs 5.0 V
protects the LIN bus pin from transient voltages. The capacitor between the LIN bus pin
and ground should have its value adjusted to the particular network topology.
For more information on the LIN transceiver, refer to the “MCP202X LIN Transceiver
with Voltage Regulator” (DS22018).
2.1.3
The board gets the power supply and the bus connection through three through-hole
pads. The voltage should be in the range of 8-18 V
integrated, automotive grade voltage regulator is reverse battery, transient and load
dump protected.
2.1.4
Figure 2-1 illustrates the system connector and Figure 2-2 illustrates the programming
connector.
