LIN Protection
Highlights:
- LIN: Single ended data transfer interface
- LIN clusters consist of 1 master and up to 16 slave nodes
- Construction: One wire for data transfer + ground
- Bidirectional configuration is needed to protect from line faults and miswiring
- Working Voltage range of 12V
- For a 12V battery system, in order to protect from miswiring, a 24V Protection diode is recommended
- Though a low data rate of up to 20kbps does not have a constraint on the capacitance, it is advised to have lower capacitance to ensure signal integrity
