Hi
Customer is using SN65HVDA100-Q1 as LIN Transceiver for the Seat ECU project.
The customer is asking the question because there is a difference between the Datasheet specification when measuring the range of operating voltage with the sample.
* Test results (Voltage level is Pin 7 VSUP measurement)
- Normal operating interval : 7.9V or higher
- LIN Error: 6.9V ~ 7.9V
- LIN shut off : 6.9 volts or less
The data sheet specifications are as follows.
* Extended Operation With Supply From 5V to 27V DC (LIN Specification 7 V to 18 V)
Q : The Nominal supply voltage is a minimum of 7 volts or more. However, LIN errors are occurring up to 7.9V.
Is that normal?
