Other Parts Discussed in Thread: TCAN1043
When I test RS485 communication by using THVD1451,THVD1451 can not detect A short to GND、B short to GND、A short to 3.3V、B short to 3.3V.
1.A short to GND :there is no signal on line A,but differential is normal
2.B short to GND: there is no signal on line B,and differential have some error data
3.A short to 3.3V: line A is high 3.3V,and differential have some error data
4.B short to 3.3V:line B is high 3.3V,idle bus is low,differential have no start signal.
If I want to detect these short condition,can be realized by using THVD1451.
Or I have to change to another transceiver?
If I have to change to another transceiver,which model you recommend?
Thanks.
