Part Number: TIDA-01090 Other Parts Discussed in Thread: NA555 , SN65HVD3082E Dear team,
Customer are looking for full duplex mode solution and find TIDA-01090 from TI website.
But this app note is half duplex mode. Could we design with two set of TIDA…
Hello Mounish,
One possible solution is this reference design that can be used with any RS-485 driver: ti.com/tool/TIDA-01090
If you can adjust parts, THVD1406 and THVD1426 also have auto-direction control built in.
Best,
Ethan
Part Number: TIDA-01090 Other Parts Discussed in Thread: BQ76940 , BQ76930 Dear all，
The available versions of the various acquisition chips can be compared. Different versions of the chips may have different IIC addresses or the same IIC address.
Now…
Hi Franz,
For the THVD14x6 family of devices they need to be used at the specified data rate for them to work properly.
That being said - auto-direction can be achieved with any part with enables through the addition of a timer circuit - as shown in…
Hi Lauren,
So RS-485 transceivers only implements the Physical layer (as RS-485 is a PHY only standard - data-link/network level control is not defined so it is up to system designer to determine what protocol is needed) - so communication is controlled…
Hi Charles:
Thanks for posting on E2E. This is a very interesting way to achieve auto-direction control in RS-485 communication.
Theoretically, this circuit works.
In transmit mode, logic zero is achieved by driving the RS-485 bus low while logic one…
Part Number: SN65HVD72 Other Parts Discussed in Thread: TIDA-01090 Hello TI Team
Currently we are using SN65HVD72D chipset, and controlling its DE and RE pin through single GPIO. Have a look at the attachment.
By making GPIO either high/low we are enabling…
Other Parts Discussed in Thread: TIDA-01090 Some my customers (2 in last week) see that TI updates their interfaces product lines and ask me about RS-485 with automatic direction control like MAX13488/MAX13487. We know that TI have reference design HOWTO…
That will work. If you did want to use THVD1450 for some reason, you could tie DE to VCC and /RE to GND and it would be equivalent.
Will this node ever need to receive data from other nodes, though? If so, then you might want to revise your approach so…
