Ersan,
For R401 & R403 = 1kohm, you have a failsafe voltage of +30mV. Given V IT(+) of -10mV for the ISO1176T, this gives you 40mV peak-to-peak of noise margin. Whether this is acceptable will depend on the noise you expect to encounter in your operating…
Other Parts Discussed in Thread: SN6501 , ISO1176 , ISO1176T , PROFIBUS I compared the datasheets and application notes for both parts and wonder if the ISO1176T is basically a ISO1176 with integrated SN6501 or whether the transformer driver is different…
Hi Andreas,
Internal schematic ISO1176T and SN6501 is almost the same thus you could use them both without LDO if you have stable input voltage.
In other case be aware that bus side supply voltage for ISO1176T is in the range 4.75-5.25V (5V+-5%).…
Other Parts Discussed in Thread: PROFIBUS , ISO1176 , ISO1176T I use A 3 pin termianl for the profibus communciation as an alternative of the standard DB-9 connector, then contact 4kv ESD level test is necessary for the terminal of the A, B, and shield…
Other Parts Discussed in Thread: ISO1176T , PROFIBUS Hi,
The ISO1176T is dedicated Profibus transceiver ISO1176T,
Please check if itcan be used for standard Modbus?
BR,
Rotem.
The ADM2865E is an isolated RS-485 transceiver. What exactly do you mean with "UART"?
As far as I can see, TI does not have an isolated transceiver with integrated power supply; the nearest would be the ISO1176T with a transformer driver.
Part Number: ISO35T Other Parts Discussed in Thread: PROFIBUS , ISO1176T , ISO1450 , , ISO35 Hi sir,
Whether that ISO35TDW supports profibus or not. I am sure that supports rs485 but we need to make sure to know about the profibus support of that chip…
Hi, David,
I have found the problem, I got wrong about the DE signal of ISO1176T. However, I still have some questions:
1. Is ProfiBUS half duplex?
2. IDK5728 used GPIO4-6 to control the DE signal of ISO1176T. And I used GPIO3-25 to control the DE…
Hi Anand,
If a few of ISO1176Ts share a VCC2 power supply generated by a LDO and a transformer driven by D1 and D2 of one of ISO1176T, can D1 and D2 pins of the rest ISO1176Ts be left open?
Many thanks,
Bailin
Other Parts Discussed in Thread: ISO1176T I am looking for help in enabling a gpio based RTS in omap-serial for RS485 communication. I am not using the 8250 driver as it does not yet support RS485. I have a GPIO pin assigned as rts-gpio. I have verified…
