Part Number: TLV3501
Hi , I am using this IC for comparaing two voltages but I am little bit confused for using SHDN/EN pin. Can yoy please tell me what should be the voltage at EN pin and how it affects the circuit? I read the data sheet but it is quite confusing.
Sorry for the confusion. If you apply a logic high level to the shutdown pin, the output no longer tracks the condition on the input pins and the quiescent current reduces. a logic low signal is required for the comparator to operate.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Chuck Sins:
So, I want my comparator to generate an ON-OFF signal for the gate driver than tell me the shutdown pin should range from (V+-1.7) to (V+-0.9) as given in the data sheet or I should ground it ?
In reply to Monika Dabkara:
To better explain, I created an example where I assume that (V+) = 5V.
Disable shutdown feature => SHDN < 3.3V = ((V+) - 1.7V)
Enable shutdown feature => SHDN > 4.1V = ((V+) - 0.9V)
The key is to notice that VL has a max allowable value to disable shutdown, while VH has a min allowable value to enable shutdown.
Hope this is more clear.
There has been no further questions, so I will close this thread. If additional support is required, feel free to reply or open a new thread.
