Part Number: TIDA-010065
I am wondering if you could help explanate the function of the components connected to the SHTDN pin of AMC1311.
For different versions of schematics, the external components are different.
Hello Stone Wang
Thank you for looking at TIDA-010065. and also thank you for bringing this question up. For assembly and testing please use the version with the DNP enabled.
R26 R27 + internal 100K pull up disables the SHTDN. Please look into the data sheer for the logic input level thresholds.
The current configuration works but populating R26 with OR could also be considered.
We will look into making these updates during the next opportunity for the design update.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Kallikuppa Sreenivasa:
Thanks for your prompt reply.
Could the customer directly connect the SHTDN pin to the Ground?
Compared to the circuit with R26 and R27, what are the disadvantages for the circuit directly connected SHTDN pin to GND?
In reply to Stone Wang:
Thank you for the reply and query.
The way we do the reference designs , we provide provisions in the circuit such that when possible another device can be mounted for some quick testing.
Since this is a digital input, i do not see any disadvantage connecting SHTDN to Gnd directly as you have suggested.
Thanks for your confirmation.
The customer wants to evaluate the performance of TIDA-010065, I am wondering if you could tell me how to apply for this reference design?
