Hi team,
A customer of mine had the following question regarding LM3881.
We have a number of power supplies with VIN at 5V. Their active high enables are connected to the flag outputs of a LM3881. The flag outputs are open drain so they have a pull-up. So if the LM3881 does not drive the flag outputs, the enables are high.
In our situation, the LM3881 is supplied by the same 5V.
Questions:
What happens with the flag outputs during power-up? We see that the minimum supply voltage of the LM3881 is 2.7V.
Are the outputs guaranteed to be low before this is reached?
or will the output glitch?
Hoping you to get some assistance.
Thanks,
Obinna.
