Part Number: LM3880-Q1 What is the minimum EN low time needed to ensure that the power up sequence is done with the proper timing? In other words, if I have a 10 ms sequence 1 device (timing designator AA) and EN is low for 30 ms to ensure a normal power…
Part Number: LM3880-Q1 Other Parts Discussed in Thread: LM3880 Hello team,
My customer wants to decrease quiescent current at standby situation for LM3880-Q1.
LM3880-Q1 output should be 'L' at standby.
So, The current is needed not only LM3880…
Part Number: LM3880-Q1 Team,
Is the LM3880QMF-1AE/NOPB logic bearing?
I believe the reason for this question is because if it is programmable then there is a supply chain risk that my customer needs to manage/mitigate.
I am not sure I understand "you have to sink current from the EN pin to ground to stop it from turning itself on." 1) could you tell me the way I could do it ? 2) actually, R166 ties low EN pin when Q1 does not conduct. 3) I have physically…
Part Number: LM3880-Q1 Other Parts Discussed in Thread: LM3880 Q1. Customers use the LM3880-Q1 in cascade. *For the circuit configuration, refer to the attached file "circuit diagram".
