LM3880: about EN

Part Number: LM3880

Tool/software:

I have a question regarding the operation of the EN pin of the LM3880. The datasheet mentions glitches during the assertion of EN. Can the same concept be applied to when EN is de-asserted? If the above is possible, up to how many milliseconds of noise can be masked on the EN pin? Would it be 400 μsec?

Best regard.

Hi

The glitch free applies on both on and off case.

It is the same as explained in the data sheet. that the delay restarts when the EN is toggled.

Dear Yehe

Thank you for your quick response.

I understand it.

Just to confirm, is it correct to understand that the LM3880 does not react to noise below td1?

Best regard.
