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,…
Part Number: LM3880 Tool/software: Team,
When LM3880MF-1AANOPB is used in below circuit, there is something wrong and doesn't work normally.
Could you help to check the schematic! is there any missing?
Sequence Device: LM3880MF-1AANOPB

Part Number: LM3880 Tool/software: I have two circuits that are pretty much identical in pspice, and I'm getting very different results. For example, in the second circuit, Flag2 and Flag1 deassert nearly simultaneously. Here are the netlists: Circuit…
Part Number: LM3880 Tool/software: I’m working on a project that involves powering up 13 different LDOs in a specific sequence. I plan to use the LM3880 for power sequencing, but I have a few questions:
Output Flags : I understand the LM3880 has…
Part Number: LM3880-Q1 Tool/software: Hi,
On datasheet page of 10 there is a Equation 1 that is used for t_enable_delay.
What is the result of calculation - is it ns or ms?
Also can you give an example of calculation with "common" Cen calue. …
Part Number: LM3880 Tool/software: I am using the LM3880 to set up a startup sequence for my FPGA power supply. I have a question about the EN pin. Does the power sequence of the LM3880 work even if the EN pin = open (not connected)?
Thank you in advance…
Part Number: LM3880 Tool/software: Hello,
I place an RC circuit on the EN pin using a 51K ohm in series with a 4.7uF capacitor, could you please guide me on how to calculate the delay time of flags?
If you could share a calculate tool, that will be…
