Part Number: LM3880-Q1 Hi
I have a question about the pull-up voltage of FLAGx pin.
At the datasheet, the recommend voltage of FLAGx pin is -0.3V~VCC+0.3V. However the abs max is -0.3V~6.0V.
Is it possible the FLAGx pin is pulled up to 5V when the…
Other Parts Discussed in Thread: LM3880 Hi Sir,.
we ran a simulation with TI WEBENCH LM3880 in XC7K420T Flags: F1- F3,
What`s the Flags: F1- F3 of LM3880 details ? share us please , thank
Other Parts Discussed in Thread: LM3880 Hi all,
I've looked into datasheet of LM3880 and found that in a typical application there is pull up resistors in use on output flags. Since I'm using this device with Load Switches, I've two questions:
- When…
Other Parts Discussed in Thread: LM3880 Hello, I had ordered LM3880 for power sequencing purpose. I had connected 22uF capacitor to Enable pin. Circuit Works well, when i powered On VCC supply its gives desired delay (near by 3 seconds), but when i turned…
Hi Everyone,
The typical application in datasheet uses 100kohm pull up resistor on FLAGx pin. But typically 10kohm pull up is used at typical application so I think 100kohm is slightly large for pull up resistor. So can you explain the reason you use…

Hello,
I am doing some research & development on Power ON sequence circuit . I searched out online for same and got reference of LM3880 .
I referred datasheet and try to implement for my demo project.…
Hi All,
Has anyone tried to download the xbl file for this part ? When I click on the download link I get a cryptic display of the actual file instead of the download ?
I would like to have this file if anyone has it.
here is the url...the CAD…
Other Parts Discussed in Thread: LM3880 Hi!
I have a question regarding the LM3880 power down sequence.
We plan on connecting an open-drain output to the LM3880 enable pin.
I cannot find any information in the datasheet about how long the enable…
Hi All,
Please let me ask about absolute maximum rating of EN pin. I understand that the recommended maximum voltage is Vcc+0.3V however it will not be damaged to +6.0V because the its absolute maximum rating is +6.0V. Is my understanding correct? …
