Hi,

Could you tell me the pull-down resistor and ON resistance of fault pin?
Is VOL=180 mV based on ON resistance?
Customer wants to know the resistance value inside the TPS2557.

Hi Tsukui-san,
Currently we don't have that data avalible, and it's not one of our EC data. Do we know why customer need that?

Best regards,
Feifei

Feifei-san,

Thank you for your response.
When calculated in light of the data sheet the following descriptions, Rds(on) becomes 180Ω.
Customer thought to be too large as the Rds(on).
Therefore, I got a question about pull down resistance.

Best Regards,
