Hello,

What is maximum ENABLE Pin current (when VEnable=5V for example).or ENABLE pin resistance to GND.

I don't find any information about these in datasheet

Best Regards.

HI Sylvain,

I need to check out if this information is available. Could you explain why this information is important for designing your application?

Regards,
Sabrina

I use a open collector with pullup resistor to +5V to drive ENABLE pin of 3 TLV62568P ICs.
So, I need to calculate maximal resistor value of this pullup.

Sylvain,

You could use the input leakage into PG pin spec for EN pin too, typically 10nA. Depending on the current flowing into the open collector pin this could be eventually neglected
To be on the safer side for your design, I would recommend to take factor 10 of the typical value (10x10nA=100nA) while calculating the maximal resistor value.
