Dear,

In the UCC21750 the EN pin is disabled by default, can we use RDY output to pull up the EN pin ??

Thanks and regards

Hi Anoop,

Thanks for reaching out. To enable the gate driver, the EN pin should be High and is hence it is recommended to use a pull up and tie to VCC. RDY is also pulled up to VCC hence they can be paralleled.

Hope this helps!

Best,

Pratik
