LM73605-Q1: What is EN status from internal design

Johnny Guo

Part Number: LM73605-Q1

Hi, team.

I see in LM73605-Q1 datasheet, EN is not allowed for left floating use. What is EN internal status? Is it pull-up, pull-low, or just high impedance?

Thanks.

Hi Johnny,

You can consider the EN circuit as voltage comparator with very high input impedance on EN pin, floating the EN pin will cause undetermined voltage level which leads to unexpected enable/disable behavior in noisy environment.
