Hi Team,

We understand that if we don’t use /ERR(9pin) and /SENSE_EN(8pin), those pins are Open (no connected).

Is my understanding correct?

Hi Kanemaru,

/ERR is an output pin and it can be OPEN. For /Sense_EN, this is an input pin which is used to control the status of SENSE1 and SENSE2, floating an input pin is not recommended, I would suggest you either connect this pin to a digital low or high.

Hi Jason-san,

We have additional question.

We don’t use current sense function so we have to set “/SENSE_EN=High”.

Therefore, we start up " /SENSE_EN " and "EN" at same time.

Could you please let us know if you have any concern?

Regards,

Kanemaru

Hi Kanemaru-san,

There are no sequencing requirement on EN and SENSE_EN. Just be careful to share the same power rail between EN and SENSE_EN as their absolute maximum voltage ratings are different.
