Original question:
Dear all,
I would like to know about ACOVP in BQ24773.
Our customer try to use BQ24773.
They are considering using an input voltage of 24V from the following data sheet.
At that time, the variation of Vin is assumed to be ± 10%.
From the following data sheet notation, our customers think that this variation is likely to get caught up in OVP.
Is there any way to avoid OVP?
I would appreciate it very much if you could reply as soon as you can.
Best Regards,
Y.Ottey
Hi,
Factoring in your +/- 10% variation, the input voltage could range from 21.6-26.4 V. I agree that this could trigger ACOVP, which has a typical rising threshold of 26 V.
Since 26 V is a fixed threshold, as shown in the block diagram below, the only way to avoid triggering ACOVP would be to use a lower input voltage. You can either step down your adapter voltage such that Vin does not exceed 26 V or you can use a different adapter that has a lower voltage.
Best regards,
Angelo
