BQ40Z80: Short circuit discharge time over

micou ludovic

Part Number: BQ40Z80

Tool/software:

Hello,

I have configurate the ASCD to have 0µs to detect the short circuit discharge with a current of 33.3A. i have a shunt of 1mohm.1526.Gauge after temp.gg.csv

But the delay to detect the short circuit is 360µs.

Without the capacitor C1,C2 and C3, the time to detect the short circuit is 300µs.

How can i have a detection at 0µs.

Thanks,

Best Regard,

Ludovic Micou

Hell Ludovic,

We will continue to work on your question, today is a national holiday, Memorial Day.

Thank you,

Hello Ludovic,

We don't recommend removing capacitor C1,C2 and C3 but it is not possible to have a ASCD of 0µs. It seems that you are already hitting the limit in terms of detection times

Thank you,
Alan
