DRV8814: Maximum rating of A/B-OUT1/2

Part Number: DRV8814

Hi all

Would you mind if we ask DRV8814?
How much is Maximum rating of A/B-OUT1/2?
Is the value is Minmum –0.7 to MAX VM + 0.7?

As the background of this question, Bout1 might be more than ABS condition.(Please refer to the wave form.)
However, if the minmum value of absolute maximum rating is -0.7V, we assume that it means VF=0.7V at body diode at FET.
Therefore, if it is very short term, there will be not problem.(The device is not damaged.)


CH1:VM(10V range)
CH2:DECAY(5V range)
CH3:BOUT1(20V range)
CH4:AOUT1(20V range)

Kind regards,

Hirotaka Matsumoto

  • Hi Matsumoto-san,

    -0.7V to VM+0.7V is ok. You are correct that this is the body diode conducting the current during dead times.

    It is difficult to determine the exact voltage on the scope with a differential probe from the pin to the device ground.
