Hi support team.
Is my understanding correct as following Figure?
If yes, the measured body diode VF value during the dead time period is 1.06V, and it is incomprehensible why it exceeds 1V.
Also, since this exceeds the absolute…
Part Number: DRV8426 Hi support team.
My customer has a critical issue.
-1.75V (186ns) undershoot is occurring at AOUT output. The waveform is below.
The absolute maximum rating is -3V for 100ns, is this acceptable? If NO, could you please give me some…
