Part Number: DRV8426 Tool/software: Hi,
Please find the below schematic for DRV8426
sometimes, during power recycle it gets trapped in improper condition,
where we can observe toggling in "fault" pin & similar activity can be observed on winding output…
Part Number: DRV8426 Hello team
I have a question.
Is there a risk of nFault output due to the thermal pad not being connected to ground? My customer made a mistake in pattern design and tested with the thermal pad not connected to GND, and nFault was…

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…

Part Number: DRV8426 Hi Team,
Can you please check and advise following request?
"
In our circuit, voltage values on all pins seem normal. But when I give 1 (logic high) to the nsleep pin, the nfault pin drops to 2.2V. (Logic 1=5v) When I give 0…
