Part Number: DRV8426
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…

Hello, Fatih,
It needs some bulk capacitors on the VM to absorb the energy sending back from the motor winding. But, the bulk capacitor may not related to this issue.
DRV8426 provides the output current regulation. The output voltage is just a result…
Part Number: DRV8428 Other Parts Discussed in Thread: DRV8426 , DRV8424 Hi team,
Can I use DRV8428 and DRV8426 replace A4988 and A4985 ?
If any better suggestion pls let me know.
Part Number: DRV8426 İn my custom circuit , drv8426 VM pins voltage is 24V and VCP pins voltage 23.5 V . According to datasheet VCP voltage should higher than VM.(VCP = VM+2). And in my circuit fault pin voltage is 2.2V in this state.
İs VCP need to powered…
