Part Number: DRV8701 Hi Team,
The waveform collected by SO when the motor is short-circuited is as follows:
Examples of SO waveforms in the manual are as follows:
When a peak current occurs, it is observed in the manual that SO has a climbing process…
Part Number: DRV8701 Other Parts Discussed in Thread: DRV8714-Q1 , DRV8706-Q1 , DRV8718-Q1 Hello,
we are using the DRV8701 to drive an H-Bridge for an electric motor employed in an application where we are asked to have a certified current limit protection…
Hi Murugavel,
Customer wants to know how the SO pin of DRV8701 works?
It can be seen from the screenshot of the oscilloscope that when the current is chopped, the voltage collected by the voltage dividing sampling point of SO directly becomes 0. This causes…
Part Number: DRV8701 Other Parts Discussed in Thread: DRV8251A Hello,
We want to control a Linak LA14 motor using the DRV8701:
We want to control the motor in one direction: open or close. Could you comment on this if you see any challenges?
-This…
Hi Jason,
Happy to hear you were able to address the hardware changes without spinning the PCB by using a dual AND gate and using firmware to change the direction. I'm glad your application works very well at 15kHz with the DRV8701. Thank you for the…
Hello Iiya,

Part Number: DRV8701 Other Parts Discussed in Thread: TPS40070 I have searched ti.com but cannot find a published errata sheet for the DRV8701ERGER.
If one exists, could you provide it to me please?
many thanks

Hi Supriya,
Could you please provide the answers to the following questions so we are better able to understand this issue?
1) Are the FETs being configured for high-side or low-side?
2) Are you receiving any faults while operating?
3) After the CSD18542KCS…
Part Number: DRV8701 Dear teams,
Recently, one of our DRV8701 chips failed, and the four gate output control voltages were abnormal.
The phenomenon is that the output voltage without load is normal, and the load ON the chip will stop at once, reporting…
