Part Number: DRV8251A Hi team,
I’m configuring the DRV8251A peripheral circuit to get correct current regulation after paralleling with my customer, e.g., setting each Itrip=1.5A, and need the total current regulated @ 3A. However, they have get the result…
Part Number: DRV8251A Hi support team.
My customer has asked us regarding settings when current regulation is not used.
Please provide recommendations for VREF and IPROPI settings when not using current regulation.
Best regards,

Part Number: DRV8251A Hi team,
My customer wants to have a test on OCP performance and they add a sliding resistor to change the load to enter OCP status,
But actually they are not sure the protection they catched is OCP or OTP. Do u have any advice on…
Part Number: DRV8251A Hi team,
My customer find that they tested the tpd of out and in is 41us which is far beyond the tpd of 1us in the datasheet .Could u kindly help to explain what is the possible reason? And will the tpd affect the normal work of…
Part Number: DRV8251A Other Parts Discussed in Thread: DRV8251 Hi Team,
My customer is testing the DRV8251A and we have some question below,
1.Customers are conducting reliability tests on DRV8251. They increase the VM to about 52V and find that the chip…
Part Number: DRV8251A Hi,
I try to find a application note to create a sensorless speed regulation for a BDC motor in H bridge configuration.
I thought I could detect the speed of the motor with a measurement of BEMF and regulate it with a uC.
But…
Part Number: DRV8251A Hey team,
Quick question - when the device is in UVLO, what does it look like to outside components? Does it appear in Hi-Z Mode or Ground on the outputs?
Thanks,

Part Number: DRV8251A Hey team,
Got a few more questions regarding the DRV8251a. Within the datasheet the Abs. Max for current is stated as 'Internally Limited.' I was curious how this was set? It is through the current mirror that monitors IPROPI?…
