Part Number: DRV10987 Hi all,
We designed our custom DRV10987 board and we tryna start the motor but motor is dont working cause of given overcurrent issue, no short circuit between phases.. What is the primary problem?
Michaela,
DRV10987 uses 180 degree sinusoidal commutation technique to switch the FETs. I'm assuming you are referring to DC bus current as the "maximum value". Please note that the value read back from the current register is not maximum current or DC…
Cherry,
0x01 register reads back speed. 0x00 register reads back the fault. I believe you do a mass EEPROM write. In this case, values that you programmed to all the user-configurable registers (0x90 to 0x96) should be saved to EEPROM. Please make sure…
Device can trigger open loop fault when the initial position is inaccurate. I have disabled IPD and enabled "Align" as the startup method. Also, I changed R to 1.5 ohms and Ke to 190 mV/Hz and disabled ISD. Can you try these config values as shown in…
Ok so it looks like the open loop current is higher for your application. Can you replace C71 with a higher cap (20 uF) and try again? This can minimize the overshoot on VCC.
Part Number: DRV10987 Hi.
We want to run 2 phase brushless DC motor with DRV10987.
Is it able with DRV10987? can we disable one of phase?
and do you prefer any IC for run Brushless DC Motor at 24VDC,2A?
Hi Sohan,
Closing thread for now due to inactivity - can you let us know if the problem has been resolved?
Please let us know if further support is needed on this question. Thanks
Best Regards, Andrew

Part Number: DRV10987 Hi Vishnu,
After some days of running and kept in shelf, we are getting the same issue like it is not working (I2C communication itself failed), but while touching multimeter pin at the speed pin the motor driver starts spinning…
