    Hello Qiurui, Those pins are to be used with an FG trace. If you do not have an FG trace, please leave these pins unused. You can look at www.ti.com/.../TIDA-00197 to see how it is done in that design. See this image for an example of an FG trace on a…

    Hi Sadashiva, Thanks for posting to the MD forum! If not using the FG interface, you can leave the FGFB, FGINN_TACH, and FGINP as floating. I used the schematic from TIDA-00197 as a reference: https://www.ti.com/lit/df/tidr561/tidr561.pdf?ts=1594044032103&ref_url…

    1) I am not sure if DRV10987 can spin motor up to 2000 Hz. I would think it would be unlikely since it is 2x the max frequency we recommend. I mentioned in the previous posts what causes the limitations of the max speed motor can be driven. If you want…

    Hello Aman, This would ultimately come down to how fast the sensor's output would be changing. A latch sensor would be the easiest to implement where it's output would go high everytime the magnet pole would leave the area of the sensor and then come…

    Hi Aleksei, Our DRV8308 is designed to keep good speed control of BLDC. I think it will be just fit for your application. Also it has great ability to be optimized for the application needs. either open (PWM input mode) or close loop (CLK input mode…

    Mikael, that is strange. You can also look at the schematic of this TI Design as a reference: www.ti.com/.../tida-00197 I'm most suspicious about something being wrong with one of the power pins: CP1, CP2, VCP, VM, VINT, or VREG. Check for shorts with…

    Hi Dharmendra, 1) We will research this for confirmation. 2) Please look at the DRV5013, which is used in the TI reference design http://www.ti.com/tool/TIDA-00197. In this case, the three hall sensors are placed at 45 degree increments. A list of hall…

    I would like to be able to use Open loop functionality (I feed it a 5V or 12V pwm, or analog voltage and it goes - will the CLKIN pin work for that?). Is the DRV8308 the chip for the job? Yes. The VIH for CLKIN is 1.5-5.5V. Is the DRV8308 a better/newer…
