RE: DRV8711: DRV8711 ISGAIN Tolerance
Hi Sheldon, I have found some data to provide approximate die to die variations. Gain Variation (%) 5 +/-5 10 +/-5 20 +/-10 40 +/-10 The gain varies approximately .008% per degree C. Sorry this took so...

Part Number: DRV8711Hi All,There's no tolerance given on the DRV8711 datasheet for ISGAIN. Can anyone comment on what min/max values and tempco might be expected.

Found the problem...It turned out to be a bad USB2ANY module. These modules seem to kind of flaky.

Hi Mathew, Your assumption is correct, aside from the rsense, you would have to be able to provide 70V-73.3V for the logic input, have FETs able to handle the 70V as the low side gate could see this...

Hi Luis, I wanted to try to apply this to a 90V DC motor as they are the most readily available 1/2 to 1 HP motor. As a side note I have a DRV8701 w/ a 24V motor running but I have a few questions if...

Hi Anders, As I described above, two transistors are seried in the output circuit, and your need to use 2*Rdson in the total power dissapation calculation because of the H-bridge structure. Best...

Hi Kawai-san, - High input : Must be higher than 0.5 x VCC. (i.e. when VCC=6V, input must be higher than 3.0V to guarantee operation.) - Low input : Must be lower than 0.25 x VCC. (i.e. when VCC=6V,...

RE: DRV8701: Vref Adjustment based on motor size
Hi Rick,This does appear to be the case for the output voltage as expected. So I get that the Vref is cutting it off, but why would the instantaneous current be so high? I understand that if you look...
