Hi Pablo, besides RCA and RCB we also tuned the current holding current to get rid of the noise. Jan already explained this action. We did not succeed to take it away completely. We still have 10 to 15% that produce noise and therefor do not pass the test…
Part Number: DRV8818EVM Other Parts Discussed in Thread: DRV8811EVM , DRV8811 , , DRV8818 Hi team,
My customer needs DRV8811EVM for evaluation, but cannot find any stock from TI or disty.
Can we use DRV8818EVM? It seems possible if we replace DRV8818 chip…
Part Number: DRV8818 Hi,
In the datasheet, on page17, 8.2.2.2, IFS = VREF/(A*Risense) and in example, To achieve IFS = 1.25 A with RSENSE of 0.1 Ω, VREF should be 1.56 V.
Is this equation correct?
With 1.5V Vref, 0.2Ohm Risense, circuit is limited by…
Part Number: DRV8818 Hi team,
How do I set the pin to keep the motor functional? i.e. when moving to a specified position, the motor does not move and is applied torque.
Could you help resolve this case? Thanks.
