Part Number: DRV8303 Hello,
I would like to ask about start-up of DRV8303.
On the document , DRV8303 datasheet,8.8.1, would you please tell me, why the SH_x pin voltage at start-up should be less than 8.5V, the reason is to prevent any malfunction anywhere…
Part Number: DRV8303 I've used the DRV8303 several times in different boards. One layout is not working. It was mostly copied over from a different design.
The layout changes had little to do with the DRV8303's layout and nothing to do with its schematic…
Part Number: DRV8303 Other Parts Discussed in Thread: MOTORWARE Hello,
I would like to ask a question about InstaSpin Lab 10a,Overmodulation.
If we would like to maximize the output duty, changes the constant value "USER_MAX_VS_MAG_PU" to 2/3(=0.667) on…
Part Number: DRV8303 We use a DRV8303 in one of our products. Sometimes there is an issue with current sensing.
Without any motor attached to our board an no motor voltage (PVDD) connected, the current sense output (SO1 and SO2) is not correct.
I have…
