Part Number: DRV8305 Hi,
I am working on a battery powered application (3S,LiPo) with DRV8305. I am wondering about the power sequencing with hardware design prospective. Since, DRV8305N requires a 3.3V supply for on VREF pin for internal current sense…
Hi Cherry,
Thank you for waiting. What is the current limit set on their supply? When a load is connected to the supply (i.e. the motor) and there is a current limit set on the output, the voltage will change accordingly. This is likely the issue the…
Part Number: TMS320F28027F Other Parts Discussed in Thread: DRV8305 , , MOTORWARE , TMDSEMU200-U My application is to rotate BLDC motor from RPM 5000 to 10000. When I am using TI's Launchpad XL Tms320f28027f with DRV8305 motor is rotating as per my requirement…
Hi Kura,
kura said: they just wanted to know that there was no problem with their usage and that it was operating within specification.
The spiking on PVDD that they are seeing should not cause any problem to the device or its operation. Also, even with…
