Hi Kura-san,
When PVDD < PVDD_UVLO1 for greater than 8-10us, all SPI registers will be reset as internal logic is disabled.
Before 8us, the registers should not lose any contents. I cannot comment on whether registers will be partially reset or fully…
Part Number: DRV8305-Q1 Other Parts Discussed in Thread: DRV8305 Hi team,
Customer cares about the power consumption in the system, therefore they would like to put DRV8305 in sleep mode after power on. I found in datasheet state machine that the IC is…
Part Number: DRV8305-Q1EVM Other Parts Discussed in Thread: MOTORWARE Hi,
use DRV8305-Q1EVM module Board and I use proj_Lab02b software. This software includes EST Module. When motor is started, this EST module estimates motor parameter. Then, control…
Other Parts Discussed in Thread: DRV8305-Q1 , MOTORWARE , INSTASPINUNIVERSALGUI , DRV8305-Q1EVM Hi, Team
My customer want to develop the custom motor.
Can you allow to access the MCU source code by signed the NDA?
I am promoting the NDA to disclose information…
Part Number: DRV8305-Q1 Other Parts Discussed in Thread: DRV8305 Hi all
My customer is using the DRV8305-Q1 and they are seeing potential issues due to soldering cracks.
They want to run a thermal simulation for this PCB and therefore ask for the CTE…
Part Number: DRV8305-Q1 Hello,
I have noticed 500mA or so current spikes on PVDD pin apart from normal 35mA power consumption. This has been measured while no PWM signal was applied to the driver and the gates were enabled. After disabling gates, no spikes…

We got additional question from customer. Please advise us.
Please let us know what is the maximum…
Part Number: DRV8305-Q1 Hi~ All.
In DRV8305-Q1, there is only typical PVDD current for operating(20mA) and standby(5mA), but what is max PVDD current consumption for both?
Thanks.
Part Number: DRV8305-Q1 Hi team,
There is a probability that the drive chip will shoot through approximately 1 per thousand after the bulk shipment, mainly show as the drive chips PIN27 and PIN41 have two holes on the surface of the chip and some of the…
Part Number: DRV8305-Q1 Hello
In my design, the DRV is powered after the MCU.
For proper power up all DRV IO pins should be set to 0. but at the same time, SPI_CS should be set to 1 to ensure that there is now communication to the DRV.
we have encountered…
