Part Number: TMS320F28027F Other Parts Discussed in Thread: DRV8305 Hello
Greetings of the day!!!
I am using F28027F + DRV8305 for driving BLDC motor. I am using projlab05b.c. In projlab05b.c i have written follwing code
float A_RPM=5.0;count++; if(count…
Part Number: DRV8305-Q1 hi expert
For ULVO function in datasheet, i have two questions
Q1: How can i understand the parameter of PVDD falling and PVDD rising?
Let us assume PVDD is 10V now, when PVDD is rising to 42.5V(10V+32.5V( shown in datasheet )) because…
Part Number: DRV8305-Q1 Other Parts Discussed in Thread: DRV8305 Hello,
we are using the DRV8305NQPHPQ1 as the gate driver for our BLDC motor control board and are experiencing a jump in the the total current to the board from 70 mA to 390 mA when the…

Part Number: DRV8305 I have a 3phase BLDC motor driver using DRV8305. During deceleration, I'm considering closing only the low side switches (all 3 simultaneously) to perform eddy current braking while using low side shunts to monitor the current so…
thanks for your input,
I started several trials to optimize the signal quality, but in the end I couldn't achieve a big improvement in scope of the existing pcb design.
At first to your questions:
If analyzing the signal quality by monitoring…
kura said: Is it okay to assume that the charge pump normally does not drop to 5.3 V (= the charge pump's low voltage protection does not work) within the range of PVDD = 4.4 to 45 V?
The specification in the register setting is 4.9V typical…
