Part Number: DRV8307 Hello
I am going to use drv8307 in my motor control design it has recommend frequency range from 16 to 50 kHz.Can this frequency varied between 16 to 50 kHz or it needed any constant frequency between 16 to 50 kHz
Hey Sharath,
If you reduce the value of the gate MOSFET gate resistors you have do these problems go away? Also, are you sure the header pins from the DRV8307 to the MOSFET PCB are strongly connected with each other?

I am using the CSD18540Q5BT MOSFETs in place of those suggested in the DRV8307 example schematics. I'm running into some issues debugging my custom board and was hoping someone could…
Hello,Rick & Prashant :
Thanks your suggestion, I fix the glitches on the phase of Hail Sensor.
I use the single ended mode on DRV8307, The HU- & HV- & HW- pin are connected to a resistance for 2V of VREG
I add a 4.7uF capacitance on the resistance…

Part Number: DRV8307 Hi Team,
The customer is using DRV8307. He has some qusestions as belows.
Q1: Locked Rotor question:
The customer refer to 7.3.11.6 Rotor Lockup (RLOCK) of the datasheet. If the motor is needed to stop operation normally, is…
Part Number: DRV8307 Other Parts Discussed in Thread: DRV8306 Hi.
I assembled a PCB including DRV8307 like the attached schematic.
However, when nENABLE is low active and PWM signal is supplied the gate drive signal HSG is output about 0.6V level…

Hi
1.
I believe we don't need to control dead time if TI's motor driver has "smart gate driver architecture".
Is my understanding correct?
2.
Does DRV8307 have smart gate driver architecture?
If yes, how we can recognize…
