Part Number: DRV8704DRV8704
Dear Sir/Madam,
We use the DRV8704 in multiple products. The DRV8704 controls MOSFETS in an H-bridge configuration for brushed DC motor control purposes (PWM 18kHz). Sometimes the DRV8704 produces a gate driver fault…
Part Number: DRV8704 Hi,
Thermal pad solder issue. When the steel plate thickness is 0.12mm, the opening size is 2.9*4.7mm.
The height will be due to the large opening area, and the solder paste in the middle will be about 107um lower than the thickness…

Hi,
We are using DRV8704 driver ic for DC actuator control
Actuator specification- 32V,3A with load condition,1A no load condition
Mosfet -SQJB00EP-T1_GE3
2-channel,60V,30A,Rdson- 10.5 mOhms, Gate charge Qg-35nc,Vgsth-2…
Part Number: DRV8704 What is our approach for simulating a full system, motor driver AND motor? What are the tools and software recommended?
Thank you!
Part Number: DRV8704 Hi
I'm currently using an DRV8704 to drive a linear motor actuator, When I'm measuring MOT0A vs GND, I can see a negative voltage of -8.7V, it’s quick, around 10ns.
I’ve tried to remove it by adding 2 Schottky diode, one between…
Part Number: DRV8704 Hi all.
Cant get DRV8704 work. Immediately after I turn anu motor on Im getting a predriver fault error
Configuration:
ConfigRegisters.CTRL.bits.ENBL = 1;
ConfigRegisters.CTRL.bits.ISGAIN = drv8704_isgain_5;
ConfigRegisters…
Part Number: DRV8704 While the 8704 is capable of driving two motors it seems to feature a single SPI register for TORQUE, ENBL, OCPTH, and others. Is there a way to circumvent the limitation of having a single parameter for both motors, for instance…
Part Number: DRV8704 After resolving my Predriver fault I faced another issue. Contstanly getting xOCP overcurrent protection flag. Started to dig a bit and here is what I found:
These are waveforms from each gate of one bridge, after xIN1 set high…
Part Number: DRV8704 Hello, We designed a custom board using the DRV8704. The system drives a platform inside a water tank. The platform goes down by activating the motors and goes up with Archimedes' buoyancy. When the platform goes up the Archimedes…
Part Number: DRV8704 Other Parts Discussed in Thread: DRV8711 , , CSD18540Q5B Hi All,
Recently, i have a new designed dual channel dc controller board from a engineer.
It's been tested ok from the engineer using smaller motor. However, when we test…
