Part Number: DRV8308 Other Parts Discussed in Thread: DRV832X , DRV8306 , MCF8329A , MCT8329A Tool/software: Hi, TI expert
The customer used to use DRV8308(TI) part on the board applied to ATMs(Automated Teller Machines), but due to delivery issues at the…
Part Number: DRV8308 Tool/software: Hi Sir/Madam,
In the DRV8308 datasheet, 7.3.13.2 VMOV session,
"In some cases, if synchronous rectification is used, energy from the mechanical system can be forced back into the VM power supply.", "In the event of…
Hi Shin,
It is normal to have to write 0b to CPFAIL one time after ENABLE is changed low->high. Doing this should not cause a problem when using the DRV8308.

Part Number: DRV8308 Other Parts Discussed in Thread: MCF8329A Hi All,
Please find attached a mapping of all registers. My setup consists of the DRV8308 device driving a 450W motor at ~4000RPM on a battery driven system with nominal voltage of 25.6V in…
Part Number: DRV8308 Other Parts Discussed in Thread: MCT8329A Hi Team,
The DRV8308 controller implements closed-loop speed control, allowing the motor to run at a precise speed over a wide load torque range. It's required 100W of power to drive motors…
Part Number: DRV8308 Hi Team,
Use CLKIN signal frequency mode. When the speed is closed, the customer would like to control the speed of the motor by changing the size of the frequency, but the speed of the motor will become a jerkic change, which is…

Part Number: DRV8308 I am using the DRV8308 to drive a DC brushless motor in Clock Frequency Mode with speed closed-loop control enabled. I want to change the motor's speed, so I adjusted the frequency of CLK. However, instead of smoothly transitioning…
Hi Ahmed,
There are two adjustable gains in the DRV8308 are the LOOPGAIN and the SPEEDGAIN. For more information on these and what they affect please see the answers in this E2E . For some other general guidance on tuning parameters and their affects please…
