Part Number: DRV8718-Q1 Dear Expert
When DRV8718 is in non-operational state, t he same voltage as PVDD is measured in GHx and SHx.
In the full bridge application, this phenomenon is expected to cause both ends of the motor to be short-circuited and break…

Then they…
Part Number: DRV8718-Q1 Hi Team,
There is undershoot issue on GH3 when HB3_CTRL is controlled by PWM signal. Please check an attachment and let me know how to resolve or improve this issue, and please share it with me if there is a reference circuit. …
Part Number: DRV8718-Q1 What to do with unused half-bridge SHx? Floating or grounded? If the mos of the unused channel of DRV871x is not attached and SHx is floating, how to ensure that when overvoltage brake occurs, LS4~LS8 will not fail the overvoltage…

Part Number: DRV8718-Q1 Hi
Vin=24V
1. Can you let me know the VCP output voltage when Vin=24V.
2. Can you explain BRAKE pin in detail?
3. SO1, SO2 pins are sensing output. Does this pin need to input serial resistor, 1kohm?
Thanks.
Part Number: DRV8718-Q1 Hi Team,
I used two DRV8718s in my project. When one 8718 has an overcurrent, the other 8718 reports an overcurrent fault. 8718 will incorrectly report overcurrent faults when other drive overcurrent faults occur. I discovered…
Part Number: DRV8718-Q1 Hello,
Here is a question from my customer:
when IN1 and IN2 input the same PWM signal, the GL1 and GL2 outputs have different time delay. The gap is about 1uS when the driver source current is 12mA, and it can be fixed with the…
