Hi TI,
1.Do you have the tolerance of driving time like one cycle or half cycle? We find the waveform is different if we drive a very shot time like 2~8ms.(Vibrator operation frequency is 170Hz)

Hi Ivan,
Correct my question.
My question is we're using open loop to drive our vibrator now,and also enable auto-break for breaking.
1.As I know, when using auto-break,DRV2624 will change to closed loop to break the vibrator, but since we use open loop(170Hz),the break frequency(maybe 160Hz) will not the same with operation frequency, is this will cause any problem like increase the breaking time or some side effect?
2.What time does DRV2624 need for start-up and breaking?
3.Attach photo is using the same DRV2624 with same vibrator but the result show the different breaking pattern, is it a normal behavior?
Hi Ivan,
Hi Ivan,
We have a issue on the device that when we enable two vibration which are 25ms with 0.9v(OD_LCAMP) and 10ms with 1.8v(OD_CLAMP) in sequence mode, and there is 100ms between this two vibration.It can't stop the vibration after the first vibration
From PWM waveform,the DRV2624 is keep doing breaking during the 100ms, is there any clue we can check on this issue?or any factor cause this issue?
