Part Number: DRV8839
Hello Sir,
Good Morning,
Task : PWM based Motor Drive using Motor Driver IC
As above mention project we working, we are facing issue of MOTOR Vibration while motor operate at 100% duty cycle.
MCU:
a> PWM output Freq : 2 Khz
b> Duty Cycle : 100%
MOTOR Specification :
a> Voltage : 3 Vdc
b> Current : 0.15 A
We attach PWM Driver IC configuration,
We test with different PWM freq. such as 1Khz, 5Khz, 10Khz, 15Khz, 20Khz but get same issue.
Motor Only vibrate at 100% duty cycle.
Need Help , I am not get any idea what is issue.
Thanks & Regards
