Hi
I have query on PWM signal input to DRV8803. Did the IC handle floating point Duty cycle input. I theink it is not working . I got same values for 50.1 to 50.9 and sudden variation for 51. How can i rectify this problem. did the problem is in my MCU side or in driver IC side. I am Driving Proportional flow control valve with PWM input.
for
PWM duty Cycle in % | Flow output in LPM |
50.1 | 1.8 |
50.2 | 1.8 |
50.3 | 1.8 |
50.4 | 1.8 |
50.5 | 1.8 |
50.6 | 1.8 |
50.7 | 1.8 |
50.8 | 18 |
50.9 | 1.8 |
51 | 3.06 |
Thanks and regards
