Part Number:DRV8842
Hi,
In datasheet of DRV8842, there are three decay modes: fast decay, slow decay and mixed decay. I have quesitons need your help as follows:
1. Does "decay" represent the decay of motor's current when PWM signal is low level?
2. What are the advantages and disadvantages of three modes?
3. How to select decay mode based on specific application?
I am waitting your answers, thank you!
