Part Number:DRV8871-Q1
Hi team,
Greetings. I have a question about the VM bulk cap of DRV8871-Q1.
The parameter is that VM=12V coming from automotive battery, normal working current=1A, stall current=2.5A.
Duty cycle is 100% only using high or low voltage level to controll.
Can I just use a 1uF ceramic cap here? Is there any drawback?
What if I use 10uF ceramic cap or a bulk cap? Any problems?
Customer said they used 0.1uF cap on VM pin when they used two half bridge chips before, there was no problem.
Look forward to your reply.
Thank you.
Best Regards
Jack Chen
