Part Number:DRV8842
Hi
The customer concerns about the capacitor that is connected at CP1 and CP2 and VCP and V3P3OUT.
That is "How much max voltage should we estimate at the following capacitor?" and "How much capacitor is it acceptable for the capacitor? (+/- 50%? or less?)"
1. CP1 and CP2 : it should be VM voltage at least. And it need 0.01uF +/-50% accetable. (We need to consider DC bias specifications)
2. VCP : the charge pump voltag is ~11V. So that, 16V need at least. And 0.1uF +/-50% at least.
3. V3P3OUT: The internal LDO output is 3.3V. It is mentioned at datasheet as 0.47uF and 6.3V. Why does it need 6.3V? And how much does it need for this capacitor ? +/- 50% is needed ?
I referenced to the following post.
