Hello,
I want to base my custom PCB project off of VNH5019A-E (details) dual h-bridge boards. I have a couple of questions concerning the layout I currently have:
The MOSFETs I routed with are standard SOT-23 packages, and will generally not be able to conduct more than 2A of current. There are the ones used as reverse-battery protection.
I would like to know 2 things:
1) Will these smaller MOSFETs (shown in pink rectangles) work? I figure they are only useful for reverse-voltage protection. If they will not suit this purpose, what type of MOSFET would you recommend?
2) Is it possible to solder the motor drivers without a reflow oven? I have a hot-air gun, best case scenario. I'm not sure how to proceed with the heat slugs underneath the IC.
Thanks!
