Hi all, I am currently using 2 IR2110 to drive the MOSFETs in an H-bridgem however, my problem is that the high side never goes down to 0, instead it goes down to 14 V.

These are the waves going into the driver high and low sides:

Here is a schematic of my connection, the values I am using are exactly the same:


Any help will be appreciated.

What are you measuring the high side with reference to, ground ? What is VCC/VDD ? Why do you not show the complete schematic ? Why do you not show scope plots of the output/s you are complaining about ?
Try giving more information in your questions if you want help :)

Ohh looks like you posted something similar before, thats very confusing!
