\$\begingroup\$ Please tell us what properties you don't understand, the question is otherwise too broad to answer. \$\endgroup\$jippie– jippie2013-02-17 14:52:13 +00:00Commented Feb 17, 2013 at 14:52

You didn't provide too many clues as to what you are interested in... By the way, it's all written in the datasheet you linked. This device is just 2 N-channel FETs in one package, with their drains connected. Nothing fancy. For example you can use it for high-side switching, as its Rdson and voltage range makes it suitable for the task.

\$\begingroup\$ What do you mean that it can be used for high speed switching? \$\endgroup\$john– john2012-10-20 19:51:59 +00:00Commented Oct 20, 2012 at 19:51

\$\begingroup\$ high side. I did not say high speed. High side switching means that given an "ordinary" single supply setup, so the device requiring GND and a positive voltage to operate, this switch can be used to switch the positive voltage to the device. Low side switching in the same setup would mean breaking and connecting the "ground" line to the device. \$\endgroup\$ppeterka– ppeterka2012-10-20 19:53:28 +00:00Commented Oct 20, 2012 at 19:53

\$\begingroup\$ Sorry, but the image is absolutely unreadable, I can't even figure o ut what's what, I'm not even able to find the FETs... You should try and upload it in a higher resolution... \$\endgroup\$ppeterka– ppeterka2012-10-20 20:15:26 +00:00Commented Oct 20, 2012 at 20:15

\$\begingroup\$ I guess I dont have any other choice to share the schematic with you..inorder to nail down the issue. \$\endgroup\$john– john2012-10-20 20:57:41 +00:00Commented Oct 20, 2012 at 20:57
