Hello there, new to Arduino, and am going to use one to control various systems in a car that I am building...please see http://www.roopod.com just the basic stuff...nothing fancy...self canceling directional lights, pwm headlights, Fans and other lights, solenoid valves for a heated Vegetable oil system, and etc.
my question is can I switch this IR3313(S)pbf high side switch with a Arduino pin, or do I need a transistor go between?
datasheet is here:
aplication note here:
it's confusing to me (newby) to understand what the input requirements are.
on the last page of the application note it says, to run it without current feedback (fine with me) you can run it with one wire.
it further says that "when VCC-VIN reaches VIH" it switches on...HUH?
VCC is the supply being switched
VIN is the input signal
VIH is a threshold that says 5.4-6.2v
Please help !
I am just learning this micro-controller stuff, if anyone has bright ideas or better ways to do what I am trying to do please let me know! any contributions will be recognized on my blog http://www.roopod.com
