I'm using the ISP762T:
I have a 12V power source and all I want to do is switch it on and off (via microcontroller) depending if I want to power my 12V circuit or not. That datasheet says present a logic high to turn it on. Easy right? Well, when I present a logic high to the input it works great - ie. 12V supplied to load. When I present a logic low to the input (IN) it supplies around 10V to my load. Why won't it turn off? Anyone help me? thank you thank you in advance.
