I have been looking into some of the offerings TI has for supervisory = circuits, with the idea if creating a power supply for my project that = will delay startup. However, I am not clear on how you could tie these = devices into a regulator. Basically, I would like to design a power = supply that will shut down power to the whole board if any transients = are detected and reset everything (lcd, eeproms, etc.) on power up. The = design is going to be used in a homebuilt aircraft and I want my project = to shut itself off when a transient is detected (starting the engine) = and come back up automatically in a second or two after things = stabilize. Can anyone point me in the right direction? -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
