CPU reset generator IC
« on: May 14, 2010, 11:54:38 PM »
Someone told me that there is a 3 pin IC available that generates a soft start CPU reset voltage for CPU's, I was wondering if anyone has come across these and knows a part number? I have an Oberheim OB8 with a strange factory mod that I want to ditch in favour of a better reset circuit.

Microchip MCP809 among about a hundred variations-on-the-theme.

But these aren't "soft start" reset devices. They monitor the power rail, and keep their outputs asserted for well after the power-supply has stabilized.

No, that was a fun thread way back, but this time it is an OB8 with a weird factory revision, so I want to bypass it all together with a new chip.
