1.5ms power on delay
I need a ckt that has this condition "CPU_+1.2V should supply 1.5ms earlier than CPU_+3.3V" If I have 3.3V from power supply and during Power ON I need to delay it with 1.5ms to supply to CPU as CPU_+3.3V as a requirement of CPU POWER MANAGEMENT. I was looking for an IC that is not microcontroller to avoid increase of budget for the project. (i.e. LM555 timer but what kind of circuit? I only get tens, hundreds of increment. and not 0.5ms)...
