Power-on reset circuit
Voltage level sensing power-up reset circuit Patent #: 4717840
AbstractA power-on reset circuit includes a trigger voltage generating circuit which, when activated, causes current from a current source to be steered so as to charge a capacitor. When the voltage on the capacitor reaches a predetermined value, a switchable output stage is switched so as to generate the desired power-on reset signal. The trigger voltage generating circuit is responsive to a threshold voltage which tracks the power supply voltage and which is generated by separate circuitry.
