Abstract
A power-on reset circuit produces a reset signal output configured by an upper trip-point in an input hysteresis characteristic of the circuit. The upper trip-point is configured by resistances of a first pair of resistors coupled in series at an internal voltage reference node. A temperature coefficient of the upper trip-point is configured by resistance values of a second pair of resistors where each resistor is coupled with a corresponding switching device with an associated switching threshold. A magnitude of the input hysteresis characteristic is configured by resistances of a third pair of resistors in series. The magnitude of hysteresis is configured independent of configuring either the level or the temperature coefficient of the upper trip-point.
