Title: Power-on reset circuit
Inventor: MORRILL DAVID P
IPC: H03K17/22
Filed: 1999-10-29
Abstract: PURPOSE: A power-on reset circuit is provided which is less dependent on process vagaries and temperature swings than that of prior reset circuits, is referenced to the more certain low-potential power rail, and enables transmission of a power-on signal at a selectable minimum potential of the high-potential power rail and within a more well-defined range of potentials. CONSTITUTION: A fabrication- and temperature-independent power-on reset circuit for providing improved control over live insertion of integrated circuitry. The reset circuit includes a comparator having an output terminal and two input terminals, one positive and one negative. One of the two terminals is coupled to a first threshold turn-on branch and the other terminal is coupled to a second threshold turn-on branch. Both threshold branches are referenced to ground but they supply different initial potentials to the terminals of the comparator. As a result, one terminal acting as the reference terminal holds the circuit output of the present invention at a potential designed to halt circuit power-on regardless of independent enable control pin signals. The other of the two terminals does not trigger switching of the comparator output until after a common supply power rail reaches a desired potential at initial turn-on. Referencing of the two threshold branches of the circuit to ground ensures that fabrication and temperature vagaries are effectively canceled out.
