Current-sensing power-on reset circuit for integrated circuits |
摘要 |
The power-on reset circuit of this invention includes a current-sensing circuit, a pulse-stretching circuit, and a voltage-reference circuit. The voltage-reference circuit consists, for example, of one N-Channel and one P-Channel MOS transistor. The circuit of this invention uses a static voltage reference comprised of CMOS transistors to detect the power-up condition. The circuit of this invention improves detection of a transient power-supply voltage Vcc loss and detects that power-supply voltage transient on both rising and falling edges.
