摘要：
A power-on reset circuit responds to a power decrease of very short duration by using a delay circuit having a high threshold inverter which reliably detects a voltage as high as a standard threshold voltage as a low voltage when the power supply voltage again begins to increase. A very low current source provides current for driving the power-on reset circuit only when providing a power-on reset signal and draws no current during normal circuit operation.
