Basic Operation: CMOS Output (Active Low) 1-1. When power supply voltage (VDD) higher than release voltage (+VDET), transistor transistor provide (high) output. Since transistor Figure OFF, comparator input voltage 1-2. When goes below +VDET, output provides level, long remains above detection voltage -VDET. When falls below -VDET (point Figure 14), transistor becomes transistor becomes OFF, level appears output. this time transistor Figure becomes comparator input voltage changed 1-3. When falls below minimum operating voltage, output becomes undefined, goes when output pulled VDD. 1-4. level appears when rises above minimum operating voltage. level still appears even when surpasses -VDET, long does exceed release voltage +VDET. 1-5. When rises above +VDET (point Figure 14), transistor becomes OFF, transistor becomes appears output after delay time (tD) counted delay circuit.

There limit capacitance external capacitor (CD) long leakage current capacitor ignored against built-in constant current value. Leakage current causes deviation delay time. When leakage current larger than built-in constant current, release takes place.

Detection Voltage (-VDET), Release Voltage (+VDET)
detection voltage (-VDET) voltage which output turns low. This detection voltage varies slightly among products same specification. variation detection voltage between specified minimum (-VDET) Min. maximum (-VDET) Max. called detection voltage range (Refer Figure 18). Example: S-80927CN, detection voltage lies range 2.646(-VDET) 2.754. This means that some S-80927CNs have 2.646 -VDET some have 2.754 release voltage (+VDET) voltage which output turns high. This release voltage varies slightly among products same specification. variation release voltage between specified minimum (+VDET) Min. maximum (+VDET) Max. called release voltage range (Refer Figure 19). range calculated from actual detection voltage (-VDET) product expressed S-80913 S-80914, S80915 S-80960. Example: S-80927CN, release voltage lies range 2.725(+VDET) 2.947. This means that some S-80927CNs have 2.725 +VDET some have 2.947

Oscillation
applications where resistor connected voltage detector input (Figure 21), taking CMOS active product example, through-type current, which generated when output goes from high (release) causes voltage drop equal [through-type current] [input resistance] across resistor. When input voltage drops below detection voltage (-VDET) result, output voltage goes level. this state, through-type current stops resultant voltage drop disappears, output goes from high. through-type current again generated, voltage drop appears, repeatiing process finally induces oscillation.
