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 10), 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.

Oscillation
applications where resistor connected voltage detector input (Figure 16), taking CMOS active products 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, repeating process finally induces oscillation.

Precautions
S-801 series products, through-type current flows frequency approximately during delay time since internal oscillator circuit counter timer operate voltage release. High impedance input cause oscillation through-type current. When input impedance high, insert capacitor between prevent oscillation. apply electrostatic discharge this that exceeds performance ratings built-in electrostatic protection circuit. CMOS output products S-801 Series, through-type current flows detection release. impedance high, oscillation occur voltage drop through-type current during releasing. When designing mass production using application circuit described herein, product deviation temperature characteristics should taken into consideration. shall bear responsibility patents circuits described herein. claims responsibility disputes arising connection with infringement products including this upon patents owned third party.
