18 / 33 page ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (INTERNAL DELAY TIME SETTING) S-801 Series Rev.3.3_00 18 Seiko Instruments Inc. 2. Hysteresis Width (VHYS) Hysteresis width is the voltage difference between the detection voltage and the release voltage (The voltage at point B −The voltage at point A=V HYS in Figure 11). The existence of the hysteresis width prevents malfunction caused by noise on input signal. 3. Delay Time (tD) Delay time is a time internally measured from the instant at which input voltage to the VDD pin exceeds the release voltage ( +V DET) to the point at which the output of the OUT pin inverts. The delay time is fixed in each series distinguished by A, B and C. S-801xxAx series: typ. 50 ms S-801xxBx series: typ. 100 ms S-801xxCx series: typ. 200 ms The output of the OUT pin can be inverted in a short delay time (tD2) by setting the DS pin High (Refer to Figure 16). tD2 tD1 VDD at DS =”H” OUT V +V DET Figure 16 4. Through-type Current The through-type current refers to the current that flows instantaneously at the time of detection and release of a voltage detector. The through-type current flows at a frequency of 20 kHz during release delay time since the internal logic circuit operates. |
