Ech voltge detector in the series detects prticulr fixed voltge rnging from 2.2 to 7.0. The voltge detectors consist of highprecision nd low power consumption stndrd voltge source s well s comprtor, Selection Tble Note: Prt No. Detectble oltge Hysteresis Width 7022A ±2% 7024 A ±2% 7027 A ±2% 7030 A ±2% 7033 A ±2% 7036 A ±2% 7039 A ±2% 7044 A ±2% 7050 A ±2% 7070 A ±2% Microcomputer reset Bttery memory bckup Nonvoltile RAM signl storge protectors hysteresis circuit, nd n output driver. CMOS technology ensures low power consumption. Although designed primrily s fixed voltge detectors, these devices cn be used with externl components to detect user specified threshold voltges.
