Seiko Instruments Inc. 1 * S-807 Series will be summarized into S-808 Series. HIGH-PRECISION VOLTAGE DETECTOR S-807 Series The S-807 Series is an adjustment-free high-precision voltage detector made using the CMOS process. The output voltage is fixed internally, with an accuracy of ±2.4%. Two output types are available, Nch open- drain and CMOS output (active “H” and “L”), both of which have various product lineups. This series features much lower current consumption and higher detection voltage accuracy than the S-805 Series. Super- miniature package is added for the S-807 Series, the S-807XXSX Series. This small SOT-23-5 style package allows the designer to shrink the size of his finished product. Electrical specs for the S- 807XXSX Series are the same as the standard S-807 Series. Output forms of the S-807XXSX Series are Nch open-drain and CMOS active “L”. Pin Assignment Features • Ultra-low current consumption 1.0 µA typ. (V DD=4.5 V) • High-precision detection voltage ±2.4% • Wide operating voltage range 1.0 to 15 V • Good hysteresis characteristics 5% typ. • Wide operating temperature range -30°C to+80°C • 3 output forms : Nch open-drain, CMOS output active H , active L • TO-92, SOT-89-3 and SOT-23-5 package Applications • Battery checker • Battery backup for memories • Power failure detector • Reset for microcomputer • Store signal detector for non- volatile RAM Top view Top view 1 OUT 2 VDD 3 VSS 1 2 3 Bottom view 1 2 3 1 OUT 2 VDD 3 VSS (1) TO-92 (2) SOT-89-3 (3) SOT-23-5 1 2 3 1 OUT 2 VDD 3 VSS 4NC 5NC 54 Figure 1 |
