S-80746AL

The S-80746AL is one member of the 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 opendrain 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.

Features of the S-80746AL are:(1)ultra-low current consumption 1.0 A typ. (VDD=4.5 V); (2)high-precision detection voltage ±2.4%; (3)wide operating voltage range 1.0 to 15 V; (4)good hysteresis characteristics 5% typ.; (5)wide operating temperature range -30 to+80; (6)3 output forms : Nch open-drain, CMOS output active H ,active L; (7)TO-92, SOT-89-3 and SOT-23-5 package. The S-807 Series, in comparison with conventional reset ICs such as the S-805 Series, offers greater detection voltage precision(twice that of conventional units) and lower current consumption (half that of conventional units). These characteristics result in the following advantages over conventional units.

The absolute maximum ratings of the S-80746AL can be summarized as:(1) power supply voltage: 18 V;(2)storage temperature range:-40 to 125;(3) input voltage: Vss0.3 V to Vdd + 0.3 V;(4) output current:50mA;(5)operating temperature range:-30 to +80;(6)power dissipation: 200mW. Through-type current refers to the instantaneous current flow which occurs at the moment a voltage detector output toggles.This current is quite large in devices with CMOS configured outputs, and also occurs to some extent in Nch open-drain configured devices. S-807 Series voltage detectors are specially designed to limit through-type currents and are superior toS-805 Series devices in this respect. (See current consumption characteristics.). In applications where a resistor is connected to the voltage detector input (Figure 11 and 12), the through-type current generated when the output goes from low to high (release) causes a voltage drop equal to [through-type current]*[input resistance] across the resistor. When the input voltage resultantly drops below the detection voltage -VDET, the output voltage returns to its low level.
