Description

The S-8051ANB is one member of the S-805 series. The S-805 Series is a non-adjusting voltage detector made using a CMOS process. The detection voltage is fixed internally. The voltage detectors are composed of a high-precision and low power consumption standard voltage source, a comparator, a hysteresis circuit, and an output driver. Output forms are Nch open-drain and CMOS output, both of which have various product line ups. Since the S-805 Series needs a typical power consumption of 1.4 A, much lower than other voltage monitoring ICs,  battery-powered portable equipment can have a higher capacity and a longer service life.

Features of the S-8051ANB are: (1)high-stable standard voltage source built-in(0.8 V typ.); (2)hysteresis characteristic(S-8054HN, S-8054HN-CB-X:200mV typ.); (3)good temperature characteristic of detection voltage  (S-8051ANB, S-8051ANB-NA-X:±0.13 mV/ typ.); (4)TO-92 or mini-power mold plastic packages are available; (5)low power consumption(Vdd=1.5 V:1.4 A typ); (6)low resetting output minimum guarantee voltage(S-8051ANB, S-8051ANB-NA-X :0.9 V typ). 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. (See current consumption characteristics.)

The absolute maximum ratings of the S-8051ANB can be summarized as:(1) power supply voltage: 12.0 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:-20 to +70;(6)power dissipation: 200mW. In applications where a resistor is connected to the voltage detector input (Figure 14 and 15),the through-type current generated when the output goes from low to high (release) causes a voltage drop equal to [through-type current] x (input resistance] across the resistor. When the input voltage resultantly drops below the detection voltage-Vdet, the output voltage returns to its low level.  In this state, the through-type current---and its resultant voltage drop--have disappeared, and the output goes back from low to high. Again, a through-type current is generated, a voltage drop appears, and the process repeats. Oscillation refers to this unstable condition.
