Rev.2.0_31 HIGH-PRECISION SMALL-PACKAGE VOLTAGE DETECTOR
S-808xxC Series
The S-808xxC series is a series of high-precision voltage detectors developed using CMOS process. The detection voltage is fixed internally with an accuracy of 2.0%. Two output forms, Nch open-drain and CMOS output, are available. Ultra-low current consumption and miniature package lineup can meet demand from the portable device applications.
I Features
* Ultra-low current consumption 1.3 A Typ. (at VDD=1.5 V) (Products with detection voltage of 1.4 V Typ. or less) 0.8 A Typ. (at VDD=3.5 V) (Products with detection voltage of 1.5 V Typ. or more) * High-accuracy detection voltage 2.0 % * Operating voltage range 0.65 V to 5.0 V (Products with detection voltage of 1.4 V Typ. or less) 0.95 V to 10.0 V (Products with detection voltage of 1.5 V Typ. or more) * Hysteresis characteristics 5 % typ. * Detection voltage 0.8 V to 6.0 V (0.1 V step) * Output form Active low CMOS output or active low Nch open-drain
I Applications
* Power monitor for portable equipment such as note book computers, digital cameras, PDA, and cellular phones. * Constant voltage power monitor for cameras, video equipment and communication devices. * Power monitor for microcomputers and reset for CPUs. * Battery checker * Detection of power failure

I Definition of Terms
1. Detection voltage (-VDET) - The detection voltage (-VDET) is a voltage at which the output turns to low. The detection voltage varies slightly among products of the same specification. The variation of detection voltage between the minimum [(-VDET)min.] and the maximum [(-VDET)max.] is called the detection voltage range (See Figure 11). Example : For the S-80815CN, the detection voltage lies in the range of 1.470 (-VDET) 1.530. This means that some S-80815CNs have 1.470 V for -VDET and some have 1.530 V.

2. Release voltage (+VDET) +
Rev.2.0_31
The release voltage (+VDET) is a voltage at which the output turns to high. The release voltage varies slightly among products of the same specification. The variation of release voltages between the minimum [(+VDET)min.] and the maximum [(+VDET)max.] is called the release voltage range (See Figure 12). The range is calculed from the actual detection voltage -VDET of a product and is expressed by -VDET x1.03 +VDET -VDET x1.08. Example : For the S-80815CN, the release voltage lies in the range of 1.514 (+VDET) 1.652. This means that some S-80815CNs have 1.514 V for +VDET and some have 1.652 V. Remark Although the detection voltage and release voltage overlap in the range of 1.514 V to 1.530 V, +VDET is always larger than -VDET.

3. Hysteresis width (VHYS) The hysteresis width is the voltage difference between the detection voltage and the release voltage (See Figure 16). The existence of the hysteresis width avoids malfunction caused by noise on input signal. 4. Through-type current The through-type current in a voltage detector is the current which flows instantaneously at the time of detection and release of a voltage detector. The through-type current is large in CMOS output products, small in Nch open-drain output products. 5. Oscillation In applications where a resistor is connected to the voltage detector input (Figure 13), taking a CMOS active low product for example, the through-type current which is 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 drops below the detection voltage -VDET as a result, the output voltage goes to low level. In this state, the through-type current stops and its resultant voltage drop disappears, and the output goes from low to high. A through-type current is again generated, a voltage drop appears, and oscillation is finally induced by repeating the process.

(1) When the power supply voltage VDD is higher than the release voltage +VDET, the Nch transistor is OFF and the Pch transistor is ON to provide VDD (high) at the output. Since the Nch transistor N1 in Figure 15 is OFF, the comparator input voltage is (RB+RC)/(RA+RB+RC)xVDD. (2) When the VDD goes below +VDET, the output provides the VDD level, as long as the VDD remains above the detection voltage -VDET. When the VDD falls below -VDET (point A in Figure 16), the Nch transistor becomes ON, the Pch transistor becomes OFF, and the VSS level appears at the output. At this time the Nch transistor N1 in Figure 15 becomes ON, the comparator input voltage is changed to RB/(RA+RB)xVDD. (3) When the VDD falls below the minimum operating voltage, the output becomes undefined, or goes to the VDD when the output is pulled up to the VDD. (4) The VSS level appears when the VDD rises above the minimum operating voltage. The VSS level still appears even when the VDD surpasses -VDET, as long as it does not exceed the release voltage +VDET. (5) When the VDD rises above +VDET (point B in Figure 16), the Nch transistor becomes OFF and the Pch transistor becomes ON to provide VDD level at the output. 2.

I Application Circuit Examples
1. Microcomputer reset circuits If the power supply voltage to a microcomputer falls below the specified level, an unspecified operation may be performed or the contents of the memory register may be lost. When power supply voltage returns to normal, the microcomputer needs to be initialized before normal operations can be done. Reset circuits protect microcomputers in the event of current being momentarily switched off or lowered. Reset circuits shown in Figures 20 and 21 can be easily constructed with the help of the S-808xxC series, since the detector has low operating voltage, a high-precision detection voltage and hysteresis.

Figure 22
Remark 1. Resistor R should be 75 k or less to avoid oscillation. 2. Diode Di instantaneously discharges the charge stored in the capacitor C at the power falling,Di can be removed when the delay of the falling time is not important.

Figure 23 Remark When the power rises sharply as shown in the Figure 24 left, the output may goes to the high level for an instant in the undefined region where the output voltage is undefined since the power voltage is less than the minimum operation voltage.

HIGH-PRECISION SMALL PACKAGE VOLTAGE DETECTOR S-808xxC Series
3. Change of detection voltage In Nch open-drain output products of the S-808xxC series, detection voltage can be changed using resistance dividers or diodes as shown in Figures 25 and 26. In Figure 25 hysteresis width also changes.

Detection voltage= RA+RB * -VDET RB Hysterisis Width= RA+RB * VHYS RB
Remark 1. If RA and RB are large, the hysteresis width may be larger than the value given by the above equation due to the through-type current (which flows slightly in an Nch open-drain product). 2. RA should be 75 k or less to avoid oscillation.
Detection voltage=Vf1+Vf2+(-VDET)

Caution The above connection diagram and constants do not guarantee correct operation. Perform sufficient evaluation using the actual application to set the constants.
I Precautions
* In CMOS output products of the S-808xxC series, the short-circuit current flows at the detection and the release. If the input impedance is high, oscillation may occur due to the voltage drop by the short-circuit current during releasing. * Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. * When designing for mass production using an application circuit described herein, parts deviation and temperature characteristics should be taken into consideration. Seiko Instruments Inc. shall not bear any responsibility for the patents on the circuits described herein.
