S-801

Rev.3.3_00 ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (INTERNAL DELAY TIME SETTING) S-801 Series The S-801 Series is a series of high-precision voltage detectors with a built-in delay time generator of fixed time developed using CMOS process. The detection voltage is fixed internally, with an accuracy of ±2.0 %. Internal oscillator and counter timer can delay the release signal without external parts. Three delay times 50 ms, 100 ms, and 200 ms are available. Two output forms, Nch open-drain and CMOS output, are available. Features • • • • • • • • • 1.3 μA typ.

Basic Operation: CMOS Output (Active Low) 1-1. 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 (RB + RC) • VDD Nch transistor N1 in Figure 10 is OFF, the comparator input voltage is . RA + RB + RC 1-2. When the VDD goes below +VDET, the output provides the VDD level, as long as VDD remains above the detection voltage (–VDET). When the VDD falls below –VDET (point A in Figure 11), 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 10 becomes ON, the comparator RB • VDD . input voltage is changed to RA + RB 1-3. When the VDD falls below the minimum operating voltage, the output becomes undefined, or goes to VDD when the output is pulled up to VDD. 1-4. The VSS level appears when VDD rises above the minimum operating voltage. The VSS level still appears even when VDD surpasses the –VDET, as long as it does not exceed the release voltage +VDET. 1-5. When VDD rises above +VDET (point B in Figure 11), the Nch transistor becomes OFF and the Pch transistor becomes ON to provide VDD at the output.

Delay Circuit 2-1. Delay Time The delay circuit delays the output signal from the time at which the power voltage (VDD) exceeds the release voltage (+VDET) when VDD is turned on. The output signal is not delayed when the VDD goes below the detection voltage (–VDET). (Refer to Figure 11.) The delay time (tD) is a fixed value that is determined by a built-in oscillation circuit and counter. 2-2. DS Pin (ON/OFF Switch Pin for Delay Time) The DS pin should be connected to Low or High. When the DS pin is High, the output delay time becomes short since the output signal is taken from the middle of counter circuit (Refer to Figure 16). 3. Other Characteristics 3-1.

Detection Voltage (–VDET), Release 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 specified minimum (–VDET) Min. and the maximum (–VDET) Max. is called the detection voltage range (Refer to Figure 14). e.g. For the S-80122AN, the detection voltage lies in the range of 2.156 ≤ (–VDET) ≤ 2.244. This means that some S-80122ANs have 2.156 V for –VDET and some have 2.244 V. 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 specified minimum (+VDET) Min. and the maximum (+VDET) Max. is called the release voltage range (Refer to Figure 15). e.g. For the S-80122AN, the release voltage lies in the range of 2.186 ≤ (+VDET) ≤ 2.344. This means that some S-80122ANs have 2.186 V for +VDET and some have 2.344 V. VDD Detection voltage (−VDET) Max. (−VDET) Min. Detection voltage range VDD Release voltage (+VDET) Max. (+VDET) Min.

Seiko Instruments Inc. 17 ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (INTERNAL DELAY TIME SETTING) Rev.3.3_00 S-801 Series 2. Hysteresis Width (VHYS) Hysteresis width is the voltage difference between the detection voltage and the release voltage (The voltage at point B−The voltage at point A=VHYS in Figure 11). The existence of the hysteresis width prevents malfunction caused by noise on input signal. 3. Delay Time (tD) Delay time is a time internally measured from the instant at which input voltage to the VDD pin exceeds the release voltage (+VDET) to the point at which the output of the OUT pin inverts. The delay time is fixed in each series distinguished by A, B and C. S-801xxAx series: typ. 50 ms S-801xxBx series: typ. 100 ms S-801xxCx series: typ. 200 ms The output of the OUT pin can be inverted in a short delay time (tD2) by setting the DS pin High (Refer to Figure 16).

Through-type Current The through-type current refers to the current that flows instantaneously at the time of detection and release of a voltage detector. The through-type current flows at a frequency of 20 kHz during release delay time since the internal logic circuit operates. 18 Seiko Instruments Inc. ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (INTERNAL DELAY TIME SETTING) Rev.3.3_00 S-801 Series 5. Oscillation In applications where a resistor is connected to the voltage detector input (Figure 17), taking a CMOS active low products 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] × [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. The through-type current is again generated, a voltage drop appears, and repeating the process finally induces oscillation. VDD RA VIN S-801 RB VSS OUT Figure 17 Example for Bad Implementation of Input Voltage Divider Precautions • In the S-801 series products, the through-type current flows at a frequency of 20 kHz approximately during the delay time since the internal oscillator circuit and counter timer operate at voltage release. High impedance in the input may cause oscillation by the through-type current. When the input impedance is high, insert a capacitor between VDD pin and VSS pin to prevent oscillation. • Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. • In CMOS output products of the S-801 Series, the through-type current flows at detection and release. If the impedance is high, oscillation may occur due to the voltage drop by the through-type current during releasing. • When designing for mass production using an application circuit described herein, the product deviation and temperature characteristics should be taken into consideration. SII shall not bear any responsibility for the patents on the circuits described herein. • SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of the products including this IC upon patents owned a third party.

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 22 to 23 can be easily constructed with the help of the S-801 series that has low operating voltage, a high-precision detection voltage, hysteresis, and a built-in delay circuit.
