Basic operation: CMOS output (Active “L”) (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 (“H”) at the output. Since the Nch transistor N1 in Figure 14 is OFF, the (RB + RC) • VDD comparator input voltage is . RA + RB + RC (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 15), 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 14 RB • VDD becomes ON, the comparator input voltage is changed to . RA + RB (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 15), the Nch transistor becomes OFF and the Pch transistor becomes ON to provide VDD level at the output.

Perform sufficient evaluation using the actual application to set the constants. Explanation of Terms 1. Detection voltage (−VDET), release voltage (+VDET) The detection voltage (−VDET) is a voltage at which the output turns to “L”. 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 18). Example: For the S-1000C15, the detection voltage lies in the range of 1.485 ≤ (−VDET) ≤ 1.515. This means that some S-1000C15s have 1.485 V for −VDET and some have 1.515 V. The release voltage is a voltage at which the output turns to “H”. 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 19). The range is calculed from the actual detection voltage (−VDET) of a product and is expressed by −VDET × 1.03 ≤ +VDET ≤ −VDET × 1.07. Example: For the S-1000C15, the release voltage lies in the range of 1.530 ≤ (+VDET) ≤ 1.621. This means that some S-1000C15s have 1.530 V for +VDET and some have 1.621 V.

Hysteresis width (VHYS) Figure 19 Release voltage (CMOS output products) The 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 15). The existence of the hysteresis width prevents malfunction caused by noise on input signal. 3. 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 is large in CMOS output products, small in Nch open-drain output products. 4. Oscillation In applications where a resistor is connected to the voltage detector input (Figure 20), taking a CMOS active “L” product for example, the through-type current which is generated when the output goes from “L” to “H” (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 “L” to “H”. The through-type current is then generated again, a voltage drop appears, and repeating the process finally induces oscillation.

Rev.2.3_00 Precautions ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR S-1000 Series • If the input impedance is high, oscillation may occur due to the through-type current etc. In COMS output products, impedance should not be connected to the input pin. In Nch open drain output products, input impedance is recommended to be 800 Ω or less. However be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. • In CMOS output products oscillation may occur when a pull-down resistor is used, and falling speed of the power supply voltage (VDD) is slow near the detection voltage. • 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 products on the circuits described herein. • Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. • 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 by a third party.

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 24, 25 can be easily constructed with the help of the S-1000 series, that has low operating voltage, a high-precision detection voltage and hysteresis.
