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 V DD (“H”) at the output. Since the Nch transistor N1 in Figure 14 is OFF, the comparator input voltage is CBA DDCB RRR V)RR(

• + . (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 V DD falls below −VDET (point A in Figure 15), the Nch transistor becomes ON, the Pch transistor becomes OFF, and the V SS level appears at the output. At this time the Nch transistor N1 in Figure 14 becomes ON, the comparator input voltage is changed to BA DDB RR VR
• . (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 V SS level still appears even when the VDD surpasses −VDET, as long as it does not exceed the release voltage +VDET. (5) When the V DD 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.

R is unnecessary for CMOS output products. Figure 17 Caution The above connection diagram and constants do not guarantee correct operation. 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 (+V DET) 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.

ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR Rev.3.1_00 S-1000 Series Seiko Instruments Inc. 17  Precautions

• 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 co nsideration. SII shall not bear any resp onsibility for the products on the circuits described herein.
