Rev.1.1_03

The S-1002 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed

internally with an accuracy of 1.0% (V_DET(S) 2.2 V). It operates with current consumption of 500 nA typ.

Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even

if the SENSE pin falls to 0 V.

Two output forms Nch open-drain output and CMOS output are available.

 Explanation of Terms

1. Detection voltage (V_DET

)

The detection voltage is a voltage at which the output in Figure 18 or Figure 19 turns to "L". The detection voltage

varies slightly among products of the same specification. The variation of detection voltage between the specified

minimum (V_DETmin.) and the maximum (V_DETmax.) is called the detection voltage range (Refer to Figure 16).

Example: In the S-1002Cx18, the detection voltage is either one in the range of 1.778 V  V_DET 1.822 V.

This means that some S-1002Cx18 have V_DET= 1.778 V and some have V_DET= 1.822 V.

2. Release voltage (V_DET

)

The release voltage is a voltage at which the output in Figure 18 or Figure 19 turns to "H". The release voltage

varies slightly among products of the same specification. The variation of release voltage between the specified

minimum (V_DETmin.) and the maximum (V_DETmax.) is called the release voltage range (Refer to Figure 17). The

range is calculated from the actual detection voltage (V_DET) of a product and is in the range of V_DET 1.03 

V_DET V_DET 1.07.

Example: For the S-1002Cx18, the release voltage is either one in the range of 1.832 V  V_DET 1.949 V.

This means that some S-1002Cx18 have V_DET= 1.832 V and some have V_DET= 1.949 V.

3. Hysteresis width (V_HYS

)

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 = V_HYSin "Figure 22 Timing Chart of S-1002 Series NA / NB Type" and "Figure

24 Timing Chart of S-1002 Series CA / CB Type"). Setting the hysteresis width between the detection voltage

and the release voltage, prevents malfunction caused by noise on the input voltage.

4. Feed-through current

The feed-through current is a current that flows instantaneously to the VDD pin at the time of detection and release

of a voltage detector. The feed-through current is large in CMOS output product, small in Nch open-drain output

product.

5. Oscillation

In applications where an input resistor is connected (Figure 20), taking a CMOS output (active "L") product for

example, the feed-through current which is generated when the output goes from "L" to "H" (at the time of release)

causes a voltage drop equal to [feed-through current]  [input resistance]. Since the VDD pin and the SENSE pin

are shorted as in Figure 20, the SENSE pin voltage drops at the time of release. Then the SENSE pin voltage

drops below the detection voltage and the output goes from "H" to "L". In this status, the feed-through current stops

and its resultant voltage drop disappears, and the output goes from "L" to "H". The feed-through current is then

generated again, a voltage drop appears, and repeating the process finally induces oscillation.

2. SENSE pin

2. 1 Error when detection voltage is set externally

By connecting a node that was resistance-divided by the resistor (R_A) and the resistor (R_B) to the SENSE pin as

seen in Figure 25, the detection voltage can be set externally.

For conventional products without the SENSE pin, R_Acannot be too large since the resistance-divided node must

be connected to the VDD pin. This is because a feed-through current will flow through the VDD pin when it goes

from detection to release, and if R_Ais large, problems such as oscillation or larger error in the hysteresis width may

occur.

In the S-1002 Series, R_Aand R_Bare easily made larger since the resistance-divided node can be connected to the

SENSE pin through which no feed-through current flows. However, be careful of error in the current flowing through

the internal resistance (R_SENSE) that will occur.

Although R_SENSEin the S-1002 Series is large (5 M min.) to make the error small, R_Aand R_Bshould be selected

such that the error is within the allowable limits.

2. 2 Selection of R_Aand R_B

In Figure 25, the relation between the external setting detection voltage (V_DX) and the actual detection voltage

(V_DET) is ideally calculated by the equation below.

However, in reality there is an error in the current flowing through R_SENSE

When considering this error, the relation between V_DXand V_DETis calculated as follows.

As seen in equation (3), the smaller the resistance values of R_Aand R_Bcompared to R_SENSE, the smaller the error

rate becomes.

Also, the relation between the external setting hysteresis width (V_HX) and the hysteresis width (V_HYS) is calculated

by equation below. Error due to R_SENSEalso occurs to the relation in a similar way to the detection voltage.

2. 4 Precautions when shorting between the VDD pin and the SENSE pin

2. 4. 1 Input resistor

Do not connect the input resistor (R_A) when shorting between the VDD pin and the SENSE pin.

A feed-through current flows through the VDD pin at the time of release. When connecting the circuit shown as

Figure 27, the feed-through current of the VDD pin flowing through R_Awill cause a drop in V_SENSEat the time of

release.

At that time, oscillation may occur if V_SENSE V_DET

.

2. 4. 2 Parasitic resistance and parasitic capacitance

Due to the difference in parasitic resistance and parasitic capacitance of the VDD pin and the SENSE pin,

power may be applied to the SENSE pin first.

Note that an erroneous release may occur if this happens (refer to "2. 3 Power on sequence").

Caution In CMOS output product, make sure that the VDD pin input impedance does not become too

high, regardless of the above. Since a feed-through current is large, a malfunction may occur if

the VDD pin voltage changes greatly at the time of release.

2. 5 Malfunction when V_DDfalls

As seen in Figure 28, note that if the VDD pin voltage (V_DD) drops steeply below 1.2 V when V_DET V_SENSE

V_DET, erroneous detection may occur.



When V_{DD_Low} 1.2 V, erroneous detection does not occur.

When V_{DD_Low} 1.2 V, the more the V_DDfalling amplitude increases or the shorter the falling time becomes, the

easier the erroneous detection.

Perform thorough evaluation in actual application.

 Precautions

 Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic

protection circuit.

 In CMOS output product of the S-1002 Series, the feed-through current flows at the time of detection and release. If

the VDD pin input impedance is high, malfunction may occur due to the voltage drop by the feed-through current

when releasing.

 In CMOS output product, oscillation may occur if a pull-down resistor is connected and falling speed of the SENSE

pin voltage (V_SENSE) is slow near the detection voltage when the VDD pin and the SENSE pin are shorted.

 When designing for mass production using an application circuit described herein, the product deviation and

temperature characteristics of the external parts should be taken into consideration. ABLIC Inc. shall not bear any

responsibility for patent infringements related to products using the circuits described herein.

 ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by

products including this IC of patents owned by a third party.

 Application Circuit Examples

1. Microcomputer reset circuits

In microcomputers, when the power supply voltage is lower than the minimum operation voltage, an unspecified

operation may be performed or the contents of the memory register may be lost. When power supply voltage

returns to the normal level, the microcomputer needs to be initialized. Otherwise, the microcomputer may

malfunction after that. Reset circuits to protect microcomputer in the event of current being momentarily switched

off or lowered.

Using the S-1002 Series which has the low minimum operation voltage, the high-accuracy detection voltage and

the hysteresis width, reset circuits can be easily constructed as seen in Figure 35 and Figure 36.

2. Change of detection voltage

If there is not a product with a specified detection voltage value in the S-1002 Series, the detection voltage can be

changed by using a resistance divider or a diode, as seen in Figure 37 to Figure 40.
