Detection voltage (VDET) 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 (VDET min.) and the maximum (VDET max.) 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  VDET  1.822 V. This means that some S-1002Cx18 have VDET = 1.778 V and some have VDET = 1.822 V. 2. Release voltage (VDET) 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 (VDET min.) and the maximum (VDET max.) is called the release voltage range (Refer to Figure 17). The range is calculated from the actual detection voltage (VDET) of a product and is in the range of VDET  1.03  VDET  VDET  1.07. Example: For the S-1002Cx18, the release voltage is either one in the range of 1.832 V  VDET  1.949 V. This means that some S-1002Cx18 have VDET = 1.832 V and some have VDET = 1.949 V.

Hysteresis width (VHYS) 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 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.

Basic operation 1. 1 S-1002 Series NA / NB type (1) When the power supply voltage (VDD) is the minimum operation voltage or higher, and the SENSE pin voltage (VSENSE) is the release voltage (VDET) or higher, the Nch transistor is turned off to output VDD ("H") when the output is pulled up. Since the Nch transistor (N1) is turned off, the input voltage to the comparator is (RB  RC )  VSENSE . RA  RB  RC (2) Even if VSENSE decreases to VDET or lower, VDD is output when VSENSE is higher than the detection voltage (VDET). When VSENSE decreases to VDET or lower (point A in Figure 22), the Nch transistor is turned on. And then VSS ("L") is output from the OUT pin after the elapse of the detection delay time (tDET).

At this time, N1 is turned on, and the input voltage to the comparator is RA  RB (3) Even if VSENSE further decreases to the IC's minimum operation voltage or lower, the output from the OUT pin is stable when VDD is minimum operation voltage or higher. (4) Even if VSENSE exceeds VDET, VSS is output when VSENSE is lower than VDET. (5) When VSENSE increases to VDET or higher (point B in Figure 22), the Nch transistor is turned off.

Rev.1.1_03 SENSE pin 2. 1 Error when detection voltage is set externally By connecting a node that was resistance-divided by the resistor (RA) and the resistor (RB) to the SENSE pin as seen in Figure 25, the detection voltage can be set externally. For conventional products without the SENSE pin, RA cannot 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 RA is large, problems such as oscillation or larger error in the hysteresis width may occur. In the S-1002 Series, RA and RB are 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 (RSENSE) that will occur. Although RSENSE in the S-1002 Series is large (5 M min.) to make the error small, RA and RB should be selected such that the error is within the allowable limits. 2. 2 Selection of RA and RB In Figure 25, the relation between the external setting detection voltage (VDX) and the actual detection voltage (VDET) is ideally calculated by the equation below. VDX = VDET  (1  RA RB ) ··· (1) However, in reality there is an error in the current flowing through RSENSE. When considering this error, the relation between VDX and VDET is calculated as follows. RA RB || RSENSE ) RA  = VDET  1  RB  RSENSE   RB  RSENSE   RA RA = VDET  (1  R )  R  VDET B SENSE VDX = VDET  (1  ··· (2) RA . By using equations (1) and (2), the error is calculated as VDET  R SENSE The error rate is calculated as follows by dividing the error by the right-hand side of equation (1). RA  RB RA || RB  100 [%] = R  100 [%] RSENSE  (RA  RB) SENSE ··· (3) As seen in equation (3), the smaller the resistance values of RA and RB compared to RSENSE, the smaller the error rate becomes. Also, the relation between the external setting hysteresis width (VHX) and the hysteresis width (VHYS) is calculated by equation below. Error due to RSENSE also occurs to the relation in a similar way to the detection voltage. VHX = VHYS  (1  RA RB ) ··· (4) RA VDX VDET VDD SENSE OUT RSENSE RB Figure 25 Caution 18 VSS Detection Voltage External Setting Circuit If RA and RB are large, the SENSE pin input impedance becomes higher and may cause a malfunction due to noise. In this case, connect a capacitor between the SENSE pin and the VSS pin. VOLTAGE DETECTOR WITH SENSE PIN S-1002 Series Rev.1.1_03 2. 3 Power on sequence Apply power in the order, the VDD pin then the SENSE pin. As seen in Figure 26, when VSENSE  VDET, the OUT pin output (VOUT) rises and the S-1002 Series becomes the release status (normal operation). VDD VDET VSENSE tRESET VOUT Figure 26 Caution 2. 4 If power is applied in the order the SENSE pin then the VDD pin, an erroneous release may occur even if VSENSE  VDET. Precautions when shorting between the VDD pin and the SENSE pin 2. 4. 1 Input resistor Do not connect the input resistor (RA) 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 RA will cause a drop in VSENSE at the time of release. At that time, oscillation may occur if VSENSE  VDET. RA VDD OUT SENSE VDD VSS Figure 27 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. 19 VOLTAGE DETECTOR WITH SENSE PIN S-1002 Series 2. 5 Rev.1.1_03 Malfunction when VDD falls As seen in Figure 28, note that if the VDD pin voltage (VDD) drops steeply below 1.2 V when VDET  VSENSE  VDET, erroneous detection may occur. When VDD_Low  1.2 V, erroneous detection does not occur. When VDD_Low  1.2 V, the more the VDD falling amplitude increases or the shorter the falling time becomes, the easier the erroneous detection. Perform thorough evaluation in actual application.

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.
