XC6108 series is Not Recommended for New Designs. XC6108 Series ETR0205_010b Voltage Detector with Separated Sense Pin & Delay Capacitor Pin ■GENERAL DESCRIPTION The XC6108 series is highly precise, low power consumption voltage detector, manufactured using CMOS and laser trimming technologies. Since the sense pin is separated from power supply, it allows the IC to monitor added power supply. Using the IC with the sense pin separated from power supply enables output to maintain the state of detection even when voltage of the monitored power supply drops to 0V. Moreover, with the built-in delay circuit, connecting the delay capacitance pin to the capacitor enables the IC to provide an arbitrary release delay time. Both CMOS and N-channel open drain output configurations are available. ■APPLICATIONS ■FEATURES ●Microprocessor reset circuitry Highly Accurate : +2% (Detect Voltage≧1.5V) +30mV (Detect Voltage<1.5V) ●Charge voltage monitors Low Power Consumption ●Memory battery back-up switch circuits : 0.6 μA TYP.

XC6108 Series ■OPERATIONAL EXPLANATION A typical circuit example is shown in Figure 1, and the timing chart of Figure 1 is shown in Figure 2 on page 14. ① As an early state, the sense pin is applied sufficiently high voltage (6.0V MAX.) and the delay capacitance (Cd) is charged to the power supply input voltage, (VIN: 1.0V MIN., 6.0V MAX.). While the sense pin voltage (VSEN) starts dropping to reach the detect voltage (VDF) (VSEN>VDF), the output voltage (VOUT) keeps the “High” level (=VIN). * If a pull-up resistor of the XC6108N series (N-ch open drain) is connected to added power supply different from the input voltage pin, the “High” level will be a voltage value where the pull-up resistor is connected. ② When the sense pin voltage keeps dropping and becomes equal to the detect voltage (VSEN =VDF), an N-ch transistor (M1) for the delay capacitance (Cd) discharge is turned ON, and starts to discharge the delay capacitance (Cd). An inverter (Inv.1) operates as a comparator of the reference voltage VIN, and the output voltage changes into the “Low” level (=VSS). The detect delay time [tDF] is defined as time which ranges from VSEN=VDF to the VOUT of “Low” level (especially, when the Cd pin is not connected: tDF0). ③ While the sense pin voltage keeps below the detect voltage, the delay capacitance (Cd) is discharged to the ground voltage (=VSS) level. Then, the output voltage maintains the “Low” level while the sense pin voltage increases again to reach the release voltage (VSEN< VDF +VHYS). ④ When the sense pin voltage continues to increase up to the release voltage level (VDF+VHYS), the N-ch transistor (M1) for the delay capacitance (Cd) discharge will be turned OFF, and the delay capacitance (Cd) will start discharging via a delay resistor (Rdelay). The inverter (Inv.1) will operate as a comparator (Rise Logic Threshold: VTLH=VTCD, Fall Logic Threshold: VTHL=VSS) while the sense pin voltage keeps higher than the detect voltage (VSEN > VDF). ⑤ While the delay capacitance pin voltage (VCD) rises to reach the delay capacitance pin threshold voltage (VTCD) with the sense pin voltage equal to the release voltage or higher, the sense pin will be charged by the time constant of the RC series circuit. Assuming the time to the release delay time (tDR), it can be given by the formula (1). tDR = -Rdelay×Cd×In (1-VTCD / VIN) …(1) * In = a natural logarithm The release delay time can also be briefly calculated with the formula (2) because the delay resistance is 2.0MΩ(TYP.) and the delay capacitance pin voltage is VIN /2 (TYP.) tDR = Rdelay×Cd×0.69…(2) *:Rdelay is 2.0MΩ(TYP.) As an example, presuming that the delay capacitance is 0.68μF, tDR is : 2.0×106×0.68×10-6×0.69=938(ms) * Note that the release delay time may remarkably be short when the delay capacitance (Cd) is not discharged to the ground (=VSS) level because time described in ③ is short. ⑥ When the delay capacitance pin voltage reaches to the delay capacitance pin threshold voltage (VCD=VTCD), the inverter (Inv.1) will be inverted. As a result, the output voltage changes into the “High” (=VIN) level. tDR0 is defined as time which ranges from VSEN=VDF+VHYS to the VOUT of “High” level without connecting to the Cd. ⑦ While the sense voltage is higher than the detect voltage (VSEN > VDF), the delay capacitance pin is charged until the delay capacitance pin voltage becomes the input voltage level. Therefore, the output voltage maintains the “High”(=VIN) level. 12/22 XC6108 series is Not Recommended for New Designs.

Series ■NOTES ON USE 1. Use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent damage to the device. 2. The power supply input pin voltage drops by the resistance between power supply and the VIN pin, and by through current at operation of the IC. At this time, the operation may be wrong if the power supply input pin voltage falls below the minimum operating voltage range. In CMOS output, for output current, drops in the power supply input pin voltage similarly occur. Moreover, in CMOS output, when the VIN pin and the sense pin are short-circuited and used, oscillation of the circuit may occur if the drops in voltage, which caused by through current at operation of the IC, exceed the hysteresis voltage. Note it especially when you use the IC with the VIN pin connected to a resistor. 3. When the setting voltage is less than 1.0V, be sure to separate the VIN pin and the sense pin, and to apply the voltage over 1.0V to the VIN pin. 4. Note that a rapid and high fluctuation of the power supply input pin voltage may cause a wrong operation. 5. Power supply noise may cause operational function errors, Care must be taken to put the capacitor between VIN-GND and test on the board carefully. 6. When there is a possibility of which the power supply input pin voltage falls rapidly (e.g.: 6.0V to 0V) at release operation with the delay capacitance pin (Cd) connected to a capacitor, use a schottky barrier diode connected between the VIN pin and the Cd pin as the Figure 3 shown below. 6. In N channel open drain output, VOUT voltage at detect and release is determined by resistance of a pull up resistor connected at the VOUT pin. Please choose proper resistance values with reffering to Figure 4; During detection : VOUT = Vpull / (1+Rpull / RON) Vpull: Pull up voltage RON(※1):On resistance of N channel driver M3 can be calculated as VDS / IOUT1 from electrical characteristics, For example, when (※2) RON = 0.5 / 0.8×10-3 = 625Ω(MIN.)at VIN=2.0V, Vpull = 3.0V and VOUT ≦0.1V at detect, Rpull= (Vpull /VOUT-1)×RON= (3 / 0.1-1)×625≒18kΩ In this case, Rpull should be selected higher or equal to 18kΩ in order to keep the output voltage less than 0.1V during detection. (※1) RON is bigger when VIN is smaller, be noted. (※2) For calculation, Minimum VIN should be chosen among the input voltage range. During releasing:VOUT = Vpull / (1 + Rpull / Roff) Vpull:Pull up voltage Roff:On resistance of N channel driver M3 is 15MΩ(MIN.) when the driver is off (as to VOUT / ILEAK) For example:when Vpull = 6.0V and VOUT ≧ 5.99V, Rpull = (Vpull / VOUT-1)×Roff = (6/5.99-1)×15×106 ≒25kΩ In this case, Rpull should be selected smaller or equal to 25kΩ in order to obtain output voltage higher than 5.99V during releasing.
