9 / 14 page 9/14 XC6109 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 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 input pin voltage falls below the minimum operating voltage range. In CMOS output, for output current, drops in the input pin voltage similarly occur. 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. Note that a rapid and high fluctuation of the input pin voltage may cause a wrong operation. 4. When there is a possibility of which the 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. 5. When N-ch open drain output is used, output voltages VOUT at voltage detection and release are determined by a pull-up resistor tied to the output pin. A resistance value of the pull-up resistor can be selected with referring to the followings. (Refer to Figure 4) During detection, the formula is given as VOUT=Vpull/(1+Rpull/RON) where Vpull is pull-up voltage and RON (*1) is ON resistance of N-ch driver M5 (RON=VDS/IOUT1 from the electrical characteristics table). For example, when VIN=2.0V (*2), RON = 0.5/0.8×10 -3=625Ω(MIN.) and if you want to get VOUT less than 0.1V when Vpull=3.0V, Rpull can be calculated as follows; Rpull=(Vpull /VOUT-1)×RON=(3/0.1-1)×625≒18kΩ Therefore, pull-up resistance should be selected 18kΩ or higher. (*1) VIN is smaller, RON is bigger (*2) For the calculation, the lowest VIN should be used among of the VIN range During release, the formula is given as VOUT=Vpull/(1+Rpull/Roff) where Vpull is pull-up voltage Roff is OFF resistance of N-ch driver M5 (Roff=VOUT/ILEAK=15MΩ from the electrical characteristics table) For examples, if you want to get VOUT larger than 5.99V when Vpull is 6.0V, Rpull can be calculated as follows; Rpull=(Vpull/VOUT-1)×Roff=(6/5.99-1)×15×10 6≒25kΩ Therefore, pull-up resistance should be selected 25kΩ or below.
