(A condition of high impedance exists with N-ch open drain output configurations.) ② When input voltage (VIN) falls below detect voltage (VDF), output voltage (VOUT) will be equal to the ground voltage (VSS) level. ③ When input voltage (VIN) falls to a level below that of the minimum operating voltage (VMIN), output will become unstable. In this condition, VIN will equal the pulled-up output (should output be pulled-up.) ④ When input voltage (VIN) rises above the ground voltage (VSS) level, output will be unstable at levels below the minimum operating voltage (VMIN). Between the VMIN and detect release voltage (VDR) levels, the ground voltage (VSS) level will be maintained. ⑤ When input voltage (VIN) rises above detect release voltage (VDR), output voltage (VOUT) will be equal to VIN. (A condition of high impedance exists with N-ch open drain output configurations.) ⑥ The difference between VDR and VDF represents the hysteresis range. ●Timing Chart 4/16 XC61G Series ■NOTES ON USE 1. Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent damage to the device. 2. When a resistor is connected between the VIN pin and the input with CMOS output configurations, oscillation may occur as a result of voltage drops at RIN if load current (IOUT) exists. (refer to the Oscillation Description (1) below) 3. When a resistor is connected between the VIN pin and the input with CMOS output configurations, irrespective of N-ch output configurations, oscillation may occur as a result of through current at the time of voltage release even if load current (IOUT) does not exist. (refer to the Oscillation Description (2) below ) 4. With a resistor connected between the VIN pin and the input, detect and release voltage will rise as a result of the IC's supply current flowing through the VIN pin. 5. In order to stabilize the IC's operations, please ensure that VIN pin's input frequency's rise and fall times are more than several μ sec / V. 6. Please use N-ch open drains configuration, when a resistor RIN is connected between the VIN pin and power source. In such cases, please ensure that RIN is less than 10kΩ and that C is more than 0.1μF. ●Oscillation Description (1) Output current oscillation with the CMOS output configuration When the voltage applied at IN rises, release operations commence and the detector's output voltage increases. Load current (IOUT) will flow at RL. Because a voltage drop (RIN x IOUT) is produced at the RIN resistor, located between the input (IN) and the VIN pin, the load current will flow via the IC's VIN pin. The voltage drop will also lead to a fall in the voltage level at the VIN pin. When the VIN pin voltage level falls below the detect voltage level, detect operations will commence. Following detect operations, load current flow will cease and since voltage drop at RIN will disappear, the voltage level at the VIN pin will rise and release operations will begin over again. Oscillation may occur with this " release - detect - release " repetition. Further, this condition will also appear via means of a similar mechanism during detect operations. (2) Oscillation as a result of through current Since the XC61G series are CMOS IC S, through current will flow when the IC's internal circuit switching operates (during release and detect operations). Consequently, oscillation is liable to occur as a result of drops in voltage at the through current's resistor (RIN) during release voltage operations. (refer to Figure 3 ) Since hysteresis exists during detect operations, oscillation is unlikely to occur. 5/16 XC61G Series ■TEST CIRCUITS 6/16 XC61G Series ■TYPICAL PERFORMANCE CHARACTERISTICS ●Low Voltage 7/16 XC61G Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) ●Low Voltage (Continued) 8/16 XC61G Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) ●Standard Voltage 9/16 XC61G Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) ●Standard Voltage (Continued) 10/16 XC61G Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) ●Standard Voltage (Continued) 11/16 XC61G Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) ●Standard Voltage (Continued) 12/16 XC61G Series ■PACKAGING INFORMATION ●USP-3 13/16 XC61G Series ■REFERENCE PATTERN LAYOUT DIMENSIONS ●USP-3 Note: Recommended metal mask design 14/16 XC61G Series ■MARKING RULE ●USP-3 ①Represents integer of output voltage and detect voltage CMOS Output (XC61GC series) MARK CONFIGURATION A CMOS B CMOS C CMOS D CMOS E CMOS F CMOS G CMOS N-channel Open Drain Output (XC61GN series) MARK CONFIGURATION K N-ch L N-ch M N-ch N N-ch P N-ch R N-ch S N-ch ②Represents decimal number of detect voltage MARK 0 1 2 3 4 VOLTAGE (V) x.0 x.1 x.2 x.3 x.4 MARK 5 6 7 8 9 VOLTAGE (V) x.5 x.6 x.7 x.8 x.9 VOLTAGE (V) 0.x 1.x 2.x 3.x 4.x 5.x 6.x VOLTAGE (V) 0.x 1.x 2.x 3.x 5.x 6.x 7.x USP-3 （TOP VIEW ） ③Based on internal standards MARK 3 ④Represents production lot number 0 to 9, A to Z repeated (G, I, J, O, Q, W excepted) 15/16 XC61G Series 1.
