11 / 20 page 11/20 XC6118 Series A typical circuit example is shown in Figure 1, and the timing chart of Figure 1 is shown in Figure 2. 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 XC6118N 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 [t DF] is defined as time which ranges from VSEN=VDF to the VOUT of “Low” level (especially, when the Cd pin is not connected: t DF0). 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). ■OPERATIONAL EXPLANATION Figure 1: Typical application circuit example Figure 2: The timing chart of Figure 1 *The XC6118N series (N-ch open drain output) requires a pull-up resistor for pulling up output.
