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.

the IC is operating and malfunction may occur as a result of the IC’s output current. Please be careful with using the

XC6111~XC6117 series (without hysteresis).

4. Noise at the power supply may cause a malfunction of the watchdog operation or the circuit. In such case, please

pin.

5. Protecting against a malfunction while the watchdog time out period, an ignoring time (no reaction time) occurs to the rise

6. The watchdog function can be disabled by connecting a three-state device to the WDI pin as a result of the high impedance

state of the WDI pin. This is effective when the watchdog function is not required, for example, during data loading to the

showed in the block diagrams of page 4 and 5. The WDI input is designed for minimizing the input current by placing the

three-state device multiplied by the resistance value of the series resistor (RWD) when the three-state device is in the state

of high impedance. The voltage level must be reaching the threshold level of the WD so that a three-state device with small

leakage current should be selected.

The other series is available in the name of XC6121~XC6124 with the ON/OFF control pin for the watchdog function.

When these series is used, external parts such as the three-state device is not required.
