■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, the VIN voltage drops while the IC is operating and a

malfunction may occur as a result of the IC’s through current.

3. In order to stabilize the IC’s operations, please ensure that the VIN pin’s input frequency’s rise and fall times are more than

μ s/V.

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

please strength the line between VIN and the GND pin and connect about 0.22

μF of a capacitor between the VIN pin and

the GND pin.

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

and fall times. Referring to the figure below, the ignoring time (no reaction time) lasts for 900

μs at maximum.

6. The EN pin of the XC6121 series is not internally pulled up. When using the watchdog function, please drive the EN pin in

high level. The EN pin of the XC6122 series is internally pulled up. The watchdog function can be used even the EN pin

left open. The ENB pin of the XC6123 series is not internally pulled down. When using the watchdog function, please

drive the ENB pin in low level. The ENB pin of the XC6124 series is internally pulled up. The watchdog function can be

used even the ENB pin left open.
