All of unit are tested and specified under load conditions such that Topt=25°C except for Detector Threshold

Temperature Coefficient, Detector Output Delay Time and Release Output Delay Time.

*1: Consumption current through SENSE pin is not included.

*2: In case that the VDD pin and SENSE pin are connected and the value shows the minimum supply voltage (VDD) when the

output voltage at detector threshold can be maintained as 0.1V or less. (In case of Nch open drain type, pull-up resistor

is 470kΩ and pull-up voltage is set at 5V for testing.) If VDD is high enough, down to 0V is acceptable for SENSE pin.

*3: In case of CMOS type

*4: In case of Nch Open Drain type

*5: In the case of CMOS output type: Time interval from forcing pulsive 6.0V to -VDET-2.0V or 0V, or from forcing 0V to

-VDET+2.0V or 6.0V to SENSE pin, to when the output voltage will reach VDD/2.

In the case of Nch Open drain output type: Output pin is pulled up to 5V with 470kΩ and time interval from forcing 6.0V

to -VDET-2.0V or 0V, or forcing pulsive 0V to -VDET+2.0V or 6.0V to when the output voltage reaches up to 2.5V.

RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)

All of electronic equipment should be designed that the mounted semiconductor devices operate within the

recommended operating conditions. The semiconductor devices cannot operate normally over the

recommended operating conditions, even if when they are used over such conditions by momentary

electronic noise or surge. And the semiconductor devices may receive serious damage when they continue

to operate over the recommended operating conditions.
