Application Information

1. Explanation of Operation

The detection and release voltages are used as threshold voltages. When the voltage applied to VDD pin reaches

the appropriate threshold voltage, OUT pin voltage switches from either “High” to “Low” or from “Low” to “High”.

Please refer to the Timing Waveform and Electrical Characteristics for information on hysteresis.

Because the BD71L4L-1 uses an open drain output type, it is necessary to connect a pull-up resistor to VDD or

other power supply].
