This IC, developed using CMOS technology, is a high-accuracy voltage detector. The detection voltage and release voltage are fixed internally with an accuracy of ±1.5%.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even if the SENSE pin voltage (VSENSE) falls to 0 V. The SENSE pin also has a built-in reverse connection protection circuit that reduces current in the SENSE pin during a reverse connection.
The release signal can be delayed by setting a capacitor externally, and the release delay time accuracy is ±15% (CD = 3.3 nF). The output form is Nch open-drain output.
