This IC, developed using
CMOS technology, is a high-accuracy
voltage detector with the supply
voltage divided output. 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. The supply
voltage divided output is prepared in this IC. The supply
voltage divided output is a function that divides the VSENSE into VSENSE/6, VSENSE/8, VSENSE/12 or VSENSE/14 and outputs the
voltage. For example, this function makes it possible that the IC connects to a low
voltage microcontroller A/D converter directly and the microcontroller monitors a battery
voltage.
