CMOS power supply support circuit featuring a fixed +4.4V threshold voltage with 1% accuracy. This voltage detector provides a single channel of power-on reset functionality, outputting a TOTEM-POLE signal. Operating across a wide temperature range of -40°C to 125°C, it offers low quiescent current of 550nA and a maximum supply voltage of 7V. Packaged in an SSOP-5 surface mount configuration, it is supplied on tape and reel.
