r3115z series low voltage detector with output delay no.ea-098-061102 1 outline the r3115z series are cmos-based voltage detector ic s with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely lo w voltage and is used for system reset as an example. each of these ics consists of a voltage reference unit, a comparator, resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. the detector threshold is fixed with high accuracy internally and does not require any adjustm ent. two output types, nch open drain type and cmos type are available. since the package is wlcsp-4-p2, high density mounting on boards is possible. features ? built-in output delay circ uit............................................... typ. 100m s with an external capacitor: 0.022 f ? supply current .................................................................................... typ. 0.8 a (v dd = 3.5v) ? operating voltage range ................................................................ 0.7 to 6.0v (topt = 25 c) ? detector threshold............................................................. 0.9v to 5.0v ? accuracy detector threshold ........................................................ 2.0% ? temperature-drift coefficient of detector threshold ............ typ. 100ppm/ c ? two output types .............................................................................. nch open drain and cmos ? package ............................................................................. wlcsp-4-p2 applications ? micro controller and logic circuit reset ? battery checker ? window comparator ? wave shaping circuit ? battery back-up circuit ? power failure detector
