low voltage detector rn 5vs series outline the rn5vs series are voltage detector ics with high detector threshold accuracy and ultra-low supply current by cmos process, which can be operated at an extremely low voltage and is used, for instance, for system reset. each of these ics consists of a voltage reference unit, a comparator, resistors for voltage detection, an output driver and a hysteresis circuit. the detector threshold is fixed with high accuracy. the rn5vs series are operable by a lower voltage than that for the r 5vl series, and can be driven by a sin- gle battery. two output types, nch open drain type and cmos type, are available. since the package for these ics are sot-23-5 (mini-mold) package, high density mounting of the ics on board is possible. ?ultra-low supply current ............................ typ. 0.8?
