R3134K (DFN(PLP)1212-6) and R3134Q (SC-88A) are the discontinued products as of March, 2016. R3134x SERIES LOW VOLTAGE DETECTOR WITH BUILT-IN DELAY CIRCUIT NO.EA-209-160316 OUTLINE R3134x Series are CMO-Sbased voltage detector ICs with bui-in lt delay circuit, high detector threshold accuracy, and ultra low supply current, which can operate at low voltage. These ICs can be used as system reset generators, and each of these ICs consists of a voltage reference, a comparator, resistors for setting voltage detector threshold, an output driver transistor, manual reset circuit, and an output delay generator. Detector threshold is fixed internally with high accuracy and requires no adjustment. When a supply voltage crosses a setting detector threshold voltage from a high value to a lower value, this IC generates reset signal. R3134x Series output at its detect. Since each of R3134x Series embeds an output delay generator, during a setting 240ms delay time, which is fixed in the IC, this IC keeps the reset condition after they are released. Released conditions will be kept for the delay time from when a supply voltage crosses a setting detector threshold voltage from a low value to a higher value, or from when the manual reset signal is released. Two output types, Nch open drain type and CMOS type, are available. Since the packages for these ICs are DFN(PLP)1212-6, SOT-23-5, and SC-88A, high density mounting of the ICs on board is possible.
