This product complies with the RoHS Directive (EU 2002/95/EC). Volyage Detector IC MN13822S CMOS IC for Voltage Detection Overview Package The MN13822S are elements that monitor the power supply voltage Code supplied to microcomputers and other LSI systems and issue reset signals for MINI-3DC initializing the system after the power is rst applied or for preventing runaway Pin name operation when the supply voltage uctuates. 1: Out Reset signal output pin This is a inverted CMOS output, choose the ideal element for your 2: V Ground pin SS application from 5 detection ranks. 3: V Power supply pin DD There is other output types, CMOS output (MN1382S) and N-channel open 3 drain output (MN13821S). SE Features Three-pin element requiring no adjustment 1 2 Highly precise detection voltage Note) Rank symbol will be marked on the Detection voltage with hysteresis characteristic package in the area. VD = 50 mV for ranks C VD = 100 mV for ranks L Low current consumption: I = 1 A (typ.) for V = 5 V DD DD Low uctuation in detection voltage with tempera-ture (1 mV/C (typ.)) Applications Battery checkers Power outage detectors Level discriminators Memory backup systems Microcomputer reset circuits Reset circuits for other electronic circuits Block Diagram 3 V DD Voltage + Reference 1 Comparator 1 * 1 Level Converter OUT Output Circuit + Comparator Voltage Reference 2 2 V SS Note) *1 : Circuits vary slightly depending on the output type (CMOS output, N-channel open drain output, or inverted CMOSoutput) Publication date: December 2008 SAG00008AED 1 Maintenance/ Discontinued Maintenance/Discontinued includes following four Product lifecycle stage.
