MN1382SEP

This product complies with the RoHS Directive (EU 2002/95/EC). Volyage Detector IC MN1382S CMOS IC for Voltage Detection  Overview  Package The MN1382S are elements that monitor the power supply voltage supplied to microcomputers and other LSI systems and issue reset signals for initializing the system after the power is first applied or for preventing runaway operation when the supply voltage fluctuates. This is a CMOS output, choose the ideal element for your application from the series' wide selection of detection ranks (16 ranks 2.0 V to 4.7 V). There is other output type, N-channel open drain output (MN13821S) and inverted CMOS output (MN13822S).  Code MINI-3DC  Pin name 1: Out Reset signal output pin 2: VSS Ground pin 3: VDD Power supply pin 3 SC  Features  Three-pin element requiring no adjustment  Wide selection of detection ranks (16 ranks 2.0 V to 4.7 V)  Highly precise detection voltage  Detection voltage with hysteresis characteristic ∆VD = 50 mV for ranks C to K ∆VD = 100 mV for ranks L to T  Low current consumption: IDD = 1 µA (typ.) for VDD = 5 V  Low fluctuation in detection voltage with tempera-ture (1 mV/°C (typ.)) 1 2 Note) Rank symbol will be marked on the package in the  area.  Applications  Battery checkers  Power outage detectors  Level discriminators  Memory backup systems  Microcomputer reset circuits  Reset circuits for other electronic circuits  Block Diagram 3 Voltage Reference 1 + Comparator − *1 Output Circuit Level Converter + Voltage Reference 2 VDD 1 OUT Comparator − 2 VSS Note) *1 : Circuits vary slightly depending on the output type (CMOS output, N-channel open drain output, or inverted CMOSoutput) Publication date: November 2007 SAG00006AED 1 This product complies with the RoHS Directive (EU 2002/95/EC).
