| Microcomputer Peripheral LSIs MN1380 Series CMOS LSIs for Voltage Detection Overview The MN1380 series 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. There is a choice of three output types: CMOS output, N-channel open drain output, and inverted CMOS output. There are also three package types: M, TO-92, and a mini type for surface mounting. Choose the ideal element for your application from the series' wide selection of detection ranks (17 ranks between 2.0 and 4.9 volts), output types, and package types. Pin Assignment 23 MN1380 - R 3 2 1 M type package Features Three-pin element requiring no adjustment Wide selection of detection ranks (17 ranks between 2.0 and 4.9 volts) Highly precise detection voltage Detection voltage with hysteresis characteristic VD = 50 mV for ranks C to K VD = 100 mV for ranks L to U Low current consumption: IDD = 1A (typ.) for VDD =5V Low fluctuation in detection voltage with temperature (typ. 1 mV/C) Wide selection of output types: CMOS output, Nchannel open drain output, and inverted CMOS output Wide selection of package types: M, TO-92, and a mini type for surface mounting. 1381 23R 1 2 3 TO-92 type package 2 LCR Applications Battery checkers Power outage detectors Level discriminators Memory backup systems Microcomputer reset circuits Reset circuits for other electronic circuits Mini type package 1 3 1=OUT 2=VDD 3=VSS 1 MN1380 Series MN1380 Series Naming Conventions Microcomputer Peripheral LSIs The MN1380 series offers a wide selection of detection ranks, output types, package types, and packaging.
