Microcomputer Peripheral LSIs MN1380 Series CMOS LSIs for Voltage Detection Overview Pin Assignment 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 23 operation when the supply voltage fluctuates. MN1380 - R There is a choice of three output types: CMOS output, N-channel open drain output, and inverted CMOS out- put. 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 21 3 2.0 and 4.9 volts), output types, and package types.
