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.
