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.
Features

ture (typ. 1 mV/˚C)
Wide selection of output types: CMOS output, N-
channel open drain output, and inverted CMOS
output
Wide selection of package types: M, TO-92, and a
mini type for surface mounting.
