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 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

2.0 and 4.9 volts), output types, and package types.

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 = 1µA (typ.) for VDD

= 5 V

Low fluctuation in detection voltage with tempera-

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.
