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

MN1380 Series Naming Conventions
The MN1380 series offers a wide selection of detection ranks, output types, package types, and packaging. All
combinations use the following naming conventions. When ordering, be sure to give the correct part number using
these naming conventions.
Winding direction for tape packaging
(TA) ...... Tape packaging for TO-92 type package
(TX) ...... Embossed tape packing for mini type package
(TW) ..... Embossed tape packing for mini type package
For further details, see the package specifications.

Description of Operation
Notes
1: Output cannot be specified for power supply voltages under 1.5 V because operation is not guaranteed for that range.
2: V
DL
: Detection voltage for drop in power supply voltage
V
DH
: Detection voltage for rise in power supply voltage
t
OL
: Time lag between the time that the power supply voltage reaches the detection voltage (V
DL
or V
DH
) and the time that the
output pin (OUT) goes to "L" level.
t
OH
: Time lag between the time that the power supply voltage reaches the detection voltage (V
DL
or V
DH
) and the time that
the output pin (OUT) goes to "H" level.
3: These characteristics for the N-channel open drain output are when a load resistor is connected between the OUT and V
DD
pins.
