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 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.

Notes 1: Output cannot be specified for power supply voltages under 1.5 V because operation is not guaranteed for that range. 2: VDL: Detection voltage for drop in power supply voltage VDH: Detection voltage for rise in power supply voltage tOL : Time lag between the time that the power supply voltage reaches the detection voltage (VDL or VDH) and the time that the output pin (OUT) goes to "L" level. tOH : Time lag between the time that the power supply voltage reaches the detection voltage (VDL or VDH) 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 VDD pins.
