MN1381

The MN1381 is a type of CMOS LSIs for voltage detection.MN1381 monitors the power supply voltage supplied to microcom puter and other LSI systems and issue reset signals for initializing the system after the power is first used or for pre venting runway operation while the supply voltage fluctuates.

Features of MN1381 are: (1)three pin element requiring no adjustment; (2)wide selection of detection ranks(17 rank s between 2.0 and 4.9 volts); (3)highly precise detection voltage;(4)low fluctuation in detection voltage with temper ature(typ.1mV/); (5)wide selection of output types:CMOS output, N-channel open drain output, and inverted CMOS output; (6)wide selection of package types:M, TO-92, and a mini type for surface mounting.

The absolute maximum ratings and electrical characteristics of the MN1381 can be summarized as: (1)power supply voltage: 7.0V; (2)output voltage: -0.3to VDD+0.3V; (3)operating ambient temperature:-20 to 70; (4)storage te mperature: -55 to 125. Electrical characteristics: (1)power supply current(VDD=5V, loard resistance=10kW): 1uA typ and 5uA max; (2)detection voltage for drop in power supply voltage(Ta=25)-2V min and +2V max; (3)"H" level output voltage(CMOS output, IOH=40uA): 0.8VDD min and VDD V max; (4)"H" level output voltage(N-channel open drain output, VDD=1.8V, IOL=0.7mA):Vss min and 0.4V max, etc.
