Integrated Circuit

CMOS, LSI for Supply Voltage Detection

Description:

The NTE15044 is an integrated circuit in a 3–Lead DIP type package which generates a reset signal

for initializing microcomputers and LSI systems at their power–on time, and a reset signal for prevent-

ing an abnormal system run at power fluctuation time.

Features:

D Generates a Reset Signal at Power–On Time Until Reaching a Constant Voltage

D Generates a Reset Signal Below a Constant Voltage at Power–Off Time

D Generates a Reset Signal when the Supply Voltage Falls, and Cancels it when the Supply

Voltage is Restored

D Capable of Detecting a Battery Service Life

D 3–Pin Adjustment–Free Device

D High–Accuracy Voltage Detection

D Low Power Consumption: 10µA Typ @ V_DD= 5V

Absolute Maximum Ratings: (V_SS= 0, T_A= +25°C unless otherwise specified)
