NTE15044
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)
