NTE15044
Integrated Circuit
CMOS, LSI for Supply Voltage Detection
Description:
The NTE15044 is an integrated circuit in a 3鈥揕ead DIP type package which generates a reset signal
for initializing microcomputers and LSI systems at their power鈥搊n time, and a reset signal for prevent-
ing an abnormal system run at power fluctuation time.
Features:
D
Generates a Reset Signal at Power鈥揙n Time Until Reaching a Constant Voltage
D
Generates a Reset Signal Below a Constant Voltage at Power鈥揙ff 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
