Microprocessor Supervisory Circuits with Manual Reset and Watchdog

General Description The AS1916 - AS1918 microprocessor supervisory circuits were designed to generate a reset when the monitored supply voltage falls below a factory-trimmed threshold. The reset remains asserted for a minimum timeout period after the supply voltage stabilizes. Guaranteed to be i

INTEGRATED CIRCUITS

INTEGRATED CIRCUITS FROM MOTOROLA MDTL integrated circuits provide an excellent balance of speed power dissipation, and noise immunity for general purpose digital applications. The line includes many multifunction types. Additional logic power is provided by the wired OR capability of the basic M

3 Terminal Positive Voltage Regulator 15V, 3A

Description: The NTE1918 is a positive 3–terminal voltage regulator in a TO3 type package capable of driving loads in excess of 3A. This device employs internal current limiting, thermal shutdown, and safe–area compensation. Although designed primarily as a fixed voltage regulator, the NTE19
