NCP308 Datasheet, PDF (1/11 Pages) ON Semiconductor – Low Quiescent Current, Programmable Delay Time Supervisory Circuit

NCP308, NCV308
Low Quiescent Current,
Programmable Delay Time,
Supervisory Circuit
The NCP308 series is one of the ON Semiconductor Supervisory
circuit IC families. It is optimized to monitor system voltages from
0.405 V to 5.5 V, asserting an active low open−drain RESET output,
together with Manual Reset (MR) Input. The part comes with both
fixed and externally adjustable versions.
