NCP304, NCP305
Voltage Detector Series
The NCP304 and NCP305 series are second generation ultra鈥搇ow
current voltage detectors. These devices are specifically designed for
use as reset controllers in portable microprocessor based systems
where extended battery life is paramount.
Each series features a highly accurate under voltage detector with
hysteresis which prevents erratic system reset operation as the
comparator threshold is crossed.
The NCP304 series consists of complementary output devices that
are available with either an active high or active low reset output. The
NCP305 series has an open drain N鈥揷hannel output with an active low
reset output.
The NCP304 and NCP305 device series are available in the
SC鈥?2AB package with seven standard under voltage thresholds.
Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps
can be manufactured.
