NCP300, NCP301
Voltage Detector Series
The NCP300 and NCP301 series are second generation ultra−low
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 undervoltage detector with
hysteresis which prevents erratic system reset operation as the
comparator threshold is crossed.
The NCP300 series consists of complementary output devices that
are available with either an active high or active low reset output. The
NCP301 series has an open drain N−Channel output with either an
active high or active low reset output.
The NCP300 and NCP301 device series are available in the
Thin TSOP−5 package with standard undervoltage thresholds.
Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps
can be manufactured.
Features Quiescent Current of 0.5 �A Typical High Accuracy Undervoltage Threshold of 2.0% Wide Operating Voltage Range of 0.8 V to 10 V Complementary or Open Drain Reset Output Active Low or Active High Reset Output Pb−Free Packages are Available
Typical Applications Microprocessor Reset Controller Low Battery Detection Power Fail Indicator Battery Backup Detection
This device contains 25 active transistors.
