NCP303LSN45T1G
NCP302, NCP303 Voltage Detector Series with Programmable Delay The NCP302 and NCP303 series are second generation ultra−low current voltage detectors that contain a programmable time delay generator. 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 and an externally programmable time delay generator. This combination of features prevents erratic system reset operation. The NCP302 series consists of complementary output devices that are available with either an active high or active low reset. The NCP303 series has an open drain N−Channel output with an active low reset output. http://onsemi.com MARKING DIAGRAM 5 1 xxx A Y W G • • = Specific Device Code = Assembly Location = Year = Work Week = Pb−Free Package 5 Features • • • • • • • TSOP−5/ SOT23−5 CASE 483 Quiescent Current of 0.5 mA Typical High Accuracy Undervoltage Threshold of 2.0% Externally Programmable Time Delay Generator Wide Operating Voltage Range of 0.8 V to 10 V Complementary or Open Drain Output Active Low or Active High Reset Specified Over the −40°C to +125°C Temperature Range (Except for Voltage Options from 0.9 to 1.1 V) NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free and are RoHS Compliant PIN CONNECTIONS Reset Output 1 Input 2 Ground 3 ORDERING INFORMATION NCP303LSNxxT1 Open Drain Output Configuration Input 2 RD GND 5 Input 1 Reset Output RD 1 * 3 4 N.C.
