DATA SHEET www.onsemi.com Voltage Detector Series MARKING DIAGRAM with Programmable Delay 5 NCP302, NCP303 TSOP5/ xxx AYW 5 SOT235 The NCP302 and NCP303 series are second generation ultralow 1 CASE 483 1 current voltage detectors that contain a programmable time delay generator. These devices are specifically designed for use as reset xxx = Specific Device Code controllers in portable microprocessor based systems where extended A = Assembly Location battery life is paramount. Y = Year Each series features a highly accurate undervoltage detector with W = Work Week hysteresis and an externally programmable time delay generator. This = PbFree Package combination of features prevents erratic system reset operation. (Note: Microdot may be in either location) 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 NChannel output with an active low PIN CONNECTIONS reset output. Reset Features 1 5 C D Output Quiescent Current of 0.5 A Typical 2 Input High Accuracy Undervoltage Threshold of 2.0% Externally Programmable Time Delay Generator 3 4 N.C. Ground Wide Operating Voltage Range of 0.8 V to 10 V (Top View) Complementary or Open Drain Output Active Low or Active High Reset Specified Over the 40C to +125C Temperature Range ORDERING INFORMATION (Except for Voltage Options from 0.9 to 1.1 V) See detailed ordering and shipping information in the ordering information section on page 22 of this data sheet.
