The NCP303 is an ultra−low current voltage detector that contains 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.
It features a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator.
This combination of features prevents erratic system reset operation.

Features:

• Quiescent Current of 0.5 uA 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
