The NCP308 series is one of the ON Semiconductor Supervisory circuit familiies. It is optimized to monitor system voltages from 0.405 V up to 5.5 V., asserting an active low open-drain /RESET output, together with Manual Reset (/MR) Input. The part comes with both fixed and internally adjustable versions

• Very low Quiescent Current 1.6 µV
• Fixed threshold voltage version for Standard Voltage Rails
• Adjustable threshold version available with low threshold (0.405 V min.)
• High Threshold Voltage Accuracy: 0.31% typical
• Wide Supply voltage range 1.6 to 5.5 V
• Manual Reset Input (/MR) - Open Drain /RESET Output (Push Pull available upo request)
• Flexible Delay Time Programmability (1.25 ms up to 10 s)
