Overview
The NCV308SN330T1G is a part of the NCP308 series of supervisory circuits from onsemi. This IC is designed to monitor system voltages and assert a RESET signal when the voltage drops below a specified threshold or when the Manual Reset (MR) input is driven low. The device is optimized for a wide supply voltage range from 1.6 V to 5.5 V and features a very low quiescent current of 1.6 µA. It is available in both fixed and externally adjustable versions, making it versatile for various applications.
