Overview
The NCP308SN090T1G is a supervisory circuit integrated circuit (IC) produced by onsemi. It is part of the NCP308 series, 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 triggered. This IC is optimized for low quiescent current and offers programmable delay times, making it suitable for a wide range of applications.
