Overview
The NCP308MTADJTBG is a part of the NCP308 series of supervisory circuit ICs produced by onsemi. This device 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 NCP308MTADJTBG is particularly versatile, offering adjustable threshold voltage and programmable reset delay times, making it suitable for a wide range of applications.
