BD5223G-1TR

Overview

The BD5223G-1TR is a voltage detector IC manufactured by Rohm Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an adjustable reset delay timer and operates within a reset active voltage range of 0.8V to 6V. The typical under-voltage detection threshold is set at 2.3V with a precision of ±0.9%. The device utilizes an open-drain output type and maintains low power consumption, with circuit current specified at 0.23μA when active (at Vdet=4.8V) and 0.27μA when off. It is housed in a compact SSOP5 package and supports RoHS compliance.
