BD5223FVE-TR

Overview

The BD5223FVE-TR is a voltage detector with an adjustable delay time, manufactured by ROHM Semiconductor. It features an open-drain output and operates within a reset active voltage range of 0.95V to 10V. The typical under-voltage detection voltage is 2.3V with a precision of ±1%. The circuit current is 0.85μA when ON (at VDET=4.8V) and 0.85μA when OFF. It supports manual reset functionality and includes a watchdog timer. The device is housed in a VSOF5 package and is available in taping packaging with a unit quantity of 3000.
