BU4224FVE-TR

Overview

The BU4224FVE-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an adjustable delay timer and operates within a reset active voltage range of 0.7 V to 7 V. The typical under-voltage detection threshold is 2.4 V with a precision of ±1%. The device utilizes an open-drain output type and maintains low power consumption, with circuit current specified at 0.40 μA (on) and 0.55 μA (off) when Vdet=4.8V. It is housed in a VSOF-5 package.

Feature Summary

• Adjustable reset delay timer functionality
• Open-drain output configuration
• Low power consumption design

Applications

• Voltage monitoring in portable devices
