BU4830FVE-TR

Supervisors Overview

The BU4830FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single power supply lines. It features an open-drain output and operates within a reset active voltage range of 0.7 V to 7 V. The typical under-voltage detection threshold is set at 3.0 V with a precision of ±1%. The device functions reliably across a temperature range of -40°C to +125°C, drawing a circuit current of 0.40 μA in the ON state and 0.55 μA in the OFF state at VDET=4.8V. It utilizes a VSOF-5 package.
