BD4928FVE-TR

Overview

The BD4928FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features a typical under-voltage detection threshold of 2.8V with a precision of ±1%. The device supports a reset active voltage range from 0.95V to 10V and utilizes a CMOS output type with a low-active reset state. Operating current is specified at 0.60μA (ON) and 0.85μA (OFF) at Vs=4.8V. It operates within a temperature range of -40°C to 105°C and is housed in a VSOF-5 package.

Feature Summary

• CMOS voltage detection circuit with high accuracy
• Low power consumption design suitable for battery applications
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring voltage supervision
