BD45282G-TR

Overview

The BD45282G-TR is a single-channel voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range up to 10 V and features a threshold voltage of 2.8 V with an accuracy of ±1%. The device provides an open-drain output and supports manual reset functionality without an integrated watchdog timer. It is housed in a compact SSOP-5 package and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Provides precise monitoring of a single input voltage channel with high detection accuracy.
• Features an open-drain output configuration suitable for interfacing with various logic families.
• Includes manual reset capability for controlled system recovery operations.

Applications

• Embedded system power supply supervision
• Microcontroller reset circuit generation
• Portable electronic device voltage monitoring

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Ensure storage conditions adhere to moisture sensitivity level specifications to maintain package integrity prior to assembly.

Selection Notes

Evaluate the fixed delay timer characteristics against system startup timing requirements. Compare static current consumption metrics with battery-operated design constraints. Assess thermal performance capabilities relative to maximum power dissipation limits in enclosed environments.
