BD45382G-TR

Overview

The BD45382G-TR is a voltage detector IC from the ROHM BD45 series, designed for high accuracy and low current consumption. It features a fixed reset threshold of 3.8 V with an overvoltage threshold of 3.838 V. The device provides a manual reset function and an open-drain output type. It operates within a supply voltage range up to 10 V and includes a reset delay time of 200 ms. The component has a typical static current of 800 nA and maintains an accuracy of 1%. It supports a power dissipation of 540 mW and functions across a temperature range of -40°C to +105°C.

Feature Summary

• High accuracy voltage detection with 1% threshold precision
• Low current consumption design suitable for battery-powered applications
• Manual reset capability for controlled system recovery
• Open-drain output configuration for flexible logic interfacing

Applications

• Portable electronic devices requiring precise power monitoring
• Battery-operated systems needing low quiescent current supervision
• Embedded controllers requiring manual reset functionality
• Industrial equipment operating in extended temperature environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance documentation matches specific production batches. Ensure SSOP-5 package integrity during handling. Cross-reference datasheet revisions for any parameter updates prior to integration into final designs.

Selection Notes

Select this component when a fixed 3.8 V threshold with manual reset is required. Consider the 800 nA static current for energy-sensitive designs. Verify compatibility with 10 V maximum supply voltage limits. Ensure open-drain output suits the downstream logic interface requirements without additional pull-up components.

Part Context

Part of the BD45 series voltage detectors, the BD45382G-TR offers fixed threshold options for various supply rails. It shares common family features like low current consumption and high accuracy. The G-TR suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available as the component is discontinued. Evaluate equivalent voltage detectors with similar 3.8 V thresholds, open-drain outputs, and manual reset capabilities from other manufacturers if sourcing new inventory.
