BD45412G-TR

Overview

The BD45412G-TR is a single-channel voltage detector from the ROHM BD45 series, housed in an SSOP-5 package. It features a typical under-voltage detection threshold of 4.1 V with ±1% precision. The device supports a maximum supply voltage of 10 V and includes manual reset functionality. It operates within a temperature range of -40°C to +105°C. Key electrical characteristics include a fixed reset delay timer of 200 ms, open-drain output, and low circuit current consumption of approximately 0.80 µA at active states.

Feature Summary

• Provides precise monitoring of a single power supply rail with high accuracy.
• Includes manual reset capability for controlled system recovery.
• Features open-drain output compatible with various logic levels.
• Operates reliably across extended industrial temperature ranges.

Applications

• Microprocessor reset circuits
• Battery-powered device supervision
• Industrial control system monitoring

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing batches. Ensure storage conditions adhere to moisture sensitivity levels for SSOP packages. Validate pinout compatibility during integration planning. Review datasheet revisions for any parameter updates prior to final design approval.

Selection Notes

Select this component when a fixed 4.1 V threshold with manual reset is required. Compare against BD5241G-1 for similar package options but different delay characteristics. Consider static current requirements if battery life is critical. Verify that the open-drain output suits the downstream logic interface. Check availability constraints given the product lifecycle stage.

Part Context

Part of the BD45 supervisory circuit family designed for general-purpose voltage monitoring. Shares common packaging and basic operational principles with other BD45 variants. Differentiated by its specific 4.1 V threshold setting and manual reset feature. Designed for surface-mount assembly in compact electronic designs.

Replacement Considerations

BD5241G-1 is listed as a recommended replacement with the same SSOP-5 package. Note differences in reset delay (adjustable vs. fixed) and manual reset support. Verify electrical parameter compatibility before substitution.
