BD45415G-TR

Overview

The BD45415G-TR is a voltage detector from the ROHM BD45 series, housed in an SSOP-5 package. It features a fixed threshold voltage of 4.1 V with ±1% accuracy and a manual reset function. The device provides an open-drain output with a fixed delay time of 50 ms. It operates within a supply voltage range of 0.95 V to 10 V and supports temperatures from -40°C to +105°C. Key electrical parameters include a typical circuit current of 0.80 μA at VDET=4.8V, a power dissipation of 540 mW, and hysteresis defined as VDET x 0.05.

Feature Summary

• Includes a manual reset capability for controlled system recovery
• Provides an open-drain output interface for flexible logic integration
• Features a fixed delay timer to ensure stable voltage detection before assertion

Applications

• Processor supervisor circuits requiring fixed delay timing
• Battery-powered systems needing low quiescent current monitoring
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be limited. Ensure the SSOP-5 package dimensions match your PCB footprint requirements. Review the latest datasheet for any updates on recommended replacement parts or design-in guidelines.

Selection Notes

Select this component when a precise 4.1 V threshold with high accuracy is required. The manual reset feature distinguishes it from non-reset variants. Consider the 50 ms fixed delay against adjustable alternatives if timing precision is critical. Evaluate the low static current consumption for battery-sensitive designs compared to higher-current supervisors.

Part Context

This part belongs to the BD45 series of supervisory circuits designed for general-purpose voltage monitoring. It complements other variants in the family that offer different thresholds or reset capabilities. The SSOP-5 packaging allows for compact surface-mount implementations in space-constrained electronic assemblies.

Replacement Considerations

BD5241G-1 is listed as a same-package replacement option with similar voltage detection characteristics.
