BD45365G-TR

Overview

The BD45365G-TR is a voltage detector from the BD45 series by ROHM Semiconductor, housed in an SSOP-5 surface-mount package. It features a fixed threshold voltage of 3.6 V with a precision of ±1%. The device provides an open-drain output and includes manual reset functionality without a watchdog timer. It operates within a supply voltage range up to 10 V and maintains a low static current of 800 nA. The reset delay time is fixed at 50 ms, and it functions across a temperature range of -40°C to +105°C.

Feature Summary

• Provides precise under-voltage detection with a fixed 3.6 V threshold and ±1% accuracy.
• Features an open-drain output compatible with various logic families for system reset signaling.
• Includes manual reset capability to allow external control over the reset state.

Applications

• Processor supervisor circuits requiring stable voltage monitoring
• Battery-powered devices needing low quiescent current supervision
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing batches. Ensure SSOP-5 footprint compatibility during integration. Check for obsolescence notices or last-time buy deadlines from the manufacturer. Validate datasheet revisions against design requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.6 V threshold is required for system supervision. Consider the open-drain output configuration for interface flexibility. Evaluate the 800 nA static current for power-sensitive applications. Verify that the 50 ms reset delay meets timing constraints. Ensure the SSOP-5 package fits the available board space.

Part Context

This part belongs to the BD45 series of voltage detectors, designed for supervisory applications. It shares the SSOP-5 package and general architecture with other variants in the family, differing primarily in threshold voltage settings. The series targets cost-effective and compact monitoring solutions for consumer and industrial electronics.

Replacement Considerations

BD45365G is listed as a similar level replacement with the same package. Verify electrical parameter equivalence, particularly the 3.6 V threshold and open-drain output characteristics, before substitution.
