BD45352G-TR

Overview

The BD45352G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a fixed detection threshold voltage of 3.5 V with an accuracy of ±1%. The device operates within a power supply voltage range up to 10 V and includes a manual reset function. It utilizes an open-drain output type and provides a fixed reset delay time of 200 ms. The component supports surface mount installation in an SSOP-5 package and functions across a temperature range from -40°C to +105°C.

Feature Summary

• Fixed detection threshold voltage of 3.5 V with high precision
• Manual reset capability for system control flexibility
• Open-drain output configuration for interface compatibility
• Low static current consumption for energy efficiency

Applications

• Microprocessor reset circuits
• Power supply monitoring systems
• Embedded system supervision

Procurement Notes

Verify the obsolete status and last-time-buy availability through official ROHM channels or authorized distributors before finalizing procurement plans. Confirm that the SSOP-5 package and reel/cut-tape packaging options meet production requirements. Ensure compliance with RoHS directives as specified in the datasheet. Cross-reference the specific ordering suffix to confirm the exact packing type required for assembly processes.

Selection Notes

Select this component when a precise 3.5 V threshold is required for single-input voltage monitoring. The fixed 200 ms delay ensures stable reset generation during power-up sequences. Consider the low standby current for battery-operated or power-sensitive designs. Verify that the open-drain output aligns with the logic levels of the connected microcontroller or processor inputs.

Part Context

This part belongs to the BD45 series of supervisory circuits from ROHM Semiconductor. It is specifically engineered for voltage detection tasks requiring manual reset functionality. The series offers various threshold voltages and packages, but this model focuses on the 3.5 V specification. It serves as a critical component for ensuring reliable system startup and operation monitoring in electronic devices.

Replacement Considerations

The BD5235G-1 is listed as a similar level replacement with the same SSOP-5 package. However, note that the BD5235G-1 features an adjustable delay timer, whereas the BD45352G-TR has a fixed 200 ms delay. Verify functional compatibility regarding the reset delay characteristics before substitution.
