BD53E45G-TR

Overview

The BD53E45G-TR is a voltage detector IC from ROHM Semiconductor, featuring a 4.5 V threshold and CMOS output in an SSOP-5 package. It supports a reset active voltage range of 0.95 V to 10 V with ±1% precision. The device includes an adjustable delay timer and operates within -40°C to +105°C. Power dissipation is rated at 540 mW. This component is classified as Not Recommended for New Designs (NRND).

Feature Summary

• CMOS output type for direct logic interfacing.
• Adjustable reset delay timer functionality.
• High detection accuracy with ±1% precision.
• Wide operating supply voltage range.

Applications

• Microprocessor reset circuits.
• Battery-powered system monitoring.
• Portable electronic device power management.

Procurement Notes

Verify the current lifecycle status before procurement, as this part is designated as Not Recommended for New Designs. Confirm availability through authorized distributors, noting that stock levels may be limited due to end-of-life planning. Ensure the SSOP-5 package and reel packaging meet your assembly requirements. Cross-reference with replacement candidates if long-term supply stability is required for production.

Selection Notes

Select this component when a CMOS output is preferred over open-drain configurations for voltage supervision. The adjustable delay feature allows customization for specific startup timing needs. Consider the wide input voltage range up to 10 V for flexible power rail monitoring. Evaluate the NRND status against product longevity requirements and potential obsolescence risks in the supply chain.

Part Context

This voltage detector belongs to the BD52(53)ExxG series, designed for precise power management supervision. It utilizes CMOS technology to achieve low current consumption and high accuracy. The series supports various detection voltages and output types, catering to diverse embedded system requirements while maintaining compact footprint compatibility.

Replacement Considerations

BD5245G-1TR is a recommended replacement with the same pinout and package. It offers similar detection voltage but features an open-drain output instead of CMOS. Verify interface compatibility when substituting, as the output stage difference may require circuit adjustments.
