BD45295G-TR

Overview

The BD45295G-TR is a CMOS voltage detector IC from the ROHM BD45 series, designed for low current consumption and high accuracy. It features a fixed detection threshold of 2.9 V with a precision of ±1%. The device provides an open-drain output type and includes a manual reset function. It operates within a supply voltage range up to 10 V and maintains performance across a temperature range of -40°C to +105°C. The reset delay time is fixed at 50 ms, eliminating the need for external timing capacitors.

Feature Summary

• Utilizes CMOS process technology for low current consumption and high detection accuracy.
• Integrates a built-in counter timer delay circuit to provide a fixed reset delay without external components.
• Offers manual reset functionality for controlled system initialization.

Applications

• Microprocessor reset circuits
• Battery-powered equipment monitoring
• Portable devices requiring low standby current

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance and package integrity upon receipt. Check datasheet revisions for any parameter updates. Ensure storage conditions meet moisture sensitivity level requirements. Validate pinout compatibility during replacement integration.

Selection Notes

Select this component when a fixed 2.9 V threshold is required with manual reset capability. Consider the open-drain output for interfacing with various logic levels. Evaluate the 50 ms fixed delay against system startup timing requirements. Compare static current specifications against power budget constraints.

Part Context

Part of the BD45xxxG series, which offers a wide range of detection voltages in 0.1 V steps. The series utilizes CMOS processes for efficiency. This specific model is designated as Last Time Buy or Obsolete by the manufacturer.

Replacement Considerations

BD5229G-1TR is documented as a recommended replacement with the same SSOP-5 package and similar 2.9 V detection voltage, though it features adjustable delay instead of fixed delay.
