BD5224G-TR

Overview

The BD5224G-TR is a voltage detector IC from ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an adjustable delay timer and operates within a reset active voltage range of 0.95 V to 10 V. The typical under-voltage detection threshold is 2.4 V with a precision of ±1%. It utilizes an open-drain output type and draws a circuit current of 0.85 μA at VDET=4.8V. The device is housed in an SSOP5 package and supports a minimum packing quantity of 3000 units.

Feature Summary

• Features an adjustable delay timer for customizable reset timing.
• Provides open-drain output for flexible interface compatibility.
• Supports a wide reset active voltage range from 0.95 V to 10 V.

Applications

• Supply voltage monitoring in embedded systems
• Reset generation for microcontrollers
• Power management supervision

Procurement Notes

Verify the specific suffix requirements for your design, as the BD5224G-TR indicates taping packaging. Confirm that the component status aligns with your project lifecycle, noting it may be designated for existing customers rather than new designs. Ensure the SSOP5 package footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed threshold voltage detector with adjustable delay is required. It is suitable for applications needing a 2.4 V detection point with high precision. Consider the open-drain output capability if interfacing with various logic levels. Evaluate the power consumption characteristics against system battery life requirements.

Part Context

This part belongs to ROHM's voltage detector family, specifically the BD5224 series. It serves as a supervisory circuit for ensuring stable operation by detecting under-voltage conditions. The TR suffix denotes tape and reel packaging, facilitating automated assembly processes in manufacturing environments.

Replacement Considerations

BD5224G-1TR is listed as a recommended replacement with the same pinout and package.
