BD5230G-TR

Overview

The BD5230G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It features an open-drain output and operates within a supply voltage range of 0.95 V to 10 V. The device detects under-voltage conditions with a typical threshold of 3.0 V and maintains a precision of ±1%. It includes an adjustable reset delay timer and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a high-precision CMOS voltage detection circuit with adjustable delay timing capabilities.
• Provides an open-drain output interface suitable for direct connection to digital logic systems.
• Operates effectively across a wide industrial temperature range without requiring manual reset or watchdog functions.

Applications

• Monitoring microprocessor power supply rails for system stability
• Providing reset signals for embedded controller circuits
• Ensuring reliable startup sequences in portable electronic devices

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be classified as Not Recommended for New Designs. Confirm that the SSOP-5 package dimensions align with your PCB footprint requirements. Ensure the open-drain output configuration matches your downstream logic input specifications. Validate that the 3.0 V threshold meets your specific under-voltage detection needs.

Selection Notes

Select this component when a fixed 3.0 V detection threshold is required alongside customizable reset delays. Consider alternatives if lower quiescent current or higher detection accuracy is necessary. Verify compatibility with the target operating voltage range up to 10 V. Evaluate whether the open-drain output requires external pull-up resistors for proper signal levels.

Part Context

This part belongs to the BD52 series of voltage detectors from ROHM Semiconductor. It shares functional similarities with other models in the family but is distinguished by its specific 3.0 V threshold and adjustable delay characteristics. The series is known for integrating low-power CMOS technology into compact surface-mount packages.

Replacement Considerations

The BD5230G-1TR is documented as a recommended replacement with the same pinout and package. Verify electrical parameter differences, such as precision and operating voltage ranges, before substitution.
