BD53E30G-TR

Overview

The BD53E30G-TR is a voltage detector supervisory circuit manufactured by ROHM Semiconductor. It features a detection threshold of 3.0 V with an accuracy of ±1%. The device operates within a supply voltage range of -300 mV to 10 V and supports a maximum power dissipation of 540 mW. It utilizes a CMOS output type and includes a programmable reset delay timer. The component is housed in an SSOP-5 package and functions without manual reset, watchdog timer, or battery backup switch capabilities.

Feature Summary

• Features a programmable reset delay timer for customizable timing control
• Provides high detection accuracy of ±1% at the 3.0 V threshold
• Utilizes CMOS output structure for direct logic interface compatibility

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• CMOS-based system power management applications
• Adjustable delay voltage detection in embedded systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to the Not Recommended for New Designs (NRND) status. Confirm RoHS compliance documentation matches current regulatory requirements. Ensure ordering suffixes align with specific packaging needs. Validate that existing inventory meets long-term maintenance requirements as new design adoption is discouraged.

Selection Notes

Select this component only for legacy system maintenance or replacement scenarios given its NRND classification. Evaluate the BD5230G-1 as a recommended alternative if new designs are required. Consider the adjustable delay feature necessity versus fixed-delay alternatives. Verify that the SSOP-5 footprint and CMOS output characteristics match the target PCB layout constraints.

Part Context

This part belongs to the BD52(53)ExxG series of supervisory circuits from ROHM Semiconductor. It is specifically categorized under PMIC - Power Management ICs. The device serves as a voltage detector designed for monitoring single-input power rails in electronic systems requiring reliable reset signal generation based on voltage thresholds.

Replacement Considerations

The BD5230G-1TR is identified as a recommended replacement with the same pinout and package. Both components share similar detection voltages and adjustable delay features, though output types differ between CMOS and open drain configurations.
