BD52W03G-CTR

Overview

The BD52W03G-CTR is a Nano Energy™ dual-output window voltage detector IC from Rohm Semiconductor, designed for automotive applications. It features adjustable reset delay times set via an external capacitor and operates within a supply voltage range of 1.6V to 6V. The device provides under-voltage detection at 1.62V and over-voltage detection at 1.98V with ±5% precision. It utilizes an N-channel open-drain output configuration and maintains low circuit current consumption of 0.3µA in the OFF state. Qualified to AEC-Q100 Grade 1 standards, it supports functional safety analysis and operates reliably across temperatures from -40°C to +125°C.

Feature Summary

• Dual-output window voltage monitoring capability with independent under-voltage and over-voltage detection thresholds.
• Adjustable reset delay timer functionality allowing time delay settings through external capacitor connection.
• Automotive-grade reliability with AEC-Q100 qualification and functional safety support capabilities.
• Ultra-low power consumption design suitable for battery-operated systems with minimal standby current draw.

Applications

• Automotive electronic control unit (ECU) power supply supervision
• Battery management system voltage monitoring
• Industrial equipment reset circuit generation
• Consumer electronics power failure detection

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches SSOP-6 requirements for your PCB layout. Ensure ordering suffix aligns with tape-and-reel packaging needs. Validate temperature grade compliance for your specific operating environment before finalizing procurement decisions.

Selection Notes

Select this component when dual-window voltage monitoring with programmable delay timing is required. Consider its automotive qualification if deploying in vehicle environments. Evaluate the 1.6V to 6V operating range against your system's supply voltage constraints. Assess the need for adjustable delay functionality versus fixed-delay alternatives in your circuit design.

Part Context

This part belongs to Rohm's Nano Energy™ series of voltage detectors featuring adjustable delay timers. The BD52W03G variant specifically offers dual-output window detection capabilities. It complements other single-output detectors in the family while providing enhanced monitoring flexibility for complex power sequencing requirements in modern electronic systems.

Replacement Considerations

BD52W03G-C serves as the non-tape reel equivalent with identical electrical characteristics. Verify pin compatibility and package dimensions when substituting between these variants. Both parts share the same functional specifications and automotive qualifications for seamless integration into existing designs.
