BD52W06G-CTR

Overview

The BD52W06G-CTR is a dual-output window voltage detector IC from Rohm Semiconductor, designed for automotive applications. It features adjustable reset delay timers set by external capacitors and operates within a -40°C to +125°C temperature range. The device utilizes N-ch open-drain outputs and supports over-voltage detection at 5.5V typical and under-voltage detection at 4.5V typical. It offers ±5% precision for the VDET parameter and includes hysteresis voltage defined as VDET multiplied by 0.01. The circuit current in the OFF state is 0.3µA when VDET is set to 4.50V and 5.50V.

Feature Summary

• Dual output configuration with flexible time delay settings via external capacitors
• Automotive-grade qualification supporting functional safety analysis
• High-precision low-power CMOS process with wide operating temperature range

Applications

• Automotive system power supply monitoring
• Window voltage detection for critical circuits
• Reset signal generation with adjustable timing delays

Procurement Notes

Verify the specific orderable part number against the manufacturer's latest documentation to ensure compatibility with required packaging options such as tape and reel quantities. Confirm that the AEC-Q100 Grade 1 qualification meets the target application's environmental standards. Check for any recent lifecycle status updates or recommended replacement parts if the component is nearing end-of-life.

Selection Notes

Select this component when dual-channel voltage supervision with customizable delay characteristics is required for automotive environments. The adjustable delay feature allows designers to tailor response times using external capacitors rather than fixed internal values. Ensure the input voltage range aligns with the 5.5V over-voltage and 4.5V under-voltage thresholds specified for reliable operation across the full industrial temperature spectrum.

Part Context

This device belongs to Rohm's Nano Energy series of window voltage detectors specifically engineered for automotive use. It integrates high-accuracy detection circuits with low standby current consumption, making it suitable for battery-powered or energy-sensitive vehicle subsystems. The SSOP6 package provides a compact footprint for space-constrained printed circuit board layouts.
