BD5230G-2MTR

Overview

The BD5230G-2MTR is a Nano Energy CMOS reset IC manufactured by ROHM Semiconductor, designed for automotive applications. It features an adjustable delay timer and operates within a supply voltage range of 0.8 V to 6 V. The device detects under-voltage conditions with a typical threshold of 3.0 V and offers high precision accuracy of ±2.5%. It consumes low circuit current, specified at 0.23 µA in the active state and 0.27 µA in the off state. The output type is open drain, and it lacks manual reset or watchdog functions. The component is housed in an SSOP-5 package and supports functional safety analysis.

Feature Summary

• Integrated adjustable delay timer allowing customization via external capacitor
• High detection voltage precision of ±2.5% across the operating temperature range
• Ultra-low power consumption suitable for battery-operated systems
• Automotive qualification supporting functional safety analysis

Applications

• Automotive electronic system monitoring
• Microprocessor reset circuits
• Battery-powered device supervision
• General-purpose voltage monitoring in industrial equipment

Procurement Notes

Verify the specific suffix '2M' indicates the automotive-grade variant with adjustable delay capabilities. Confirm the SSOP-5 package dimensions match your PCB footprint requirements. Ensure the open-drain output configuration aligns with your target logic level and pull-up resistor design. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a precise 3.0 V detection threshold is required for automotive or industrial environments. Choose the adjustable delay feature if timing control for reset signals is necessary compared to fixed-delay alternatives. Consider the low standby current for energy-sensitive designs. Verify that the open-drain output suits your interface needs without requiring additional level shifting.

Part Context

This part belongs to the BD52xx series of Nano Energy CMOS reset ICs from ROHM Semiconductor. The series is characterized by high precision and low current consumption. The BD5230G-2MTR specifically targets the 3.0 V detection point within the broader lineup that spans various voltage thresholds. It represents an evolution in automotive-grade supervision components offering configurable timing.

Replacement Considerations

The BD49E30G is listed as a similar level replacement with the same package but different electrical characteristics such as higher current consumption and no adjustable delay. The BD5230G-1TR is another alternative within the family, though it may lack specific automotive qualifications found in the -2M variant.
