BD5228G-2MTR

Overview

The BD5228G-2MTR is a single-channel voltage detector IC from ROHM Semiconductor, designed for automotive applications. It features a fixed threshold voltage of 2.8V with an accuracy of ±2.5%. The device operates within a supply voltage range of 0.8V to 7V and draws a typical operating current of 270nA. It provides an open-drain output with a reset delay time of 55.5ms. The component is qualified under AEC-Q100 standards and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification
• Ultra-low power consumption suitable for battery monitoring
• Adjustable reset delay via external capacitor connection

Applications

• Automotive engine control unit supervision
• Battery voltage monitoring in electric vehicles
• Microprocessor reset circuits in harsh environments

Procurement Notes

Verify the specific suffix '2M' indicates the adjustable delay variant rather than fixed timing. Confirm package integrity upon receipt as SSOP-5 is sensitive to moisture. Ensure design compatibility with AEC-Q100 Grade 1 requirements for automotive deployment. Cross-reference datasheet revisions to confirm pinout consistency with previous production runs.

Selection Notes

Select this model when a precise 2.8V detection threshold is required for system supervision. Choose the adjustable delay feature if noise immunity or startup sequencing requires customizable timing. Consider the low quiescent current for energy-efficient designs. Verify that the open-drain output interface matches the downstream logic level requirements.

Part Context

This component belongs to the BD52xxG-M series of Nano Energy voltage detectors. It is part of ROHM's portfolio of CMOS reset ICs optimized for automotive use. The series offers various threshold voltages in 0.1V steps, allowing designers to tailor detection levels precisely. The BD5228G-2MTR specifically targets applications requiring robust supervision at the 2.8V level.

Replacement Considerations

BD5228G-2M is the base part number without reel packaging specification.
