BD5224G-2MTR

Overview

The BD5224G-2MTR is a Nano Energy™ adjustable delay voltage detector IC designed for automotive applications. It features a typical threshold voltage of 2.4 V with ±2.5% precision and an output active range of 0.8 to 6 V. The device utilizes an open-drain output type and includes an adjustable reset delay timer, which typically operates at 55.5 ms. It functions within a supply voltage range up to 7 V and consumes a circuit current of 0.23 µA in the ON state. Qualified under AEC-Q100 Grade 1 standards, it supports operation from -40°C to +105°C.

Feature Summary

• Nano Energy™ technology enables ultra-low power consumption suitable for battery-backed systems.
• Adjustable delay timer allows customization via external capacitor connection.
• Automotive-grade reliability ensured through AEC-Q100 qualification.
• High-precision voltage detection maintains accuracy across wide temperature ranges.

Applications

• Automotive electronic control unit (ECU) monitoring
• Battery backup system supervision
• Microprocessor reset circuits in vehicles
• Voltage monitoring for safety-critical automotive modules

Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official documentation. Confirm the specific suffix matches the required package and tape-and-reel specifications. Ensure the order quantity aligns with the standard packing quantity of 3000 units per reel. Cross-reference the datasheet revision date to guarantee compatibility with current design requirements.

Selection Notes

Select this component when an adjustable delay feature is required for precise reset timing control. The open-drain output necessitates an external pull-up resistor configuration. Consider the 2.4 V threshold specifically for monitoring 3.3 V or similar logic rails. Verify that the SSOP-5 package dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to ROHM’s Nano Energy™ series of CMOS reset ICs, characterized by low current consumption and high precision. The BD52xx-2M variant specifically denotes N-channel open-drain outputs, distinguishing it from the BD53xx-2M CMOS output family. These devices are engineered to support functional safety analysis in automotive environments.

Replacement Considerations

BD52E24G-MTR is listed as a parameter-equivalent alternative. BD5220G-2MTR offers a lower 2.0 V threshold option within the same series. Verify pinout compatibility and electrical specifications before substitution.
