BD5240G-2MTR

Overview

The BD5240G-2MTR is a Nano Energy™ adjustable delay voltage detector IC designed for automotive applications. It features a 4.0V typical threshold voltage with ±2.5% precision and an open-drain output. The device operates within a supply voltage range of 0.8V to 7V, consuming 0.23µA in the ON state and 0.27µA in the OFF state. It includes a programmable reset delay timer set by an external capacitor, providing a hysteresis voltage of VDET x 0.05. Qualified under AEC-Q100 Grade 1, it functions reliably from -40°C to 105°C.

Feature Summary

• Nano Energy™ low power consumption architecture
• Adjustable reset delay time via external capacitor
• Automotive grade AEC-Q100 qualification
• High precision voltage detection with hysteresis

Applications

• Automotive electronic control unit monitoring
• Battery voltage supervision systems
• Power management circuit resets

Procurement Notes

Verify the specific suffix '2MTR' corresponds to the SSOP-5 tape and reel packaging configuration. Confirm that the component meets the required functional safety category FS supportive standards for your target application. Ensure the external capacitor selection aligns with the desired delay timing specifications defined in the official datasheet.

Selection Notes

Select this component when an adjustable delay timer is required rather than a fixed delay. It is suitable for designs needing precise voltage monitoring with low standby current. Consider the open-drain output capability for interfacing with various logic levels. Verify that the 4.0V threshold matches the system's critical voltage detection requirements.

Part Context

This part belongs to the BD52xxG-M series of CMOS reset ICs from ROHM Semiconductor. The series utilizes CMOS processes for high accuracy and low current consumption. It offers a lineup of detection voltages from 0.9V to 5.0V in 0.1V steps. The BD5240G-2MTR specifically provides the Nch open-drain output variant within this family.

Replacement Considerations

BD5240G-2M is a similar specification alternative with identical electrical characteristics but different packaging.
