BD52E28G-MTR

Overview

The BD52E28G-MTR is an adjustable delay voltage detector designed for automotive applications, manufactured by ROHM Semiconductor. It features a typical under-voltage detection threshold of 2.8 V with ±1% precision. The device operates within a reset active voltage range of 0.95 to 10 V and utilizes an open-drain output type. It supports an adjustable reset delay timer controlled by an external capacitor and maintains a low circuit current of 0.85 µA at VDET=4.8V. The component is housed in an SSOP5 package, complies with AEC-Q100 standards, and includes copper wire bonding technology.

Feature Summary

• Adjustable delay time controlled by an external capacitor
• Automotive-grade reliability compliant with AEC-Q100
• Copper wire bonding construction for enhanced durability

Applications

• Automotive power supply monitoring systems
• Voltage supervision for electronic control units
• Reset signal generation for microcontrollers

Procurement Notes

Verify the specific suffix and packaging configuration against official ROHM documentation before procurement. Confirm that the component status aligns with existing design support requirements, as this part may be restricted from new designs. Ensure compatibility with automated assembly processes given the SSOP5 taping format.

Selection Notes

Select this component when an adjustable delay function is required for automotive voltage monitoring. Consider the specific 2.8 V detection threshold and the need for external capacitor integration for timing control. Evaluate the trade-off between the higher circuit current compared to newer nano-energy series and the established availability for legacy automotive platforms.

Part Context

This part belongs to the BD52E series of voltage detectors, which are specialized for automotive environments. The 'M' suffix typically denotes specific manufacturing or material variations, such as the copper wire bonding feature mentioned in official specifications. It serves as a robust solution for critical system resets where delay adjustability is essential.

Replacement Considerations

Official replacement data indicates BD5228G-1TR as a recommended alternative with the same pinout and package. Verify functional equivalence regarding delay adjustability and electrical parameters before substitution.
