BD53E29G-MTR

Overview

The BD53E29G-MTR is a CMOS output voltage detector IC from Rohm Semiconductor, designed for automotive applications. It features a detection voltage of 2.9V with ±1% accuracy and an adjustable reset delay timer controlled by an external capacitor. The device operates within a supply voltage range of 0.95V to 10V and consumes ultra-low current (0.85µA typical). It is housed in a compact SSOP-5 package and meets AEC-Q100 standards.

Feature Summary

• Adjustable reset delay time via external capacitor connection
• High-precision voltage detection with ±1% tolerance
• CMOS push-pull output structure for direct logic interfacing
• Automotive-grade reliability compliant with AEC-Q100

Applications

• Microcontroller system reset circuits in automotive environments
• Power supply monitoring for electronic control units
• Logic circuit supervision requiring precise voltage thresholds

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape/reel specifications. Check for obsolescence status as this part may be restricted for new designs. Ensure compliance with RoHS directives and functional safety requirements relevant to your application.

Selection Notes

Select this component when a fixed 2.9V threshold with high precision is required. The CMOS output allows for stronger drive capability compared to open-drain variants. Consider the adjustable delay feature if noise immunity during power-up is critical. Verify that the SSOP-5 footprint fits the PCB layout constraints.

Part Context

This part belongs to the BD53Exxx series of voltage detectors characterized by free delay time settings. It serves as a specialized supervisor IC for maintaining system stability in automotive electronics. The series emphasizes low power consumption and high accuracy, targeting applications where reliable power management is essential for safety-critical functions.

Replacement Considerations

BD5335G-2CGTR is listed as a recommended replacement with similar pinout and package, though detection voltage differs. Verify electrical compatibility before substitution.
