BD53E27G-MTR

Overview

The BD53E27G-MTR is an adjustable delay time voltage detector designed for automotive applications, certified to AEC-Q100 standards. It features a typical under-voltage detection threshold of 2.7 V with ±1% precision and a reset active voltage range from 0.95 V to 10 V. The device utilizes a CMOS output type with a low-active reset state and consumes 0.85 µA in both ON and OFF states at VDET=4.8V. It operates within a temperature range of -40°C to 105°C and is housed in an SSOP5 package.

Feature Summary

• Adjustable reset delay timer controlled by an external capacitor
• Automotive-grade functional safety support capability
• High-precision voltage detection with minimal current consumption

Applications

• Automotive electronic system monitoring
• Voltage supervision for engine control units
• Power management circuit protection

Procurement Notes

This component is designated as not recommended for new designs (NRND) and is produced solely to support existing customers. Verification of the specific supply status and obsolescence timeline is required before procurement. Ensure compatibility with legacy systems, as availability may be limited or subject to change without notice.

Selection Notes

Select this part only for maintaining existing automotive designs requiring a 2.7 V detection threshold with adjustable delay. Verify that the SSOP5 package and CMOS output characteristics align with the original schematic. Consider alternative NRND parts or newer series if redesigning, as this component is no longer promoted for new projects.

Part Context
