BD52E29G-MTR

Overview

The BD52E29G-MTR is an adjustable delay voltage detector designed for automotive applications. It features a typical under-voltage detection threshold of 2.9 V with ±1% precision. The device supports a reset active voltage range from 0.95 V to 10 V and utilizes an open-drain output type. Key electrical parameters include a circuit current of 0.85 µA at VDET=4.8 V, hysteresis voltage defined as VDET x 0.05, and low/high output currents of 0.4 mA and 2 mA respectively. The internal delay circuit resistance is 9 MΩ. It operates within a temperature range of -40°C to 105°C and is housed in an SSOP5 package.

Feature Summary

• Delay time is controlled by an external capacitor connected to the device.
• Designed to support functional safety analysis for automotive use cases.
• Utilizes copper wire bonding technology for enhanced reliability.

Applications

• Automotive electronic system monitoring
• Under-voltage detection circuits
• Power management supervision

Procurement Notes

This component is designated as Not Recommended for New Designs (NRND) and is produced solely to support existing customers. Verify that the current design can accommodate this status change. Confirm compatibility with the SSOP5 package and taping specifications before finalizing procurement plans for legacy systems.

Selection Notes

Select this part only if maintaining continuity with existing automotive designs requiring a 2.9 V threshold. Note that newer alternatives like the BD52xxG-1 series offer improved current consumption and broader voltage ranges. Ensure the application specifically requires the NRND status constraints and the specific delay characteristics provided by the external capacitor method.

Part Context

The BD52E29G-MTR belongs to the BD52xxG-M series of adjustable delay voltage detectors. This series is characterized by its ability to set reset delays via external components and its focus on automotive-grade reliability. It serves as a specialized solution for power supervision where precise timing control and high accuracy are required in vehicle electronics.

Replacement Considerations

The BD5229G-1TR is documented as a replacement product with the same pinout and package. It offers similar functionality but may differ in current consumption and operating voltage ranges. Verify technical compatibility before substitution.
