BD52E26G-MTR

Overview

The BD52E26G-MTR is a voltage detector IC from ROHM Semiconductor, designed for automotive applications. It features a typical threshold voltage of 2.6V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and utilizes an open-drain output type. It includes an adjustable delay timer for reset timing control. The circuit current is specified at 0.85µA when the detection voltage is 4.8V. The component is housed in an SSOP-5 package and supports functional safety analysis.

Feature Summary

• Adjustable delay timer allows customization of reset timing intervals.
• High precision voltage detection with ±1% accuracy margin.
• Open-drain output configuration for flexible interface integration.
• Automotive qualification supporting functional safety analysis requirements.

Applications

• Automotive power supply monitoring systems
• Under-voltage detection circuits
• Microcontroller reset supervision

Procurement Notes

Verify the obsolete status indicated as NRND (Not Recommended for New Designs) before procurement. Confirm availability through authorized distributors as production may be limited to existing customer support. Ensure the SSOP-5 package variant matches the required footprint. Check RoHS compliance documentation for specific material declarations. Validate that the adjustable delay feature meets the system timing requirements without external components.

Selection Notes

Select this component for designs requiring precise 2.6V monitoring with customizable reset delays. Consider the low circuit current consumption for battery-sensitive applications. The open-drain output necessitates appropriate pull-up resistor selection. Verify compatibility with the target operating temperature range. Evaluate the functional safety support level against system integrity goals.

Part Context

This part belongs to the BD52xxG-M series of voltage detectors optimized for automotive use. It shares the SSOP-5 form factor with other variants in the family but differs in threshold voltage and delay characteristics. The series emphasizes low power consumption and high reliability for vehicle electronics.

Replacement Considerations

Check for direct pin-compatible substitutes within the BD52xxG-M series with similar threshold voltages. Verify if newer generation ROHM voltage detectors offer updated features while maintaining electrical compatibility. Ensure any replacement maintains AEC-Q100 qualification if required by the application.
