BD49E27G-MTR

Overview

The BD49E27G-MTR is a high-accuracy voltage detector designed for automotive applications, manufactured by ROHM Semiconductor. It features a CMOS output type and operates within a reset active voltage range of 0.95 V to 10 V. The device detects an under-voltage threshold of 2.7 V with a precision of ±1%. It does not include a manual reset or watchdog timer function. The component is housed in an SSOP-5 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• High accuracy detection capability
• Ultra-low current consumption
• Automotive grade qualification

Applications

• Automotive electronic systems monitoring
• Power management circuit supervision
• Voltage level detection in vehicle electronics

Procurement Notes

Verify the supply status as Not Recommended for New Designs (NRND) before procurement. Confirm that the SSOP-5 package matches the target footprint. Ensure the design supports existing customer needs rather than new development cycles due to the lifecycle status.

Selection Notes

Select this component when a fixed 2.7 V threshold is required for automotive voltage monitoring. The CMOS output and lack of delay timer suit simple supervision tasks. Verify compatibility with the 0.95 V to 10 V reset active range against system power rails.

Part Context

This part belongs to the BD49E series of standard voltage detectors optimized for automotive use. It shares functional similarities with other models in the family but is distinguished by its specific 2.7 V threshold and CMOS output configuration. The series emphasizes low power consumption and high precision for reliable vehicle operation.

Replacement Considerations

BD5227G-1 is a recommended replacement with the same SSOP-5 package. Note that the substitute offers adjustable delay and open-drain output, differing from the original's fixed timing and CMOS output.
