BD46372G-TR

Overview

The BD46372G-TR is a supervisory circuit manufactured by ROHM Semiconductor, functioning as a voltage detector with a fixed delay time. It features a detection threshold voltage of 3.7V and offers a reset delay timer of 200ms. The device utilizes a CMOS output type and supports manual reset functionality. It operates within a supply voltage range of 0.95V to 10V and maintains an accuracy of ±1%. The component is housed in an SSOP-5 package and is designed for surface mount installation. It supports a wide operating temperature range from -40°C to +105°C.

Feature Summary

• Fixed delay time reset function ensures stable power-on reset sequences
• CMOS output structure provides low current consumption and high noise immunity
• Manual reset input allows for external control of the reset state

Applications

• Microprocessor system power monitoring
• Embedded controller supervision
• Industrial control unit reset management

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm that the component status aligns with project lifecycle needs, as availability may vary. Cross-reference the pinout configuration with the target PCB layout to prevent integration errors during assembly.

Selection Notes

Select this component when a fixed 200ms delay is required for reliable system initialization. The CMOS output is suitable for direct interfacing with digital logic inputs. Ensure the application voltage remains within the specified operational range to maintain detection accuracy and functional integrity across the full temperature spectrum.

Part Context

This part belongs to the BD46 series of voltage detectors from ROHM. It is designed for general-purpose electronic equipment requiring precise power supervision. The series emphasizes low power consumption and compact packaging, making it suitable for space-constrained applications where reliable reset signaling is critical for system stability.

Replacement Considerations

BD5237G-1TR is a recommended replacement with the same SSOP-5 package. Note that the substitute features an open-drain output and adjustable delay, differing from the original's CMOS fixed-delay configuration.
