BD5337FVE-TR

Overview

The BD5337FVE-TR is a CMOS voltage detector supervisory circuit manufactured by ROHM Semiconductor. It features a fixed detection threshold of 3.7 V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95 V to 10 V and supports a programmable reset delay timer. It utilizes a VSOF-5 surface-mount package and functions across an industrial temperature range from -40°C to +105°C. The output stage is CMOS, providing low active state reset signals without manual reset or watchdog capabilities.

Feature Summary

• CMOS output interface for direct logic integration
• Adjustable reset delay time via external resistor
• High precision voltage detection with ±1% accuracy

Applications

• Microprocessor system power monitoring
• Battery-operated device supervision
• Portable equipment voltage tracking

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity and pin alignment against the official datasheet specifications before implementation. Ensure compatibility with existing PCB footprints designed for the VSOF-5 format.

Selection Notes

Select this component when a fixed 3.7 V threshold with high accuracy is required. The programmable delay feature allows customization of reset timing without additional complex circuitry. Consider the VSOF-5 package size constraints and operating temperature range requirements during design phase.

Part Context

This component belongs to the BD53xx series of simple reset/voltage detectors. It shares functional similarities with other parts in the family but is distinguished by its specific 3.7 V threshold and VSOF-5 packaging. The series focuses on compact, low-power supervision solutions for portable electronics.

Replacement Considerations

BD5237G-1 is identified as a recommended replacement with the same pinout configuration. Verify electrical parameter compatibility and package dimensions before substitution.
