BD5250FVE-TR

Overview

The BD5250FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply voltages. It features an adjustable delay timer and operates within a reset active voltage range of 0.95 V to 10 V. The device detects under-voltage conditions with a typical threshold of 5.0 V and maintains a precision of ±1%. It utilizes an open-drain output type with a low active state. The circuit consumes 0.85 μA at a detection voltage of 4.8 V. Hysteresis is set at VDET x 0.05. It supports a maximum supply voltage of 10 V and functions across a temperature range of -40°C to +105°C. The component is housed in a VSOF-5 package.

Feature Summary

• Features an adjustable delay timer for customizable reset timing.
• Provides high-precision voltage detection with ±1% accuracy.
• Operates with ultra-low current consumption of 0.85 μA.
• Includes built-in hysteresis to prevent output oscillation.

Applications

• Monitoring power supply voltages in electronic systems
• Reset signal generation for microprocessors and memory devices
• Battery-powered equipment requiring reliable voltage supervision

Procurement Notes

Verify the specific ordering suffix, as the base model BD5250FVE may be available in different packaging configurations such as tape and reel or cut tape. Confirm that the VSOF-5 package dimensions align with your PCB footprint requirements. Ensure compatibility with the required operating temperature range of -40°C to +105°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a precise 5.0 V detection threshold with adjustable delay is required. It is suitable for designs needing low quiescent current and an open-drain output interface. Consider the VSOF-5 package size constraints and verify that the 10 V maximum supply voltage meets the system's input specifications. Ensure the ±1% precision satisfies the circuit's tolerance requirements.

Part Context

This part belongs to the BD52xx series of voltage detectors from ROHM Semiconductor. These components are designed for general-purpose power management applications requiring reliable supervision. The BD5250FVE-TR specifically offers an adjustable delay feature, distinguishing it from standard fixed-delay detectors in the family.

Replacement Considerations

The BD5250G-1 is listed as a recommended replacement with the same pinout. Note that the BD5250G-1 uses an SSOP5 package instead of VSOF5 and has a slightly different reset active voltage range (0.8 V to 6 V). Verify package compatibility and electrical parameter alignment before substitution.
