BD5241FVE-TR

Overview

The BD5241FVE-TR is a single-channel voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply integrity in electronic systems. It features a fixed under-voltage detection threshold of 4.1V with a precision of ±1%. The device utilizes a VSOF-5 surface-mount package and supports an operating temperature range from -40°C to +105°C. Key electrical specifications include a maximum supply voltage of 10V, low circuit current consumption of 0.85µA at Vdet=4.8V, and an open-drain output type. The reset signal is active-low, and the component includes an adjustable delay timer function.

Feature Summary

• Provides precise under-voltage detection with a fixed 4.1V threshold and ±1% accuracy.
• Features an adjustable delay timer to control reset timing relative to voltage changes.
• Delivers an active-low reset signal via an open-drain output interface.
• Operates within a wide industrial temperature range of -40°C to +105°C.

Applications

• Monitoring battery voltage levels in portable electronic devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance and specific tape-and-reel packaging requirements (3000 units) prior to ordering. Cross-reference datasheet revisions to ensure compatibility with existing design constraints and regulatory standards.

Selection Notes

Select this component when a fixed 4.1V threshold with high precision is required. Consider the adjustable delay feature if timing synchronization with other system events is necessary. Ensure the open-drain output configuration aligns with the target logic level and pull-up resistor requirements of the monitored circuit.
