BD5240FVE-TR

Overview

The BD5240FVE-TR is a voltage detector with an adjustable delay time, currently in the last time buy status. It features a VSOF5 package and operates within a reset active voltage range of 0.95 to 10 V. The typical under-voltage detection voltage is 4.0 V with a precision of ±1%. The circuit current is 0.85 μA when on (at VDET=4.8V) and 0.85 μA when off. It has an open drain output type and does not include manual reset or watchdog timer functions. The device is RoHS compliant.

Feature Summary

• Adjustable reset delay timer functionality
• Open drain output configuration
• Wide reset active voltage range support

Applications

• General purpose voltage monitoring
• Microprocessor reset circuits
• Battery powered system supervision

Procurement Notes

Verify end-of-life status before finalizing designs. Confirm availability through authorized distributors for last-time-buy orders. Check datasheet revisions for any updated electrical characteristics or packaging changes. Ensure compatibility with existing PCB footprints and design rules.

Selection Notes

Consider the adjustable delay feature for timing requirements. Evaluate the open drain output for interface compatibility with downstream logic. Review the wide operating voltage range for system flexibility. Assess the low power consumption for battery-sensitive applications.

Part Context
