BD5354FVE-TR

Overview

The BD5354FVE-TR is a ROHM Semiconductor voltage detector IC with a 5.4V typical detection threshold and ±1% precision. It features an adjustable delay timer controlled by an external capacitor, utilizing a 9.0 MΩ internal resistance. The device provides a CMOS output active low, operating within a reset voltage range of 0.95V to 10V. It consumes 0.85 μA at VDET=4.8V, offers hysteresis of VDET x 0.05, and supports L-output currents of 1.2 mA (Low) and 5 mA (High). It operates from -40°C to 105°C in a VSOF5 package.

Feature Summary

• CMOS output type providing active low reset signal
• Adjustable delay time via external capacitor connection
• High accuracy voltage detection with ±1% precision
• Low current consumption suitable for power monitoring

Applications

• Processor supervisor circuits
• Power supply monitoring systems

Procurement Notes

Verify the specific suffix FVE against official datasheets to confirm the VSOF-5 package and adjustable delay functionality. Confirm that the TR designation matches the required tape and reel quantity of 3000 units. Ensure the component meets RoHS standards as specified in the manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a precise 5.4V threshold with high accuracy is required. The adjustable delay feature allows customization of reset timing using an external capacitor. The CMOS output is suitable for direct interfacing with digital logic. Verify the operating temperature range and power dissipation limits match the target application environment.

Part Context

This part belongs to the BD53xx series of highly accurate, low current consumption voltage detectors. The series includes devices with CMOS outputs available for specific detection voltages ranging from 2.3V to 6.0V in 0.1V increments. The BD5354FVE-TR specifically targets the 5.4V detection point within this lineup.

Replacement Considerations

The BD5250G-1 is listed as a recommended replacement with the same pinout. Note that it has a 5.0V detection voltage, open drain output, and SSOP5 package. Verify compatibility regarding output type and threshold voltage differences.
