BU4835FVE-TR

Supervisors Overview

The BU4835FVE-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply levels. It features an under-voltage detection threshold of 3.5V with a precision of ±1%. The device operates within a reset active voltage range of 0.95V to 10V and utilizes an open-drain output type. Key electrical characteristics include a circuit current of 0.60μA (ON) and 0.85μA (OFF) at VS=4.8V. Hysteresis is defined as VDET x 0.05. The component is housed in a VSOF5 package and supports RoHS compliance.

Supervisors Feature Summary

• High-accuracy CMOS reset IC series with low current consumption
• Open-drain output configuration for flexible interfacing
• Wide reset active voltage range supporting various system voltages
• Integrated hysteresis to prevent output oscillation

Supervisors Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery-powered devices needing low standby current
• General-purpose voltage detection in embedded systems

Supervisors Procurement Notes

Verify the obsolete status and last-time-buy availability through official ROHM channels before procurement planning. Confirm that the VSOF5 package dimensions match your PCB footprint requirements. Ensure compatibility with the open-drain output interface for your specific logic level needs. Check for any regional distribution restrictions or lead time variations associated with end-of-life components.

Supervisors Selection Notes

Select this component when a fixed 3.5V detection threshold is required with high accuracy. Consider the VSOF5 package size constraints against available board space. Evaluate the low current consumption benefits for battery-operated applications. Verify that the open-drain output suits your downstream circuitry without requiring additional pull-up components if not already present.

Supervisors Part Context

This part belongs to the BU483x series of standard voltage detectors from ROHM Semiconductor. The series offers multiple detection voltages in 0.1V increments, allowing selection based on specific application needs. The BU4835FVE-TR specifically targets the 3.5V threshold requirement within this lineup, providing a balance of precision and power efficiency for supervisory roles.

Supervisors Replacement Considerations

The BD5235G-1 is listed as a similar specification replacement. Note differences in package (SSOP5 vs VSOF5), operating voltage range (0.8V to 6V vs 0.95V to 10V), and slightly higher precision (±0.9% vs ±1%). Verify pinout compatibility and thermal performance before substitution.
