BU4841FVE-TR

Supervisors Overview

The BU4841FVE-TR is a standard CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It features a typical under-voltage detection threshold of 4.1 V with a precision of ±1%. The device operates within a reset active voltage range of 0.7 V to 7 V and supports a maximum supply voltage of 7 V. It utilizes an open-drain output type with a low active reset state. The component functions across an extended temperature range from -40°C to +125°C and consumes a circuit current of approximately 0.40 μA when active at 4.8 V.

Supervisors Feature Summary

• CMOS technology ensures high accuracy and low current consumption for efficient power management.
• Open-drain output provides flexible interface compatibility with various digital logic families.
• Extended operating temperature range supports reliable performance in harsh industrial environments.

Supervisors Applications

• Microprocessor system reset circuits
• Portable equipment power supervision
• Battery-operated device voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix FVE-TR against the official datasheet to confirm package type and tape-and-reel specifications. Confirm end-of-life status as the part may be obsolete or subject to last-time-buy restrictions. Ensure RoHS compliance documentation matches current regulatory requirements for your region before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.1 V threshold is required for single-supervision applications. Consider the open-drain output requirement for pull-up resistor integration. Evaluate the SSOP-5 package constraints against PCB layout limitations. Verify that the ±1% precision meets the system's tolerance requirements without needing external calibration.

Supervisors Part Context

This part belongs to the BU48xx series of standard voltage detectors, which offers a wide range of detection voltages from 0.9 V to 4.8 V in 0.1 V increments. The series is characterized by high accuracy and low power consumption, making it suitable for general-purpose supervisory roles in consumer and industrial electronics where precise voltage monitoring is critical.

Supervisors Replacement Considerations

BD5241G-1 is listed as a similar specification replacement with comparable voltage thresholds and output types. Verify pinout compatibility and package dimensions (SSOP-5 vs. alternative) before substitution. Check if the replacement maintains the same reset active state and hysteresis characteristics for direct interchangeability.
