BU4832FVE-TR

Supervisors Overview

The BU4832FVE-TR is a CMOS voltage detector IC manufactured by ROHM Semiconductor, designed for monitoring power supply voltages. It features a typical under-voltage detection threshold of 3.2 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 and lacks manual reset, watchdog timer, or battery backup switch functionalities. The component is housed in a VSOF-5 package and is rated for operation between -40°C and +125°C.

Supervisors Feature Summary

• CMOS process technology for low current consumption
• High accuracy voltage detection with fixed threshold
• Open-drain output configuration for flexible interfacing
• Wide operating temperature range suitable for industrial environments

Supervisors Applications

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

Supervisors Procurement Notes

Verify the obsolete status and last-time-buy availability before finalizing procurement plans. Confirm RoHS compliance details through official documentation. Ensure the VSOF-5 package dimensions match the target PCB footprint. Check for any regional shipping restrictions that may apply to this discontinued component series.

Supervisors Selection Notes

Select this component when a fixed 3.2 V detection threshold is required without adjustable delay or manual reset features. Consider the open-drain output capability for level shifting applications. Evaluate the VSOF-5 package size constraints against available board space. Compare static current specifications against other low-power alternatives if extended battery life is critical.

Supervisors Part Context

This part belongs to the BU48xxFVE series of standard voltage detectors from ROHM Semiconductor. It shares architectural similarities with other members like the BU4831FVE-TR and BU4835FVE-TR, differing primarily in the specific detection threshold voltage. The series is characterized by compact packaging and CMOS efficiency.

Supervisors Replacement Considerations

The BD5232G-1TR is listed as a recommended replacement with similar specifications. Verify package compatibility as the alternative uses SSOP5 instead of VSOF-5. Confirm that the slightly different reset active voltage range (0.8 V to 6 V) meets system requirements.
