BU4913FVE-TR

Supervisors Overview

The BU4913FVE-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages. It features a CMOS output type with a typical under-voltage detection threshold of 1.3 V and a precision of ±1%. The reset active voltage range spans from 0.7 V to 7 V, accommodating various system requirements. Operating current is specified at 0.40 μA when ON and 0.55 μA when OFF at a detection voltage of 4.8 V. The device includes hysteresis set at VDET x 0.5% and supports an L-output current of 3.3 mA (Low) and 6.5 mA (High). It operates within a temperature range of -40°C to 125°C and is housed in a VSOF5 package measuring 1.6x1.6 mm with a thickness of 0.6 mm.

Supervisors Procurement Notes

Verify the specific ordering suffix TR for tape-and-reel configuration against official ROHM documentation. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer. Ensure the VSOF5 package dimensions match PCB footprint specifications prior to procurement. Check for any regional distribution restrictions or end-of-life notices associated with this component variant.

Supervisors Selection Notes

Select this component when a fixed 1.3 V detection threshold with high precision is required. Consider the CMOS output drive capability for direct interfacing with digital logic. Evaluate the wide reset voltage range compatibility with system rail variations. Assess thermal performance within the specified -40°C to 125°C operational envelope for environmental suitability.

Supervisors Part Context

The BU4913FVE-TR belongs to ROHM's standard voltage detector family, offering reliable supervision for single-channel applications. It complements other variants in the series by providing specific threshold options and package configurations. The VSOF5 package represents a compact solution compared to larger SOP packages found in related parts like the BU4911F.

Supervisors Replacement Considerations

The BD5213G-1 is documented as a recommended replacement with similar specifications. Verify package compatibility between VSOF5 and SSOP5 during transition. Confirm electrical parameter alignment, particularly the 1.3 V detection threshold and ±1% precision, to ensure circuit functionality remains unchanged.
