BD4828FVE-TR

Overview

The BD4828FVE-TR is a standard CMOS voltage detector IC manufactured by Rohm Semiconductor. It features an N-ch open drain output and operates within a supply voltage range of 0.95V to 10V. The typical under-voltage detection threshold is set at 2.8V with a precision of ±1%. The device consumes ultra-low current, typically 0.60μA when active and 0.85μA in standby at Vs=4.8V. It includes hysteresis voltage defined as Vs x 0.05 and supports an operating temperature range from -40°C to 105°C. The component is housed in a VSOF5 package.

Feature Summary

• Provides high-accuracy voltage monitoring with ±1.0% detection voltage precision for reliable system supervision.
• Features ultra-low current consumption characteristics suitable for battery-powered or energy-efficient applications.
• Utilizes an N-ch open drain output configuration compatible with various logic families.

Applications

• Microcontroller reset circuits requiring precise voltage supervision
• Logic circuit power management and monitoring
• Electronic devices needing low-power voltage detection

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of recommended replacement components such as the BD5228G-1 series. Ensure that the VSOF5 package dimensions are compatible with existing PCB layouts if substituting. Check RoHS compliance documentation for final assembly requirements.

Selection Notes

Select this component for applications requiring a fixed 2.8V detection threshold with open-drain output. Consider the VSOF5 package size constraints and the specified operating temperature range. Evaluate the current consumption specifications against system power budgets. Verify compatibility with the target microcontroller or logic input levels.

Part Context

This component belongs to the BD48xx series of standard voltage detectors from Rohm Semiconductor. The series offers multiple detection voltages in 0.1V increments and different output types. The BD4828FVE-TR specifically provides a 2.8V threshold with an open-drain output in a compact VSOF5 package, targeting general-purpose electronic device supervision.

Replacement Considerations

The BD5228G-1TR is listed as a recommended replacement with similar specifications. Note that the substitute uses an SSOP5 package instead of VSOF5, requiring mechanical adaptation. Both parts share the same 2.8V detection voltage and open-drain output type.
