BD4832FVE-TR

Overview

The BD4832FVE-TR is a standard voltage detector manufactured by Rohm Semiconductor, designed for monitoring single-channel supply voltages. It operates within a wide supply voltage range of 0.95V to 10V and features a typical under-voltage detection threshold of 3.2V with ±1% precision. The device utilizes an open-drain output configuration that provides a low-active reset signal without an internal delay timer. Packaged in a compact VSOF5 (SOT-665) surface-mount format, it supports reflow soldering processes. The component functions reliably across an industrial temperature range from -40°C to 105°C, ensuring stable performance in various electronic applications requiring precise power supervision.

Feature Summary

• Provides accurate voltage supervision with high detection precision for reliable system monitoring
• Features an open-drain output interface compatible with various logic families for flexible integration
• Operates effectively across a broad supply voltage range suitable for diverse power architectures
• Maintains stable functionality within extended industrial temperature environments

Applications

• Monitoring microprocessor and microcontroller power supplies
• Supervising battery-powered equipment voltage levels
• Ensuring system stability in portable electronic devices
• Providing reset signals for digital logic circuits

Procurement Notes

Verify the current manufacturing status as this component may be discontinued or subject to last-time buy restrictions. Confirm compatibility with the replacement part BD5232G-1TR if sourcing new inventory, noting potential package differences between VSOF5 and SSOP5. Ensure all technical specifications align with design requirements before procurement.

Selection Notes

Select this component when a fixed 3.2V threshold with high accuracy is required for single-channel voltage monitoring. Consider the open-drain output capability for interfacing with different logic levels. Evaluate the VSOF5 package size constraints against available board space. Verify thermal performance requirements against the specified operating temperature range for the intended application environment.

Part Context

This voltage detector belongs to Rohm's standard supervisor series, focusing on cost-effective and reliable power management solutions. It serves as a fundamental building block for ensuring proper system initialization and operation by detecting abnormal voltage conditions. The component complements other PMIC offerings by providing dedicated supervision functions without complex programmability.

Replacement Considerations

The BD5232G-1TR is a recommended replacement with similar electrical specifications. Note that the substitute uses an SSOP5 package instead of VSOF5, requiring layout adjustments. The replacement offers adjustable delay timers and slightly improved current consumption characteristics.
