BU4833G-TR

Supervisors Overview

The BU4833G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply lines. It operates within a supply voltage range of 0.7 V to 7 V and features a typical threshold detection voltage of 3.3 V with ±1% precision. The device utilizes an open-drain output configuration and lacks manual reset or watchdog timer functions. It is housed in an SSOP-5 package and supports surface-mount installation. The component is rated for operation between -40°C and +125°C, with a maximum power dissipation of 540 mW.

Supervisors Feature Summary

• Provides precise voltage supervision with high accuracy for reliable system monitoring
• Features low power consumption suitable for battery-operated applications
• Offers flexible integration via open-drain output without requiring external components

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing stable voltage supervision

Supervisors Procurement Notes

Verify the current lifecycle status before procurement, as this component may be designated as not recommended for new designs. Confirm that the SSOP-5 package dimensions align with existing PCB footprints. Ensure compatibility with the target application's voltage requirements, specifically the 3.3 V threshold. Check for RoHS compliance documentation if required by regulatory standards. Validate that the open-drain output interface matches the receiving circuit's logic levels.

Supervisors Selection Notes

Select this component when a fixed 3.3 V detection threshold is required for single-channel monitoring. Consider the SSOP-5 package size constraints during layout planning. Evaluate the open-drain output capability against the system's pull-up resistor requirements. Assess the operating temperature range suitability for the intended environment. Compare performance metrics against alternative supervisors if adjustable thresholds are needed.

Supervisors Part Context

This part belongs to the BU483xG series of standard voltage detectors from ROHM Semiconductor. The series includes variants with different detection thresholds, such as the BU4832G and BU4836G, sharing similar package and functional characteristics. These components are commonly used in power management integrated circuits (PMIC) for supervisory applications.

Supervisors Replacement Considerations

The BD5233G-1 is listed as a replacement option with similar specifications. Verify package compatibility, as the BD5233G-1 may utilize a different footprint. Confirm electrical parameter alignment, particularly the detection voltage and output type.
