BU4830G-TR

Supervisors Overview

The BU4830G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply voltages. It features a threshold voltage of 3 V with an accuracy of 1%. The device operates within a supply voltage range of 900 mV to 7 V and draws a typical operating current of 550 nA. It provides an open-drain output without manual reset or watchdog timer functions. The component is housed in an SSOP-5 package and supports operation temperatures from -40°C to +125°C.

Supervisors Feature Summary

• CMOS technology enables low power consumption suitable for battery-operated applications
• Open-drain output interface allows flexible connection to various logic families
• High precision detection ensures reliable system supervision under varying conditions

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing stable voltage supervision
• Industrial control units operating in wide temperature ranges

Supervisors Procurement Notes

Verify the NRND status before procurement as this component is not recommended for new designs. Confirm availability through authorized distributors as stock may be limited. Ensure the SSOP-5 package matches your PCB footprint requirements. Check RoHS compliance documentation for environmental regulations. Validate that the 3 V threshold aligns with your specific circuit design needs.

Supervisors Selection Notes

Consider the BU4830G-TR for applications requiring precise 3 V monitoring with minimal quiescent current. The open-drain output simplifies interfacing with microcontrollers. Evaluate the -40°C to +125°C operating range against your environmental constraints. Compare performance metrics with alternative voltage detectors if higher input counts or additional features like watchdog timers are required for your specific system architecture.

Supervisors Part Context

This part belongs to the BU4830G series of standard voltage detectors from ROHM Semiconductor. It shares similar characteristics with other members of the family, differing primarily in threshold voltage settings. The series is designed for general-purpose power supply monitoring in consumer and industrial electronics. The TR suffix indicates reel packaging for automated assembly processes.
