BU4817G-TR

Supervisors Overview

The BU4817G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a single input with an open-drain output and operates within a supply voltage range of 0.7 V to 7 V. The device provides a typical under-voltage detection threshold of 1.7 V with a precision of ±1%. It functions without manual reset or watchdog timer capabilities. The component supports surface-mount installation in an SSOP-5 package and maintains operation across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• CMOS technology ensures low power consumption suitable for battery-operated systems
• Open-drain output configuration allows flexible interfacing with various logic levels
• Wide operating voltage range accommodates diverse power supply architectures

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered equipment monitoring
• General-purpose microprocessor reset circuits

Supervisors Procurement Notes

Verify the NRND status before procurement as this component is not recommended for new designs. Confirm RoHS compliance details through official documentation. Ensure the SSOP-5 package variant matches your PCB layout requirements. Check current availability from authorized distributors due to potential lifecycle restrictions.

Supervisors Selection Notes

Select this component when a fixed 1.7 V threshold is required for system supervision. Consider the open-drain output if level shifting is needed. Evaluate the ±1% accuracy against system tolerance requirements. Verify that the absence of a watchdog timer aligns with the application's safety needs.

Supervisors Part Context

This part belongs to the BU4817G series of standard voltage detectors. It shares specifications with the BU4817G but differs in packaging format. The series is intended for general-purpose voltage monitoring where precise threshold detection is critical for system stability.
