BD46301G-TR

Overview

The BD46301G-TR is a voltage detector IC from Rohm Semiconductor, designed for monitoring single-channel power supply voltages. It features a fixed delay time of 100ms and operates within a reset active voltage range of 0.95V to 10V. The device provides a low-active push-pull/totem pole output with a manual reset function. It supports surface mount installation in a 5-SSOP package and functions across a temperature range of -40°C to 105°C.

Feature Summary

• Includes a manual reset function for controlled system recovery
• Provides a fixed delay timer to prevent false resets during power-up
• Features a push-pull output stage for direct logic interface

Applications

• Microprocessor system supervision
• Battery-powered device power management
• Embedded controller voltage monitoring

Procurement Notes

Verify the obsolete status and last-time-buy availability before procurement planning. Confirm that the recommended replacement part BD5230G-1TR matches the required package and electrical specifications. Ensure compliance with RoHS standards and check for any specific environmental certifications required by the target application.

Selection Notes

Select this component when a fixed delay time and manual reset capability are required for voltage supervision. Compare the open-drain output of the recommended replacement against the push-pull output of this part to ensure compatibility with downstream logic circuits. Verify that the operating voltage range meets the specific system requirements.

Part Context

This component belongs to the BD46xxx series of voltage detectors manufactured by Rohm Semiconductor. It is specifically engineered for reliable power monitoring in consumer and industrial electronics. The device integrates precise detection thresholds and timing controls to ensure stable operation under varying power conditions.

Replacement Considerations

The manufacturer recommends BD5230G-1TR as a substitute. Note that the replacement features an open-drain output and adjustable delay, differing from the original's push-pull output and fixed delay.
