BD45275G-TR

Overview

The BD45275G-TR is a CMOS voltage detector IC from the BD45 series by ROHM Semiconductor, designed for supervisory circuit applications. It features a fixed detection threshold of 2.7V with a precision of ±1%. The device operates within a supply voltage range of 0.95V to 10V and includes a fixed reset delay time of 50ms. It utilizes an open-drain output type and supports manual reset functionality. The component is housed in an SSOP-5 package, suitable for surface mount technology, and maintains low power consumption characteristics typical of the series.

Feature Summary

• Fixed under-voltage detection threshold at 2.7V with high accuracy
• Integrated fixed 50ms reset delay timer for stable operation
• Open-drain output configuration supporting manual reset input

Applications

• Microprocessor system reset circuits
