BU4811G-TR

Supervisors Overview

The BU4811G-TR is a standard voltage detector manufactured by Rohm Semiconductor, designed for monitoring single-channel power supply voltages. It features an open-drain output and provides a low-active reset signal upon detecting under-voltage conditions. The device operates within a detection voltage range of 0.7V to 7V with a typical threshold of 1.1V. It supports a wide operating temperature range from -40°C to 125°C and consumes minimal current, typically 0.40μA in the ON state and 0.55μA in the OFF state at VDET=4.8V. The component is housed in a compact SSOP5 package.
