BU6823G-TR

Specialized ICS Overview

The BU6823G-TR is a fractional pulse rate converter manufactured by Rohm Semiconductor, designed for precise frequency division in motor control applications. It features a fixed conversion ratio of 21:12, enabling accurate speed regulation for fan motors. The device operates within a supply voltage range supporting up to 5 mA output current while maintaining a low operating power supply current of 460 µA. It is housed in a compact 5-SSOP (SC-74A) surface-mount package and functions reliably across an extended temperature range from -40°C to +110°C.
