BU4829G-TR

Supervisors Overview

The BU4829G-TR is a CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring single-input supply voltages. It features an open-drain output and operates within a power supply range of 0.7 V to 7 V. The typical threshold voltage is 2.9 V with a precision of ±1%. The device supports adjustable reset delay timers and functions across a temperature range of -40°C to +125°C. It consumes low current, typically 0.40 μA in the ON state and 0.55 μA in the OFF state at VDET=4.8V. Hysteresis is set at VDET x 0.05. The component is housed in an SSOP-5 package.
