BU4837FVE-TR

Supervisors Overview

The BU4837FVE-TR is a standard CMOS voltage detector IC manufactured by ROHM Semiconductor. It features an open-drain output and operates within a supply voltage range of 0.7V to 7V. The typical under-voltage detection threshold is 3.7V with a precision of ±1%. The device includes hysteresis defined as VDET x 0.05 and supports a reset active state of Low. It functions across a temperature range of -40°C to 125°C, consumes 0.40μA in the ON state and 0.55μA in the OFF state at VDET=4.8V, and provides output currents of 3.3mA (Low) and 6.5mA (High).
