BU4214G-TR

Overview

The BU4214G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an adjustable delay timer and operates within a reset active voltage range of 0.7 to 7 V. The typical under-voltage detection voltage is 1.4 V with a precision of ±1%. The device utilizes an open-drain output type and provides a low-active reset signal. It consumes 0.40 μA in the ON state and 0.55 μA in the OFF state at a detection voltage of 4.8 V. The component supports a temperature range from -40°C to 125°C and is housed in an SSOP5 package.
