BD48E44G-MTR

Overview

The BD48E44G-MTR is a standard voltage detector manufactured by Rohm Semiconductor, designed for automotive applications. It features an under-voltage detection threshold of 4.4V with a precision of ±1%. The device operates within a reset active voltage range of 0.95V to 10V and utilizes an open-drain output type with a low-active reset state. It consumes 0.60µA in the ON state and 0.85µA in the OFF state at Vs=4.8V. The component includes hysteresis voltage defined as Vs x 0.05 and supports L-output currents of 0.4mA (LowVol) and 2mA (HighVol). It is housed in an SSOP5 package measuring 2.9x2.8mm with a thickness of 1.25mm, operating between -40°C and 105°C.
