BD48E40G-MTR

Overview

The BD48E40G-MTR is a standard voltage detector designed for automotive applications, manufactured by Rohm Semiconductor. It features an under-voltage detection threshold of 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 set to Vs x 0.05 and supports an operating temperature range from -40°C to 105°C.
