BD5235G-TR

Overview

The BD5235G-TR is a voltage detector IC from ROHM Semiconductor, designed for monitoring supply voltages. It features an adjustable delay timer and operates within a reset active voltage range of 0.95 V to 10 V. The typical under-voltage detection threshold is 3.5 V with a precision of ±1%. It utilizes an open-drain output type and maintains low circuit current consumption of 0.85 μA at VDET=4.8V in both ON and OFF states. The device supports a hysteresis voltage of VDET x 0.5 and offers L-level output currents of 0.4 mA and 2 mA respectively. It functions reliably across a temperature range of -40°C to +105°C.
