BD5355FVE-TR

Overview

The BD5355FVE-TR is a voltage detector IC with an adjustable delay time, manufactured by ROHM Semiconductor. It features a CMOS output type and operates within a reset active voltage range of 0.95V to 10V. The typical under-voltage detection voltage is 5.5V with a precision of ±1%. Hysteresis voltage is defined as VDET x 0.05. Circuit current is 0.85μA at VDET=4.8V for both ON and OFF states. It lacks manual reset and watchdog timer functions. The device is housed in a VSOF5 package, measures 1.6x1.6mm with a thickness of 0.6mm, and supports a temperature range from -40°C to 105°C.
