BU4214FVE-TR

Overview

The BU4214FVE-TR is a voltage detector with an adjustable delay time, manufactured by Rohm Semiconductor. It features an open-drain output 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 circuit current is 0.40 μA (ON) and 0.55 μA (OFF) at VDET=4.8V. Hysteresis voltage is VDET x 0.05. The L output current is 3.3 mA (LowVol) and 6.5 mA (HighVol). The delay circuit resistance is 10.0 MΩ. It operates from -40°C to 125°C in a VSOF5 package.
