BU4314G-TR

Overview

The BU4314G-TR is a voltage detector with adjustable delay time, manufactured by ROHM Semiconductor. It features an under-voltage detection voltage of 1.4V with a precision of ±1%. The reset active voltage range spans from 0.7V to 7V. The output type is CMOS, and the reset delay timer is adjustable. The reset active state is low, with no manual reset or watchdog timer functionality. The circuit current is 0.40μA (ON) and 0.55μA (OFF) at VDET=4.8V. Hysteresis voltage is VDET x 0.05. L output current is 3.3mA (LowVol) and 6.5mA (HighVol). The delay circuit resistance is 10.0MΩ. Operating temperature ranges from -40°C to 125°C. Package is SSOP5.
