Product Description

The R3114N181A-TR-FE is a voltage detector IC from the R3114 series, designed for precise power monitoring in compact systems. Packaged in SOT-23-5, it operates within a 1.6V to 6.0V input range, delivering a fixed 1.81V detection threshold for low-voltage reset applications. This single-channel device provides an open-drain output directly interfacing with microcontroller reset circuits or power management modules. With ultra-low quiescent current (1.0μA typ.), it ensures minimal power drain while supporting -40°C to +105°C operation, ideal for automotive, industrial controls, and consumer electronics. Advantages include high accuracy (±1.5%) and fast response, though it lacks adjustable detection thresholds. The R3114N181A excels in space-constrained designs requiring reliable voltage supervision without external components.
