BD4727G-TR

Overview

The BD4727G-TR is a standard voltage detector manufactured by ROHM Semiconductor, housed in an SSOP5 package. It features a typical under-voltage detection voltage of 2.7 V with a precision of ±1%. The reset active voltage range spans from 0.85 V to 10 V. The device utilizes an open collector output type and operates without a manual reset or watchdog timer. Circuit current consumption is 1.5 μA when ON and 1.6 μA when OFF. Hysteresis voltage is defined as Vdet multiplied by 0.05. The L output current for low voltage is 15 mA. The operating temperature range extends from -40°C to +85°C.
