The BU45K234G is a voltage detector IC from ROHM Semiconductor, designed for high accuracy and low current consumption. It features a built-in counter timer delay circuit, eliminating the need for an external capacitor for delay time settings. This specific model detects a voltage of 3.4V and operates with a fixed delay time of 200ms. The device supports two output types: Nch open drain and CMOS output. It has a typical current consumption of 2.3¬µA and operates within a temperature range of -40¬8C to +105¬8C. The package size is SSOP3, measuring 2.92mm x 2.80mm x 1.25mm, making it suitable for compact applications. The BU45K234G is ideal for circuits requiring reset functions in microcontroller or logic circuit applications.
ROHM’s BU45xxxxx and BU46xxxxx series are highly accurate, low current consumption voltage detector IC series. Because the counter timer delay circuit is built-in, an external capacitor for the delay time setting is unnecessary. Two output types are available (Nch open drain and CMOS output) and detection voltages range from 2.3V to 4.8V in increments of 0.1V with fixed delay time of 200ms and 400ms, that may be selected according to application.
