The BU45K332G is a voltage detector IC from ROHM Semiconductor, designed for applications requiring precise voltage monitoring. It features a detection voltage of 3.3V with a high accuracy of ¬±1.0%. The device operates with low current consumption, typically at 2.3¬µA, making it suitable for battery-powered applications. The built-in counter timer eliminates the need for an external capacitor for delay time settings, offering fixed delay options of 200ms and 400ms. The operating temperature range is from -40¬8C to +105¬8C, ensuring reliability in various environments. The package size is SSOP3, measuring 2.92mm x 2.80mm x 1.25mm, which is compatible with SOT-23-3. This product is ideal for circuits utilizing microcontrollers or logic circuits that require reset functionality.
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.
