The BU45L312G 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. The device supports two output types: Nch open drain and CMOS output. It offers detection voltages of 2.3V, 2.4V, 2.6V, 2.9V, 3.0V, 3.3V, 3.6V, 4.0V, and 4.2V, with fixed delay times of 200ms and 400ms, selectable based on application requirements. The operating temperature range is from -40°C to +105°C, making it suitable for various environments. The package size is SSOP3, measuring 2.92mm x 2.80mm x 1.25mm. This product is ideal for circuits that require reliable voltage detection and reset functionality in microcontroller 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.
