The BU45L334G 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 device offers two output types: Nch open drain and CMOS output. The detection voltage for this part is set at 3.3V, with a high accuracy of ¬±1.0%. The device operates within a temperature range of -40¬8C to +105¬8C and consumes a typical current of 2.3¬µA. The fixed delay times available are 200ms and 400ms, making it suitable for applications requiring precise voltage monitoring and reset functions in microcontroller or logic circuit environments. The package size is SSOP3, measuring 2.92mm x 2.80mm x 1.25mm.
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.
