Voltage Detector with Fixed Delay Time - BU46K304G

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.
