Voltage Detector with Fixed Delay Time

BU45K254G series is a 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.

• Counter Timer Built-in
• No delay time setting capacitor required
• Low current consumption
• Two output types (Nch open drain and CMOS output)
• Package SSOP3 is similar to SOT-23-3 (JEDEC)
• Counter Timer Delay Time 400ms
