Rohm Productdetail
Voltage Detector with Adjustable Delay Time - BU4242F
ROHM's low voltage CMOS reset ICs utilize CMOS processes for high precision and low current consumption. In addition, a delay circuit is built in, enabling arbitrary setting of the delay time via external capacitor. The extensive lineup includes both Nch Open Drain and CMOS output types in a wide range of detection voltages (from 0.9V to 4.8V, in 0.1V steps), enabling selection of the ideal solution based on customer requirements. Tthe entire series is of course both lead-free and RoHS-compliant.
