Standard Voltage Detectors - BD4944FVE

ROHM CMOS reset ICs provide low current consumption and high accuracy. The extensive lineup includes both Nch Open Drain and CMOS output types in a wide range of detection voltages (from 2.3V to 6.0V, in 0.1V steps), enabling selection of the ideal solution based on customer requirements. In addition, the entire series is of course both lead-free and RoHS-compliant.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
