The BU4216F is a CMOS Voltage Detector IC from ROHM Semiconductor, designed for high accuracy and low current consumption. It features an adjustable output delay that can be controlled via an external capacitor, making it suitable for applications requiring precise timing. The detection voltage range is from 1.6V to 4.8V in 0.1V increments, with a typical accuracy of ¬±1.0%. The device operates with a low current consumption of approximately 0.55¬µA and is rated for a wide temperature range of -40¬8C to +125¬8C. It is available in compact packages, including SSOP5, SOP4, and VSOF5, which are compatible with standard footprints. This product is particularly useful in circuits that involve microcontrollers or logic circuits that require reset functionality.
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.
