The BU4244F is a high-accuracy voltage detector IC from ROHM Semiconductor, designed to operate at a detection voltage of 4.4V. It features adjustable delay time, which can be set using an external capacitor, allowing for flexibility in various applications. The device is characterized by ultra-low current consumption, typically at 0.55¬µA, making it suitable for battery-powered devices. It operates over a wide temperature range of -40¬8C to +125¬8C, ensuring reliability in diverse environments. The BU4244F is available in compact packages, including SSOP5, SOP4, and VSOF5, facilitating integration into space-constrained designs. This voltage detector is ideal for circuits requiring reset functions, particularly in microcontroller and logic circuit applications.
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. The entire series is of course both lead-free and RoHS-compliant.
