The BU4919F is a low voltage standard CMOS voltage detector IC from ROHM Semiconductor, designed for high accuracy and low current consumption. It features a detection voltage of 1.9V with a tolerance of ¬±1.0%, making it suitable for applications requiring precise voltage monitoring. The device operates with an ultra-low current consumption of approximately 0.55¬µA, which is beneficial for battery-powered devices. It supports a wide operating temperature range from -40¬8C to +125¬8C, ensuring reliability in various environmental conditions. The BU4919F is available in a compact SOP4 package, measuring 2.00mm x 2.10mm x 0.95mm, which is advantageous for space-constrained applications. This voltage detector is ideal for use in electronic devices that incorporate microcontrollers and logic circuits.
ROHM's low voltage standard CMOS reset ICs feature low current consumption and high precision. 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. In addition, the entire series is of course both lead-free and RoHS-compliant.
