The BU4320G 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 set using an external capacitor, making it suitable for various applications requiring reset functionality. The device operates within a detection voltage range of 2.0V, with a tolerance of ¬±1.0%, and consumes a typical current of only 0.55¬µA. It supports a wide operating temperature range from -40¬8C to +125¬8C, ensuring reliability in diverse environments. The BU4320G is available in a compact SSOP5 package, measuring 2.90mm x 2.80mm x 1.25mm, which is advantageous for space-constrained designs. This product is ideal for circuits utilizing microcontrollers or logic circuits that necessitate a reset function.
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.
