The BU4231FVE is a high-accuracy voltage detector IC from ROHM Semiconductor, designed for applications requiring precise voltage monitoring and reset functionality. It operates at a detection voltage of 3.1V with a tolerance of ¬±1.0%, ensuring reliable performance in critical circuits. The device features adjustable delay time, which can be set using an external capacitor, allowing for flexibility in timing applications. It consumes a low current of approximately 0.55¬µA, making it suitable for battery-powered devices. The BU4231FVE is available in a compact SSOP5 package measuring 2.90mm x 2.80mm x 1.25mm, and it operates over a wide temperature range of -40¬8C to +125¬8C. This voltage detector is ideal for use in circuits with 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. The entire series is of course both lead-free and RoHS-compliant.
