The BU4345F is a CMOS Voltage Detector IC from ROHM Semiconductor, designed for high accuracy and low current consumption. It features an adjustable output delay controlled by an external capacitor, allowing for flexibility in application. The device operates with a detection voltage of 4.5V and offers ultra-low current consumption of approximately 0.55¬µA. It supports a wide operating temperature range from -40¬8C to +125¬8C, making it suitable for various environments. The BU4345F is available in compact packages, including SSOP5 and SOP4, which are comparable to SOT-23-5 and SC-82, respectively. This product is ideal for circuits requiring reset functions in microcontrollers or logic circuits.
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.
