The BD45422G is a voltage detector IC from ROHM Semiconductor, designed for applications requiring precise voltage monitoring and reset functionality. It features a detection voltage of 4.2V with a high accuracy of ¬±1.0%. The device incorporates a built-in counter timer delay circuit, eliminating the need for an external capacitor for delay time settings. It operates with ultra-low current consumption of 0.85¬µA, making it suitable for battery-powered applications. The operating temperature range is from -40¬8C to +105¬8C, ensuring reliability in various environments. The BD45422G is packaged in a compact SSOP5 format, measuring 2.90mm x 2.80mm x 1.25mm, and is available with fixed delay times of 50ms, 100ms, and 200ms. This product is ideal for circuits utilizing microcontrollers or logic circuits that require reset capabilities.
ROHM's BD45xxxG and BD46xxxG series of reset ICs utilize CMOS processes for low current consumption and high accuracy. The built-in counter timer delay circuit eliminates the need to set 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 2.3V to 4.8V, in 0.1V steps), enabling selection of the ideal solution based on customer requirements. A total of 156 models are offered, classified by delay time. In addition, the entire series is of course both lead-free and RoHS-compliant.
