The **ADM6328-30ARTZ-R7** is a precision voltage monitoring device manufactured by **Analog Devices**. It is primarily used as a supervisory circuit to monitor power supply voltage levels in microprocessor-based systems. --- ### ## 1. Key Specifications and Features The following table summarizes the primary technical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Threshold Voltage** | 3.00V (Fixed) | | **Output Type** | Open-Drain (Active-Low) | | **Reset Timeout** | 100 ms (minimum) | | **Supply Current** | 1 µA (Typical) | | **Operating Temperature** | -40°C to +85°C | | **Package / Case** | SOT-23-3 | | **Mounting Type** | Surface Mount | --- ### ## 2. Functional Description The ADM6328 series is designed to initiate a system reset if the power supply falls below a preset threshold. 1. **Monitoring:** The device continuously monitors the $V_{CC}$ pin. 2. **Triggering:** When $V_{CC}$ drops below 3.00V (the "30" in the part number), the $\overline{RESET}$ output transitions to a logic low state. 3. **Hysteresis:** It includes built-in immunity to supply noise and transients to prevent "chattering" or false resets. 4. **Timeout:** Once $V_{CC}$ rises above the threshold, the $\overline{RESET}$ signal remains low for a fixed "reset timeout period" (100ms) to ensure the system clock has stabilized before the processor starts. --- ### ## 3. Pin Configuration The device uses a standard 3-pin SOT-23 package: * **Pin 1 ($\overline{RESET}$):** Open-drain output. Requires an external pull-up resistor (usually connected to $V_{CC}$). * **Pin 2 (GND):** Ground reference. * **Pin 3 ($V_{CC}$):** Power supply input and monitored voltage. --- ### ## 4. Application Areas * **Microprocessor Systems:** Ensuring clean start-ups and preventing data corruption during brownouts. * **Intelligent Instruments:** Maintaining system integrity in portable devices. * **Embedded Systems:** Used in controllers where 3.3V power rails are standard. * **Battery-Powered Equipment:** Due to its ultra-low current consumption (1 µA), it is ideal for extending battery life. --- ### ## 5. Part Number Breakdown The suffix **ARTZ-R7** provides specific logistics and manufacturing info: * **ARTZ:** Refers to the SOT-23 package and RoHS compliance (Lead-free). * **R7:** Indicates that the part is shipped on a 7-inch Tape and Reel (3,000 pieces).
