### ADM6326-25ARTZ-R7: Electronic Component Overview The **ADM6326-25ARTZ-R7** is a precision voltage monitoring device manufactured by **Analog Devices**. It is primarily used as a microprocessor supervisory circuit to monitor power supply levels and provide a reset signal to a processor when the voltage falls below a specific threshold. --- ### 1. Key Technical Specifications The following table highlights the critical electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Threshold Voltage ($V_{TH}$)** | 2.5V (Standard) | | **Reset Type** | Active-Low, Push-Pull | | **Supply Voltage Range** | 1.0V to 5.5V | | **Supply Current** | 7 $\mu$A (Typical) | | **Reset Timeout Period** | 100 ms (Minimum) | | **Operating Temperature** | -40°C to +85°C | | **Package / Case** | SOT-23-3 (Surface Mount) | --- ### 2. Functional Description The ADM6326 series is designed to eliminate the need for external components in monitoring 2.5V, 3.0V, 3.3V, and 5.0V systems. #### Core Functions: 1. **Power-On Reset (POR):** When the system powers up, the device keeps the processor in a reset state for a fixed period (100ms) to ensure the power supply has stabilized. 2. **Brownout Detection:** If the supply voltage ($V_{CC}$) drops below the 2.5V threshold, the device immediately triggers a reset to prevent code execution errors or data corruption. 3. **Push-Pull Output:** Unlike open-drain outputs, the push-pull configuration does not require an external pull-up resistor, saving board space and reducing power consumption. --- ### 3. Application Use Cases This component is commonly found in low-power, space-constrained environments: * **Microprocessor Systems:** Ensuring clean startups and shutdowns. * **Critical Controllers:** Used in automotive or industrial controllers where voltage stability is vital. * **Portable Equipment:** Due to its ultra-low current consumption (7 $\mu$A), it is ideal for battery-powered devices. * **Intelligent Instruments:** Protects memory and logic states during power fluctuations. --- ### 4. Circuit Implementation Example In a typical application, the connections are minimal: ```text VCC (2.5V Supply) ----> [ VCC Pin ] GND (System Ground) --> [ GND Pin ] RESET (Active Low) --> [ Microcontroller RESET Pin ] ``` ---
