The **ADM8613Z232ACBZ-R7** is a high-performance, ultra-low power supervisory circuit manufactured by **Analog Devices**. It is primarily used to monitor power supply voltages in microprocessor-based systems. --- ## 1. Technical Specifications Below are the primary electrical and physical characteristics of the device: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Analog Devices Inc. | | **Function** | Voltage Supervisor / Reset IC | | **Threshold Voltage ($V_{TH}$)** | 2.32V | | **Supply Current ($I_{CC}$)** | 920 nA (Typical) | | **Reset Timeout** | 140 ms (Minimum) | | **Output Type** | Push-Pull, Active-Low | | **Package / Case** | 4-Ball WLCSP (Wafer Level Chip Scale Package) | | **Operating Temperature** | -40°C to +85°C | --- ## 2. Key Features The ADM8613 series stands out due to its integration of multiple monitoring functions into a microscopic footprint: * **Ultra-Low Power Consumption:** Consuming less than $1 \mu A$, it is ideal for battery-operated devices (IoT, wearables). * **Manual Reset (MR) Input:** Allows the user or another digital circuit to trigger a reset regardless of the voltage levels. * **Watchdog Timer (WDI):** It monitors the microprocessor's activity. If the processor fails to "pet" the watchdog (toggle the WDI pin) within a specific window, the chip issues a system reset. * **Compact Form Factor:** The WLCSP package measures approximately 1mm x 1mm, saving significant PCB real estate. --- ## 3. Pin Configuration & Logic The device typically operates in a 4-ball grid arrangement: | Pin | Name | Description | | :--- | :--- | :--- | | **A1** | **VCC** | Power Supply Input / Monitored Voltage | | **A2** | **GND** | Ground | | **B1** | **$\overline{RESET}$** | Active-Low Output (Transitions low if VCC < $V_{TH}$) | | **B2** | **WDI / MR** | Combined Watchdog Input and Manual Reset | --- ## 4. Typical Application Circuit When integrating this part into a design, the $\overline{RESET}$ pin is connected directly to the `RESET` pin of a Microcontroller (MCU). ```c // Pseudo-logic for Watchdog Interaction while(system_running) { perform_tasks(); kick_watchdog(); // Toggle WDI pin to prevent ADM8613 from resetting the MCU if (power_failure) { // ADM8613 automatically pulls RESET low at 2.32V } } ``` --- ## 5. Part Number Breakdown The suffix **Z232ACBZ-R7** contains specific ordering information: * **Z**: RoHS Compliant. * **232**: Represents the 2.32V threshold. * **CBZ**: Refers to the WLCSP package type. * **R7**: Indicates 7-inch tape and reel packaging (typically 3,000 units).
