The **88C56L-AF5-R** is a specific part number typically associated with high-precision voltage detectors or reset ICs, commonly manufactured by vendors like **UTC (Unisonic Technologies)**. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Overview This component is a **CMOS-based voltage detector** designed to monitor power supply rails. Its primary function is to trigger a reset signal when the voltage drops below a specified threshold, ensuring that microprocessors or digital circuits do not operate under unstable power conditions. ### 2. Technical Specifications Based on the part numbering convention, the key technical parameters are outlined in the table below: | Feature | Specification | | :--- | :--- | | **Component Type** | Voltage Detector / Reset IC | | **Detection Voltage** | 5.6V (indicated by '56') | | **Output Configuration** | CMOS Output (Active Low) | | **Operating Voltage Range** | 0.7V to 10V (Typical) | | **Ultra-Low Current Consumption** | ~1.0µA to 3.0µA | | **Package Type** | SOT-25 (indicated by 'AF5') | | **Operating Temperature** | -40°C to +85°C | | **Lead-Free Status** | Halogen Free / RoHS Compliant ('R') | --- ### 3. Pin Configuration (SOT-25) The AF5 package (SOT-25) typically follows this pinout structure: 1. **Vout**: Output Pin (Sends the reset signal). 2. **Vdd**: Power Supply/Input Voltage Sense. 3. **Vss**: Ground. 4. **NC/CD**: No Connection or Delay Capacitance (depending on specific sub-series). 5. **NC**: No Connection. --- ### 4. Part Number Decoder Understanding the suffix codes helps in identifying the exact variant: * **88C**: Series designation for CMOS Voltage Detectors. * **56**: Threshold Voltage (5.6 Volts). * **L**: Accuracy Class (typically ±2%). * **AF5**: Package code for **SOT-25**. * **R**: Packing code (Tape & Reel) and Lead-free/Halogen-free requirements. --- ### 5. Common Applications * **Microprocessor Reset**: Provides a clean reset signal during power-up or brown-out conditions. * **Battery Monitoring**: Prevents deep discharge by signaling when battery voltage is low. * **Level Discriminator**: Used in circuits that require a logic change at a specific voltage level. ---
