IC Current Limiters Tester – IEC 62368 G.9/Table G.11 Compliance and Safety Testing Tool

IC Current Limiters Tester – IEC 62368 G.9/Table G.11 Compliance & Safety Tool

The IC Current Limiters Tester is a high-performance, fully automated testing device developed by KingPo Technology Development Limited, specifically designed to verify the current limiting performance of integrated circuits (ICs). Compliant with the latest industry standards, including IEC 62368-1 Appendix Table G.11, this IC Current Limiters Tester achieves high accuracy, efficiency, and repeatability in IC current limiting tests. By emphasizing the keyword “IC Current Limiters Tester” throughout the content, it ensures better search engine indexing and highlights its critical role in electronic component safety validation.

The IC Current Limiters Tester supports dual-channel parallel testing, enabling efficient batch verification of IC current limiting behavior under normal and fault conditions. It automatically controls load switching (short circuit, 0Ω‖470μF capacitive load, adjustable load), executes multi-step test cycles, and generates detailed reports — significantly reducing manual intervention and human error in IC current limiting tests.

Core Functions & Test Procedure

The IC Current Limiters Tester offers fully automated software control, covering the entire test process from parameter setting to result judgment.

• Software Functions:
  • Parameter input and test initiation via “IC Current Limiter Detection Software” (e.g., SPEC-230501 version)
  • Automatic generation of TXT and table reports (including tester info, parameters, results)
  • Network communication via RJ45 port (TCP connection, DHCP router support)
• Test Procedure (based on IEC 62368-1 Appendix Table G.11):
  • 8 independent test steps (e.g., tests 1, 2, 3, 7: EN end cycles; tests 4, 5, 8: input end cycles; test 6: output short circuit)
  • Automatic load branch switching (short circuit, 0Ω‖470μF capacitor, adjustable load)
  • Result judgment: Auto PASS/NG prompt, supports interruption or continuation (pop-up alert when current exceeds 120% upper limit)

 Operation Guide

The IC Current Limiters Tester simplifies the IC current limiting test process with clear, user-friendly steps:

• Device Connection:
  • Prepare 1 router, 1 PC, 2 network cables
  • Install software (copy to non-C drive)
  • Configure network (fixed IP on PC, enter device IP/port 5775 in software)
• Test Execution:
  • Input max voltage and max load current (e.g., for PW1503 IC)
  • Select test steps and cycle count
  • Click “Start Test” to run and auto-save report folder
• Calibration & Maintenance:
  • Metering mode: Daily accuracy check (limited to 16V/15A)
  • Calibration mode: Connect high-precision instrument, press SHIFT+right button to enter software, calculate and save parameters

Advantages & Applications

The IC Current Limiters Tester offers significant advantages in IC current limiting test scenarios:

• Core Advantages:
  • Full automation: Users only input parameters; device completes multi-step cycles independently
  • High precision: 1% current acquisition accuracy, supports external calibration
  • Dual-channel efficiency: Parallel testing doubles capacity
  • Compact & durable: Small footprint, reliable for lab/production use
  • Data traceability: Auto reports with historical records for failure tracing
• Application Scenarios:
  • IC current limiter development: Validate overload protection (e.g., PW1503 example)
  • Quality control: Ensure mass-produced ICs meet specification limits
  • Electronics education: Demonstrate short-circuit and overload principles

The IC Current Limiters Tester not only automates strict test procedures (such as G.11), but also supports custom parameters, making it ideal for industrial, research, and educational IC current limiting test tasks.
