  2. ½ Billion iCoupler Channels in Use Today Advancing Beyond Optocouplers • Mature Technology • Volume production since 2001 • ~ 100 product variations • Thousands of customers • High Quality and Reliability • Standard IC wafer fab and packaging technologies • Safety and Regulatory Approvals • UL, CSA/IEC, TUV, VDE • 5 kVrms reinforced isolation • Cost Effective Solutions • Integrated isolated functions

  3. iCoupler Chip-Scale Micro-TransformersIsolated Signals and Power Transformer coils transmit data in both directions, can also transfer power 20μm polyimide insulation withstands > 5kV isolation CMOS interface chips contain drive and receive circuits

  4. Detect Data Edges Encode as Pulses Decode Pulses Reconstruct Data Rising Edge Falling Edge Transfer Through Transformer iCoupler Operational Diagram

  5. Error Correction/Failsafe Circuitry • Receiver Watchdog Timer • If no pulse received within approximately 3µs, then output is set to default low • Ensures safe output state, if transmitter is not functioning properly • Transmit Refresh Circuitry • Resend Data 1µs after the last change on input • Ensures correct data state is transmitted every µsec

  6. iCoupler®Product Quality and Reliability

  7. Insulation Life vs. Voltage Across the Barrier • Polyimide Lifetime with 400Vrms is Greater than 50 Years • Lifetime at Working Voltage is Extrapolated from Empirical Data • Chart is worst case AC bipolar for Polyimide, DC and Unipolar AC is better

  8. iCoupler Isolation Capability Against Damaging Transient Voltages Withstand Voltage Waveform 1 sec 60 sec 1.2 x VISO VISO Surge Voltage Waveform VISOM 90% 50% 10% 1 Pulse / Second 50uS 1-2uS • Withstand Voltage (VISO) • Polyimide is used for Safety Isolation • 2.5 kVrms and 5kVrms • SiO2 is used for Non-safety Applications • 1 kVrmsFunctional isolation • 100% Production Tested • 1.2 x VISO for 1 second • Surge Voltage • Simulates a Lightning Strike or Other High Energy Damaging Event • >10kV Surge Required for Reinforced VDE Certification • iCoupler Products can meet >10kV and have VDE Reinforced Certification
