ADuM4165/ADuM4166 ABSOLUTE MAXIMUM RATINGS Table 8. THERMAL RESISTANCE Parameter Rating
Thermal performance is directly linked to PCB design and operation Supply (VBUS1, VDD1) to GND1 −0.5 V to +6.5 V environment. Close attention to PCB thermal design is required. Supply (VBUS2, VDD2) to GND2 −0.5 V to +6.5 V Upstream Input Voltage (UD−, UD+, XI θ 1, and −0.5 V to VDD1 + 0.5 V JA is the natural convection, junction to ambient thermal resistance XO measured in a one cubic foot sealed enclosure. Ψ 1) to GND1 JT is the junction Downstream Input Voltage (DD−, DD+, XI to top thermal characterization parameter. 2, −0.5 V to VDD2 + 0.5 V XO2, and PGOOD) to GND2

RI-20-1 50 2.3 °C/W Operating Range −55°C to +125°C Storage Range −65°C to +150°C 1 Test Condition 1: thermal impedance simulated with 4-layer standard JEDEC Junction (TJ Maximum) 150°C PCB. Power Dissipation2 (TJ maximum − TA)/θJA 1 Refers to common-mode transients across the insulation barrier. Common- mode transients exceeding the absolute maximum ratings may cause latch-up or permanent damage. 2 See Figure 3 for the maximum power dissipation for various temperatures. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operat- ing conditions for extended periods may affect product reliability.
Table 10. Maximum Continuous Working Voltage1 Parameter Rating Constraint
AC Voltage Bipolar Waveform Basic Insulation 650 V rms Basic insulation rating per IEC60747-17. Accumulative failure rate over lifetime (FROL) ≤ 1000 ppm at 20 years. Reinforced Insulation 600 V rms Reinforced insulation rating per IEC60747-17. Accumulative FROL ≤ 1 ppm at 26 years. Unipolar Waveform Basic Insulation 1838 VPEAK Rating limited by AC bipolar waveform accumulative FROL ≤ 1000 ppm at 20 years. Reinforced Insulation 1355 VPEAK Rating limited by package creepage per IEC 60664-1 in Pollution Degree 2 environment. DC Voltage Basic Insulation 1660 V dc Rating limited by package creepage per IEC 60664-1 in Pollution Degree 2 environment. Reinforced Insulation 830 V dc Rating limited by package creepage per IEC 60664-1 in Pollution Degree 2 environment. 1 Maximum continuous working voltage refers to the continuous voltage magnitude imposed across the isolation barrier in a Pollution Degree 2 environment.
