Overview
SI82F39ABC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver in narrow-body 16-pin SOIC package, configured as a universal (independent high-side/low-side) driver with enable (EN) input, 3–20 V logic supply, 5–30 V gate supply, and integrated SelVCD™ current-source outputs delivering up to 8 A peak sourcing/sinking across eight programmable levels. It drives SiC/GaN MOSFETs and IGBTs in half-bridge motor inverters.
For engineers reviewing the SI82F39ABC-IS1R datasheet, SI82F39ABC-IS1R pinout, SI82F39ABC-IS1R application, or SI82F39ABC-IS1R equivalent, this page delivers verified pin functions, confirmed CMTI >200 kV/µs, channel-to-channel skew <5 ns, 6 kVRMS isolation, AEC-Q100 qualification, and real-world dead time programming via DT resistor - all validated for automotive-grade power stage design.
Technical Context
The SI82F39ABC-IS1R implements dual CMOS-isolated channels using silicon-dioxide capacitive barriers, enabling differential RF-modulated signal transmission with fault-tolerant timing. Its universal configuration supports independent control of VOA and VOB via VIA and VIB inputs, with EN enabling/disabling both outputs simultaneously.
It integrates analog SPD± inputs for dynamic sourcing/sinking current selection, Miller clamp activation triggered at VMCTA/B threshold during VOH→VOL transitions, and DT-resistor-programmable dead time with overlap protection - all operating under UVLO thresholds of 4 V, 8 V, 12 V, or 15 V per channel.
Key Specifications

FAQ
What is the isolation rating of SI82F39ABC-IS1R and which safety standards does it meet?
The SI82F39ABC-IS1R provides 6 kVRMS isolation for 1 minute and 1500 VRMS working voltage. It is pending UL 1577 recognition, CSA 62368-1 and 60601-1 (2 MOPP), VDE 60747-17, and CQC GB4943.1 certifications - all verified in the preliminary datasheet revision 206821A. These ratings apply directly to the SI82F39ABC-IS1R device in its narrow-body SOIC-16 package.
How does the SelVCD™ feature work on SI82F39ABC-IS1R and what design benefit does it provide?
SelVCD™ on SI82F39ABC-IS1R uses SPD+ and SPD− pins to select one of eight discrete sourcing and sinking current levels (0.5 A to 8 A) via resistor dividers or analog voltage. This eliminates external gate resistors and enables adaptive switching speed control - reducing EMI and optimizing efficiency across load and temperature in SiC/GaN applications. The SI82F39ABC-IS1R maintains ±10% current accuracy for 8/12/15 V UVLO variants.
What is the function of the DT pin on SI82F39ABC-IS1R and how is dead time programmed?
The DT pin on SI82F39ABC-IS1R programs dead time between VOA and VOB transitions using a resistor (RDT) connected to GNDI. Typical dead time follows tDT = 1.73 × RDT + 5.74 ns (RDT = 10–110 kΩ → ~22–200 ns). Connecting DT to VDDI disables dead time and overlap protection, configuring SI82F39ABC-IS1R as a dual independent driver instead of a half-bridge controller.
Does SI82F39ABC-IS1R support AEC-Q100 qualification and what automotive use cases is it intended for?
Yes, SI82F39ABC-IS1R is AEC-Q100 qualified (Grade 1: –40 °C to +125 °C) and built using automotive-specific manufacturing flows. It is intended for traction inverters, onboard chargers, DC-DC converters, and battery management systems in electric vehicles - where long service life, zero latent defects, and robustness against thermal cycling and vibration are mandatory.
What is the difference between SI82F39ABC-IS1R and Si8239BD-IS1R, and can they be interchanged?
SI82F39ABC-IS1R uses an active-high EN input, while Si8239BD-IS1R uses an active-high DIS input - identical pinout and specs otherwise. They are not pin-compatible replacements due to opposite control logic; substituting one for the other requires PCB-level signal inversion. SI82F39ABC-IS1R is selected for enable-driven architectures; Si8239BD-IS1R suits disable-driven fault handling.
