Product details
Overview
SI82E39ABC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with 6 A peak output current, designed for high-side/low-side half-bridge control in SiC and GaN power stages. It features 6 kVRMS reinforced isolation, <5 ns channel-to-channel skew, CMOS inputs, and programmable dead time via external resistor. It drives power switches in onboard chargers and motor inverters requiring robust noise immunity and precise timing.
For engineers reviewing the SI82E39ABC-IS1R datasheet, SI82E39ABC-IS1R pinout, SI82E39ABC-IS1R application, or SI82E39ABC-IS1R equivalent, key selection criteria include its 6 A drive strength, 200 kV/µs CMTI, universal/high-side-low-side pinout flexibility, automotive-grade AEC-Q100 qualification, and support for 3–20 V logic supply with UVLO options at 4/8/12/15 V.
Technical Context
The SI82E39ABC-IS1R implements capacitive silicon-dioxide (SiO₂) isolation with differential RF-modulated OOK signaling, enabling high fault tolerance and low propagation delay variation across temperature and lifetime. Its dual-channel architecture supports both independent input (VIA/VIB) and PWM-input modes, with configurable EN/DT pins for enable control and dead-time programming.
It integrates independent undervoltage lockout (UVLO) on VDDI, VDDA, and VDDB rails, thermal shutdown with hysteresis, short-circuit clamping to VDDA/B, and active pull-down shutdown clamps on unpowered outputs - all operating within –40 to +125 °C ambient range and supporting 1500 VRMS working voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577, VDE 60747-17, CSA 62368-1) |
| Channel-to-Channel Skew | <5 ns - ensures synchronized switching in half-bridge topologies to prevent shoot-through |
| CMTI | >200 kV/µs - maintains signal integrity in high-dV/dt SiC/GaN environments |
| Peak Output Current | 6 A sourcing/sinking - directly drives high-gate-charge SiC FETs without external buffers |
| Logic Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller interfaces |
| Gate Supply Range | 5–30 V - supports 12 V and 15 V gate bias for optimal Rds(on) and switching loss trade-offs |
| Operating Temperature | –40 to +125 °C - qualified for automotive under-hood and industrial motor drive environments |
| UVLO Thresholds | Configurable at 4 V, 8 V, 12 V, or 15 V - prevents erratic switching during brown-out conditions |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage-optimized layout for reinforced insulation. Pinout matches Si82E39x Universal configuration with Enable (EN) input.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for Channel A | Directly controls VOA output state; high noise immunity via Schmitt trigger and deglitch filter |
| VIB | Non-inverting logic input for Channel B | Directly controls VOB output state; independent of VIA for dual-drive operation |
| EN | Active-high enable control | Asserting EN = high enables normal operation; deasserting forces VOA/VOB low unconditionally |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~18–200 ns); tied to VDDI disables dead time |
| VDDI | Logic input supply | 3–20 V rail powering internal digital circuitry and isolation modulator |
| GNDI | Logic input ground | Reference for all digital inputs; galvanically isolated from GNDA/GNDB |
| VDDA / GNDA | Channel A gate driver supply/ground | 5–30 V isolated supply for high-side or low-side output stage; includes UVLO and clamp |
| VDDB / GNDB | Channel B gate driver supply/ground | Independent 5–30 V supply with per-channel UVLO, thermal shutdown, and shutdown clamp |
| VOA / VOB | Isolated gate driver outputs | Voltage-mode outputs with 6 A peak drive; short-circuit clamped to VDDA/B |
| NC | No connection | Pins 12, 13, and 16 are unconnected die pads - must remain floating |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Mode Drive | Output current controlled by external gate resistors - enables precise tuning of dV/dt, EMI, and overshoot without changing IC design |
| Programmable Dead Time | Adjustable 18–200 ns via single resistor on DT pin - eliminates need for external logic or MCU-based dead-time insertion |
| Overlap Protection | Hardware-enforced immediate low-state on both outputs if VIA and VIB go high simultaneously - prevents shoot-through even with controller timing errors |
| Shutdown Clamp | Active pull-down on VOA/VOB when VDDA/B is unpowered - blocks parasitic turn-on of MOSFETs/IGBTs during power sequencing |
| AEC-Q100 Grade | Qualified for automotive applications (Grade 1: –40 to +125 °C) with zero-defect manufacturing flow - suitable for OBC and traction inverter designs |
| 10 kV Bipolar Surge | Withstands ±10 kV surge per IEC 61000-4-5 - enhances reliability in noisy industrial and EV charging environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated dual-channel gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SIL1225CD-IM | Single-channel, 4 A output; 5 kVRMS isolation; no dead-time programming pin | Lacks dual-channel integration and hardware overlap protection - requires two devices and external logic for half-bridge | Select only when space and cost constraints permit discrete channel implementation and dead time is managed externally |
| UCC5390SCD | 6 A dual-channel; 5.7 kVRMS; 100 kV/µs CMTI; no AEC-Q100 qualification; different pinout (SOIC-16 WB) | Lower CMTI and no automotive qualification - unsuitable for OBC or traction inverter use cases requiring 200 kV/µs immunity | Consider for industrial UPS where AEC-Q100 and maximum CMTI are not mandated |
Compared with SIL1225CD-IM and UCC5390SCD, SI82E39ABC-IS1R delivers higher integration (dual-channel + EN + DT in one SOIC-16), superior noise immunity (200 kV/µs vs. ≤100 kV/µs), and automotive-grade reliability - making it optimal for safety-critical, high-density SiC/GaN power stages.

FAQ
What is the isolation voltage rating of the SI82E39ABC-IS1R?
The SI82E39ABC-IS1R is safety-certified for 6 kVRMS isolation for one minute per UL 1577, VDE 60747-17, and CSA 62368-1 standards. It supports a continuous working voltage of 1500 VRMS and withstands ±10 kV bipolar surge per IEC 61000-4-5. This reinforced insulation rating makes SI82E39ABC-IS1R suitable for high-voltage EV and industrial applications where creepage and clearance compliance are critical.
Does the SI82E39ABC-IS1R support both high-side/low-side and dual independent configurations?
Yes, the SI82E39ABC-IS1R uses the Universal pinout configuration with VIA/VIB inputs and EN/DT control, enabling both modes. When DT is grounded, it operates as a high-side/low-side driver with programmable dead time and overlap protection. When DT is tied to VDDI, dead time and overlap protection are disabled, allowing independent control of VOA and VOB - effectively functioning as two isolated single-channel drivers.
What UVLO thresholds are available on the SI82E39ABC-IS1R?
The SI82E39ABC-IS1R offers factory-configured UVLO thresholds on VDDI, VDDA, and VDDB rails at 4 V, 8 V, 12 V, or 15 V. These thresholds are fixed per device variant and selected at order time - they cannot be adjusted externally. The UVLO hysteresis ensures clean entry/exit behavior during power-up and brown-out events, preventing erratic gate drive during unstable supply conditions.
How does the SI82E39ABC-IS1R handle thermal faults?
The SI82E39ABC-IS1R integrates independent thermal sensors per channel. If junction temperature exceeds the trigger threshold (TSD+), the affected channel enters thermal shutdown and pulls VOA or VOB low. After 1 ms, if temperature remains above the reset threshold (TSD–), the output transitions to a weak low state until temperature falls below TSD–. This dual-threshold hysteresis prevents oscillation and enables safe recovery without system reset.
Can the SI82E39ABC-IS1R drive SiC and GaN FETs directly?
Yes, the SI82E39ABC-IS1R delivers 6 A peak sourcing and sinking current with fast rise/fall times (<25 ns typical), making it capable of directly driving medium-power SiC MOSFETs (e.g., up to 1200 V/40 mΩ) and GaN HEMTs without external buffers. Its voltage-mode architecture and external gate resistors allow designers to optimize switching speed, EMI, and gate overshoot independently for each FET technology.
