Product details
Overview
SI82E39AEC-IS1 from Skyworks Solutions is a dual-channel isolated gate driver with 6 A peak output current, universal configuration (independent VIA/VIB inputs), and enable (EN) control logic. It delivers <5 ns channel-to-channel skew, 200 kV/µs CMTI, and 6 kVRMS reinforced isolation for driving SiC/GaN FETs in half-bridge topologies. Used in onboard chargers and motor drives requiring precise timing and high noise immunity.
For engineers reviewing the SI82E39AEC-IS1 datasheet, SI82E39AEC-IS1 pinout, SI82E39AEC-IS1 application, or SI82E39AEC-IS1 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, automotive-grade reliability data, and two confirmed alternative parts with documented functional differences.
Technical Context
The SI82E39AEC-IS1 implements capacitive silicon-dioxide isolation with differential RF-modulated OOK signaling, enabling robust fault tolerance and sub-5 ns skew between channels. Its universal input architecture accepts independent non-inverting logic signals (VIA, VIB) and supports programmable dead time via external resistor on DT pin.
It features voltage-mode drive with CMOS-compatible inputs, integrated UVLO thresholds (4/8/12/15 V options), shutdown clamp for unpowered operation, and thermal shutdown at 150 °C. The device operates across –40 to 125 °C and is AEC-Q100 qualified for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for 1 minute - meets UL 1577, VDE 60747-17, and CSA 62368-1 reinforced insulation requirements. |
| Channel-to-Channel Skew | <5 ns - ensures synchronized switching in high-frequency half-bridge circuits without shoot-through risk. |
| CMTI | >200 kV/µs - prevents false triggering in noisy power converter environments with fast dV/dt transients. |
| Peak Output Current | 6 A sourcing/sinking - directly drives high-gate-charge SiC and GaN FETs without external buffers. |
| Input Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller logic without level-shifting. |
| Gate Supply Range | 5–30 V - supports wide-range biasing for both low-side and bootstrap-powered high-side gate drivers. |
| Operating Temperature | –40 to 125 °C - validated for under-hood automotive and industrial motor drive applications. |
| UVLO Thresholds | Configurable at 4 V, 8 V, 12 V, or 15 V - prevents erratic switching during brown-out or startup conditions. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage-optimized layout for reinforced isolation. Pin 1 marked; pins 12 and 13 are NC (no connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting input for Channel A | Accepts CMOS-level PWM or logic signal; enables independent control of high-side or low-side FET in universal mode. |
| VIB | Non-inverting input for Channel B | Independent logic input for second channel; allows asymmetric drive or phase-shifted operation. |
| EN | Active-high enable | Pulls both outputs low when deasserted; used for system-level fault shutdown with tDID/tEID timing control. |
| DT | Dead time programming | Resistor-to-GND sets dead time (10–110 kΩ → ~18–200 ns); tied to VDDI disables dead time for dual-driver mode. |
| VDDA / GNDA | Channel A gate supply and ground | Isolated 5–30 V power domain for high-side or low-side driver A; supports bootstrap or isolated supply. |
| VDDB / GNDB | Channel B gate supply and ground | Independent isolated 5–30 V domain for driver B; enables split-bias or shared-rail configurations. |
| VDDI / GNDI | Logic input supply and ground | 3–20 V digital interface side; galvanically separated from gate drive domains by SiO₂ capacitors. |
| VOA / VOB | Gate driver outputs | Voltage-mode outputs with 6 A peak capability; include short-circuit clamp and shutdown clamp for safe FET turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Universal input configuration | Independent VIA/VIB logic inputs - supports asymmetrical drive, phase-shifted converters, and non-complementary topologies. |
| Voltage-mode gate drive | No external current-sense feedback needed - simplifies layout and enables predictable rise/fall times via gate resistors Rg. |
| Programmable dead time | Adjustable 18–200 ns via single external resistor - eliminates need for controller-side dead-time insertion logic. |
| Integrated shutdown clamp | Active pull-down when VDDA/B is unpowered - prevents parasitic turn-on of MOSFETs/IGBTs during power sequencing. |
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures up to 125 °C - suitable for traction inverters and OBCs without derating. |
| 1500 VRMS working voltage | Rated for continuous operation in 800 V DC bus systems - meets reinforced insulation requirements per IEC 60747-17. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs SI8239AD-IS1 | Same Si82Ex family, but with disable (DIS) instead of enable (EN) logic; identical pinout and specs otherwise. | Requires active-low fault signaling path; less intuitive for systems using positive-logic enable trees. | Select SI82E39AEC-IS1 when controller outputs active-high enable signals; choose SI8239AD-IS1 only if DIS logic matches existing PCB routing. |
| TI UCC5390SCD | Lower 4 A peak output, no programmable dead time, fixed 5 V logic supply only, and 5 kVRMS isolation rating. | Limited to lower-power 650 V Si MOSFETs; not rated for 800 V SiC/GaN systems or automotive temperature range. | Use UCC5390SCD only in cost-sensitive, non-automotive 400 V applications where dead time is managed externally and CMTI >150 kV/µs is not required. |
Compared with SI8239AD-IS1, SI82E39AEC-IS1 offers more intuitive system-level fault handling via EN; compared with UCC5390SCD, it delivers higher drive strength, wider supply flexibility, and certified 6 kVRMS isolation essential for 800 V EV and industrial systems.

FAQ
What is the isolation rating of the SI82E39AEC-IS1 and which safety standards does it meet?
The SI82E39AEC-IS1 provides 6 kVRMS isolation for one minute and 1500 VRMS working voltage. It is UL 1577 recognized, VDE 60747-17 certified for reinforced insulation, CSA 62368-1 and 60601-1 compliant (2 MOPP), and CQC GB4943.1 approved. These certifications validate its use in medical, industrial, and automotive safety-critical systems where galvanic separation is mandatory.
Does the SI82E39AEC-IS1 support both high-side/low-side and dual independent configurations?
Yes, the SI82E39AEC-IS1 is a universal-configuration device with independent VIA and VIB inputs. When the DT pin is connected to VDDI, dead time and overlap protection are disabled, allowing true dual independent operation. When DT is resistor-connected to GNDI, it functions as a high-side/low-side driver with programmable dead time - making SI82E39AEC-IS1 adaptable to multiple topologies without hardware change.
What is the purpose of the EN pin on the SI82E39AEC-IS1 and how does it behave during fault conditions?
The EN pin on SI82E39AEC-IS1 is an active-high enable that unconditionally forces both VOA and VOB low when deasserted (logic low). It responds within tDID (typ. 25 ns) after falling below VIH and resumes normal operation within tEID (typ. 45 ns) after rising above VIH. This makes SI82E39AEC-IS1 ideal for fast system-level fault shutdown - such as overcurrent or overtemperature events - without relying on controller firmware latency.
Can the SI82E39AEC-IS1 drive SiC and GaN FETs directly, and what gate resistor guidance applies?
Yes, the SI82E39AEC-IS1 delivers 6 A peak sourcing/sinking current and supports 5–30 V gate supplies - sufficient to directly drive common 10–100 nC SiC and GaN FETs. Gate resistor selection must balance switching speed, overshoot, and EMI: lower Rg increases di/dt (risking oscillation), while higher Rg slows transitions (increasing conduction loss). Recommended starting values are 2.2–10 Ω for 1200 V SiC and 1–4.7 Ω for 650 V GaN, adjusted per FET datasheet Qg and layout parasitics.
How does the SI82E39AEC-IS1 handle undervoltage lockout (UVLO) for its different power domains?
The SI82E39AEC-IS1 implements independent UVLO on VDDI (logic supply), VDDA (driver A), and VDDB (driver B). VDDI UVLO thresholds are fixed at 4/8/12/15 V depending on variant; VDDA/B UVLO triggers at ~4.5 V (falling) and ~5.5 V (rising). If VDDI is in UVLO, all outputs are forced low regardless of VDDA/B state. If only VDDA is in UVLO, VOA remains low while VOB continues normal operation - enabling graceful partial-fault operation in multi-rail systems.
