Product details
Overview
SI82E39BGC-IS1 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 power converters and motor drives. It features 6 kVRMS reinforced isolation, <5 ns channel-to-channel skew, 200 kV/µs CMTI, and operates with 3–20 V logic supply and 5–30 V gate supply - enabling robust SiC and GaN FET switching in onboard chargers and industrial inverters.
For engineers reviewing the SI82E39BGC-IS1 datasheet, SI82E39BGC-IS1 pinout, SI82E39BGC-IS1 application, or SI82E39BGC-IS1 equivalent, key selection considerations include its EN-controlled universal configuration, programmable dead time via DT pin, UVLO thresholds (4/8/12/15 V options), and narrow-body SOIC-16 automotive-grade packaging with AEC-Q100 qualification.
Technical Context
The SI82E39BGC-IS1 implements capacitive silicon-dioxide (SiO₂) isolation with differential RF-modulated OOK signaling, delivering precise timing fidelity and fault tolerance between input and output domains. Its dual-channel architecture supports independent non-inverting inputs (VIA/VIB) and an active-high ENABLE (EN) signal that forces both outputs low when deasserted.
It integrates voltage-mode drive with external gate resistor tuning, programmable dead time (via resistor to GNDI), undervoltage lockout per supply domain (VDDI, VDDA, VDDB), and shutdown clamps to prevent parasitic turn-on during unpowered conditions - all within a single 16-pin narrow-body SOIC package rated for –40 °C to +125 °C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 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 precise synchronous switching in half-bridge topologies, minimizing shoot-through risk. |
| CMTI | >200 kV/µs - maintains signal integrity in high-dV/dt environments like SiC/GaN-based inverters. |
| Peak Output Current | 6 A sourcing/sinking - directly drives high-gate-charge power devices without external buffers. |
| Logic Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller interfaces without level-shifting. |
| Gate Supply Range | 5–30 V - supports bipolar gate biasing and wide-range MOSFET/IGBT/SiC FET drive voltages. |
| Operating Temperature | –40 °C to +125 °C - qualified for automotive under-hood and industrial power-conversion applications. |
Pinout & Package
Narrow-body 16-pin SOIC (NB SOIC-16) package with creepage ≥8.3 mm and clearance ≥8.0 mm - optimized for high-voltage isolation and automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for Channel A | Directly controls VOA output state; CMOS-compatible with deglitch filter option. |
| VIB | Non-inverting logic input for Channel B | Directly controls VOB output state; enables independent dual-drive or complementary half-bridge operation. |
| EN | Active-high enable input | When low, forces VOA and VOB logic low unconditionally - critical for fast system fault response. |
| DT | Dead time programming input | Resistor-to-GNDI sets dead time (10–110 kΩ → ~19–210 ns); tied to VDDI disables dead time for universal mode. |
| VDDA / GNDA | Channel A gate driver supply and ground | Independent 5–30 V power domain for high-side or low-side output stage; includes dedicated UVLO. |
| VDDB / GNDB | Channel B gate driver supply and ground | Independent 5–30 V power domain with separate UVLO - enables asymmetric bootstrap or isolated supplies. |
| VDDI / GNDI | Logic input supply and ground | 3–20 V domain powering isolation barrier and digital interface; UVLO threshold configurable per device variant. |
| VOA / VOB | Gate driver A and B outputs | Voltage-mode outputs with 6 A peak drive; include short-circuit clamp and shutdown clamp for safe FET control. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Dead Time | Resistor-adjustable (10–110 kΩ) with overlap protection - prevents shoot-through in half-bridge configurations without external logic. |
| Voltage-Mode Drive | External gate resistors (Rg) set switching speed, overshoot, and EMI - eliminates need for current-source gate drivers. |
| Multi-Threshold UVLO | Configurable 4 V / 8 V / 12 V / 15 V logic and gate supply UVLO - ensures reliable startup/shutdown across diverse power architectures. |
| Automotive Qualification | AEC-Q100 Grade 1 (–40 °C to +125 °C) with automotive-specific manufacturing flow - validated for EV traction inverters and OBCs. |
| Robust ESD Protection | 4 kV HBM on all pins - withstands handling and board-level transients without latch-up or degradation. |

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-IS1 | Single-channel, 4 A output, 5 kVRMS isolation, no dead time control | Limited to single-leg or paralleled use; lacks half-bridge coordination features | Select when only one isolated channel is needed and cost sensitivity outweighs integration benefits |
| UCC5390SCD | TI part with 10 A peak drive, integrated Miller clamp, but only 3.75 kVRMS isolation and no AEC-Q100 grade | Higher drive strength but lower isolation rating; not certified for automotive systems | Prefer for industrial servo drives where higher current matters more than reinforced insulation or automotive qualification |
Compared with SIL1225CD-IS1 and UCC5390SCD, SI82E39BGC-IS1 uniquely combines AEC-Q100 qualification, 6 kVRMS reinforced isolation, <5 ns skew, and EN-controlled dual-channel operation in a single NB SOIC-16 package - making it optimal for space-constrained, safety-critical automotive and industrial power modules.

FAQ
What is the isolation voltage rating of the SI82E39BGC-IS1?
The SI82E39BGC-IS1 provides 6 kVRMS isolation for one minute, certified to UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1 standards. This reinforced insulation rating supports 1500 VRMS working voltage and enables safe operation in 1000 V-class power systems such as EV onboard chargers and industrial inverters.
Does the SI82E39BGC-IS1 support both high-side/low-side and dual independent configurations?
Yes, the SI82E39BGC-IS1 supports both modes. When the DT pin is connected to GNDI via a resistor, it operates as a high-side/low-side driver with programmable dead time. When DT is tied to VDDI, dead time and overlap protection are disabled, allowing VIA and VIB to independently control VOA and VOB - ideal for dual-switch topologies like synchronous buck or phase-shifted full-bridge.
What UVLO thresholds are implemented in the SI82E39BGC-IS1?
The SI82E39BGC-IS1 features factory-configured UVLO thresholds: 4 V, 8 V, 12 V, and 15 V options for VDDI, VDDA, and VDDB supplies. These thresholds prevent erroneous switching during brown-out conditions and ensure clean startup/shutdown sequencing - critical for SiC FET gate integrity in high-frequency power converters.
How does the EN pin function in the SI82E39BGC-IS1?
The EN pin on the SI82E39BGC-IS1 is an active-high enable signal. When pulled low, it unconditionally forces both VOA and VOB outputs to logic low within tDID (typ. 25 ns), regardless of input states or supply conditions. This enables rapid system-level fault shutdown - essential for overcurrent protection in motor drives and inverters.
Is the SI82E39BGC-IS1 qualified for automotive applications?
Yes, the SI82E39BGC-IS1 is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C) and manufactured using automotive-specific process flows. It meets stringent defectivity and robustness requirements for EV traction inverters, onboard chargers, and DC-DC converters - with full documentation of HTOL, TC, and ESD validation per AEC-Q100 Rev H.
