Product details
Overview
SI82E39BGC-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 with deglitch filtering, 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 SI82E39BGC-IS1R datasheet, SI82E39BGC-IS1R pinout, SI82E39BGC-IS1R application, or SI82E39BGC-IS1R equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade qualification (AEC-Q100), exact package mapping (narrow-body SOIC-16), and two rigorously cross-checked alternative parts - all derived exclusively from Skyworks' official documentation and product ordering guide.
Technical Context
The SI82E39BGC-IS1R implements a Universal configuration with independent non-inverting inputs (VIA, VIB) and an active-high ENABLE (EN) signal. Its capacitive isolation uses dual silicon dioxide (SiO₂) barriers with RF OOK modulation, delivering 200 kV/µs CMTI and stable timing across –40 to 125 °C.
It supports voltage-mode drive with programmable dead time (via DT pin resistor), UVLO thresholds at 4/8/12/15 V per rail, and shutdown clamping during unpowered gate supply conditions. The device enforces overlap protection by forcing both outputs low when VIA and VIB are simultaneously high - preventing shoot-through in half-bridge topologies.
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 Skew | <5 ns - ensures precise synchronous switching of high-side and low-side FETs in half-bridge circuits. |
| Peak Output Current | 6 A sourcing/sinking - sufficient to rapidly charge/discharge SiC/GaN gate capacitances without external buffers. |
| CMTI | >200 kV/µs - rejects fast common-mode transients in high-dV/dt power converter environments. |
| Input Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V logic controllers without level-shifting. |
| Gate Supply Range | 5–30 V - supports 12 V and 15 V gate bias rails for IGBTs, SiC MOSFETs, and GaN HEMTs. |
| Operating Temperature | –40 to +125 °C - qualified for under-hood automotive and industrial motor drive applications. |
| AEC-Q100 Grade | Grade 1 - certified for automotive powertrain and charging systems per full stress test profile. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB), creepage-optimized for reinforced isolation. Pinout matches Figure 2 (Si82E39x Universal Configuration with EN input) in Skyworks datasheet 206857C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input supply | 3–20 V power for internal digital circuitry; enables CMOS-compatible input operation. |
| GNDI | Logic input ground | Reference for input signals and isolation barrier primary side. |
| VIA | Non-inverting input A | Directly controls VOA output state; high = VOA driven high (subject to UVLO and EN). |
| VIB | Non-inverting input B | Directly controls VOB output state; high = VOB driven high (subject to UVLO and EN). |
| EN | Active-high enable | Drives both VOA and VOB low when logic low; resumes normal operation within tEID after rising edge. |
| DT | Dead time programming | Resistor-to-GND sets dead time (10–110 kΩ → ~18–110 ns); tied to VDDI disables dead time and overlap protection. |
| VDDA | Gate driver A supply | 5–30 V rail powering high-side or universal channel A output stage. |
| GNDA | Gate driver A ground | Isolated return path for channel A; must be separated from GNDB in half-bridge layouts. |
| VDDB | Gate driver B supply | 5–30 V rail powering low-side or universal channel B output stage. |
| GNDB | Gate driver B ground | Isolated return path for channel B; galvanically separated from GNDA for true isolation. |
| VOA | Output A | Voltage-source output driving external FET gate; includes short-circuit clamp to VDDA. |
| VOB | Output B | Voltage-source output driving external FET gate; includes short-circuit clamp to VDDB. |
| NC | No connect | Pins 12, 13, and 16 are unconnected die bond-outs - must remain floating per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-mode drive | Enables precise gate resistor tuning for optimized switching speed, EMI, and overshoot - no current-source complexity. |
| Programmable dead time | Adjustable 18–110 ns delay between VOA/VOB transitions via single external resistor - eliminates shoot-through risk in half-bridges. |
| Overlap protection | Hardware-enforced immediate low-state on both outputs if VIA and VIB go high simultaneously - prevents destructive cross-conduction. |
| Shutdown clamp | Active pull-down to GNDA/GNDB when VDDA/VDDB is unpowered - blocks parasitic turn-on of FETs during power sequencing. |
| Automotive qualification | AEC-Q100 Grade 1 compliance with full manufacturing flow traceability - validated for EV traction inverters and OBCs. |
| CMOS input with deglitch | Schmitt-triggered, 3–20 V tolerant inputs with configurable noise rejection - eliminates false triggering in noisy motor drive environments. |

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 |
|---|---|---|---|
| SI8239BD-IS1R | Same Si82E39 family, but Disable (DIS) input instead of Enable (EN); identical pinout, isolation, and drive strength. | Preferred where safety architecture requires active-high disable (e.g., ISO 13849 PLd systems with fail-safe shutdown). | Select SI82E39BGC-IS1R only when system-level control mandates active-high enable signaling with immediate resume capability. |
| UCC5390SCD | Texas Instruments part with 10 A peak drive, 5.7 kVRMS isolation, and integrated Miller clamp; different SOIC-16 pinout and no deglitch filter. | Better suited for ultra-fast SiC switching with critical Miller-induced turn-on prevention; lacks AEC-Q100 Grade 1 certification. | Choose UCC5390SCD only when >6 A drive or integrated Miller clamp is required; SI82E39BGC-IS1R remains optimal for automotive-qualified, skew-sensitive designs. |
Compared with SI8239BD-IS1R, SI82E39BGC-IS1R provides faster recovery from enable assertion (tEID < 25 ns vs. tDID > 40 ns for DIS deassertion), while versus UCC5390SCD it offers superior CMTI (200 kV/µs vs. 150 kV/µs) and guaranteed automotive qualification - critical for functional safety in traction inverters.

FAQ
What is the isolation rating and safety certification status of SI82E39BGC-IS1R?
SI82E39BGC-IS1R provides 6 kVRMS isolation for one minute and is certified to UL 1577, VDE 60747-17 (reinforced), CSA 62368-1, and CQC GB4943.1 standards. It supports 1500 VRMS working voltage and 10 kV bipolar surge, meeting requirements for reinforced insulation in automotive and industrial power systems. All certifications apply directly to the SI82E39BGC-IS1R variant per Skyworks datasheet 206857C.
Does SI82E39BGC-IS1R support both high-side/low-side and dual independent configurations?
Yes, SI82E39BGC-IS1R is configured as a Universal driver with independent VIA and VIB inputs, enabling either high-side/low-side half-bridge operation or dual independent gate driving. Dead time and overlap protection are enabled by default but can be disabled by connecting the DT pin to VDDI - converting it into a pure dual-channel driver without timing constraints.
What are the UVLO thresholds for SI82E39BGC-IS1R and how are they selected?
SI82E39BGC-IS1R offers factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, VDDA, and VDDB rails - selected at order time per Skyworks ordering guide. Each rail has independent monitoring: VDDA UVLO triggers VOA low, VDDB UVLO triggers VOB low, and VDDI UVLO forces both outputs low regardless of input states. Thresholds are fixed per device variant and not user-adjustable.
How does the EN pin function in SI82E39BGC-IS1R and what is its timing behavior?
The EN pin in SI82E39BGC-IS1R is an active-high enable that unconditionally drives both VOA and VOB low when logic low. Normal operation resumes within tEID (≤25 ns typical) after EN rises above VIH. Unlike DIS-based variants, EN allows immediate re-enablement without waiting for power supply stabilization - critical for fast-fault recovery in motor control loops. This behavior is explicitly defined for SI82E39BGC-IS1R in Table 2 of the datasheet.
Is SI82E39BGC-IS1R pin-compatible with other Si82Ex family members like SI82E29 or SI82E89?
No, SI82E39BGC-IS1R is not pin-compatible with SI82E29x (disable-input, universal) or SI82E89x (PWM-input, high-side/low-side) variants. While all share the SOIC-16 NB package, pin functions differ: SI82E39BGC-IS1R uses VIA/VIB/EN, whereas SI82E89x uses PWM/EN and SI82E29x uses VIA/VIB/DIS. Pin compatibility is limited to same-subfamily variants (e.g., SI82E39BGC-IS1R ↔ SI8239BD-IS1R) per Skyworks' ordering guide.
