Product details
Overview
SI82F39BBC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver in narrow-body 16-pin SOIC package, configured for universal (independent high-side/low-side) operation with enable (EN) input. It delivers ±1.5 A peak sourcing/sinking current via SelVCD™, supports 3–20 V logic supply and 5–30 V gate supply, and targets SiC/GaN FETs in half-bridge motor inverters and onboard chargers.
For engineers reviewing the SI82F39BBC-IS1R datasheet, SI82F39BBC-IS1R pinout, SI82F39BBC-IS1R application, or SI82F39BBC-IS1R equivalent, key selection criteria include channel-to-channel skew < 5 ns, CMTI > 200 kV/µs, integrated Miller clamp, programmable dead time, and AEC-Q100 qualification for automotive powertrain systems.
Technical Context
The SI82F39BBC-IS1R implements dual CMOS-isolated channels using silicon-dioxide capacitive isolation, enabling 6 kVRMS reinforced insulation and 1500 VRMS working voltage. Its functional architecture includes independent VIA/VIB inputs, EN-controlled enable logic, SPD± analog programming for eight-level current drive, and DT-resistor-programmable dead time.
It operates as a current-source output stage with ±10% current regulation over temperature and process for UVLO = 8 V/12 V/15 V variants, and integrates shutdown clamps that force VOA/VOB low during UVLO, DIS assertion, or unpowered VDDA/VDDB - ensuring no undefined output states under fault conditions.
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 - enables precise timing alignment between high-side and low-side gate signals in half-bridge topologies |
| CMTI | > 200 kV/µs - ensures robust noise immunity in high-dV/dt environments like SiC/GaN switching |
| Output Current | ±1.5 A peak (SPD7 level) - sufficient to drive 1200 V SiC MOSFETs with fast turn-on/turn-off without external gate resistors |
| UVLO Threshold | 12 V (typical) - provides stable gate drive only when gate supply exceeds safe minimum for full enhancement of wide-bandgap devices |
| Operating Temp | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications |
| Package | Narrow-body 16-pin SOIC - 10.3 mm × 10.3 mm footprint compatible with standard PCB assembly and thermal relief design |
Pinout & Package
Narrow-body 16-pin SOIC (NB SOIC-16) package with 1.27 mm pitch, creepage ≥ 8.0 mm, and reinforced insulation barrier between input and output sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for channel A | Directly controls VOA state; CMOS-compatible with deglitch filter option for noise immunity |
| VIB | Non-inverting logic input for channel B | Directly controls VOB state; independent of VIA, enabling universal dual-driver configuration |
| EN | Active-high enable input | Unconditionally forces VOA/VOB low when deasserted; enables fail-safe shutdown in system control logic |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → 18–200 ns); tied to VDDI disables dead time for dual-driver mode |
| SPD+ | Sourcing current programming input | Resistor-to-GND selects one of eight sourcing current levels (0.25–1.5 A); eliminates need for external turn-on gate resistors |
| SPD− | Sinking current programming input | Resistor-to-GND selects one of eight sinking current levels (0.25–1.5 A); enables integrated Miller clamp activation during turn-off |
| VOA / VOB | Gate driver outputs | Current-source outputs with built-in Miller clamp; directly connect to power device gates without series resistors |
| VDDI / GNDI | Logic input supply | 3–20 V tolerant; powers isolated input side and enables robust interfacing with MCU/FPGA I/O |
| VDDA / GNDA / VDDB / GNDB | Independent gate driver supplies | 5–30 V per channel; allows asymmetric rail configurations and independent UVLO monitoring per output |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight programmable sourcing/sinking current levels (0.25–1.5 A) via SPD± pins - replaces discrete gate resistors and enables dynamic speed tuning |
| Integrated Miller Clamp | Automatically engages when VOA/VOB falls below VMCTA/B (~2 V) - suppresses Miller-induced false turn-on in SiC/GaN FETs without external components |
| Programmable Dead Time | Resistor-set dead time (18–200 ns) with overlap protection - prevents shoot-through in half-bridge configurations without external logic |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C) qualification across manufacturing flow - ensures reliability for automotive traction inverters and OBCs |
| No Unknown Output States | Defined VOA/VOB = low during UVLO, EN = low, DIS = high, or unpowered VDDA/VDDB - eliminates risk of unintended power device conduction |

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 |
|---|---|---|---|
| Si8239BB-IM1R | Same Si82Fx family, wide-body 14-pin SOIC package; identical electrical specs but different pinout and creepage (≥10.2 mm) | Better suited for designs requiring higher creepage/clearance or space-constrained layouts where WB SOIC-14 fits better than NB SOIC-16 | Select Si8239BB-IM1R if board layout requires wider creepage or narrower package width (8.7 mm vs. 10.3 mm) |
| UCC5390SCD | Texas Instruments part with 5.7 kVRMS isolation, 1.5 A drive, but uses transformer-based isolation and lacks SelVCD™ current programming | Requires external gate resistors and separate Miller clamp circuitry; not AEC-Q100 qualified | Choose UCC5390SCD only for cost-sensitive industrial applications where automotive qualification and resistorless design are not required |
Compared with SI82F39BBC-IS1R, Si8239BB-IM1R offers identical performance in a mechanically distinct package, while UCC5390SCD provides baseline isolation and drive capability but lacks programmable current control, integrated Miller clamp, and automotive qualification - making SI82F39BBC-IS1R the preferred choice for high-reliability SiC/GaN systems.

FAQ
What is the isolation rating of the SI82F39BBC-IS1R and which safety standards does it meet?
The SI82F39BBC-IS1R provides 6 kVRMS isolation for 1 minute and 1500 VRMS working voltage. It is certified to UL 1577 (reinforced), VDE 60747-17 (reinforced), CSA 62368-1 (reinforced), and CSA 60601-1 (2 MOPP). These approvals confirm its suitability for medical, industrial, and automotive applications requiring reinforced insulation barriers between control and power domains.
Does the SI82F39BBC-IS1R support both high-side/low-side and dual independent configurations?
Yes, the SI82F39BBC-IS1R is a Universal-configuration device with VIA and VIB inputs, allowing it to operate either as independent high-side/low-side drivers or as two fully decoupled gate drivers. Connecting the DT pin to VDDI disables dead time and overlap protection, enabling pure dual-driver mode - confirmed in the Si82F39x functional block diagram and truth table.
How does the SelVCD™ technology in the SI82F39BBC-IS1R eliminate the need for external gate resistors?
SelVCD™ configures the SI82F39BBC-IS1R's outputs as precision current sources with eight selectable levels (0.25–1.5 A). Because output current is actively regulated - not voltage-limited - gate charging/discharging is controlled by current magnitude and duration, not RC time constants. This removes dependency on external resistors while enabling the integrated Miller clamp to function directly at VOA/VOB pins.
What is the purpose of the SPD+ and SPD− pins on the SI82F39BBC-IS1R?
The SPD+ and SPD− pins on the SI82F39BBC-IS1R set the sourcing and sinking current levels for both VOA and VOB outputs. Each pin accepts a resistor-to-GND to select one of eight discrete current values (e.g., 1.5 A at SPD7). This allows fine-grained optimization of switching speed, EMI, and Miller immunity - all without modifying the PCB layout or adding discrete components.
Is the SI82F39BBC-IS1R qualified for automotive applications?
Yes, the SI82F39BBC-IS1R is AEC-Q100 qualified Grade 1 (–40 °C to +125 °C) and manufactured using automotive-specific process flows. It supports automotive use cases including traction inverters, onboard chargers, and DC-DC converters, with full documentation of HTOL, TC, and ESD (4 kV HBM) test results in the preliminary datasheet.
