Product details
Overview
SI82F39AEE-IS3 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 ±4 A peak sourcing/sinking current via SelVCD™ across eight programmable levels, supports 3–20 V logic supply and 5–30 V gate supply, and provides 6 kVRMS reinforced isolation for driving SiC/GaN FETs in half-bridge motor inverters.
For engineers reviewing the SI82F39AEE-IS3 datasheet, SI82F39AEE-IS3 pinout, SI82F39AEE-IS3 application, or SI82F39AEE-IS3 equivalent, key selection criteria include channel-to-channel skew < 5 ns, integrated Miller clamp, dead time programmability via external resistor, CMTI > 200 kV/μs, and AEC-Q100 qualification for automotive powertrain systems.
Technical Context
The SI82F39AEE-IS3 implements dual CMOS-isolated channels using differential RF-modulated capacitive coupling across silicon dioxide barriers, enabling 6 kVRMS isolation and 1500 VRMS working voltage. Its digital inputs (VIA, VIB, EN) are Schmitt-triggered with deglitch filtering, and analog speed control (SPD+, SPD−) sets sourcing/sinking current independently via resistor-divided voltage thresholds.
It operates in universal configuration: VOA follows VIA and VOB follows VIB, with DT pin configurable to insert programmable dead time (via RDT) or disable overlap protection when tied to VDDI. UVLO thresholds are factory-set at 12 V per channel, and outputs remain low during any supply undervoltage condition.
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 Skew | < 5 ns - ensures precise timing alignment between VOA and VOB transitions in high-frequency switching. |
| Output Current | ±4 A peak (SPD7 level) - eliminates need for external gate resistors and enables direct drive of high-Qg SiC/GaN FETs. |
| CMTI | > 200 kV/μs - prevents false triggering in noisy high-dV/dt environments like motor drives and inverters. |
| Logic Supply Range | 3 V to 20 V - compatible with 3.3 V, 5 V, and 15 V controller interfaces without level-shifting. |
| Gate Supply Range | 5 V to 30 V - supports wide-range biasing for IGBTs, MOSFETs, and wide-bandgap devices. |
| UVLO Threshold | 12 V (VDDA/B) - ensures stable turn-on only after gate supply reaches safe operating margin. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions. |
Pinout & Package
Narrow-body 16-pin SOIC (NB SOIC-16) package with 1.27 mm pitch and creepage ≥ 8.3 mm. Pin 1 marked by dot; pins 12 and 13 are NC (no connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for channel A | Directly controls VOA state; high = VOA high, low = VOA low (subject to EN/UVLO). |
| VIB | Non-inverting logic input for channel B | Directly controls VOB state; high = VOB high, low = VOB low (subject to EN/UVLO). |
| EN | Active-high enable input | Drives both VOA and VOB low when logic low; device resumes normal operation within tEID after rising edge. |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~10–120 ns); tie to VDDI to disable dead time and overlap protection. |
| SPD+ | Sourcing current control input | Resistor-to-GND selects one of eight sourcing current levels (SPD1–SPD7); determines VOA/VOB turn-on strength. |
| SPD− | Sinking current control input | Resistor-to-GND selects one of eight sinking current levels (SPD1–SPD7); determines VOA/VOB turn-off strength. |
| VDDA / GNDA | Channel A gate driver supply and ground | Independent 5–30 V bias for high-side or low-side output stage; includes dedicated UVLO monitoring. |
| VDDB / GNDB | Channel B gate driver supply and ground | Independent 5–30 V bias for second output stage; UVLO operates independently of VDDA. |
| VDDI / GNDI | Logic input supply and ground | 3–20 V supply for isolated input side; UVLO triggers at 12 V threshold to prevent erratic behavior during brownout. |
| VOA / VOB | Isolated gate driver outputs | Current-source outputs with integrated Miller clamp; no external gate resistors required for optimal switching. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels set via SPD+/SPD− resistors - replaces gate resistors and enables dynamic speed tuning. |
| Integrated Miller Clamp | Automatically engages when VOA/VOB falls below VMCTA/B (~2 V) - suppresses Miller-induced shoot-through without external components. |
| Programmable Dead Time | Resistor-controlled DT pin sets channel-to-channel delay (10–110 kΩ → ~10–120 ns) - prevents cross-conduction in half-bridge topologies. |
| High CMTI & Low Skew | CMTI > 200 kV/μs and skew < 5 ns - maintains signal integrity in fast-switching SiC/GaN applications up to 2 MHz. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C) qualification - validated for automotive power electronics including onboard chargers and traction inverters. |
| No Unknown Output States | Defined VOA/VOB = low during UVLO, EN = low, DIS = high, or power loss - eliminates risk of unintended FET 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 |
|---|---|---|---|
| Si8239AD-IS3 | Same NB SOIC-16 package and universal configuration, but uses DISABLE (DIS) instead of ENABLE (EN) logic; identical SelVCD™, CMTI, and isolation specs. | Requires inverted control logic: DIS = high disables outputs, whereas SI82F39AEE-IS3 uses EN = low to disable. | Select Si8239AD-IS3 only if system controller natively asserts active-high disable signals without inversion logic. |
| UCC5390SCD | TI's 5.7 kVRMS isolated dual driver with 10 A peak output, but fixed 10 ns propagation delay and no SelVCD™; requires external Miller clamp diodes. | Better suited for ultra-high-current IGBTs where ±10 A drive is mandatory, but lacks programmable current and integrated clamp. | Choose UCC5390SCD only when peak current demand exceeds ±4 A and board space permits external clamping components. |
Compared with SI82F39AEE-IS3, Si8239AD-IS3 offers identical performance with inverted enable polarity, while UCC5390SCD trades programmability and integration for higher peak current - making SI82F39AEE-IS3 optimal for compact, efficient SiC/GaN designs requiring design flexibility.

FAQ
What is the isolation voltage rating of the SI82F39AEE-IS3?
The SI82F39AEE-IS3 is rated for 6 kVRMS isolation for 1 minute per UL 1577 and provides 1500 VRMS working voltage. This reinforced insulation meets VDE 60747-17, CSA 62368-1, and GB4943.1 standards - confirming suitability for functional safety-critical applications such as automotive traction inverters and medical power supplies where galvanic separation is mandatory.
Does the SI82F39AEE-IS3 support both high-side and low-side gate driving in the same package?
Yes, the SI82F39AEE-IS3 is configured as a universal dual-channel driver: VOA responds to VIA and VOB responds to VIB, allowing independent control of two switches - whether configured as high-side/low-side in a half-bridge or as two separate low-side drivers. Its DT pin can be used to insert programmable dead time or disabled to operate as fully independent channels.
How does the SelVCD™ feature eliminate the need for external gate resistors in the SI82F39AEE-IS3?
SelVCD™ makes the SI82F39AEE-IS3's outputs behave as precision current sources - sourcing and sinking current is set via SPD+/SPD− resistors to one of eight levels (±0.5 A to ±4 A). Because output current is actively regulated, external gate resistors are unnecessary for controlling dV/dt or switching speed, and the integrated Miller clamp engages automatically during turn-off transitions without added components.
What is the purpose of the DT pin on the SI82F39AEE-IS3, and how is it configured?
The DT pin on the SI82F39AEE-IS3 programs dead time between VOA and VOB transitions using an external resistor (10–110 kΩ) to GND, yielding ~10–120 ns delay. When tied to VDDI, dead time and overlap protection are disabled - enabling pure dual-driver operation. This flexibility allows the same SI82F39AEE-IS3 to serve both half-bridge and independent switch applications without redesign.
Is the SI82F39AEE-IS3 qualified for automotive applications?
Yes, the SI82F39AEE-IS3 is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C), manufactured using automotive-specific process flows, and certified to 62368-1 (2 MOPP) and 60601-1 (medical) safety standards. Its 6 kVRMS isolation, 10 kV bipolar surge rating, and defined fault states make it suitable for EV onboard chargers, DC-DC converters, and traction inverter auxiliary drives.
