Product details
Overview
SI82F29ACC-IS1 from Skyworks Solutions is a dual-channel isolated gate driver in narrow-body 16-pin SOIC package, configured as a universal (independent input) driver with active-low disable (DIS) control. It delivers up to 4 A peak sourcing/sinking current via SelVCD™, supports 3–20 V logic supply and 5–30 V gate supply, and provides 6 kVRMS reinforced isolation for driving SiC and GaN FETs in half-bridge motor inverters.
For engineers reviewing the SI82F29ACC-IS1 datasheet, SI82F29ACC-IS1 pinout, SI82F29ACC-IS1 application, or SI82F29ACC-IS1 equivalent, this page delivers verified functional identity, confirmed pin mapping, validated isolation specs, real-world dead time behavior, and precise SelVCD™ current calibration data - all directly traceable to Skyworks' May 2024 preliminary datasheet.
Technical Context
The SI82F29ACC-IS1 implements dual CMOS-isolated channels using differential RF-modulated capacitive coupling across silicon dioxide barriers, enabling 200 kV/μs CMTI and <5 ns channel-to-channel skew. Its universal configuration accepts independent VIA/VIB inputs and uses DIS to force both outputs low unconditionally.
It integrates programmable dead time via external resistor on DT pin, Miller clamping triggered at VMCTA/B threshold during VO→VOL transitions, and eight-level SelVCD™ current control via SPD+/SPD− analog voltage inputs - all operating without external gate resistors while maintaining ±10% current accuracy over temperature and process for 8 V/12 V/15 V UVLO variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577), reinforced insulation per VDE 60747-17 and CSA 62368-1 |
| Output Current Range | 8 selectable levels: 0.5 A to 4 A peak sourcing/sinking (SPD± resistor-programmed) |
| Propagation Skew | <5 ns max between VOA/VOB outputs - enables precise timing in high-frequency half-bridge switching |
| Input Supply Range | 3 V to 20 V logic supply (VDDI) - compatible with 3.3 V, 5 V, and 15 V controller interfaces |
| Gate Supply Range | 5 V to 30 V (VDDA/VDDB) - supports 12 V and 15 V gate drive for SiC/GaN FETs |
| CMTI | >200 kV/μs - prevents false triggering in noisy high-dV/dt power stages |
| UVLO Threshold | Configurable at 4 V, 8 V, 12 V, or 15 V - ensures clean startup/shutdown of gate drivers |
Pinout & Package
Narrow-body 16-pin SOIC (NB SOIC-16) package with 1.27 mm pitch, creepage ≥8.3 mm, clearance ≥8.3 mm, and reinforced insulation barrier between input and output sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input A | Drives VOA high when asserted; independent of VIB - enables asymmetric PWM control |
| VIB | Non-inverting logic input B | Drives VOB high when asserted; independent of VIA - supports dual independent gate control |
| DIS | Active-high disable | Forces VOA and VOB low regardless of VIA/VIB state - critical for fault shutdown |
| DT | Dead time programming | Resistor-to-GND sets dead time (10–110 kΩ → ~18–200 ns); connect to VDDI to disable |
| SPD+ | Sourcing current control | Analog input setting peak turn-on current (0.5–4 A); 1% resistor to GND selects level |
| SPD− | Sinking current control | Analog input setting peak turn-off current (0.5–4 A); 1% resistor to GND selects level |
| VDDA / GNDA | Channel A gate supply | Independent 5–30 V rail for VOA output - isolates A-side power domain |
| VDDB / GNDB | Channel B gate supply | Independent 5–30 V rail for VOB output - enables split-rail or floating gate biasing |
| VDDI / GNDI | Logic input supply | 3–20 V domain powering CMOS inputs and isolation modulator - galvanically separated |
| VOA / VOB | Gate driver outputs | Current-source outputs with integrated Miller clamp - direct connection to FET gates required |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight precision current levels (0.5–4 A) set via SPD+/SPD− resistors - eliminates gate resistors and enables dynamic speed tuning |
| Integrated Miller Clamp | Automatically engages when VOA/VOB falls below VMCTA/B (~2.5 V) - suppresses Miller-induced shoot-through without external components |
| Programmable Dead Time | Resistor-controlled (10–110 kΩ) dead time insertion between VOA/VOB transitions - prevents cross-conduction in half-bridges |
| Universal Input Configuration | Independent VIA/VIB inputs with DIS override - supports asymmetrical PWM, phase-shifted topologies, and independent switch control |
| High CMTI & Low Skew | 200 kV/μs common-mode transient immunity and <5 ns channel-to-channel skew - ensures robust operation in fast-switching SiC/GaN systems |

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 |
|---|---|---|---|
| SIL1225AD-IM | Single-input, high-side/low-side configuration only; no universal (VIA/VIB) mode; fixed 4 A output | Requires external logic for independent control; lacks SPD± programmability and Miller clamp | Choose when only half-bridge topology is needed and gate current tuning is unnecessary |
| UCC5870QDWJRQ1 | 3.3 V/5 V logic-compatible; integrated DESAT protection; higher 10 A peak output; larger SOIC-16W package | Targets automotive traction inverters with fault diagnostics; requires additional external components for Miller clamp | Choose when DESAT monitoring and >4 A drive are mandatory; accept larger footprint and higher cost |
Compared with SIL1225AD-IM and UCC5870QDWJRQ1, the SI82F29ACC-IS1 uniquely combines universal input flexibility, resistor-programmable SelVCD™ current, and integrated Miller clamping in a standard NB SOIC-16 - enabling compact, resistor-tuned gate drive without external components or layout compromises.

FAQ
What is the isolation voltage rating of the SI82F29ACC-IS1?
The SI82F29ACC-IS1 is rated for 6 kVRMS isolation for 1 minute per UL 1577, with reinforced insulation certified to VDE 60747-17, CSA 62368-1, and CQC GB4943.1. Its working voltage is 1500 VRMS, and it withstands bipolar surges up to 10 kV - making it suitable for high-voltage industrial and automotive power systems where safety-critical isolation is mandated.
Does the SI82F29ACC-IS1 support independent control of both output channels?
Yes, the SI82F29ACC-IS1 uses a universal configuration with separate VIA and VIB inputs, allowing fully independent control of VOA and VOB. This differs from high-side/low-side-only variants and enables asymmetric PWM, phase-shifted topologies, and individual switch enable/disable - all confirmed in the device's truth table and functional block diagram for Si82F29x.
How is dead time programmed on the SI82F29ACC-IS1?
Dead time on the SI82F29ACC-IS1 is set by connecting an external resistor (10 kΩ to 110 kΩ) between the DT pin and GNDI. The typical delay follows tDT = 1.73 × RDT + 5.74 ns. Connecting DT to VDDI disables dead time and overlap protection, reconfiguring the device as a dual independent driver - a feature explicitly documented for Si82F29x in the preliminary datasheet.
What is the function of the SPD+ and SPD− pins on the SI82F29ACC-IS1?
The SPD+ and SPD− pins on the SI82F29ACC-IS1 set the peak sourcing and sinking current levels (0.5 A to 4 A) for both VOA and VOB outputs via resistor dividers to GNDI. Each pin operates as a current-sink input that measures voltage to select one of eight SelVCD™ levels - eliminating gate resistors and enabling precise, matched turn-on/turn-off control without external components.
Is the SI82F29ACC-IS1 qualified for automotive applications?
Yes, the SI82F29ACC-IS1 is AEC-Q100 qualified and offered in automotive-grade OPNs. It is manufactured using automotive-specific flows across wafer fabrication, assembly, and test to ensure low defectivity and robustness - meeting requirements for onboard chargers, DC-DC converters, and auxiliary inverters in passenger and commercial vehicles.
