Product details
Overview
SI82F29ABE-IS3R from Skyworks Solutions is a dual-channel isolated gate driver in narrow-body 16-pin SOIC package, configured as a universal driver with disable (DIS) input, 8-V UVLO, and SelVCD™ current drive. It delivers up to 4 A sourcing/sinking output current across eight programmable levels, supports 3–20 V logic supply and 5–30 V gate supply, and targets high-reliability half-bridge and dual-switch motor inverter stages.
For engineers reviewing the SI82F29ABE-IS3R datasheet, SI82F29ABE-IS3R pinout, SI82F29ABE-IS3R application, or SI82F29ABE-IS3R equivalent, this page provides verified functional identity, validated pin roles, confirmed isolation specs (6 kVRMS, CMTI > 200 kV/μs), exact UVLO threshold (8 V), and real-world dead time and Miller clamp behavior - all directly traceable to Skyworks' preliminary datasheet Rev. 206821A.
Technical Context
The SI82F29ABE-IS3R implements capacitive digital isolation using dual SiO₂ barriers with RF OOK modulation, enabling precise timing control and fault-tolerant signal transfer between logic and power domains. Its universal configuration accepts independent VIA/VIB inputs and uses DIS for unconditional output disable, while DT pin enables resistor-programmable dead time (10–110 kΩ range) or disables overlap protection when tied to VDDI.
SelVCD™ operates as a precision current source: SPD+ and SPD− pins set sourcing/sinking current independently across eight levels, maintaining ±10% tolerance over temperature and process for 8-V UVLO variants. Integrated Miller clamp activates below VMCTA/B during turn-off, delivering peak sinking current without external components.

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 for channel A | Accepts CMOS-level signal; drives VOA high when asserted, independent of VIB state. |
| VIB | Non-inverting logic input for channel B | Accepts CMOS-level signal; drives VOB high when asserted, independent of VIA state. |
| DIS | Active-high disable control | Forces VOA and VOB low unconditionally; overrides all input logic when high. |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~10–190 ns); tie to VDDI to disable overlap protection. |
| SPD+ | Sourcing current programming input | Resistor-to-GND selects one of eight sourcing current levels (0.5–4 A); enables Miller clamp during turn-on. |
| SPD− | Sinking current programming input | Resistor-to-GND selects one of eight sinking current levels (0.5–4 A); triggers Miller clamp activation at VMCTA/B. |
| VDDI | Logic input supply | 3–20 V input power; powers internal logic, isolation modulator, and deglitch filter (if enabled). |
| GNDI | Logic ground reference | Common return for VDDI, VIA, VIB, DIS, DT, SPD+, SPD−; galvanically isolated from power side grounds. |
| VDDA / GNDA | Channel A gate driver supply / ground | 5–30 V isolated supply for VOA output stage; GNDA is dedicated return path for channel A. |
| VDDB / GNDB | Channel B gate driver supply / ground | 5–30 V isolated supply for VOB output stage; GNDB is dedicated return path for channel B. |
| VOA / VOB | Isolated gate driver outputs | Current-source outputs with integrated Miller clamp; directly drive MOSFET/IGBT/SiC/GaN gates without external resistors. |
| NC (Pins 12, 13) | No connection | Unbonded die pads; must remain floating - no PCB trace or component connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels (0.5–4 A) set via SPD+/SPD− resistors - replaces gate resistors and enables adaptive switching loss optimization. |
| Integrated Miller Clamp | Automatically engages when VOA/VOB falls below VMCTA/B (~2 V) - suppresses Miller-induced false turn-on in high-dV/dt SiC/GaN applications. |
| Programmable Dead Time | Resistor-controlled DT pin sets channel-to-channel delay (10–110 kΩ → ~10–190 ns) - prevents shoot-through in half-bridge topologies. |
| Universal Configuration with DIS | Dual independent inputs (VIA/VIB) + active-high disable (DIS) - supports flexible control schemes including PWM + enable, dual PWM, or safety shutdown. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C ambient) qualification - meets automotive reliability requirements for traction inverters and OBCs. |
Applications
| Motor Drives | Onboard Chargers (OBC) |

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 |
|---|---|---|---|
| Si82F39ABE-IS3R | Same NB SOIC-16 package and SelVCD™ architecture, but features EN (enable) instead of DIS (disable) input logic. | Better suited for systems requiring active-high enable with default-disabled startup behavior rather than active-high fault shutdown. | Select SI82F29ABE-IS3R when system-level fault response mandates immediate output disable on signal assertion; Si82F39ABE-IS3R requires inverted control logic for equivalent safety action. |
| UCC5390SCDR | Texas Instruments part with 5.7 kVRMS isolation, 10 A peak output, but fixed 4-A sourcing/sinking and no SelVCD™ or SPD± programming. | Lacks current-level programmability and Miller clamp integration - requires external gate resistors and clamping diodes. | Choose SI82F29ABE-IS3R when design requires adaptive switching speed, reduced BOM count, or tighter skew control (<5 ns vs. UCC5390's 10 ns typical). |
Compared with Si82F39ABE-IS3R, SI82F29ABE-IS3R offers faster fault response via DIS-driven hard disable; compared with UCC5390SCDR, it reduces layout complexity through SelVCD™ and integrated Miller clamp while delivering superior timing precision and automotive qualification.

FAQ
What is the UVLO threshold for SI82F29ABE-IS3R?
The SI82F29ABE-IS3R has an 8 V typical undervoltage lockout (UVLO) threshold on both VDDA and VDDB supplies. When either gate supply drops to or below 8 V − hysteresis, the corresponding output (VOA or VOB) is forced low to prevent partial turn-on of power devices. This value is fixed per device variant and confirmed in Skyworks' ordering guide for SI82F29ABE-IS3R.
Does SI82F29ABE-IS3R support dynamic speed control?
Yes, SI82F29ABE-IS3R supports dynamic speed control via voltage-driven SPD+ and SPD− pins. Applying a controlled analog voltage (within specified min/max bounds per SPD level) enables real-time adjustment of sourcing/sinking current during operation - useful for adaptive dead time compensation or soft-start sequencing. Static resistor programming remains the default method.
What isolation certifications apply to SI82F29ABE-IS3R?
SI82F29ABE-IS3R is pending UL 1577 (6000 VRMS, 1 min), CSA 62368-1 (reinforced insulation), VDE 60747-17 (reinforced insulation), and CQC GB4943.1 certification. Its 6 kVRMS isolation rating and >200 kV/μs CMTI are fully characterized and meet requirements for reinforced insulation in industrial and automotive applications.
Can SI82F29ABE-IS3R drive SiC or GaN FETs directly?
Yes, SI82F29ABE-IS3R is explicitly rated for driving SiC MOSFETs and GaN HEMTs. Its high CMTI (>200 kV/μs), fast propagation (<35 ns), sub-5 ns skew, and integrated Miller clamp eliminate external components typically needed for wide-bandgap devices - enabling clean, robust switching even at >100 V/ns dV/dt.
What is the function of the DT pin on SI82F29ABE-IS3R?
The DT pin on SI82F29ABE-IS3R programs dead time between VOA and VOB transitions using an external resistor (10–110 kΩ) to GND, yielding ~10–190 ns delay. When tied to VDDI, DT disables dead time insertion and overlap protection - reconfiguring SI82F29ABE-IS3R from half-bridge mode to dual independent driver mode.
