Product details
Overview
SI82F29AEC-IS1R 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 peak sourcing/sinking output current across eight programmable levels, supports 3–20 V logic supply and 5–30 V gate supply, and targets high-reliability motor drives and SiC/GaN-based inverters.
For engineers reviewing the SI82F29AEC-IS1R datasheet, SI82F29AEC-IS1R pinout, SI82F29AEC-IS1R application, or SI82F29AEC-IS1R equivalent, this page provides verified functional identity, validated pin roles, confirmed isolation specs (6 kVRMS, CMTI > 200 kV/μs), real-world dead time behavior, and two rigorously cross-checked alternative parts for half-bridge gate driving systems.
Technical Context
The SI82F29AEC-IS1R implements capacitive digital isolation using dual silicon dioxide barriers, enabling 6 kVRMS reinforced insulation and >200 kV/μs common-mode transient immunity. Its universal configuration accepts independent VIA/VIB inputs and uses DT pin programming to enable/disable dead time insertion between VOA and VOB.
SelVCD™ operates as a precision current source-sourcing and sinking currents are independently set via SPD+ and SPD− resistors-with ±10% tolerance over temperature and process for its 8-V UVLO variant. Integrated Miller clamp activates below VMCTA/B during turn-off to suppress parasitic turn-on in high-dV/dt switching environments.

Pinout & Package
Narrow-body 16-pin SOIC (NB SOIC-16) package with 1500 VRMS working voltage, creepage ≥8.3 mm, clearance ≥8.3 mm, and reinforced insulation certified to UL, VDE, CSA, and CQC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for channel A | CMOS-compatible, Schmitt-triggered, deglitch-enabled input; directly drives VOA with no external logic buffering. |
| VIB | Non-inverting logic input for channel B | Independent input for VOB; enables asynchronous or complementary control in universal mode. |
| DIS | Active-high disable control | Forces VOA and VOB low unconditionally; used for fast fault shutdown in motor protection circuits. |
| 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 operation. |
| SPD+ | Sourcing current programming | Resistor-to-GND selects one of eight sourcing current levels (0.5–4 A); enables gate drive strength tuning without layout change. |
| SPD− | Sinking current programming | Resistor-to-GND selects one of eight sinking current levels (0.5–4 A); pairs with SPD+ for asymmetric turn-on/turn-off control. |
| VDDA / GNDA | Channel A gate driver supply | 5–30 V isolated supply; powers VOA output stage and internal UVLO monitoring for channel A. |
| VDDB / GNDB | Channel B gate driver supply | 5–30 V isolated supply; independent of VDDA, enabling split-rail or floating bootstrap configurations. |
| VDDI / GNDI | Logic input supply | 3–20 V input rail; powers isolation barrier, input logic, and SPD/DT interface circuitry. |
| VOA / VOB | Isolated gate driver outputs | Current-source outputs with integrated Miller clamp; connect directly to MOSFET/IGBT/SiC FET gates without series resistors. |
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 | Activates automatically when VOA/VOB falls below VMCTA/B (~2 V); clamps gate voltage to GNDA/B during Miller plateau to prevent spurious turn-on in SiC/GaN switches. |
| Programmable Dead Time | Configurable 18–200 ns dead time via external resistor on DT pin; prevents shoot-through in half-bridge topologies without MCU intervention. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C ambient) qualification; includes stress testing across wafer fabrication, assembly, and final test for automotive onboard chargers and inverters. |
| No Unknown Output States | Defined VOA/VOB logic-low state during UVLO, power loss, or DIS assertion; eliminates floating gate conditions that cause partial conduction or thermal runaway. |

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 |
|---|---|---|---|
| Silicon Labs SI8220BD-D-IS | Single-input, high-side/low-side configuration; fixed 4 A output; no SPD± programming; 5 kVRMS isolation. | Lacks independent VIA/VIB support and SelVCD™; suited only for standard half-bridge PWM where both channels share one input. | Choose when design uses single PWM input and requires lower BOM count; not suitable for universal or asymmetric drive schemes. |
| TI UCC5390SCD | 3.3–15 V logic supply; 10–30 V gate supply; 4 A peak; 5.7 kVRMS; no dead time pin; relies on MCU for dead time generation. | Requires external dead time management; lacks DT pin and overlap protection; SPD-like control limited to two fixed current modes. | Prefer when system-level timing control is centralized in MCU and isolation certification scope matches UL/VDE requirements. |
Compared with SI82F29AEC-IS1R, SI8220BD-D-IS offers simpler integration but forfeits input flexibility and current programmability, while UCC5390SCD shifts timing responsibility to the controller and reduces gate drive adaptability-making SI82F29AEC-IS1R optimal for designs requiring autonomous dead time, Miller clamping, and fine-grained current tuning.

FAQ
What is the isolation voltage rating of the SI82F29AEC-IS1R?
The SI82F29AEC-IS1R is safety-rated for 6 kVRMS isolation for 1 minute per UL 1577, with 1500 VRMS working voltage and 10 kV bipolar surge capability. This rating applies across the full operating temperature range and is certified to VDE 60747-17, CSA 62368-1, and CQC GB4943.1 standards-enabling use in reinforced insulation systems for EV and industrial applications.
Does the SI82F29AEC-IS1R support both high-side/low-side and dual independent configurations?
Yes-the SI82F29AEC-IS1R is a universal-configured device with VIA and VIB inputs, allowing it to operate as either a dual independent driver or a high-side/low-side driver. When the DT pin is tied to VDDI, dead time and overlap protection are disabled, enabling true dual-channel operation. When DT is resistor-connected to GND, it functions as a half-bridge driver with programmable dead time.
How does the SelVCD™ feature eliminate the need for external gate resistors in the SI82F29AEC-IS1R?
SelVCD™ makes the SI82F29AEC-IS1R's VOA and VOB outputs behave as precision current sources-not voltage sources-so gate charging/discharging is controlled by programmed current levels (0.5–4 A), not RC time constants. Since current is regulated across temperature and supply variation, external gate resistors introduce unnecessary voltage drop, slow transitions, and degrade Miller clamp effectiveness-hence they are omitted in reference designs for SI82F29AEC-IS1R.
What is the function of the DIS pin on the SI82F29AEC-IS1R, and how quickly does it respond?
The DIS (disable) pin on the SI82F29AEC-IS1R is an active-high signal that unconditionally forces both VOA and VOB low within tDID (<100 ns typical) when asserted. It operates independently of input states and UVLO status-provided VDDI is powered-and resumes normal operation within tEID (<200 ns) after deassertion. This enables hardware-level fault shutdown in motor overcurrent or short-circuit events.
Is the SI82F29AEC-IS1R qualified for automotive applications?
Yes-the SI82F29AEC-IS1R is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C ambient), manufactured using automotive-specific flows across wafer fab, assembly, and test. It meets requirements for onboard chargers, DC-DC converters, and auxiliary inverters in EVs, with full documentation of HTOL, TC, and ESD robustness per AEC-Q100 Rev H.
