Product details
Overview
SI82F29AEE-IS3 from Skyworks Solutions is a dual-channel isolated gate driver with Universal configuration, Disable (DIS) input, and SelVCD™ current-source output architecture. It delivers 6 kVRMS isolation, <5 ns channel-to-channel skew, and programmable dead time for half-bridge motor drives and inverters using SiC/GaN FETs. Its CMOS inputs operate from 3–20 V, gate supplies support 5–30 V, and integrated Miller clamp eliminates external gate resistors.
For engineers reviewing the SI82F29AEE-IS3 datasheet, SI82F29AEE-IS3 pinout, SI82F29AEE-IS3 application, or SI82F29AEE-IS3 equivalent, this page provides verified functional identity, validated pin mapping for WB SOIC-14, confirmed SelVCD™ current levels, UVLO thresholds, CMTI >200 kV/μs, and automotive-grade AEC-Q100 qualification status - all specific to SI82F29AEE-IS3 per Skyworks Preliminary Data Sheet 206821A.
Technical Context
The SI82F29AEE-IS3 implements capacitive digital isolation using dual silicon dioxide (SiO₂) capacitors with RF OOK modulation, enabling high noise immunity and precise timing. Its Universal configuration supports independent control of two gate drivers via VIA and VIB inputs, with DIS-driven shutdown forcing both outputs low regardless of input state.
It features analog SPD± pins that set sourcing/sinking current across eight discrete levels (SPD1–SPD7), operating as a tightly regulated current source (±10% tolerance over temp/process for 8/12/15 V UVLO variants). The Miller clamp activates automatically when VOA/VOB falls below VMCTA/B during turn-off, enhancing dV/dt immunity without external components.

Pinout & Package
SI82F29AEE-IS3 uses a wide-body 14-pin SOIC (WB SOIC-14) package with creepage ≥8.3 mm and clearance ≥8.3 mm, optimized for reinforced insulation in high-voltage systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for driver A | CMOS-compatible Schmitt-triggered input; controls VOA directly in Universal mode. |
| VIB | Non-inverting logic input for driver B | CMOS-compatible Schmitt-triggered input; controls VOB directly in Universal mode. |
| DIS | Active-high disable control | Unconditionally forces VOA and VOB low when asserted; overrides all other inputs including power state. |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~10–120 ns); connect to VDDI to disable dead time and overlap protection. |
| SPD+ | Sourcing current programming | Sets VOA/VOB turn-on current across 8 levels (SPD1–SPD7); resistor or voltage-controlled interface. |
| SPD− | Sinking current programming | Sets VOA/VOB turn-off current across 8 levels; enables dynamic Miller clamp activation at VMCTA/B threshold. |
| 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 | Driver A gate supply | 5–30 V supply for high-side or independent driver A output stage; includes dedicated UVLO monitoring. |
| GNDA | Driver A ground | Return path for VDDA and VOA; isolated from GNDB and GNDI to maintain channel separation. |
| VDDB | Driver B gate supply | 5–30 V supply for low-side or independent driver B output stage; independently monitored UVLO. |
| GNDB | Driver B ground | Return path for VDDB and VOB; maintains isolation integrity between channels and logic side. |
| VOA | Driver A output | Current-source output with integrated Miller clamp; connects directly to power switch gate without series resistor. |
| VOB | Driver B output | Current-source output with integrated Miller clamp; operates identically to VOA with independent SPD± control. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels per channel, adjustable via SPD± resistors or analog voltage - eliminates gate resistors and enables adaptive switching speed. |
| Integrated Miller Clamp | Automatically engages when VOA/VOB falls below VMCTA/B during turn-off, clamping Miller-induced dv/dt spikes without external diodes or resistors. |
| Programmable Dead Time | User-configurable delay (10–120 ns typical) between VOA/VOB transitions via single DT resistor - prevents shoot-through in half-bridge configurations. |
| High CMTI & Low Skew | 200 kV/μs common-mode transient immunity and <5 ns channel-to-channel skew - ensures timing integrity in fast-switching SiC/GaN systems. |
| Robust Input Interface | CMOS/Schmitt-triggered VIA/VIB/DIS inputs with optional deglitch filter - rejects noise up to 50 ns while maintaining <35 ns propagation delay. |
| Fail-Safe Output States | No undefined outputs: VOA/VOB default to logic low during UVLO, power loss, or DIS assertion - prevents 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 |
|---|---|---|---|
| SI8239AD-IS3 | Same WB SOIC-14 package and Universal configuration, but uses EN (enable) instead of DIS (disable); identical SelVCD™, isolation, and timing specs. | Requires active-high enable signal instead of active-high disable; truth table behavior differs during control assertion. | Select SI8239AD-IS3 only if system-level control logic is designed around enable-driven startup rather than disable-driven fault shutdown. |
| UCC5390SCD | TI's 5.7 kVRMS capacitive isolator with 30 V max VDD, but fixed 4-A peak output (no SelVCD™), no SPD± programming, and no integrated Miller clamp. | Lacks dynamic current adjustment and Miller clamping; requires external gate resistors and clamping diodes for SiC/GaN. | Choose UCC5390SCD only for cost-sensitive, lower-performance applications where fixed-current drive and external component overhead are acceptable. |
Compared with SI82F29AEE-IS3, SI8239AD-IS3 offers identical isolation and timing but inverted control polarity, while UCC5390SCD lacks current programmability and integrated Miller clamping - making SI82F29AEE-IS3 uniquely suited for adaptive, high-reliability SiC/GaN gate drive where layout simplicity and dV/dt immunity are critical.

FAQ
What is the isolation rating and safety certification status of SI82F29AEE-IS3?
SI82F29AEE-IS3 provides 6 kVRMS isolation for 1 minute and is pending UL 1577 recognition, CSA 62368-1 (reinforced insulation), VDE 60747-17, and CQC GB4943.1 certifications. Its 1500 VRMS working voltage and 10 kV bipolar surge capability meet reinforced insulation requirements for industrial and automotive applications. All certifications apply specifically to SI82F29AEE-IS3 per Skyworks Preliminary Data Sheet 206821A.
Does SI82F29AEE-IS3 support both high-side/low-side and dual independent configurations?
SI82F29AEE-IS3 is configured as a Universal driver - it supports dual independent control via VIA and VIB inputs, not PWM-based high-side/low-side pairing. Dead time and overlap protection are programmable via the DT pin but can be disabled by connecting DT to VDDI, allowing true independent channel operation. This differs from Si82F89x/Si82F99x variants which use PWM input and fixed HSL topology.
How does the SelVCD™ technology in SI82F29AEE-IS3 eliminate the need for external gate resistors?
SI82F29AEE-IS3 implements SelVCD™ as a precision current-source output stage, where SPD+ and SPD− pins set sourcing and sinking current across eight discrete levels. Because output current is actively regulated (±10% over temperature/process), gate charging/discharging is controlled directly by current magnitude - eliminating series gate resistors required in voltage-mode drivers. This also enables the integrated Miller clamp to function effectively at the VOA/VOB pin.
What is the function of the DIS pin on SI82F29AEE-IS3, and how does it differ from EN?
The DIS (Disable) pin on SI82F29AEE-IS3 is an active-high signal that unconditionally forces both VOA and VOB low, overriding all other inputs and power states. Unlike EN (Enable) used in SI82F39x variants, DIS asserts fault shutdown rather than enabling normal operation. This makes SI82F29AEE-IS3 ideal for safety-critical systems where immediate, deterministic output deactivation is required during fault events.
Is SI82F29AEE-IS3 qualified for automotive applications, and what grade does it meet?
Yes, SI82F29AEE-IS3 is AEC-Q100 qualified and designated as Automotive Grade 1, meaning it has passed full stress testing for operation from –40 °C to +125 °C ambient, including HTOL, TC, and ESD (4 kV HBM). It is manufactured using automotive-specific process flows at all stages to ensure low defectivity and long-term reliability in powertrain and charging systems.
