Product details
Overview
SI82F29ACE-IS3R from Skyworks Solutions is a dual-channel isolated gate driver with Universal configuration, Disable (DIS) input, and SelVCD™ current drive. It delivers 8 selectable sourcing/sinking current levels, <5 ns channel-to-channel skew, 200 kV/µs CMTI, and 6 kVRMS isolation for driving SiC/GaN FETs in half-bridge motor inverters. Operates from 3–20 V logic supply and 5–30 V gate supply.
For engineers reviewing the SI82F29ACE-IS3R datasheet, SI82F29ACE-IS3R pinout, SI82F29ACE-IS3R application, or SI82F29ACE-IS3R equivalent, this page provides verified functional identity, validated pin mapping to narrow-body SOIC-16, confirmed UVLO options (4 V/8 V/12 V/15 V), SelVCD™ current calibration data, and automotive-grade AEC-Q100 qualification status - all directly extracted from Skyworks' May 2024 Preliminary Data Sheet 206821A.
Technical Context
The SI82F29ACE-IS3R implements capacitive digital isolation using dual SiO₂ barriers with RF OOK modulation, enabling robust noise immunity and precise timing. Its Universal configuration supports independent high-side/low-side control via VIA/VIB inputs, with DIS-driven shutdown forcing both outputs low regardless of input state.
It integrates programmable dead time via external resistor on DT pin (10–110 kΩ), Miller clamp activation below VMCTA/B threshold, and SelVCD™ current source operation with ±10% tolerance over temperature for 8 V/12 V/15 V UVLO variants - matching the SI82F29x family's specified performance envelope.

Narrow-body 16-pin SOIC package (SOIC-16 NB) with 1.27 mm pitch and creepage ≥8.0 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 driver A | Directly controls VOA output state; CMOS-compatible with deglitch filter option. |
| VIB | Non-inverting logic input for driver B | Directly controls VOB output state; independent of VIA for dual-driver operation. |

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-IS3R | Enable (EN) input instead of DIS; identical pinout, isolation, and SelVCD™ capability. | Preferred where active-high enable logic aligns with system controller architecture; requires inverted signal conditioning if DIS logic is mandated. | Select SI8239AD-IS3R only when system-level control logic uses enable-active signaling and no hardware inversion is feasible. |
| UCC5390SCDWR | TI part with 5.7 kVRMS isolation, 150 kV/µs CMTI, and fixed 4-A peak drive; no SelVCD™ or programmable dead time. | Better suited for cost-sensitive industrial drives where fixed drive strength suffices and dynamic current tuning is unnecessary. | Choose UCC5390SCDWR when design prioritizes lower BOM count over tunable gate drive and does not require automotive qualification. |
Compared with SI82F29ACE-IS3R, SI8239AD-IS3R offers identical isolation and current drive but differs in control polarity, while UCC5390SCDWR trades programmability and AEC-Q100 for lower cost and simpler implementation - making SI82F29ACE-IS3R optimal for automotive and high-reliability SiC/GaN systems demanding precision and flexibility.

FAQ
What is the isolation rating and safety certification status of SI82F29ACE-IS3R?
The SI82F29ACE-IS3R provides 6 kVRMS isolation for 1 minute and is pending UL 1577 recognition, CSA 62368-1 (reinforced insulation), VDE 60747-17 (reinforced insulation), and CQC GB4943.1 certifications. Its 1500 VRMS working voltage and 10 kV bipolar surge rating meet stringent safety requirements for automotive and industrial power systems. All certifications apply directly to the SI82F29ACE-IS3R device as specified in Skyworks Preliminary Data Sheet 206821A.
Does SI82F29ACE-IS3R support both high-side/low-side and dual independent gate drive configurations?
Yes, SI82F29ACE-IS3R operates in Universal configuration, supporting both modes. When DT is connected to GND, it functions as a high-side/low-side driver with programmable dead time and overlap protection. When DT is tied to VDDI, dead time and overlap protection are disabled, allowing independent control of VOA via VIA and VOB via VIB - effectively operating as two isolated single-channel drivers. This dual-mode flexibility is confirmed in Figures 1–4 and Section 1.1.1 of the SI82F29ACE-IS3R datasheet.
How does the SelVCD™ technology in SI82F29ACE-IS3R eliminate the need for external gate resistors?
SelVCD™ makes SI82F29ACE-IS3R's outputs behave as precision current sources - sourcing and sinking current is set via SPD+ and SPD− pins across eight discrete levels, with ±10% tolerance over temperature for 8 V/12 V/15 V UVLO variants. Because output current is actively regulated, external gate resistors are unnecessary for controlling dV/dt or limiting peak current. Removing them also enables the integrated Miller clamp to operate directly at the FET gate, improving turn-off speed and EMI performance - as explicitly stated in Sections 1 and 4.6 of the datasheet.
What is the function of the DIS pin on SI82F29ACE-IS3R, and how does it differ from EN?
The DIS (Disable) pin on SI82F29ACE-IS3R is an active-high signal that unconditionally forces both VOA and VOB outputs low, overriding all other inputs including VIA, VIB, and UVLO state. It terminates operation within tDID (<100 ns typical) and resumes normal function within tEID after deassertion. Unlike EN (used in SI82F39x variants), DIS asserts on logic high, making it compatible with systems where fault signals are active-high. This behavior is documented in Table 1 (Pin Details) and Section 4.4.2 of the SI82F29ACE-IS3R datasheet.
Is SI82F29ACE-IS3R qualified for automotive applications, and what does AEC-Q100 qualification entail for this part?
Yes, SI82F29ACE-IS3R is AEC-Q100 qualified. This means it was manufactured using automotive-specific process flows at every stage - wafer fabrication, assembly, and test - to ensure low defectivity, robustness against mechanical stress, and long-term reliability under harsh conditions (–40 °C to +125 °C). The qualification covers HTOL, TC, UHAST, and ESD testing per AEC-Q100 Rev H, and applies specifically to the SI82F29ACE-IS3R device variant as noted in the "Automotive Grade" section of the datasheet.
