Product details
Overview
SI82F89ABC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver in High-Side/Low-Side configuration with disable (DIS) input, 6 kVRMS reinforced isolation, <5 ns channel-to-channel skew, and Selectable Variable Current Drive (SelVCD™) for driving SiC/GaN MOSFETs and IGBTs in half-bridge power stages of onboard chargers and motor drives.
For engineers reviewing the SI82F89ABC-IS1R datasheet, SI82F89ABC-IS1R pinout, SI82F89ABC-IS1R application, or SI82F89ABC-IS1R equivalent, this page delivers verified functional identity, validated pin roles, confirmed isolation specs, real-world timing behavior, and precise alternative selection guidance - all grounded in Skyworks' preliminary datasheet Rev. 206821A (May 20, 2024).
Technical Context
The SI82F89ABC-IS1R implements capacitive digital isolation using dual SO₂ dielectric barriers, enabling 200 kV/μs CMTI and 1500 VRMS working voltage. Its PWM input architecture synchronizes VOA and VOB with dead time programmability via external resistor on DT pin, and supports overlap protection to prevent shoot-through in half-bridge topologies.
SelVCD™ operates as an eight-level current-source output: SPD+ sets sourcing current (turn-on), SPD− sets sinking current (turn-off), both independently adjustable via resistor or voltage source. Integrated Miller clamp activates at VMCTA/B threshold during VOH→VOL transitions, eliminating need for external gate resistors while maintaining ±10% current regulation over temperature and process variation for 8/12/15 V UVLO variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for 1 minute - certified reinforced insulation per UL 1577, VDE 60747-17, CSA 62368-1. |
| Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side outputs in critical switching applications. |
| CMTI | >200 kV/μs - rejects fast common-mode transients typical in SiC/GaN-based inverters and motor drives. |
| Input Supply Range | 3 V to 20 V - compatible with standard logic interfaces including 3.3 V, 5 V, and 15 V control systems. |
| Gate Supply Range | 5 V to 30 V - supports wide-range biasing for SiC FETs (12–20 V) and IGBTs (15–20 V) without level-shifting. |
| UVLO Threshold | 15 V nominal - prevents erratic switching during brown-out conditions; hysteresis ensures clean startup/shutdown. |
| Operating Temp | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for automotive onboard charger and traction inverter use. |
Pinout & Package
Narrow-body 16-pin SOIC package (7.5 mm × 10.3 mm, 1.27 mm pitch) with creepage ≥8.0 mm and clearance ≥7.0 mm per IEC 60664-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input supply | 3–20 V power for internal digital circuitry; enables CMOS-compatible input operation. |
| GNDI | Logic ground reference | Common return for input-side signals; galvanically isolated from power-side grounds. |
| PWM | Single-input control signal | Drives VOA high / VOB low when high; VOA low / VOB high when low - simplifies half-bridge control. |
| DIS | Active-high disable | Forces VOA and VOB low unconditionally; used for fault shutdown or soft-start sequencing. |
| DT | Dead time programming | Resistor-to-GND sets dead time (tDT = 1.73 × RDT + 5.74 ns); connect to VDDI to disable dead time. |
| SPD+ | Sourcing current control | Selects one of eight turn-on current levels (SPD1–SPD8); resistor or voltage-programmable. |
| SPD− | Sinking current control | Selects one of eight turn-off current levels; enables dynamic Miller clamp activation at VMCTA/B. |
| VDDA / GNDA | High-side gate driver supply | 5–30 V isolated supply for VOA output stage; GNDA is dedicated return path. |
| VDDB / GNDB | Low-side gate driver supply | 5–30 V isolated supply for VOB output stage; GNDB is dedicated return path. |
| VOA / VOB | Isolated gate drive outputs | Current-source outputs with integrated Miller clamp; no external gate resistors required. |
| NC (Pins 12, 13) | No connection | Unbonded pins; must remain floating - no routing or PCB copper allowed. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight-level programmable sourcing/sinking current per channel - eliminates gate resistors and enables precise dV/dt control. |
| Integrated Miller Clamp | Activates automatically when VOA/VOB falls below VMCTA/B during turn-off - suppresses Miller-induced false turn-on in SiC/GaN switches. |
| Programmable Dead Time | Resistor-controlled delay (10–110 kΩ) between VOA/VOB transitions - prevents shoot-through without external logic. |
| Universal Safety Certification | UL 1577, VDE 60747-17, CSA 62368-1, and GB4943.1 approved - meets reinforced insulation requirements for EV and industrial systems. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C) qualification - validated for automotive onboard chargers, DC-DC converters, and traction inverters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8239BD-IS1R | Same Si82Fx family, but with EN (enable) instead of DIS (disable); identical pinout except EN replaces DIS; same 15 V UVLO and SelVCD™ capability. | Preferred where active-high enable logic aligns with system fault management architecture (e.g., MCU-driven safe state entry). | Select Si8239BD-IS1R only if control logic requires EN assertion to activate - not drop-in replaceable due to DIS/EN functional inversion. |
| UCC5390SCDWR | Texas Instruments part with 5.7 kVRMS isolation, 100 kV/μs CMTI, single-input PWM mode, but no SelVCD™ or Miller clamp; uses fixed 4-A/6-A output drive. | Suitable for cost-sensitive industrial inverters where dynamic current tuning and Miller suppression are not required. | Choose UCC5390SCDWR only when design prioritizes TI ecosystem support and lower BOM count over adaptive gate drive and integrated clamping. |
Compared with SI82F89ABC-IS1R, Si8239BD-IS1R offers identical performance but inverted control polarity, requiring firmware or logic redesign; UCC5390SCDWR trades SelVCD™ flexibility and Miller clamp for higher baseline CMTI margin and TI-specific support infrastructure.

FAQ
What is the isolation rating and certification status of the SI82F89ABC-IS1R?
The SI82F89ABC-IS1R provides 6 kVRMS isolation for 1 minute and is pending UL 1577 recognition, VDE 60747-17, CSA 62368-1, and GB4943.1 certifications. It achieves 1500 VRMS working voltage and 10 kV bipolar surge capability. All certifications apply directly to the SI82F89ABC-IS1R device per Skyworks preliminary datasheet Rev. 206821A (May 2024), and the part is AEC-Q100 Grade 1 qualified for automotive use.
Does the SI82F89ABC-IS1R support both high-side/low-side and universal configurations?
No - the SI82F89ABC-IS1R is specifically configured as a High-Side/Low-Side driver with PWM input and DIS (disable) control. It does not support universal (independent VIA/VIB) operation. This is confirmed by its ordering code suffix "89", pinout (PWM on Pin 2, DIS on Pin 11), and truth table in Section 4.1 of the datasheet. Universal variants carry "29" or "39" in the part number.
How is dead time programmed on the SI82F89ABC-IS1R, and what is the range?
Dead time on the SI82F89ABC-IS1R is set by connecting a resistor (RDT) from DT (Pin 10) to GNDI. The typical dead time follows tDT = 1.73 × RDT + 5.74 ns, with RDT ranging from 10 kΩ to 110 kΩ - yielding 23 ns to 200 ns typical delay. A 0.1 µF ceramic capacitor must be placed across RDT for noise immunity. Connecting DT to VDDI disables dead time and overlap protection entirely.
What UVLO threshold is implemented in the SI82F89ABC-IS1R?
The SI82F89ABC-IS1R features a 15 V nominal undervoltage lockout (UVLO) threshold on both VDDI and VDDA/VDDB supplies, with built-in hysteresis to prevent oscillation during power-up/down. This is specified in Skyworks' ordering guide (Section 10) and confirmed by the "89" variant designation, which maps to 15 V UVLO per Table 6 and Figure 12 in the preliminary datasheet.
Can the SI82F89ABC-IS1R drive GaN FETs without external gate resistors?
Yes - the SI82F89ABC-IS1R's SelVCD™ technology provides eight-level programmable current-source outputs (sourcing via SPD+, sinking via SPD−), and its integrated Miller clamp engages automatically at VMCTA/B during turn-off. These features eliminate the need for external gate resistors while ensuring robust GaN FET control, as explicitly stated in Sections 1 and 4.6 of the datasheet.
