Product details
Overview
SI82F99ECC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver in high-side/low-side configuration with enable (EN) input, 6 kVRMS reinforced isolation, <5 ns channel-to-channel skew, and Selectable Variable Current Drive (SelVCD™) supporting eight current levels for MOSFET/IGBT/SiC/GaN switching. It operates with 3–20 V logic supply and 5–30 V gate drive supply, targeting half-bridge motor drives and onboard chargers.
For engineers reviewing the SI82F99ECC-IS1R datasheet, SI82F99ECC-IS1R pinout, SI82F99ECC-IS1R application, or SI82F99ECC-IS1R equivalent, this page delivers verified functional identity, validated pin mapping to narrow-body SOIC-16, confirmed SelVCD™ current regulation behavior, UVLO thresholds (4 V/8 V/12 V/15 V), and automotive-grade AEC-Q100 qualification status - all directly traceable to Skyworks' May 2024 preliminary datasheet.
Technical Context
The SI82F99ECC-IS1R implements a high-side/low-side topology using differential capacitive isolation with RF-modulated OOK signaling across dual SiO₂ barriers, enabling 200 kV/μs CMTI and stable timing over temperature. Its dead time control uses an external resistor on DT pin to set programmable delay between VOA and VOB transitions, with overlap protection preventing shoot-through during simultaneous high inputs.
SelVCD™ operates as a precision current source: SPD+ sets sourcing current (turn-on), SPD− sets sinking current (turn-off), both independently adjustable across eight levels via resistor or voltage programming. Integrated Miller clamp activates automatically when VOA/VOB falls below VMCTA/B, delivering maximum sink current (SPD7−) without external components.
Key Specifications

Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with 1.27 mm pitch; creepage ≥8.0 mm, clearance ≥7.5 mm; RoHS-compliant, halogen-free.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for gate driver A | Accepts CMOS-level PWM or control signal; active-high, Schmitt-triggered, deglitch-filtered. |
| VIB | Non-inverting logic input for gate driver B | Independent input for second channel; enables asynchronous control in universal mode (not used in SI82F99x). |
| EN | Active-high enable input | Drives VOA/VOB low when deasserted; terminates operation within tDID, resumes within tEID. |
| DT | Dead time programming input | Resistor-to-GND sets dead time (tDT = 1.73 × RDT + 5.74 ns); tied to VDDI disables dead time for dual-driver mode. |
| SPD+ | Sourcing current programming input | Selects turn-on current level (8 settings); resistor or voltage control determines output drive strength into gate capacitance. |
| SPD− | Sinking current programming input | Selects turn-off current level (8 settings); enables fast Miller discharge and integrated clamp activation at VMCTA/B. |
| VDDA / GNDA | High-side gate driver power and ground | Supplies isolated high-side output stage; independent UVLO monitoring prevents false turn-on during undervoltage. |
| VDDB / GNDB | Low-side gate driver power and ground | Supplies isolated low-side output stage; supports separate biasing for asymmetric half-bridge configurations. |
| VOA / VOB | High-side and low-side gate driver outputs | Current-source outputs with built-in Miller clamp; no external gate resistors required for optimal switching performance. |
| VDDI / GNDI | Logic input power and ground | 3–20 V supply domain; powers digital isolation barrier and input logic; includes UVLO monitoring (VDDIUV±). |
| NC (Pins 12,13) | No connection | Unbonded pins; must remain unconnected to avoid parasitic coupling or ESD path disruption. |
Key Features
