Product details
Overview
SI82F99ECE-IS3R from Skyworks Solutions is a dual-channel isolated gate driver in High-Side/Low-Side configuration with PWM input, 6 kVRMS reinforced isolation, <5 ns channel-to-channel skew, and Selectable Variable Current Drive (SelVCD™) supporting eight current levels for both sourcing and sinking. It drives SiC/GaN FETs and IGBTs in half-bridge topologies for onboard chargers and motor inverters.
For engineers reviewing the SI82F99ECE-IS3R datasheet, SI82F99ECE-IS3R pinout, SI82F99ECE-IS3R application, or SI82F99ECE-IS3R equivalent, this page delivers verified functional identity, validated pin mapping to SOIC-14 wide-body package, confirmed SelVCD™ current regulation behavior, UVLO thresholds (12 V), and automotive-grade AEC-Q100 qualification status - all directly traceable to Skyworks' preliminary datasheet Rev. 206821A.
Technical Context
The SI82F99ECE-IS3R implements silicon-dioxide capacitive isolation with differential RF-modulated OOK signaling, enabling 200 kV/µs CMTI and stable timing across temperature. Its PWM-input architecture routes a single logic signal to both channels while enforcing dead-time-controlled complementary outputs via external resistor on DT pin.
It integrates independent UVLO monitoring per supply rail (VDDI = 12 V threshold, VDDA/VDDB = 12 V), Miller clamp activation at VMCTA/B ≈ 1.9 V, and analog SPD± inputs that set sourcing/sinking current as precision current sources - not voltage-mode drivers - eliminating external gate resistors and enabling direct Miller clamping at VOA/VOB pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577, VDE 60747-17, CSA 62368-1) |
| Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side drive edges in half-bridge switching |
| Input Supply Range | 3 V to 20 V - supports direct interface with 3.3 V, 5 V, and 12 V logic controllers without level shifting |
| Gate Supply Range | 5 V to 30 V - enables direct drive of SiC FETs requiring ≥15 V gate bias and GaN devices needing precise 5–6 V turn-on |
| UVLO Threshold | VDDI = 12 V (typical), VDDA/VDDB = 12 V - prevents erratic switching during brown-out conditions in automotive OBC and traction inverters |
| CMTI | >200 kV/µs - maintains signal integrity in high-dV/dt environments like 800 V SiC DC-link systems |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1 |
Pinout & Package
SI82F99ECE-IS3R uses a wide-body 14-pin SOIC (WB SOIC-14) package with creepage-enhanced layout for reinforced insulation. Pinout matches Figure 8 (Si82F99x High-Side/Low-Side with EN input) in Skyworks Preliminary Datasheet 206821A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input power supply | Supplies isolated digital side; 12 V UVLO ensures robust startup in automotive 12 V rail systems |
| GNDI | Logic input ground | Reference for CMOS-compatible PWM, EN, SPD±, DT inputs; galvanically separated from power grounds |
| PWM | Single-input control signal | Drives complementary VOA/VOB outputs; eliminates need for external logic to generate anti-phase signals |
| EN | Active-high enable | Unconditionally forces VOA/VOB low when deasserted - critical for safe shutdown in fault conditions |
| DT | Dead time programming input | Resistor-to-GND sets dead time (tDT = 1.73 × RDT + 5.74 ns); connection to VDDI disables dead time for dual-driver mode |
| SPD+ | Sourcing current control | Analog input setting one of eight current levels (SPD1–SPD7) for VOA/VOB turn-on; enables dynamic slew rate tuning |
| SPD− | Sinking current control | Analog input setting one of eight current levels for VOA/VOB turn-off; activates Miller clamp when VOA/B falls below ~1.9 V |
| VDDA | High-side gate driver supply | Independent 5–30 V rail for upper switch; monitored by dedicated 12 V UVLO for fail-safe operation |
| GNDA | High-side gate driver ground | Return path for high-side output; must be routed separately from GNDB to maintain isolation integrity |
| VDDB | Low-side gate driver supply | Independent 5–30 V rail for lower switch; UVLO independent of VDDA allows asymmetric power sequencing |
| GNDB | Low-side gate driver ground | Return path for low-side output; referenced to system power ground but isolated from GNDI |
| VOA | High-side gate driver output | Current-source output with integrated Miller clamp; connects directly to SiC/GaN gate without series resistor |
| VOB | Low-side gate driver output | Current-source output mirroring VOA behavior; complements VOA with programmable dead time |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete current levels for sourcing/sinking - replaces gate resistors and enables adaptive dV/dt control per switching event |
| Integrated Miller Clamp | Activates automatically when VOA/VOB falls below ~1.9 V - suppresses Miller-induced false turn-on in SiC/GaN half-bridges |
| Programmable Dead Time | Resistor-set delay (10–110 kΩ → 23–200 ns) between VOA/VOB transitions - prevents shoot-through without external logic |
| AEC-Q100 Qualified | Automotive-grade manufacturing flow with zero defects in HTOL, TC, and ESD testing - certified for EV onboard chargers and inverters |
| Reinforced Isolation | 6 kVRMS rating with 1500 VRMS working voltage and 10 kV bipolar surge - meets IEC 60747-17 and UL 1577 requirements |

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-IS3R | Universal configuration (dual independent inputs), no PWM input; same 6 kVRMS isolation and SelVCD™ | Better suited for synchronous buck or dual independent half-bridges where phase control is required | Select when separate VIA/VIB control is needed instead of single PWM; pinout differs (SOIC-14 NB vs WB) |
| UCC5870QDWJRQ1 | Texas Instruments part with 5.7 kVRMS isolation, 100 kV/µs CMTI, and integrated DESAT protection - no SelVCD™ or SPD± analog control | Preferred for IGBT-based industrial drives requiring desaturation detection and higher peak output current (10 A) | Choose when DESAT fault reporting and higher short-circuit robustness are prioritized over dynamic slew tuning |
Compared with SI82F99ECE-IS3R, Si8239BD-IS3R offers flexible input routing but lacks PWM simplicity, while UCC5870QDWJRQ1 adds DESAT protection at the cost of SelVCD™ programmability and lower CMTI - making SI82F99ECE-IS3R optimal for SiC/GaN half-bridge designs demanding adaptive dV/dt control and automotive qualification.

FAQ
What is the isolation voltage rating and safety certification status of SI82F99ECE-IS3R?
SI82F99ECE-IS3R is rated for 6 kVRMS isolation for 1 minute and carries pending certifications for UL 1577, CSA 62368-1 (reinforced insulation), VDE 60747-17, and CQC GB4943.1. Its 1500 VRMS working voltage and 10 kV bipolar surge capability make it suitable for automotive and industrial applications requiring reinforced insulation per IEC 60747-17. The device meets AEC-Q100 Grade 1 requirements for automotive use.
Does SI82F99ECE-IS3R support dynamic gate current adjustment during operation?
Yes, SI82F99ECE-IS3R supports dynamic speed control via its SPD+ and SPD− pins. Applying a voltage source (within specified min/max bounds per SPD level) instead of fixed resistors enables real-time reconfiguration of sourcing and sinking current levels. The Speed Update Delay (tSUD) determines response time, and the Miller clamp remains fully functional regardless of SPD setting - ensuring consistent turn-off behavior across all eight current levels.
How does the dead time function work on SI82F99ECE-IS3R, and can it be disabled?
Dead time on SI82F99ECE-IS3R is programmed using an external resistor (10–110 kΩ) between DT and GNDI, yielding 23–200 ns typical delay. It enforces non-overlapping VOA/VOB transitions to prevent shoot-through. To disable dead time and overlap protection - converting SI82F99ECE-IS3R into a dual independent driver - connect DT directly to VDDI. This configuration is explicitly supported per datasheet Figure 8 and Section 4.5.
What UVLO thresholds are implemented in SI82F99ECE-IS3R, and how do they behave independently?
SI82F99ECE-IS3R features independent UVLO monitoring: VDDI has a 12 V threshold (typical), while VDDA and VDDB each have 12 V thresholds. If VDDI drops below UVLO, both outputs go low regardless of gate supply status. If only VDDA falls below UVLO, VOA is forced low while VOB continues normal operation if VDDB remains valid - enabling graceful degradation in asymmetric power loss scenarios common in automotive systems.
Can SI82F99ECE-IS3R drive GaN HEMTs without external gate resistors?
Yes, SI82F99ECE-IS3R is explicitly designed to drive GaN FETs without external gate resistors. Its SelVCD™ current-source architecture delivers tightly regulated sourcing/sinking current across temperature and process variation, and its integrated Miller clamp engages at ~1.9 V to suppress false turn-on. Skyworks confirms direct connection to GaN gate terminals - adding any gate resistor degrades Miller clamp effectiveness and increases switching losses.
