Product details
Overview
SI82F99EEC-IS1R from Skyworks Solutions is a high-voltage, dual-channel isolated gate driver in High-Side/Low-Side configuration with enable (EN) input, supporting SiC and GaN FETs in half-bridge topologies. It delivers 6 kVRMS isolation, <5 ns channel-to-channel skew, 200 kV/μs CMTI, and Selectable Variable Current Drive (SelVCD™) across eight sourcing/sinking levels. Used in onboard chargers and motor drives where shoot-through prevention and Miller clamping are critical.
For engineers reviewing the SI82F99EEC-IS1R datasheet, SI82F99EEC-IS1R pinout, SI82F99EEC-IS1R application, or SI82F99EEC-IS1R equivalent, this page provides verified functional identity, validated pin mapping for WB SOIC-14, confirmed SelVCD™ current control behavior, UVLO thresholds (12 V), and direct alternative options for half-bridge gate driving with integrated dead time and Miller clamp.
Technical Context
The SI82F99EEC-IS1R implements differential capacitive isolation using silicon dioxide barriers, enabling reinforced insulation and high noise immunity. Its PWM-input architecture routes a single logic signal to both channels while enforcing programmable dead time via external resistor on DT pin-critical for preventing shoot-through in half-bridge power stages.
It integrates a Miller clamp that activates when VOA or VOB falls below VMCTA/B (~1.9 V), forcing SPD– to maximum sinking level (SPD7–) during turn-off transitions. The device operates as a precision current source-not voltage source-with output current tightly regulated (±10%) over temperature and process variation for its 12 V UVLO variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for 1 minute - certified reinforced insulation per UL 1577, VDE 60747-17, and CSA 62368-1. |
| Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate drive edges. |
| CMTI | >200 kV/μs - rejects fast common-mode transients in high-dv/dt power converter environments. |
| UVLO Threshold | 12 V (VDDA/B) - prevents erroneous switching during brown-out; exits UVLO at 12.3 V, enters at 11.7 V. |
| SelVCD™ Levels | 8 discrete sourcing/sinking current settings - eliminates need for external gate resistors and enables dynamic speed control. |
| Working Voltage | 1500 VRMS - continuous operating voltage rating under reinforced insulation conditions. |
| Temperature Range | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for automotive power electronics. |
Pinout & Package
SI82F99EEC-IS1R uses a wide-body 14-pin SOIC (WB SOIC-14) package with creepage-enhanced layout for reinforced isolation. Pin 1 is VIA; pins 12 and 13 are NC; all isolation barriers are internal to the die stack-no external isolation components required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Logic input terminal | Not used in SI82F99x; reserved for Universal configuration variants - left unconnected. |
| PWM | Single logic input | Drives both VOA and VOB in complementary mode; high = VOA high / VOB low. |
| EN | Active-high enable | Asserting EN = high enables normal operation; deasserting forces VOA/VOB low unconditionally. |
| DT | Dead time programming | Resistor to GND sets dead time (10–110 kΩ → ~10–120 ns); connect to VDDI to disable dead time. |
| SPD+ | Sourcing current control | Resistor to GND selects one of eight turn-on current levels (SPD1–SPD8); determines gate charge rate. |
| SPD− | Sinking current control | Resistor to GND selects one of eight turn-off current levels; enables active Miller clamping at SPD7−. |
| VDDA / GNDA | High-side gate supply | Provides 5–30 V power to high-side driver stage; GNDA is isolated ground reference. |
| VDDB / GNDB | Low-side gate supply | Provides 5–30 V power to low-side driver stage; GNDB is isolated ground reference. |
| VOA / VOB | Gate drive outputs | Current-source outputs with integrated Miller clamp; directly connect to MOSFET/IGBT/SiC FET gates. |
| VDDI / GNDI | Input logic supply | 3–20 V CMOS-compatible supply; powers isolated input side and enables deglitch filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels set via SPD+/SPD− resistors - replaces gate resistors and enables adaptive switching speed. |
| Integrated Miller Clamp | Activates automatically when VOA/VOB falls below VMCTA/B (~1.9 V) - suppresses Miller-induced false turn-on without external components. |
| Programmable Dead Time | Resistor-controlled DT pin sets delay between VOA/VOB transitions (10–110 kΩ → ~10–120 ns) - prevents shoot-through in half-bridge circuits. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C ambient) - validated for automotive onboard chargers, traction inverters, and DC-DC converters. |
| High-Voltage Input Tolerance | CMOS inputs withstand up to 20 V with deglitch filter option - compatible with industrial PLCs and microcontrollers without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge isolated gate driving applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs SI8239ED-IS1R | Same Si82Fx family, but Universal configuration with VIA/VIB inputs and DIS pin instead of PWM/EN; no dead time overlap protection enabled by default. | Better suited for dual independent gate driving (e.g., full-bridge topologies), not half-bridge with enforced dead time. | Select SI8239ED-IS1R only if independent channel control is required and dead time must be implemented externally. |
| TI UCC5350MCDWVR | 3.3–15 V input, 5–30 V output, 5 kVRMS isolation, 100 kV/μs CMTI; no SelVCD™ or integrated Miller clamp - requires external gate resistors. | Lower isolation rating and missing Miller clamp reduce robustness in high-dv/dt SiC/GaN applications. | Choose UCC5350MCDWVR only for cost-sensitive, lower-performance 650 V IGBT designs where Miller immunity is less critical. |
Compared with SI82F99EEC-IS1R, SI8239ED-IS1R offers flexible input routing but lacks built-in dead time enforcement, while UCC5350MCDWVR trades isolation strength and Miller protection for lower cost and simpler biasing - neither matches SI82F99EEC-IS1R's combination of 6 kVRMS, <5 ns skew, and SelVCD™-enabled resistorless gate control.

FAQ
What is the isolation rating and safety certification status of SI82F99EEC-IS1R?
SI82F99EEC-IS1R 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 rating support compliance with IEC 62368-1 and ISO 6469 for automotive and industrial systems. All certifications apply directly to the SI82F99EEC-IS1R device variant.
Does SI82F99EEC-IS1R support both SiC and GaN FETs, and how does SelVCD™ benefit them?
Yes, SI82F99EEC-IS1R is explicitly rated for driving SiC MOSFETs and GaN HEMTs. SelVCD™ provides eight discrete sourcing/sinking current levels via SPD+/SPD− resistors - enabling precise control of gate charge/discharge rates without external resistors. This minimizes switching losses, suppresses gate ringing, and allows dynamic adaptation to different load conditions while maintaining tight current regulation (±10%) across temperature and process variation.
How is dead time programmed on SI82F99EEC-IS1R, and what is the range?
Dead time on SI82F99EEC-IS1R is programmed using an external resistor (RDT) from DT pin to GNDI. With RDT = 10–110 kΩ, typical dead time ranges from ~10 ns to ~120 ns, calculated as tDT = 1.73 × RDT + 5.74 (ns). Connecting DT to VDDI disables dead time insertion entirely, converting SI82F99EEC-IS1R into a dual independent driver - though this is not the intended use case for this part number.
What is the function of the Miller clamp in SI82F99EEC-IS1R, and when does it activate?
The Miller clamp in SI82F99EEC-IS1R activates automatically when VOA or VOB falls below VMCTA/B (~1.9 V) during turn-off transitions. It forces the sinking current to SPD7– level to rapidly discharge the Miller capacitance and prevent false turn-on of the power switch. The clamp remains engaged until the next rising edge at VOA/VOB and requires no external components - a key advantage over traditional gate drivers needing discrete clamp diodes or resistors.
Is SI82F99EEC-IS1R pin-compatible with other Si82Fx variants like SI82F39 or SI82F89?
No, SI82F99EEC-IS1R is not pin-compatible with SI82F39 or SI82F89 variants. It belongs to the Si82F99x subfamily with PWM/EN inputs and High-Side/Low-Side configuration in WB SOIC-14. SI82F39x uses VIA/VIB inputs and EN, while SI82F89x uses PWM and DIS - each has distinct pinouts and truth table behavior. Substituting without board revision will result in incorrect logic operation or failure to drive.
