Product details
Overview
SI8286ED-ASR from Skyworks is an automotive-grade, isolated high-current gate driver with integrated DC-DC converter, designed for SiC FETs and IGBTs in traction inverters and on-board chargers. It delivers 4 A peak sink/source drive current, supports 15 V UVLO threshold, features desaturation detection with <1 µs fault response, and provides reinforced isolation rated at 5.0 kVrms per UL1577.
For engineers reviewing the SI8286ED-ASR datasheet, SI8286ED-ASR pinout, SI8286ED-ASR application, or SI8286ED-ASR equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive qualification (AEC-Q100), real-world motor control use cases, and two rigorously cross-checked alternative parts - all grounded in Skyworks' official Si828x family documentation.
Technical Context
The SI8286ED-ASR implements RF-based digital isolation with 125 kV/µs CMTI, enabling robust noise immunity in high-dV/dt power systems. Its dual-output architecture separates VH (gate pull-up) and VL (gate pull-down) to support independent gate resistor tuning for precise SiC FET switching control.
It integrates a feedback-controlled DC-DC controller with external power switch support, programmable frequency, soft-start, and shutdown functionality - all configured via SH/FC, SS, and RSTb pins. The device includes active Miller clamp, DESAT sensing with 7 V threshold and 220 mV hysteresis, and push-pull RDY output indicating dual-side power readiness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms (UL1577), enabling reinforced insulation in 800 V EV traction systems. |
| Peak Output Current | ±4 A (sink/source), sufficient to drive high-Qg SiC FETs without external boost stages. |
| UVLO Threshold | 15 V (VDDB–VMID), optimized for stable SiC FET turn-on with margin above 12 V gate drive rails. |
| DESAT Response Time | <1 µs, enabling ultra-fast short-circuit protection before destructive energy accumulates. |
| CMTI | 125 kV/µs, ensuring reliable operation during fast-switching transients in motor drives. |
| DC-DC Control | External switch configuration with programmable frequency, supporting >20 V input rails common in automotive 12 V/48 V systems. |
| Operating Temp | –40 °C to +125 °C, qualified per AEC-Q100 Grade 1 for under-hood automotive environments. |
Pinout & Package
SI8286ED-ASR is housed in a 24-pin wide-body SOIC package (WB SOIC-24) with creepage/clearance compliant with reinforced insulation requirements for automotive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN− | Complementary digital input pair | Supports active-high or active-low logic control; enables differential noise rejection in EMI-heavy motor control PCBs. |
| VH, VL | Separate gate drive outputs | Allow independent gate resistor selection for optimizing SiC FET rise/fall times and dV/dt control. |
| DSAT | Desaturation sense input | Monitors VDS/VCE via external RDSAT/DDSAT; triggers soft shutdown if voltage exceeds 7 V within blanking window. |
| CLMP | Miller clamp control terminal | Actively clamps gate to VMID during high dV/dt events to prevent parasitic turn-on in half-bridge topologies. |
| RSTb | Active-low reset input | Clears DESAT fault latching; requires ≥350 ns low pulse to restore driver operation after fault recovery. |
| RDY | Power-ready status output | Push-pull signal indicates both VDDA and VDDB are above UVLO thresholds - critical for safe startup sequencing. |
| /FLT | Open-drain fault indicator | Drives low on DESAT or UVLO fault; supports wired-OR fault bus across multiple drivers in multi-phase inverters. |
| SH/FC, SS | DC-DC control inputs | Enable shutdown, frequency adjustment, and soft-start - essential for EMI management and inrush current limiting. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated DESAT protection | 7 V threshold with 220 mV hysteresis and configurable blanking time - eliminates need for discrete fault detection circuitry. |
| Soft shutdown | Controlled gate discharge via weak pull-down path reduces dV/dt stress during fault events, preventing secondary breakdown. |
| Reinforced isolation | 5.0 kVrms withstand voltage certified to UL1577, CSA/IEC/VDE EN 62368-1 - meets ASIL-D system-level safety requirements. |
| Automotive qualification | AEC-Q100 Grade 1, PPAP documentation support, IMDS/CAMDS compliance - validated for production deployment in HEV/EV powertrain. |
| DC-DC converter flexibility | External switch topology accepts up to 24 V input, enabling direct connection to automotive 12 V rail without pre-regulation. |
Applications
| Electric Vehicle Traction Inverter | On-Board Charger (OBC) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8284ED-ASR | Same 24-pin WB SOIC package, identical 15 V UVLO and 5 kVrms isolation, but adds programmable DC-DC frequency and shutdown control not present in SI8286ED-ASR. | Preferred where EMI optimization via frequency dithering or controlled power-down sequencing is required. | Select Si8284ED-ASR when full DC-DC configurability is needed; SI8286ED-ASR is optimal for cost-sensitive, fixed-frequency OBC designs. |
| UCC5870QDWJRQ1 | Texas Instruments part with 5.7 kVrms isolation, 10 A peak output, and integrated isolated DC-DC, but uses different pinout and lacks dedicated CLMP pin. | Better suited for high-current traction inverters requiring >6 A drive, but demands PCB redesign due to non-compatible layout. | Choose UCC5870QDWJRQ1 only when higher drive strength justifies layout change; SI8286ED-ASR maintains drop-in compatibility in existing Si828x footprints. |
Compared with Si8284ED-ASR, SI8286ED-ASR offers identical core protection and isolation but omits programmable DC-DC controls - simplifying design and reducing system-level validation effort. Against UCC5870QDWJRQ1, it trades peak current for pinout compatibility and lower EMI sensitivity, making it preferable for space-constrained automotive modules where layout reuse is critical.

FAQ
What is the isolation voltage rating of the SI8286ED-ASR?
The SI8286ED-ASR provides 5.0 kVrms reinforced isolation per UL1577, validated for 1 minute. This rating is certified across CSA, VDE, and CQC standards (IEC/EN 62368-1, GB4943.1-2011), making SI8286ED-ASR suitable for functional safety applications in 800 V battery systems where creepage and clearance must meet ASIL-D requirements.
Does the SI8286ED-ASR support SiC FETs with 15 V gate drive?
Yes, the SI8286ED-ASR features a 15 V UVLO threshold (VDDB–VMID), explicitly designed for reliable turn-on of SiC FETs requiring gate voltages ≥12 V. Its ±4 A peak output current and integrated Miller clamp ensure robust gate control under high dV/dt conditions typical in SiC-based inverters - a key capability confirmed in Skyworks' Si828x family datasheet Section 4.3.
How does the DESAT protection work in the SI8286ED-ASR?
The SI8286ED-ASR monitors VDS/VCE via its DSAT pin using an internal 7 V comparator with 220 mV hysteresis. When the sensed voltage fails to fall below threshold within the blanking window (set by external CBL), it triggers soft shutdown in <1 µs and asserts /FLT. This behavior is documented in Figure 3.4 and Section 3.1.4 of the official datasheet, with no reliance on external comparators or timers.
Is the SI8286ED-ASR pin-compatible with other Si828x variants?
SI8286ED-ASR shares the same 24-pin wide-body SOIC footprint and pinout as Si8283/84 variants (e.g., Si8284ED-ASR), including identical VH, VL, DSAT, CLMP, RSTb, and /FLT assignments. Pin compatibility is confirmed in Tables 1.1 and 5.1 of the Skyworks datasheet, enabling direct substitution where DC-DC control feature differences are acceptable.
What automotive qualifications does the SI8286ED-ASR hold?
The SI8286ED-ASR is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C), manufactured using automotive-specific process flows, and supported with PPAP documentation, IMDS, and CAMDS listings. These qualifications are explicitly stated in the "Automotive Grade" section and Table 1.1 of the Si828x datasheet, confirming its readiness for production in HEV/EV powertrain systems.
