Product details
Overview
SI82F89ACC-IS1R from Skyworks Solutions is a high-voltage isolated dual-channel 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™) supporting eight sourcing/sinking current levels. It drives SiC/GaN FETs and IGBTs in half-bridge motor inverters and onboard chargers.
For engineers reviewing the SI82F89ACC-IS1R datasheet, SI82F89ACC-IS1R pinout, SI82F89ACC-IS1R application, or SI82F89ACC-IS1R equivalent, key selection criteria include its DIS-controlled shutdown behavior, SPD±-programmable current drive without external gate resistors, integrated Miller clamp, 200 kV/µs CMTI, and AEC-Q100 qualification for automotive power systems.
Technical Context
The SI82F89ACC-IS1R implements differential capacitive isolation using silicon dioxide barriers, enabling RF-modulated signal transmission with OOK encoding for precise timing and fault tolerance. Its dual-channel architecture supports half-bridge operation via dedicated PWM input and programmable dead time (DT) control.
It features independent UVLO monitoring per supply rail (VDDI, VDDA, VDDB), CMOS-compatible Schmitt-triggered inputs with deglitch filtering option, and analog SPD± pins that configure sourcing/sinking current as a precision current source-maintaining ±10% tolerance over temperature and process for 8 V/12 V/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 - enables precise synchronous switching in high-frequency half-bridge topologies |
| CMTI | >200 kV/µs - ensures robust noise immunity in fast-switching SiC/GaN power stages |
| Input Supply Range | 3 V to 20 V - compatible with 3.3 V, 5 V, and 12 V logic controllers without level shifting |
| Gate Drive Supply | 5 V to 30 V - supports wide-range gate bias for IGBTs, SiC MOSFETs, and GaN HEMTs |
| Operating Temp | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| UVLO Thresholds | 4 V / 8 V / 12 V / 15 V - selectable per variant; SI82F89ACC-IS1R uses 12 V UVLO on VDDA/VDDB |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with 1.27 mm pitch and creepage ≥8.3 mm. Pin 1 marked with dot; pins 12 and 13 are NC (no connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for Channel A | Accepts CMOS-level PWM or control signal; not used in SI82F89x (PWM-only interface) |
| PWM | Single-input control for both channels | Drives VOA high / VOB low when high; VOA low / VOB high when low - native half-bridge mode |
| DIS | Active-high disable input | Forces VOA and VOB low unconditionally; overrides all logic states during fault or shutdown |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~17–200 ns); connect to VDDI to disable dead time |
| SPD+ | Sourcing current control (turn-on) | Configures output sourcing current across 8 levels; eliminates need for external turn-on gate resistor |
| SPD− | Sinking current control (turn-off) | Configures output sinking current across 8 levels; enables dynamic Miller clamping at VOH→VOL transition |
| VOA / VOB | Isolated gate driver outputs | Current-source outputs with integrated Miller clamp; directly connect to power switch gate without series R |
| VDDI / GNDI | Logic-side supply and ground | 3–20 V input domain; powers isolation barrier and digital interface; includes UVLO monitoring |
| VDDA / GNDA / VDDB / GNDB | Isolated output-side supplies | Dual independent 5–30 V rails; each monitored by dedicated UVLO; enable asymmetric gate bias |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels set via SPD± resistors or voltage sources - replaces gate resistors and enables adaptive switching speed |
| Integrated Miller Clamp | Engages automatically when VOA/VOB falls below VMCTA/B (~2 V); maximizes sinking current (SPD7−) to suppress Miller-induced turn-on during dV/dt events |
| Programmable Dead Time | Resistor-programmed delay (17–200 ns typical) between VOA/VOB transitions - prevents shoot-through in half-bridge configurations |
| High-Voltage Input Tolerance | CMOS/Schmitt inputs withstand up to 20 V; SPD± pins include HV clamp protecting internal 1.9 V LDO - enables direct MCU interface without buffering |
| Defined Output States | No floating or undefined outputs: UVLO, DIS assertion, or power loss forces VOA/VOB low via active clamp - critical for functional safety compliance |

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, isolation, and SelVCD™ capability | Preferred where active-high enable logic aligns with system controller architecture; requires inverted fault signaling vs. DIS-driven shutdown | Select Si8239BD-IS1R if system uses positive-enable control; otherwise SI82F89ACC-IS1R provides direct fault-asserted shutdown. |
| UCC5390SCDR | Texas Instruments part with 5 kVRMS isolation, single-input PWM interface, and 100 kV/µs CMTI - lower isolation rating and no SPD± current programming | Suitable for cost-sensitive industrial inverters where 6 kVRMS certification is not required and fixed gate drive suffices | Choose UCC5390SCDR only for non-automotive, non-safety-critical designs lacking need for AEC-Q100 or programmable current drive. |
Compared with Si8239BD-IS1R, SI82F89ACC-IS1R offers faster fault response via DIS assertion rather than EN deassertion; versus UCC5390SCDR, it delivers higher isolation, superior CMTI, and full SelVCD™ flexibility essential for SiC/GaN optimization.

FAQ
What is the isolation rating and safety certification status of SI82F89ACC-IS1R?
The SI82F89ACC-IS1R provides 6 kVRMS reinforced isolation rated for 1 minute per UL 1577, with pending certifications to VDE 60747-17, CSA 62368-1, and GB4943.1. It meets AEC-Q100 Grade 1 requirements and supports 1500 VRMS working voltage and 10 kV bipolar surge immunity - making it suitable for automotive and industrial safety-critical applications.
How does the DIS pin function in SI82F89ACC-IS1R compared to EN on other Si82Fx variants?
In SI82F89ACC-IS1R, the DIS pin is active-high: asserting DIS (logic high) unconditionally forces both VOA and VOB low within tDID, overriding all input states and UVLO conditions. This differs from EN-based variants like Si8239BD-IS1R, where EN must be held high for normal operation - giving SI82F89ACC-IS1R faster, more deterministic fault shutdown behavior ideal for automotive fail-safe architectures.
Can SI82F89ACC-IS1R drive both SiC MOSFETs and IGBTs effectively?
Yes, SI82F89ACC-IS1R is explicitly validated for SiC FETs, GaN HEMTs, and IGBTs. Its 5–30 V gate supply range, programmable SelVCD™ current (up to ±10 A typical), integrated Miller clamp, and 200 kV/µs CMTI ensure robust turn-on/turn-off control across wide VGS/VEE requirements and high dV/dt environments common to all three device types.
What is the role of SPD+ and SPD− pins, and how are they configured?
The SPD+ and SPD− pins on SI82F89ACC-IS1R set sourcing and sinking current levels across eight discrete steps using resistor dividers to GNDI. Each pin sources ISPD± current; the measured voltage determines the output current. Static configuration uses 1% resistors; dynamic control applies voltage sources within specified bounds - eliminating external gate resistors and enabling real-time switching speed adaptation.
Does SI82F89ACC-IS1R require external gate resistors when driving power switches?
No, SI82F89ACC-IS1R does not require external gate resistors due to its SelVCD™ current-source architecture and integrated Miller clamp. Adding gate resistors degrades Miller clamp effectiveness, increases switching losses, and risks thermal overload. The driver delivers controlled current directly to the gate, with SPD± pins enabling precise tuning of turn-on/turn-off strength without discrete components.
