Product details
Overview
SI82E89ACE-IS3R from Skyworks Solutions is a dual-channel isolated gate driver with high-side/low-side configuration, 6 A peak output current per channel, <5 ns channel-to-channel skew, and 6 kVRMS reinforced isolation. It drives SiC/GaN MOSFETs and IGBTs in half-bridge topologies for onboard chargers and motor inverters.
For engineers reviewing the SI82E89ACE-IS3R datasheet, SI82E89ACE-IS3R pinout, SI82E89ACE-IS3R application, or SI82E89ACE-IS3R equivalent, this page delivers verified functional identity, validated SOIC-16 pin mapping, confirmed dead-time programmability, CMTI >200 kV/µs performance, and automotive-grade AEC-Q100 qualification - all critical for high-reliability power stage design.
Technical Context
The SI82E89ACE-IS3R implements a PWM-input, high-side/low-side gate driver architecture using silicon-dioxide capacitive isolation with RF OOK modulation. It features independent UVLO on VDDI (4 V threshold), VDDA (8 V), and VDDB (8 V), plus integrated shutdown clamp and short-circuit clamp protection per output.
Its DT pin enables resistor-programmable dead time (10–110 kΩ → ~17–200 ns typical) with overlap protection that forces both outputs low during simultaneous high inputs - preventing shoot-through in half-bridge circuits without external logic.
Key Specifications

| Isolation Rating | 6 kVRMS for 1 minute (UL 1577), reinforced insulation per VDE 60747-17 & CSA 62368-1 |
| Output Drive Strength | 6 A peak sourcing/sinking per channel - supports fast switching of 1200 V SiC FETs with <50 ns rise/fall times |
| Channel-to-Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate signals |
| CMTI | >200 kV/µs - maintains signal integrity in noisy high-dV/dt environments like motor drives |
| Input Logic Type | PWM input (single control line) with CMOS-compatible Schmitt-triggered inputs - eliminates need for external level-shifting |

Narrow-body 16-pin SOIC package (SOIC-16 NB) with 1.27 mm pitch; creepage ≥8.3 mm, clearance ≥8.0 mm; RoHS-compliant, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 VOA | Gate driver A output | High-side gate drive output; includes short-circuit clamp to VDDA and shutdown clamp to GNDA |
| 4 GNDA | Gate driver A ground reference | Isolated ground for high-side circuit; must be tied to source of high-side FET |
| 5 VDDB | Gate driver B power supply | Supplies 5–30 V to low-side output stage; UVLO triggers at 8 V |
| 6 VOB | Gate driver B output | Low-side gate drive output; includes same clamping protections as VOA |

| 11 DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~17–200 ns); connect to VDDI to disable |
| 12 DIS | Active-high disable input | Drives VOA/VOB low unconditionally when asserted; overrides all other inputs |
| 13 NC | No connection | Internally unconnected; must remain floating or grounded per layout best practices |
| 14 NC | No connection | Internally unconnected; must remain floating or grounded per layout best practices |
| 15 NC | No connection | Internally unconnected; must remain floating or grounded per layout best practices |
| 16 PWM | Single PWM logic input | Drives VOA high / VOB low when high; VOA low / VOB high when low - native half-bridge control |
Key Features
| Feature | Design Value |
|---|---|
| High-Side/Low-Side Configuration | Native PWM-input topology eliminates need for external XOR logic or dual-input controllers |
| Programmable Dead Time | Resistor-adjustable delay (10–110 kΩ) ensures shoot-through prevention without fixed timing constraints |
| Voltage Mode Drive | Output behaves as controlled voltage source - gate resistor selection directly tunes dV/dt and EMI |
| Automotive Qualification | AEC-Q100 Grade 1 qualified - validated for 15-year lifetime in automotive powertrain and charging systems |
| Robust Isolation Architecture | Dual SO₂ capacitors with differential RF modulation - achieves 200 kV/µs CMTI and stable timing over temperature |
| Fail-Safe Output States | No undefined outputs: UVLO, power loss, or DIS assertion forces VOA/VOB low - prevents unintended FET turn-on |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si82E89AD-IS3R | Same SOIC-16 package and PWM-input architecture, but with 12 V VDDA/VDDB UVLO instead of 8 V | Better suited for systems with higher gate drive rail stability; less tolerant of transient dips below 10 V | Select when gate supply rails are tightly regulated above 10 V and shoot-through risk from UVLO misalignment is prioritized |
| UCC5390SCD | Texas Instruments part with 10 A peak drive, single 5–25 V supply, and integrated Miller clamp - no separate VDDA/VDDB | Lacks independent high-side/low-side UVLO; requires external bootstrap or isolated supplies for high-side operation | Choose for cost-sensitive industrial designs where 10 A drive and integrated clamping outweigh need for dual-rail flexibility |
Compared with SI82E89ACE-IS3R, Si82E89AD-IS3R offers tighter UVLO hysteresis for robust high-voltage gate rails, while UCC5390SCD trades dual-supply flexibility for higher peak current and integrated protection - making SI82E89ACE-IS3R optimal for automotive OBCs requiring AEC-Q100, dual-rail control, and field-proven 6 kVRMS isolation.

FAQ
What is the isolation architecture used in the SI82E89ACE-IS3R?
The SI82E89ACE-IS3R uses capacitive isolation based on dual silicon-dioxide (SiO₂) dielectric barriers with RF OOK modulation. This architecture provides 6 kVRMS one-minute isolation, 1500 VRMS working voltage, and >200 kV/µs common-mode transient immunity - outperforming optocouplers in timing stability and lifetime reliability. The SI82E89ACE-IS3R does not use transformers or magnetic coupling.
Does the SI82E89ACE-IS3R support both high-side and low-side gate driving in a single package?
Yes, the SI82E89ACE-IS3R integrates two fully isolated gate drivers in one SOIC-16 package: VOA drives the high-side switch (e.g., upper FET in a half-bridge), and VOB drives the low-side switch (e.g., lower FET). Each has independent power supplies (VDDA/GNDA and VDDB/GNDB), UVLO monitoring, and clamping protection - eliminating need for discrete isolators or level shifters.
How is dead time configured on the SI82E89ACE-IS3R?
Dead time on the SI82E89ACE-IS3R is set by connecting an external resistor (RDT) between the DT pin and GNDI. Values from 10 kΩ to 110 kΩ yield typical dead times of ~17 ns to ~200 ns. Connecting DT to VDDI disables dead time insertion and overlap protection, allowing dual independent gate drive operation. No internal DAC or register programming is required.
What safety certifications does the SI82E89ACE-IS3R hold?
The SI82E89ACE-IS3R is UL 1577 recognized (6000 VRMS, 1 min), VDE 60747-17 certified (reinforced insulation), CSA 62368-1 and 60601-1 compliant (2 MOPP), and CQC GB4943.1 approved - all confirming its suitability for medical, industrial, and automotive end-equipment requiring reinforced isolation barriers.
Is the SI82E89ACE-IS3R qualified for automotive applications?
Yes, the SI82E89ACE-IS3R is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C ambient), manufactured using automotive-specific process flows, and tested for low defectivity and long-term reliability. It is explicitly designated for automotive onboard chargers, traction inverters, and DC-DC converters where functional safety and extended lifetime are mandatory.
