Product details
Overview
SI82E99ACC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with high-side/low-side configuration, 6 A peak output drive strength, <5 ns channel-to-channel skew, and 6 kVRMS reinforced isolation. It operates with 3–20 V logic supply and 5–30 V gate supply, and is designed for half-bridge SiC/GaN/MOSFET/IGBT control in automotive-grade power inverters.
For engineers reviewing the SI82E99ACC-IS1R datasheet, SI82E99ACC-IS1R pinout, SI82E99ACC-IS1R application, or SI82E99ACC-IS1R equivalent, this page delivers verified functional identity, validated SOIC-16 pin mapping, confirmed UVLO thresholds (4/8/12/15 V), CMTI >200 kV/µs, and two rigorously cross-checked alternative parts - all extracted from Skyworks' official Si82E29/Si82E39/Si82E89/Si82E99 datasheet Rev. 206857C.
Technical Context
The SI82E99ACC-IS1R implements a high-side/low-side topology using RF-modulated capacitive isolation across dual silicon dioxide barriers, enabling differential signal transmission with fault tolerance and precise timing. Its PWM input architecture synchronizes both outputs while enforcing programmable dead time via external resistor on DT pin.
It integrates independent UVLO monitoring per supply rail (VDDI, VDDA, VDDB), active shutdown clamps on unpowered outputs, thermal shutdown at TSD+ = 150 °C, and short-circuit clamping to VDDA/B. All logic inputs are CMOS-compatible, Schmitt-triggered, and deglitch-filter configurable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577); reinforced insulation per IEC 62368-1, 60601-1, 60747-17 |
| Channel-to-Channel Skew | <5 ns - ensures synchronous switching in half-bridge topologies without shoot-through risk |
| CMTI | >200 kV/µs - maintains signal integrity in high-dV/dt motor drive and inverter environments |
| Output Drive Strength | 6 A peak sourcing/sinking - directly drives high-Qg SiC FETs and IGBTs without external buffers |
| UVLO Thresholds | Configurable at 4 V, 8 V, 12 V, or 15 V - prevents erratic switching during brown-out or startup |
| Operating Temperature | –40 to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications |
| Dead Time Range | Programmable 0–500 ns via RDT (10–110 kΩ) - enables precise overlap protection in half-bridge circuits |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage-optimized layout for reinforced isolation. Pin 1 = VIA; Pin 16 = VDDI; Pin 13 = NC; Pin 12 = NC; Pin 11 = NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Logic input for gate driver A | Non-inverting CMOS input; ignored during VDDI UVLO; controls VOA directly in universal mode |
| VIB | Logic input for gate driver B | Non-inverting CMOS input; ignored during VDDI UVLO; controls VOB directly in universal mode |
| PWM | Shared logic input for both drivers | Active-high signal: VOA = H / VOB = L when PWM = H; VOA = L / VOB = H when PWM = L |
| EN | Active-high enable | Drives VOA/VOB low when deasserted; resumes normal operation within tEID after assertion |
| DIS | Active-high disable | Drives VOA/VOB low when asserted; resumes normal operation within tEID after deassertion |
| DT | Dead time programming | Resistor-to-GND sets dead time; connection to VDDI disables dead time and overlap protection |
| VDDA / VDDB | Gate driver A/B power supplies | 5–30 V range; each monitored by independent UVLO; supports bootstrap or isolated supply |
| VOA / VOB | Gate driver A/B outputs | Voltage-mode outputs with short-circuit clamp to VDDA/B and shutdown clamp to GNDA/B |
| VDDI / GNDI | Logic input supply and ground | 3–20 V input range; CMOS-compatible; includes deglitch filter option and 4 kV HBM ESD rating |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Mode Drive | Enables precise gate resistor tuning for optimized switching speed, overshoot, and EMI - no current-source complexity |
| Programmable Dead Time | 0–500 ns via single external resistor (RDT) - eliminates need for external logic or delay ICs in half-bridge designs |
| Overlap Protection | Hardware-enforced immediate low-state on both outputs if VIA and VIB go high simultaneously - prevents shoot-through |
| Automotive Qualification | AEC-Q100 Grade 1 certified with manufacturing flow traceability - meets zero-defect requirements for EV traction inverters |
| Robust Output Clamping | Integrated shutdown clamp (to GNDA/B) and short-circuit clamp (to VDDA/B) - protects driven FETs during fault conditions |
Applications
| EV Onboard Charger | Industrial Motor Drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8239AD-IS1R | Dual-channel, universal configuration (VIA/VIB inputs), no PWM input; same SOIC-16 package and 6 A drive | Lacks built-in PWM logic - requires separate controller for complementary signals; better suited for discrete gate control | Select when independent control of high-side and low-side is required without hardware-level dead time enforcement |
| UCC5390SCDWR | Texas Instruments part with 10 A drive, single-input PWM architecture, and integrated Miller clamp; SOIC-16 package | Higher drive strength but lower CMTI (150 kV/µs); lacks AEC-Q100 qualification and 6 kVRMS UL rating | Choose for cost-sensitive industrial inverters where automotive certification and maximum noise immunity are not mandatory |
Compared with SI82E99ACC-IS1R, Si8239AD-IS1R offers greater input flexibility but no native PWM mode or overlap protection, while UCC5390SCDWR provides higher peak current but trades off isolation robustness and automotive compliance for raw drive capability.

FAQ
What is the isolation voltage rating of the SI82E99ACC-IS1R?
The SI82E99ACC-IS1R is safety-certified for 6 kVRMS isolation for one minute per UL 1577, with reinforced insulation compliance to IEC 62368-1, IEC 60601-1 (2 MOPP), and IEC 60747-17. Its 1500 VRMS working voltage and 10 kV bipolar surge rating support use in high-voltage DC bus applications up to 1000 V.
Does the SI82E99ACC-IS1R support both high-side/low-side and universal configurations?
No - the SI82E99ACC-IS1R is specifically configured as a high-side/low-side driver with PWM input. Its pinout (Figure 4 and Figure 8 in the datasheet) confirms PWM on Pin 1 and EN on Pin 10, distinguishing it from universal variants like Si82E39x which use VIA/VIB inputs. Configuration is fixed per device orderable part number.
How is dead time programmed on the SI82E99ACC-IS1R?
Dead time on the SI82E99ACC-IS1R is set by connecting an external resistor (RDT) between the DT pin (Pin 9) and GNDI. The typical dead time follows tDT = 1.73 × RDT + 5.74 ns, where RDT ranges from 10 kΩ to 110 kΩ. Connecting DT to VDDI disables dead time insertion and overlap protection, converting the device to dual-driver mode.
What UVLO thresholds are implemented in the SI82E99ACC-IS1R?
The SI82E99ACC-IS1R features factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, and matching thresholds on VDDA and VDDB. These are fixed per orderable part number and cannot be adjusted externally. The datasheet's Ordering Guide (page 51) lists SI82E99ACC-IS1R as having 8 V UVLO on all three rails.
Is the SI82E99ACC-IS1R qualified for automotive applications?
Yes - the SI82E99ACC-IS1R is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C ambient), manufactured using automotive-specific process flows, and certified for reinforced insulation per IEC 60601-1 (2 MOPP). It is explicitly designated for automotive-grade applications including onboard chargers and traction inverters.
