Product details
Overview
SI82E99ABC-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 FET control in automotive-grade power inverters and onboard chargers.
For engineers reviewing the SI82E99ABC-IS1R datasheet, SI82E99ABC-IS1R pinout, SI82E99ABC-IS1R application, or SI82E99ABC-IS1R equivalent, key selection considerations include its enable-input (EN) logic interface, programmable dead time via DT pin, UVLO thresholds (4/8/12/15 V options), CMTI >200 kV/μs, and AEC-Q100 qualification for automotive systems.
Technical Context
The SI82E99ABC-IS1R implements silicon-dioxide capacitive isolation with RF OOK modulation, delivering deterministic timing and fault-tolerant signal transfer between logic and gate domains. Its dual-channel architecture supports synchronous PWM input (single-pin control) with independent high-side/low-side outputs and integrated overlap protection.
It features voltage-mode drive with external gate resistor tuning, active shutdown clamps on unpowered outputs, thermal shutdown at TSD+ = 150 °C, and a dedicated EN pin that forces both VOA and VOB low within tDID ≤ 45 ns when deasserted - enabling fast system-level fault response in motor drives and DC-DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577, VDE 60747-17, reinforced insulation) |
| Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side switching edges |
| CMTI | >200 kV/μs - maintains signal integrity in high-dV/dt environments like SiC inverters |
| Output Drive | 6 A peak sourcing/sinking - directly drives high-capacitance SiC/GaN FET gates without external buffers |
| UVLO Thresholds | Configurable at 4 V, 8 V, 12 V, or 15 V - prevents erratic switching during brown-out conditions |
| Operating Temp | –40 to +125 °C - validated for under-hood automotive applications per AEC-Q100 Grade 1 |
| Dead Time Range | Programmable 0–500 ns via external RDT (10–110 kΩ) - eliminates shoot-through in half-bridge topologies |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage ≥8.3 mm and clearance ≥8.0 mm per IEC 60664-1; RoHS-compliant, halogen-free, and qualified to AEC-Q100 Rev G.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input supply | 3–20 V CMOS-compatible digital power rail; powers internal isolator and logic |
| GNDI | Logic input ground | Reference for all digital inputs (PWM, EN, DT); galvanically isolated from power side |
| PWM | Single-input control signal | Drives complementary VOA/VOB outputs - enables compact half-bridge control with one controller pin |
| EN | Active-high enable | Asserting EN = high enables normal operation; deasserting EN = low forces VOA/VOB low within 45 ns |
| DT | Dead time programming | Resistor-to-GND sets dead time; connecting to VDDI disables dead time and overlap protection |
| VDDA / GNDA | High-side gate driver supply | 5–30 V isolated supply for VOA output; supports bootstrap or isolated supply configurations |
| VDDB / GNDB | Low-side gate driver supply | 5–30 V supply for VOB output; referenced to power ground, not logic ground |
| VOA / VOB | Complementary gate outputs | Voltage-mode outputs with 6 A peak drive; include short-circuit clamp and shutdown clamp |
Key Features
| Feature | Design Value |
|---|---|
| Universal or High-Side/Low-Side pinout | SI82E99ABC-IS1R uses High-Side/Low-Side configuration with PWM input - optimized for half-bridge FET control |
| Voltage Mode Drive | Enables precise gate rise/fall time tuning via external RG, balancing switching speed, EMI, and overshoot |
| Overlap Protection | Hardware-enforced logic prevents simultaneous VOA/VOB high states - eliminates shoot-through without firmware |
| AEC-Q100 Qualified | Qualified to Grade 1 (–40 to +125 °C) with automotive-specific manufacturing flow and defectivity controls |
| No Unknown Output States | Defined VOA/VOB behavior across all supply/power-up/down sequences - 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 |
|---|---|---|---|
| SIL1225ED-IM | Single-channel, 4 A drive, 5 kVRMS isolation, no dead time programming pin | Lacks dual-channel integration and programmable overlap protection | Use only where single-channel isolation suffices and shoot-through risk is managed externally |
| UCC5390SCD | 6 A dual-channel, 5.7 kVRMS, but uses optocoupler-based isolation and lacks AEC-Q100 qualification | Lower CMTI (100 kV/μs), higher propagation delay variation over temperature | Acceptable for industrial non-automotive use; not suitable for ASIL-B/C systems requiring silicon isolation reliability |
Compared with SIL1225ED-IM and UCC5390SCD, SI82E99ABC-IS1R uniquely combines AEC-Q100 qualification, 6 kVRMS reinforced isolation, sub-5 ns skew, and hardware-enforced dead time - making it the only option qualified for automotive-grade half-bridge SiC/GaN control with functional safety requirements.

FAQ
What is the isolation voltage rating of the SI82E99ABC-IS1R?
The SI82E99ABC-IS1R has a certified 6 kVRMS isolation rating for one minute per UL 1577, VDE 60747-17, and CSA 62368-1 standards. This reinforced insulation supports 1500 VRMS working voltage and 10 kV bipolar surge capability, meeting safety requirements for automotive and industrial high-voltage systems.
Does the SI82E99ABC-IS1R support both high-side/low-side and universal configurations?
No - SI82E99ABC-IS1R is specifically configured as a high-side/low-side driver with a single PWM input. The "99" suffix in the part number denotes this topology. Universal configuration (dual independent inputs VIA/VIB) is implemented in SI82E89x variants, not SI82E99ABC-IS1R.
How is dead time programmed on the SI82E99ABC-IS1R?
Dead time 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 0–500 ns per Equation 1 (tDT = 1.73 × RDT + 5.74). Connecting DT to VDDI disables dead time insertion and overlap protection, allowing dual-driver operation.
What UVLO thresholds are available on the SI82E99ABC-IS1R?
The SI82E99ABC-IS1R offers factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, VDDA, and VDDB supplies. These thresholds are fixed per device variant and selected at order time - the "ABC" suffix indicates the specific UVLO option; full details are in Skyworks' Ordering Guide (page 51 of DS206857C).
Is the SI82E99ABC-IS1R qualified for automotive applications?
Yes - SI82E99ABC-IS1R is AEC-Q100 qualified (Grade 1, –40 to +125 °C) and manufactured using automotive-specific process flows. It carries reinforced insulation certifications (UL, VDE, CSA, CQC) required for ASIL-B systems and is widely deployed in automotive onboard chargers and traction inverters.
