Product details
Overview
SI82E39AGC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with 6 A peak output current, universal configuration (independent VIA/VIB inputs), and enable (EN) control logic. It delivers <5 ns channel-to-channel skew, 200 kV/µs CMTI, and 6 kVRMS reinforced isolation for driving SiC/GaN MOSFETs and IGBTs in high-frequency half-bridge inverters.
For engineers reviewing the SI82E39AGC-IS1R datasheet, SI82E39AGC-IS1R pinout, SI82E39AGC-IS1R application, or SI82E39AGC-IS1R equivalent, this page provides verified functional identity, validated SOIC-16 narrow-body package mapping, confirmed UVLO thresholds (4 V/8 V/12 V/15 V options), dead time programmability via external resistor, and real-world motor drive and onboard charger use cases.
Technical Context
The SI82E39AGC-IS1R implements capacitive silicon-dioxide isolation with differential RF-modulated OOK signaling across two independent channels, enabling precise timing control and fault tolerance. Its universal input architecture accepts separate non-inverting logic signals (VIA, VIB) and features active-high EN for synchronous enable/disable of both outputs.
It integrates independent undervoltage lockout on VDDI (logic supply), VDDA, and VDDB (gate supplies), plus programmable dead time via DT pin resistor (10–110 kΩ), overlap protection, thermal shutdown at 150 °C, and short-circuit clamping to VDDA/B. Output stage operates in voltage-mode drive with external gate resistors defining slew rate and peak current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for 1 minute - meets UL 1577, VDE 60747-17, and CSA 62368-1 reinforced insulation requirements. |
| Channel-to-Channel Skew | <5 ns - ensures synchronized switching in high-frequency half-bridge topologies without shoot-through risk. |
| CMTI | >200 kV/µs - maintains signal integrity in noisy high-dV/dt environments like SiC/GaN power stages. |
| Peak Output Current | 6 A sourcing/sinking - drives high-gate-charge wide-bandgap FETs with fast turn-on/turn-off transitions. |
| Input Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller logic levels without level-shifting. |
| Gate Supply Range | 5–30 V - supports bipolar (±15 V) or unipolar (12 V/15 V) gate bias for MOSFET/IGBT/SiC/GaN devices. |
| Operating Temperature | –40 to +125 °C - qualified per AEC-Q100 Grade 1 for automotive under-hood and industrial embedded use. |
Pinout & Package
Narrow-body 16-pin SOIC (SOIC-16 NB) package with creepage ≥8.3 mm and clearance ≥8.0 mm; RoHS-compliant, halogen-free, and qualified for automotive-grade reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for Channel A | Accepts CMOS-level PWM or control signal; enables independent high-side or low-side gate drive control. |
| VIB | Non-inverting logic input for Channel B | Provides fully asynchronous second channel input; allows universal dual-driver operation without shared PWM. |
| EN | Active-high enable input | Drives both VOA and VOB low when deasserted; enables system-level fault shutdown with <100 ns response. |
| DT | Dead time programming terminal | Resistor-to-GND sets dead time (10–110 kΩ → ~17–200 ns); connecting to VDDI disables dead time and overlap protection. |
| VDDA / GNDA | Channel A gate driver supply and ground | Independent 5–30 V power domain for high-side or low-side output stage; supports bootstrap or isolated supply. |
| VDDB / GNDB | Channel B gate driver supply and ground | Electrically isolated from VDDA/GNDA; enables floating high-side drive or independent low-side biasing. |
| VOA / VOB | High-current gate drive outputs | Voltage-mode outputs delivering ±6 A peak; designed for direct connection to FET gates via external RG. |
| VDDI / GNDI | Logic input supply and isolated ground | 3–20 V digital interface domain; galvanically separated from gate driver domains by SiO2 capacitors. |
Key Features
| Feature | Design Value |
|---|---|
| Universal input configuration | Separate VIA/VIB pins allow asymmetric control of high-side and low-side switches-no fixed PWM/COM topology required. |
| Voltage-mode gate drive | Output behaves as controlled voltage source; gate resistor selection directly sets dV/dt, EMI, and overshoot-no current-source complexity. |
| Programmable dead time & overlap protection | Hardware-enforced dead time prevents shoot-through; automatic low-output clamp during simultaneous high inputs eliminates software dependency. |
| Multiple UVLO thresholds | Selectable 4 V / 8 V / 12 V / 15 V logic and gate supply UVLO levels ensure robust startup/shutdown sequencing in multi-rail systems. |
| Automotive-grade qualification | AEC-Q100 Grade 1 certified with full automotive process flow-validated for 15-year lifetime in harsh thermal and vibration environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs Si8239AD-IS1R | Same Si82Ex family, identical SOIC-16 NB package and pinout; differs only in deglitch filter setting (100 ns vs. 50 ns). | No functional impact on motor drive or OBC use; same timing, isolation, and drive strength-only noise immunity profile varies. | Select Si8239AD-IS1R if system EMI environment demands higher input noise rejection; otherwise SI82E39AGC-IS1R is drop-in compatible. |
| Infineon 1ED34xxMX12H | Single-channel 6 A isolated driver with integrated Miller clamp; requires two units for dual-channel operation; different SOIC-16 footprint. | Lacks native dead time control and overlap protection-requires external logic or MCU coordination to prevent shoot-through. | Choose only if discrete channel control or Miller clamping is prioritized over integrated safety features and board space efficiency. |
Compared with Si8239AD-IS1R, SI82E39AGC-IS1R offers lower input deglitch delay for faster response in dynamic control loops; compared with 1ED34xxMX12H, it delivers true dual-channel integration with hardware-enforced dead time-reducing component count, layout complexity, and system-level validation effort.

FAQ
What is the isolation rating and safety certification status of SI82E39AGC-IS1R?
SI82E39AGC-IS1R provides 6 kVRMS isolation for one minute and is certified to UL 1577, VDE 60747-17 (reinforced insulation), CSA 62368-1, and CQC GB4943.1. It achieves 1500 VRMS working voltage and 10 kV bipolar surge capability-meeting requirements for reinforced insulation in automotive and industrial power systems.
Does SI82E39AGC-IS1R support both high-side and low-side gate driving in a half-bridge configuration?
Yes, SI82E39AGC-IS1R supports high-side/low-side operation via its universal input architecture (VIA/VIB) and independent VDDA/GNDA and VDDB/GNDB supplies. When configured with dead time enabled, it inserts hardware-controlled delay between VOA and VOB transitions to prevent shoot-through-making it ideal for half-bridge SiC/GaN inverters.
How is dead time programmed on SI82E39AGC-IS1R, and what is the range?
Dead time on SI82E39AGC-IS1R is set by an external resistor (RDT) connected between the DT pin and GNDI. With RDT = 10–110 kΩ, typical dead time ranges from ~17 ns to ~200 ns. Connecting DT to VDDI disables dead time insertion and overlap protection, allowing pure dual-driver operation.
What UVLO thresholds are available on SI82E39AGC-IS1R, and how are they selected?
SI82E39AGC-IS1R offers factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, VDDA, and VDDB. Threshold selection is fixed per orderable part number-no external components or configuration pins are required. The specific threshold is defined in the device's ordering guide and marked on the top-side label.
Is SI82E39AGC-IS1R pin-compatible with other Si82Ex family members like SI82E29 or SI82E89?
No-SI82E39AGC-IS1R uses the universal input configuration (VIA/VIB/EN), while SI82E29 uses VIA/VIB/DIS and SI82E89/SI82E99 use PWM/EN or PWM/DIS. Though all share the same SOIC-16 NB package and pin locations, input logic behavior and truth tables differ; direct substitution requires verification of control signal compatibility and firmware alignment.
