Product details
Overview
SI82E39AGC-IS1 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 FETs in half-bridge topologies. Used in automotive-grade onboard chargers and industrial motor drives requiring robust noise immunity and precise dead-time control.
For engineers reviewing the SI82E39AGC-IS1 datasheet, SI82E39AGC-IS1 pinout, SI82E39AGC-IS1 application, or SI82E39AGC-IS1 equivalent, key selection criteria include its 3–20 V CMOS input range, programmable dead time via DT pin, UVLO thresholds (4/8/12/15 V options), voltage-mode drive architecture, and AEC-Q100 qualification for automotive power systems.
Technical Context
The SI82E39AGC-IS1 implements capacitive silicon-dioxide (SiO₂) isolation with differential RF-modulated OOK signaling, enabling high fault tolerance and timing consistency across temperature and lifetime. Its universal input architecture accepts independent non-inverting logic signals on VIA and VIB, with EN enabling synchronous operation of both channels.
Dead time is programmable via an external resistor on the DT pin (10–110 kΩ), generating typical delays from 22 ns to 250 ns; connecting DT to VDDI disables dead time and overlap protection, converting it to a dual independent driver. Output stage uses voltage-mode drive with external gate resistors to tune switching speed, overshoot, and EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577), reinforced insulation per VDE 60747-17, CSA 62368-1, and CQC GB4943.1. |
| Channel-to-Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate drive edges in half-bridge circuits. |
| CMTI | >200 kV/µs - prevents false triggering under fast transient common-mode noise in high-dv/dt power stages. |
| Peak Output Current | 6 A sourcing/sinking - supports fast turn-on/turn-off of high-capacitance SiC and GaN FETs without external buffers. |
| Input Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller logic, including microcontrollers and DSPs. |
| Gate Supply Range | 5–30 V - enables flexible biasing for diverse FET threshold voltages and Miller plateau requirements. |
| UVLO Thresholds | Factory-set at 4 V, 8 V, 12 V, or 15 V - prevents erratic switching during brown-out or startup/shutdown transitions. |
| Operating Temperature | –40 to +125 °C - qualified for under-hood automotive and industrial ambient environments. |
Pinout & Package
Narrow-body 16-pin SOIC package (GC suffix), with creepage/clearance optimized for reinforced isolation. Pinout matches Si82E39x Universal/Enable variant per Figure 2 of datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for Channel A | Drives VOA high when asserted; independent of VIB - enables asymmetric PWM or phase-shifted control. |
| VIB | Non-inverting logic input for Channel B | Drives VOB high when asserted; decoupled from VIA - supports dual independent gate drive paths. |
| EN | Active-high enable control | Pulls both VOA and VOB low when deasserted - provides fail-safe shutdown without relying on controller logic state. |
| DT | Dead time programming input | Sets delay between VOA/VOB transitions via external resistor; tied to VDDI to disable dead time and overlap protection. |
| VDDA / GNDA | Channel A gate driver supply and ground | Isolated 5–30 V power domain for high-side or low-side FET gate drive; supports bootstrap or isolated supply. |
| VDDB / GNDB | Channel B gate driver supply and ground | Independent isolated 5–30 V domain - enables split-rail or floating configurations for asymmetrical topologies. |
| VDDI / GNDI | Logic input supply and ground | 3–20 V digital interface side - galvanically separated from power domains by SiO₂ capacitors. |
| VOA / VOB | Gate driver outputs | Voltage-source outputs with 6 A peak drive - configured as unipolar (0–VDDA/B) or bipolar (±VDDA/B) via external circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Mode Drive | Uses external gate resistors (Rg) to directly control dV/dt, switching loss, and EMI - eliminates need for complex current-source compensation. |
| Programmable Dead Time | Resistor-tuned delay (22–250 ns) prevents shoot-through in half-bridge inverters without fixed internal timing constraints. |
| Overlap Protection | Hardware-level detection forces both outputs low if VIA and VIB go high simultaneously - failsafe against controller logic errors. |
| Shutdown Clamp | Active pull-down to GNDA/GNDB when VDDA/VDDB is unpowered - prevents parasitic turn-on of FETs during power sequencing. |
| AEC-Q100 Grade | Qualified to Grade 1 (–40 to +125 °C) with automotive-specific manufacturing flow - meets zero-defect requirements for EV traction inverters. |
| CMOS Input with Deglitch | Configurable deglitch filter rejects sub-50 ns noise spikes while adding minimal propagation delay - improves reliability in noisy motor drive 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 |
|---|---|---|---|
| Si82E30AD-IS1 | Same Si82E39x family but with disable (DIS) instead of enable (EN); identical pinout, specs, and isolation rating. | Preferred where controller asserts active-high disable signal rather than enable; truth table behavior differs only in EN/DIS polarity. | Select SI82E39AGC-IS1 when system-level fault handling requires positive-logic activation of gate drive functionality. |
| UCC5390SCD | TI part with 4 A peak drive, 100 kV/µs CMTI, and fixed 100 ns dead time; no deglitch option; different SOIC-16 pinout. | Lacks programmable dead time and overlap protection; not AEC-Q100 qualified; lower drive strength limits SiC/GaN use cases. | Choose SI82E39AGC-IS1 over UCC5390SCD when designing for automotive OBC or high-reliability industrial inverters requiring field-programmable timing and automotive qualification. |
Compared with Si82E30AD-IS1, SI82E39AGC-IS1 offers identical performance but inverted control logic polarity - critical for safety-critical EN-triggered shutdown. Against UCC5390SCD, SI82E39AGC-IS1 provides higher drive strength, superior noise immunity, and design flexibility via resistor-programmed dead time and overlap protection.

FAQ
What is the isolation voltage rating of the SI82E39AGC-IS1?
The SI82E39AGC-IS1 is safety-certified for 6 kVRMS isolation for one minute per UL 1577, with reinforced insulation compliance to VDE 60747-17, CSA 62368-1, and CQC GB4943.1. Its working voltage is rated at 1500 VRMS, and it withstands 10 kV bipolar surge - making it suitable for high-voltage automotive and industrial power systems where galvanic separation is critical.
Does the SI82E39AGC-IS1 support both high-side/low-side and dual independent configurations?
Yes, the SI82E39AGC-IS1 is a Universal-configuration device with independent VIA and VIB inputs. When the DT pin is connected to VDDI, dead time and overlap protection are disabled, allowing it to operate as two fully independent gate drivers. When DT is grounded via a resistor, it functions as a high-side/low-side driver with programmable dead time - providing topology flexibility without changing hardware.
What UVLO thresholds are implemented in the SI82E39AGC-IS1?
The SI82E39AGC-IS1 features factory-configured undervoltage lockout thresholds on VDDI, VDDA, and VDDB - selectable from 4 V, 8 V, 12 V, or 15 V per supply rail. These thresholds prevent erroneous switching during brown-out conditions and ensure clean startup/shutdown sequencing. The specific UVLO levels for this part are defined in its ordering code and verified in the Skyworks datasheet revision 206857C.
How does the SI82E39AGC-IS1 handle power sequencing between VDDI and VDDA/VDDB?
The SI82E39AGC-IS1 incorporates independent UVLO monitors and shutdown clamps for each supply domain. If VDDI drops below its UVLO threshold, both VOA and VOB are forced low regardless of input states. If VDDA or VDDB falls below its respective UVLO, the corresponding output enters a weak low state via the shutdown clamp - preventing parasitic turn-on of the driven FET even when the gate supply is unpowered.
Is the SI82E39AGC-IS1 qualified for automotive applications?
Yes, the SI82E39AGC-IS1 is AEC-Q100 qualified (Grade 1: –40 °C to +125 °C) and manufactured using automotive-specific process flows at all stages - including wafer fabrication, assembly, and test. It carries automotive-grade OPN designation (IS1 suffix) and meets zero-defect requirements for safety-critical EV subsystems such as onboard chargers and DC-DC converters.
