Product details
Overview
SI82F39BGC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with Universal configuration, CMOS input interface, and Selectable Variable Current Drive (SelVCD™) for driving SiC/GaN MOSFETs and IGBTs in half-bridge topologies. It delivers 6 kVRMS isolation, <5 ns channel-to-channel skew, 200 kV/µs CMTI, and programmable dead time via external resistor on DT pin. Used in onboard chargers and motor drives requiring high noise immunity and precise timing control.
For engineers reviewing the SI82F39BGC-IS1R datasheet, SI82F39BGC-IS1R pinout, SI82F39BGC-IS1R application, or SI82F39BGC-IS1R equivalent, this page provides verified functional identity, validated pin roles, confirmed SelVCD™ current levels, UVLO thresholds, isolation ratings, and real-world design implications - all extracted from Skyworks' official preliminary datasheet (206821A, May 2024).
Technical Context
The SI82F39BGC-IS1R implements dual capacitive isolation using silicon dioxide barriers, enabling differential RF-modulated signal transmission with OOK encoding for fault-tolerant timing. Its Universal configuration supports independent non-inverting inputs (VIA, VIB) and enables dual-driver operation when DT is tied to VDDI.
It integrates analog SPD± programming for eight-level sourcing/sinking current selection, Miller clamp activation below VMCTA/B (~1.9 V), and UVLO monitoring per supply rail (VDDI, VDDA, VDDB). The EN pin provides active-high enable control with tEID/tDID timing compliance, and outputs remain low during any supply UVLO condition.
Key Specifications

| Isolation Voltage | 6 kVRMS for 1 minute - meets reinforced insulation requirements per UL 1577, VDE 60747-17, and CSA 62368-1. |
| Channel Skew | <5 ns - ensures precise synchronous switching in half-bridge and phase-shifted topologies without shoot-through risk. |
| CMTI | >200 kV/µs - maintains signal integrity in high-dV/dt environments like SiC/GaN inverters and fast-switching PSUs. |
| Input Supply Range | 3 V to 20 V - compatible with 3.3 V, 5 V, and 15 V logic controllers without level-shifting. |
| Gate Supply Range | 5 V to 30 V - supports 12 V and 15 V gate drive for IGBTs and 10–20 V for SiC/GaN FETs. |
| UVLO Thresholds | Configurable at 4 V, 8 V, 12 V, or 15 V - prevents erratic turn-on during brownout or startup transients. |
| Operating Temp | –40 °C to +125 °C - qualified per AEC-Q100 for automotive powertrain and industrial motor control. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with 1.27 mm pitch and creepage ≥8.3 mm. RoHS-compliant, halogen-free, and rated for 1500 VRMS working voltage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for Channel A | Drives VOA high when asserted; Schmitt-triggered CMOS input with deglitch option. |
| VIB | Non-inverting logic input for Channel B | Drives VOB high when asserted; independent of VIA for dual-driver mode. |
| EN | Active-high enable control | Pulls both VOA and VOB low when deasserted; resumes operation within tEID after assertion. |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~10–110 ns); tie to VDDI to disable dead time and overlap protection. |

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 |
|---|---|---|---|
| Si8239BD-IS1R | Same Si82Fx family, but with Disable (DIS) input instead of Enable (EN); identical pinout, isolation, and SelVCD™ capability. | Preferred where system-level fault management uses active-high disable signaling rather than enable sequencing. | Select SI82F39BGC-IS1R for EN-based power-up coordination; choose Si8239BD-IS1R when DIS aligns with existing controller fault architecture. |
| UCC5390SCDWR | Texas Instruments part with 5.7 kVRMS isolation, 100 kV/µs CMTI, and fixed 4-A peak output - lacks SelVCD™, SPD±, and programmable dead time. | Suitable for cost-sensitive, lower-performance industrial drives where gate current tuning and Miller clamping are handled externally. | Choose SI82F39BGC-IS1R when adaptive gate drive, integrated Miller clamp, and sub-5 ns skew are required; UCC5390SCDWR fits simpler, fixed-drive designs. |
Compared with Si8239BD-IS1R, SI82F39BGC-IS1R offers identical isolation and timing performance but differs in control logic polarity (EN vs. DIS), making it optimal for enable-synchronized power sequencing. Against UCC5390SCDWR, SI82F39BGC-IS1R provides superior noise immunity, flexible current drive, and integrated protection - at the cost of higher design complexity for SPD± configuration.

FAQ
What is the isolation rating and safety certification status of SI82F39BGC-IS1R?
SI82F39BGC-IS1R provides 6 kVRMS isolation for 1 minute and is pending UL 1577 recognition, CSA 62368-1 (reinforced insulation), VDE 60747-17, and CQC GB4943.1 certifications. Its 1500 VRMS working voltage and 10 kV bipolar surge rating meet reinforced insulation requirements for industrial and automotive power systems. All isolation specifications are validated per Skyworks' preliminary datasheet 206821A.
Does SI82F39BGC-IS1R support both high-side/low-side and dual independent driver configurations?
Yes, SI82F39BGC-IS1R uses a Universal pinout that supports both modes. When the DT pin is connected to GND via a resistor, it operates as a high-side/low-side driver with programmable dead time. When DT is tied to VDDI, dead time and overlap protection are disabled, allowing independent control of VOA via VIA and VOB via VIB - effectively functioning as two isolated single-channel drivers. This flexibility is confirmed in Figures 2 and 14 of the datasheet.
How does the SelVCD™ technology in SI82F39BGC-IS1R eliminate the need for external gate resistors?
SI82F39BGC-IS1R's SelVCD™ implements an internal regulated current source for both sourcing (SPD+) and sinking (SPD−), offering eight selectable levels per channel. Because output current is actively controlled and maintained within ±10% over temperature and process variation, external gate resistors - traditionally used to limit di/dt - become redundant. This also enables the integrated Miller clamp to function directly at VOA/VOB pins without voltage drop interference.
What is the role of the EN pin in SI82F39BGC-IS1R, and how does it interact with UVLO conditions?
The EN pin is an active-high enable input: when logic high, SI82F39BGC-IS1R operates normally; when logic low, it forces both VOA and VOB low unconditionally. However, if VDDI is below its UVLO threshold (e.g., <4 V or <8 V depending on variant), the EN pin is ignored and outputs remain low regardless of EN state. This dual-layer protection ensures safe default behavior during brownout or incomplete power-up sequences.
Can SI82F39BGC-IS1R drive both SiC and GaN FETs, and what design considerations apply?
Yes, SI82F39BGC-IS1R is explicitly qualified for SiC MOSFETs, GaN FETs, IGBTs, and silicon MOSFETs. Its 5–30 V gate supply range supports 10–20 V SiC/GaN turn-on voltages, while SelVCD™ allows precise tuning of turn-on/turn-off currents to manage dV/dt and minimize switching losses. Critical design considerations include avoiding gate resistors (to preserve Miller clamp effectiveness) and ensuring SPD± traces are short and well-decoupled to maintain current-setting accuracy.
