Product details
Overview
SI82F39BCC-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. Used in onboard chargers and motor drives requiring robust noise immunity and Miller clamping.
For engineers reviewing the SI82F39BCC-IS1R datasheet, SI82F39BCC-IS1R pinout, SI82F39BCC-IS1R application, or SI82F39BCC-IS1R equivalent, key selection criteria include its Universal pinout (VIA/VIB inputs), EN-enable logic, SPD±-programmable sourcing/sinking current (8 levels), integrated Miller clamp, and AEC-Q100 qualification for automotive power systems.
Technical Context
The SI82F39BCC-IS1R implements capacitive digital isolation using dual SO₂ dielectric barriers, enabling 6 kVRMS reinforced insulation and >200 kV/μs common-mode transient immunity. Its Universal configuration accepts independent non-inverting inputs (VIA, VIB) and uses an active-high EN signal to enable both outputs.
Dead time is resistor-programmable via DT pin (10–110 kΩ), while SPD+ and SPD− pins set matched sourcing/sinking current across both channels using either static resistor dividers or dynamic voltage control. Output stage operates as a precision current source with ±10% tolerance over temperature and process for UVLO ≥8 V variants.
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 Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate drive signals in half-bridge circuits. |
| CMTI | >200 kV/μs - prevents false triggering in noisy high-dv/dt environments like SiC/GaN inverters. |
| Input Supply Range | 3 V to 20 V - supports direct connection to MCU I/O or level-shifted control logic without external regulators. |
| Gate Drive Supply | 5 V to 30 V - accommodates wide range of power switch gate thresholds including 12 V SiC FETs and 15 V IGBTs. |
| UVLO Threshold | 12 V (typical) - provides stable turn-on margin for gate drivers operating from 15 V supplies with ripple tolerance. |
| Operating Temp | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
Pinout & Package
Narrow-body 16-pin SOIC package (7.5 mm width) with creepage-optimized layout for reinforced isolation. Pin 1 marked by dot; pins 12 and 13 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting input for channel A | Accepts CMOS-level PWM or logic signal; enables independent control of high-side or low-side output. |
| VIB | Non-inverting input for channel B | Paired with VIA for true dual-driver operation; no cross-coupling or fixed phase relationship required. |
| EN | Active-high enable | Drives both VOA and VOB low when deasserted; overrides all input states for safe shutdown. |
| DT | Dead time programming | Resistor-to-GND sets delay (10–110 kΩ → ~10–190 ns); connect to VDDI to disable dead time for dual-driver mode. |
| SPD+ | Sourcing current control | Selects one of eight turn-on current levels (0.5–10 A typical); eliminates need for external gate resistors. |
| SPD− | Sinking current control | Selects matching turn-off current level; enables fast Miller clamping during switching transitions. |
| VOA / VOB | Isolated gate drive outputs | Current-source outputs with integrated Miller clamp; directly drive power device gates without series resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | 8-step programmable sourcing/sinking current (0.5–10 A) with ±10% regulation across temp/process - replaces gate resistors and enables adaptive switching speed. |
| Integrated Miller Clamp | Automatically engages during VOH→VOL transition at VMCTA/B threshold - suppresses Miller-induced shoot-through without external components. |
| Programmable Dead Time | Resistor-adjustable (10–110 kΩ) dead time up to ~190 ns with overlap protection - prevents cross-conduction in half-bridge configurations. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C) with automotive-specific manufacturing flow - certified for safety-critical traction inverters and OBCs. |
| High-Voltage Input Tolerance | CMOS inputs with deglitch filter option - withstands >4 kV HBM ESD and rejects fast transients 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 |
|---|---|---|---|
| Si8239BD-IS1R | Same Si82Fx family, but with Disable (DIS) input instead of Enable (EN); identical pinout and SelVCD™/Miller clamp features. | Preferred where system-level fault handling requires active-high disable rather than enable logic. | Select SI82F39BCC-IS1R for EN-based safety architectures; choose Si8239BD-IS1R only if DIS logic matches existing control firmware. |
| UCC5390SCDR | Texas Instruments part with 5.7 kVRMS isolation, 100 kV/μs CMTI, and fixed 4 A/6 A sourcing/sinking - no SelVCD™ or SPD± programming. | Lacks programmable current drive and Miller clamp; requires external gate resistors and clamping diodes. | Use UCC5390SCDR only in cost-sensitive designs where fixed drive strength suffices and layout area allows external components. |
Compared with Si8239BD-IS1R, SI82F39BCC-IS1R offers identical isolation and timing performance but differs in control logic polarity; versus UCC5390SCDR, it delivers superior design flexibility through resistor-programmable drive strength and integrated Miller clamping - reducing BOM count and PCB area in high-reliability power systems.

FAQ
What is the isolation rating and safety certification status of SI82F39BCC-IS1R?
SI82F39BCC-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. It supports 1500 VRMS working voltage and 10 kV bipolar surge immunity, meeting requirements for reinforced insulation in automotive and industrial power systems.
Does SI82F39BCC-IS1R support both high-side/low-side and dual independent configurations?
Yes, SI82F39BCC-IS1R uses the Universal pinout (VIA/VIB inputs) and supports both modes. Connecting DT to GND enables dead time insertion for high-side/low-side half-bridge operation; connecting DT to VDDI disables dead time and overlap protection, allowing independent dual-channel control of two separate switches.
How does the SelVCD™ technology in SI82F39BCC-IS1R eliminate the need for external gate resistors?
SI82F39BCC-IS1R's SelVCD™ implements a precision current-source output stage where SPD+ and SPD− pins select one of eight sourcing/sinking current levels (0.5–10 A). Because output current is actively regulated, external gate resistors are unnecessary - and adding them would degrade Miller clamp effectiveness and increase switching losses.
What is the function of the Miller clamp in SI82F39BCC-IS1R and when does it activate?
The Miller clamp in SI82F39BCC-IS1R activates automatically when VOA or VOB falls below the VMCTA/B threshold during turn-off. It temporarily boosts sinking current to SPD7− level to rapidly discharge the power device gate and suppress Miller-induced turn-on. It remains engaged until the next rising edge, ensuring robust immunity to parasitic coupling.
Is SI82F39BCC-IS1R qualified for automotive applications?
Yes, SI82F39BCC-IS1R is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C) and built using automotive-specific manufacturing flows. It is designated for safety-critical applications including traction inverters, onboard chargers, and DC-DC converters in electric vehicles.
