Product details
Overview
SI82F39BBE-IS3R from Skyworks Solutions is a dual-channel isolated gate driver in narrow-body 16-pin SOIC package, configured for universal (independent) operation with enable (EN) input, 3–20 V logic supply, 5–30 V gate supply, and integrated SelVCD™ current-source outputs delivering up to 8 A peak sourcing/sinking across eight programmable levels. It drives SiC/GaN FETs and IGBTs in half-bridge motor inverters.
For engineers reviewing the SI82F39BBE-IS3R datasheet, SI82F39BBE-IS3R pinout, SI82F39BBE-IS3R application, or SI82F39BBE-IS3R equivalent, key selection criteria include channel-to-channel skew (<5 ns), CMTI (>200 kV/µs), 6 kVRMS isolation, Miller clamp integration, and dead time programmability via external resistor on DT pin.
Technical Context
The SI82F39BBE-IS3R implements dual independent CMOS-isolated channels using silicon dioxide capacitive barriers, supporting differential RF-modulated signal transmission with OOK encoding for high noise immunity and precise timing. Its logic inputs (VIA, VIB, EN) are Schmitt-triggered, deglitch-capable, and tolerate 3–20 V supply.
It features two independently regulated gate drive outputs (VOA, VOB) operating as precision current sources with ±10% tolerance over temperature and process for UVLO ≥8 V variants. The SPD+ and SPD− pins configure sourcing/sinking current simultaneously for both channels using resistor-based voltage dividers or dynamic analog control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for 1 minute - meets reinforced insulation requirements per UL 1577, VDE 60747-17, and CSA 62368-1. |
| Channel-to-Channel Skew | <5 ns - ensures synchronous switching of high-side and low-side FETs in half-bridge topologies without shoot-through risk. |
| CMTI | >200 kV/µs - prevents false triggering in noisy high-dV/dt environments like SiC/GaN power stages. |
| Logic Supply Range | 3 V to 20 V - supports direct interface with microcontrollers, DSPs, and FPGA I/O without level-shifting. |
| Gate Drive Output | Current-source architecture with 8 selectable levels (up to 8 A peak) - eliminates external gate resistors and enables adaptive Miller clamping. |
| UVLO Threshold | Programmable at 4 V, 8 V, 12 V, or 15 V - ensures reliable turn-on only when gate supply is sufficient to fully enhance power devices. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 for automotive under-hood and industrial motor control applications. |
Pinout & Package
Narrow-body 16-pin SOIC (NB SOIC-16) package with creepage/clearance optimized for reinforced insulation. Pin 1 marked by dot; pins 12 and 13 are NC (no connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for channel A | Directly controls VOA output state; high = VOA high (if enabled), low = VOA low. |
| VIB | Non-inverting logic input for channel B | Directly controls VOB output state; high = VOB high (if enabled), low = VOB low. |
| EN | Active-high enable input | Drives both VOA and VOB low when logic low; enables normal operation when high. |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~10–110 ns); connect to VDDI to disable dead time for dual-driver mode. |
| SPD+ | Sourcing current programming input | Resistor-to-GND selects one of eight sourcing current levels (1–8 A peak) for both VOA and VOB. |
| SPD− | Sinking current programming input | Resistor-to-GND selects one of eight sinking current levels (1–8 A peak) for both VOA and VOB. |
| VDDI | Logic input supply | Provides power for digital isolation barrier and input circuitry; range 3–20 V. |
| GNDI | Logic input ground | Reference for all logic inputs (VIA, VIB, EN, DT, SPD±); galvanically isolated from power grounds. |
| VDDA / GNDA | Channel A gate driver supply / ground | Independent 5–30 V supply for VOA output stage; GNDA is isolated return path. |
| VDDB / GNDB | Channel B gate driver supply / ground | Independent 5–30 V supply for VOB output stage; GNDB is isolated return path. |
| VOA / VOB | Gate driver outputs | Current-source outputs with integrated Miller clamp; directly drive MOSFET/IGBT gates without external resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels (1–8 A peak) set via SPD+/SPD− resistors - replaces gate resistors and enables adaptive switching speed control. |
| Integrated Miller Clamp | Automatically engages during VOA/VOB falling edge when output voltage drops below VMCTA/B - suppresses Miller-induced turn-on in high-dV/dt conditions without external components. |
| Programmable Dead Time | Resistor-controlled DT pin sets inter-channel delay (10–110 ns typical) - prevents shoot-through in half-bridge configurations while allowing universal mode disable. |
| High CMTI & Low Skew | >200 kV/µs common-mode transient immunity and <5 ns channel-to-channel skew - maintains signal integrity in fast-switching SiC/GaN systems. |
| AEC-Q100 Qualified | Automotive-grade qualification across full –40 °C to +125 °C junction range - validated for onboard chargers, traction inverters, and EPS systems. |

FAQ
What is the isolation rating and safety certification status of SI82F39BBE-IS3R?
The SI82F39BBE-IS3R 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 applications. SI82F39BBE-IS3R achieves this via dual silicon dioxide capacitors in its isolation barrier.
Does SI82F39BBE-IS3R support both high-side/low-side and independent dual-channel configurations?
Yes, SI82F39BBE-IS3R is configured as a universal (independent) dual-channel driver with VIA and VIB inputs, enabling asynchronous control of VOA and VOB. It supports high-side/low-side operation only when used with dead time programming via the DT pin; connecting DT to VDDI disables dead time and reverts to pure dual-driver mode. This flexibility is defined by its bond-out and confirmed in the Si82F39x pinout diagrams.
How does the SelVCD™ technology in SI82F39BBE-IS3R eliminate the need for external gate resistors?
SI82F39BBE-IS3R implements SelVCD™ as a precision current-source output stage, where SPD+ and SPD− pins select one of eight fixed sourcing/sinking current levels (1–8 A peak). Because output current is actively regulated-not voltage-limited-the driver delivers consistent gate charge/discharge rates regardless of gate voltage swing or FET capacitance, removing reliance on passive resistors for speed control or Miller suppression.
What is the function of the Miller clamp in SI82F39BBE-IS3R and how is it activated?
The Miller clamp in SI82F39BBE-IS3R engages automatically during the falling edge of VOA or VOB when the output voltage drops below the threshold VMCTA/B (~2 V). It temporarily switches sinking current to the highest SPD7− level to rapidly discharge the Miller capacitance and prevent spurious turn-on. The clamp remains active until the next rising edge and requires no external components-its operation is intrinsic to the SI82F39BBE-IS3R's output stage design.
Can SI82F39BBE-IS3R be used in automotive applications, and what qualifications does it hold?
Yes, SI82F39BBE-IS3R is AEC-Q100 qualified for Grade 1 (–40 °C to +125 °C) operation and built using automotive-specific manufacturing flows. It supports automotive applications including onboard chargers, traction inverters, and electric power steering systems. Its 6 kVRMS isolation, >200 kV/µs CMTI, and integrated protections (UVLO, Miller clamp, dead time) meet functional safety requirements for ASIL-B capable systems when implemented per manufacturer guidelines.
