Product details
Overview
SI82E39BCC-IS1 from Skyworks Solutions is a dual-channel isolated gate driver with 6 A peak output current, designed for high-side/low-side half-bridge control in power converters and motor drives. It features 6 kVRMS reinforced isolation, <5 ns channel-to-channel skew, CMOS inputs, and programmable dead time via external resistor. It drives SiC, GaN, IGBT, and MOSFET power switches in automotive-grade applications.
For engineers reviewing the SI82E39BCC-IS1 datasheet, SI82E39BCC-IS1 pinout, SI82E39BCC-IS1 application, or SI82E39BCC-IS1 equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, automotive-qualified isolation performance, and two confirmed alternative parts for half-bridge gate drive systems requiring high CMTI (>200 kV/μs) and robust UVLO.
Technical Context
The SI82E39BCC-IS1 implements capacitive silicon-dioxide (SiO₂) isolation with differential RF-modulated OOK signaling, enabling 6 kVRMS one-minute isolation and >200 kV/μs common-mode transient immunity. Its dual-channel architecture supports High-Side/Low-Side configuration with independent VDDA/GNDA and VDDB/GNDB supplies, each with dedicated UVLO thresholds (4 V, 8 V, 12 V, or 15 V).
It uses voltage-mode drive with external gate resistors to control slew rate and overshoot, and integrates active shutdown clamps on both outputs to prevent parasitic turn-on during unpowered states. The DT pin enables resistor-programmable dead time (10–110 kΩ range), and EN input provides synchronous enable/disable control with defined low-state outputs during disable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for one minute - meets UL 1577, VDE 60747-17, and CSA 62368-1 reinforced insulation requirements. |
| CMTI | >200 kV/μs - ensures reliable operation in high dv/dt environments like SiC/GaN inverters without false triggering. |
| Channel Skew | <5 ns - guarantees precise timing alignment between high-side and low-side outputs to prevent shoot-through. |
| Peak Output Current | 6 A sourcing/sinking - directly drives large gate capacitances of 1200 V SiC FETs or 650 V GaN HEMTs 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 - supports 12 V and 15 V gate bias for IGBTs and 10 V for SiC/GaN, with independent UVLO per channel. |
| Operating Temp | –40 to +125 °C - qualified to AEC-Q100 Grade 1, suitable for under-hood automotive and industrial motor drives. |
Pinout & Package
Narrow-body 16-pin SOIC package (BCC suffix), with creepage/clearance optimized for reinforced insulation. Pinout matches Si82E39x Universal/High-Side-Low-Side variant with EN input.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for Channel A | Drives VOA high when asserted; used in universal mode for independent high-side control. |
| VIB | Non-inverting logic input for Channel B | Drives VOB high when asserted; used in universal mode for independent low-side control. |
| EN | Active-high enable input | Pulls both VOA and VOB low when deasserted (logic low); enables fast system-level fault shutdown. |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → ~10–120 ns); tied to VDDI disables dead time for dual-driver use. |
| VDDA / GNDA | Channel A gate driver supply and ground | Independent 5–30 V supply with dedicated UVLO; isolates high-side gate bias from low-side noise. |
| VDDB / GNDB | Channel B gate driver supply and ground | Independent 5–30 V supply with dedicated UVLO; enables asymmetric gate bias (e.g., 15 V high-side / 12 V low-side). |
| VOA / VOB | High-side and low-side gate drive outputs | Voltage-mode outputs with short-circuit clamp and shutdown clamp; no undefined states during power sequencing. |
| VDDI / GNDI | Logic input supply and ground | 3–20 V CMOS-compatible supply with deglitch filter option; powers isolation barrier and input logic. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Mode Drive | Enables precise control of gate rise/fall times using standard external gate resistors-no special current-source design needed. |
| Programmable Dead Time | Resistor-tuned delay (10–110 kΩ) inserts user-defined non-overlap between VOA/VOB transitions, preventing shoot-through in half-bridges. |
| Automotive-Grade Qualification | AEC-Q100 Grade 1 qualified with manufacturing flow traceability-meets zero-defect requirements for EV traction inverters and OBCs. |
| Robust UVLO Architecture | Independent UVLO on VDDI, VDDA, and VDDB with selectable thresholds (4/8/12/15 V)-ensures safe startup/shutdown across all power rails. |
| Shutdown Clamp | Active pull-down to GNDA/GNDB when VDDA/VDDB is unpowered-eliminates risk of parasitic FET turn-on during power loss or sequencing. |
Applications
| EV Onboard Charger (OBC) | Industrial Motor Drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated gate drive applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8239BD-IS1 | Same Si82E39 family, but with DIS (disable) instead of EN (enable) input logic polarity. | Requires inverted control signal from MCU; identical isolation, skew, and drive strength. | Select when system-level fault signaling uses active-high disable rather than active-high enable. |
| UCC5390SCD | TI part with 5.7 A peak drive, 5 kVRMS isolation, and integrated Miller clamp-but no programmable dead time or AEC-Q100 grade. | Lacks resistor-tunable dead time and automotive qualification; lower CMTI (150 kV/μs). | Consider only for non-automotive, cost-sensitive designs where dead time is fixed externally or not required. |
Compared with SI82E39BCC-IS1, Si8239BD-IS1 offers identical performance with inverted enable logic-ideal for legacy control firmware reuse-while UCC5390SCD trades off programmable dead time and automotive qualification for lower cost and integrated Miller clamping in non-safety-critical applications.

FAQ
What is the isolation rating of the SI82E39BCC-IS1 and which safety standards does it meet?
The SI82E39BCC-IS1 provides 6 kVRMS reinforced isolation rated for one minute, certified to UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1. This enables direct interface with mains-referenced power stages in OBCs, UPS, and solar inverters without additional isolation barriers. SI82E39BCC-IS1 meets 2 MOPP requirements per IEC 60601-1 for medical-grade power supplies.
Does the SI82E39BCC-IS1 support both high-side/low-side and dual independent configurations?
Yes, the SI82E39BCC-IS1 supports High-Side/Low-Side operation by default, with dead time programmable via the DT pin. Connecting DT to VDDI disables dead time and overlap protection, reconfiguring SI82E39BCC-IS1 as a dual independent gate driver for applications like three-phase inverter topologies requiring separate control of each switch.
What UVLO thresholds are available on the SI82E39BCC-IS1 and how are they selected?
The SI82E39BCC-IS1 offers factory-configurable UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, VDDA, and VDDB-each independently set per supply rail. Threshold selection is determined at wafer sort and encoded in the part number; SI82E39BCC-IS1 uses 12 V UVLO on VDDA and VDDB, and 8 V on VDDI, ensuring robust startup for 15 V gate supplies and 5 V logic interfaces.
How does the EN pin function on the SI82E39BCC-IS1 during fault conditions?
The EN pin on SI82E39BCC-IS1 is an active-high enable that forces both VOA and VOB to logic low within tDID (≤120 ns) when deasserted. This provides deterministic, sub-200 ns fault shutdown-critical for protecting SiC/GaN switches during overcurrent events. SI82E39BCC-IS1 maintains this behavior even if VDDA or VDDB is unpowered, thanks to its internal shutdown clamp.
Is the SI82E39BCC-IS1 pin-compatible with other Si82Ex variants such as Si82E29 or Si82E89?
No, SI82E39BCC-IS1 is not pin-compatible with Si82E29 (disable-input variant) or Si82E89 (PWM-input variant). While all share the same narrow-body SOIC-16 package footprint, pin functions differ: SI82E39BCC-IS1 uses VIA/VIB/EN/DT, whereas Si82E29 uses VIA/VIB/DIS/DT and Si82E89 uses PWM/DIS/DT. PCB layout must match the specific Si82E39x pinout shown in Figure 2 of the datasheet.
