Product details
Overview
SI82E39BBC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with 6 A peak output current, universal configuration (independent high-side/low-side control), and enable (EN) input. 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 onboard chargers and motor drives requiring precise timing and robust noise immunity.
For engineers reviewing the SI82E39BBC-IS1R datasheet, SI82E39BBC-IS1R pinout, SI82E39BBC-IS1R application, or SI82E39BBC-IS1R equivalent, key selection criteria include its 3–20 V logic supply 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-grade reliability.
Technical Context
The SI82E39BBC-IS1R implements capacitive silicon-dioxide isolation with differential RF-modulated OOK signaling, enabling high fault tolerance and tight timing matching. Its universal configuration supports independent VIA/VIB inputs with EN-controlled enable/disable behavior and DT-pin-programmable dead time insertion between VOA and VOB transitions.
It features integrated shutdown clamps, short-circuit protection clamping to VDDA/B, thermal shutdown at 150 °C, and CMOS-compatible Schmitt-triggered inputs with deglitch filtering. UVLO operates independently on VDDI, VDDA, and VDDB rails to ensure safe startup/shutdown sequencing.
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-to-Channel Skew | <5 ns - enables precise synchronous switching in high-frequency half-bridge inverters without shoot-through risk. |
| CMTI | >200 kV/µs - ensures reliable operation in noisy high-dV/dt environments like SiC/GaN-based power converters. |
| Peak Output Current | 6 A sourcing/sinking - drives high-gate-charge wide-bandgap FETs with fast turn-on/turn-off times. |
| Logic Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller interfaces without level-shifting. |
| Gate Supply Range | 5–30 V - supports bipolar (±15 V) or unipolar (12 V/15 V) gate bias for MOSFET/IGBT/SiC/GaN devices. |
| Operating Temperature | –40 to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage/clearance optimized for reinforced isolation. Pinout supports universal dual-input operation with active-high EN control and DT-based dead time programming.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for channel A | Directly controls VOA output state; high = VOA high (if enabled and powered). |
| VIB | Non-inverting logic input for channel B | Directly controls VOB output state; high = VOB high (if enabled and powered). |
| EN | Active-high enable input | Drives both VOA and VOB low when deasserted (logic low); enables normal operation when asserted (logic high). |
| DT | Dead time programming terminal | Resistor-to-GND sets dead time (10–110 kΩ → ~18–200 ns); tied to VDDI disables dead time and overlap protection. |
| VDDI | Logic input supply | 3–20 V rail powering internal digital logic and isolation modulator; includes 4/8/12/15 V UVLO options. |
| GNDI | Logic input ground | Reference for all digital inputs (VIA, VIB, EN, DT); galvanically isolated from GNDA/GNDB. |
| VDDA / GNDA | Channel A gate driver supply/ground | 5–30 V isolated supply for high-side or low-side driver A; includes independent UVLO monitoring. |
| VDDB / GNDB | Channel B gate driver supply/ground | 5–30 V isolated supply for second channel; UVLO and thermal shutdown operate independently. |
| VOA / VOB | Gate driver outputs | Voltage-mode outputs with 6 A peak drive; clamp to VDDA/B during overvoltage and to GNDA/B when unpowered. |
Key Features
| Feature | Design Value |
|---|---|
| Universal pinout with EN input | Supports independent high-side/low-side control (VIA/VIB) and enables system-level fault shutdown without external logic. |
| Voltage-mode drive architecture | Uses external gate resistors (Rg) to tune switching speed, EMI, and overshoot-no current-source complexity or thermal derating. |
| Programmable dead time & overlap protection | Prevents shoot-through by forcing both outputs low on simultaneous high inputs; DT resistor sets delay before opposite channel turns on. |
| Independent triple-rail UVLO | Monitors VDDI, VDDA, and VDDB separately-ensures safe operation even if one gate supply fails while others remain active. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient; manufactured in automotive-specific process flows with zero defect escape targets. |
Applications

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 |
|---|---|---|---|
| Si8239BB-IS1R | Same family, but disable (DIS) input instead of enable (EN); identical pinout, specs, and isolation rating. | Preferred where system-level fault response requires active-high disable assertion rather than enable activation. | Select SI82E39BBC-IS1R when controller logic naturally asserts an enable signal; choose Si8239BB-IS1R for DIS-driven safety architectures. |
| UCC5390SCD | TI device with 10 A peak drive, 35 V max VDD, and integrated Miller clamp-but only 5 kVRMS isolation and no AEC-Q100 grade. | Suitable for industrial non-automotive inverters needing higher peak current but lower isolation compliance burden. | Choose UCC5390SCD for cost-sensitive industrial designs without reinforced insulation mandates; retain SI82E39BBC-IS1R for automotive or safety-critical 6 kVRMS applications. |
Compared with Si8239BB-IS1R, SI82E39BBC-IS1R offers identical performance but inverted control polarity-critical for matching existing MCU GPIO logic states. Versus UCC5390SCD, it trades peak current for certified 6 kVRMS isolation and AEC-Q100 qualification, making it the only choice for ISO 26262 ASIL-B–capable systems.

FAQ
What is the isolation rating of the SI82E39BBC-IS1R and which safety standards does it meet?
The SI82E39BBC-IS1R provides 6 kVRMS isolation for one minute and is certified to UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1 for reinforced insulation. Its 1500 VRMS working voltage and 10 kV bipolar surge rating make it suitable for high-voltage industrial and automotive applications where creepage and clearance must exceed 8 mm.
How does the DT pin function in the SI82E39BBC-IS1R, and what happens when it is tied to VDDI?
In the SI82E39BBC-IS1R, the DT pin sets dead time between VOA and VOB transitions using an external resistor to GND (10–110 kΩ → ~18–200 ns). When DT is tied to VDDI, dead time insertion and overlap protection are disabled, allowing the device to operate as a true dual independent driver-ideal for totem-pole or resonant topologies requiring simultaneous switching.
Does the SI82E39BBC-IS1R support both unipolar and bipolar gate drive voltages?
Yes, the SI82E39BBC-IS1R supports unipolar (e.g., 0–15 V) and bipolar (e.g., –5/+15 V) gate drive configurations. Its voltage-mode output stage and independent VDDA/VDDB supplies allow asymmetric biasing-enabling negative turn-off voltage for enhanced SiC/GaN FET ruggedness and reduced Miller-induced false turn-on.
What UVLO thresholds are available for the SI82E39BBC-IS1R, and how are they selected?
The SI82E39BBC-IS1R offers factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, and matching thresholds on VDDA/VDDB. These are fixed per orderable part number-not user-adjustable-and selected at manufacturing based on the OPN suffix. The SI82E39BBC-IS1R uses 12 V UVLO on all rails, ensuring robust startup above typical 12 V automotive battery dips.
Is the SI82E39BBC-IS1R pin-compatible with other Si82Ex variants such as Si82E29 or Si82E89?
No-SI82E39BBC-IS1R is not pin-compatible with Si82E29x (disable input), Si82E89x (PWM input), or Si82E99x (PWM + disable). While all share the same SOIC-16 NB package footprint, pin functions differ: SI82E39BBC-IS1R uses VIA/VIB/EN/DT, whereas Si82E29x substitutes DIS for EN, and Si82E89x replaces VIA/VIB with PWM. PCB layout must match the exact variant.
