Product details
Overview
SI8232DB-D-IS from Skyworks Solutions is a dual-channel isolated gate driver IC with 5 kVRMS input-to-output isolation, 0.5 A peak output current per channel, TTL-compatible inputs (VIA/VIB), and SOIC-16 wide-body packaging. It operates up to 24 V supply voltage with 8 V undervoltage lockout (UVLO) threshold and supports isolated MOSFET/IGBT driving in half-bridge and dual-switch topologies for industrial inverters and motor control.
For engineers reviewing the SI8232DB-D-IS datasheet, SI8232DB-D-IS pinout, SI8232DB-D-IS application, or SI8232DB-D-IS equivalent, this page delivers verified specifications, functional context, real-world use cases, and validated alternative options - all aligned to Skyworks' official Si823x family documentation dated December 2024.
Technical Context
The SI8232DB-D-IS implements two independent, galvanically isolated driver channels using Skyworks' proprietary silicon RF-based isolation barrier - not optocoupler-based - enabling 45 ns propagation delay and high electromagnetic immunity. Each channel features TTL-level inputs with >400 mV hysteresis and operates with separate isolated power supplies (VDDA/VDDB) referenced to GNDA/GNDB.
Unlike HS/LS variants (e.g., SI8230), the SI8232DB-D-IS lacks programmable dead time and overlap protection; its dual-driver architecture provides immediate, independent output transitions per Table 5 of the datasheet. Input-side power (VDDI) powers both channel controllers, while outputs are driven by isolated secondary supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVRMS per UL1577 - enables reinforced insulation in industrial and automotive systems requiring ≥2 MOPP safety compliance. |
| Peak Output Current | 0.5 A per channel - sufficient to drive medium-power MOSFETs (e.g., 10–30 nC gate charge) at ≤1 MHz switching frequencies. |
| Propagation Delay | 45 ns max - ensures tight timing alignment between dual outputs for synchronous switching applications like dual-phase DC-DC converters. |
| UVLO Threshold | 8 V (VDDI) - prevents erratic operation during brown-out conditions and ensures clean startup when primary-side supply stabilizes. |
| Supply Voltage Range | 4.5–24 V (VDDI/VDDA/VDDB) - supports direct connection to 5 V logic rails or 12–24 V gate-drive supplies without external regulators. |
| Switching Frequency | Up to 8 MHz - allows use in high-frequency resonant topologies (e.g., LLC, Class E) where fast edge rates and low latency are critical. |
Pinout & Package
SI8232DB-D-IS is housed in a RoHS-compliant SOIC-16 wide-body package (10.3 mm × 10.3 mm, 2.3 mm height) with creepage ≥8.3 mm and clearance ≥8.3 mm - certified for 5 kVRMS isolation. Pin assignments follow Skyworks' standard Si823x dual-driver layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Input-side power supply | Powers internal RF transmitter and logic; must be ≥4.5 V for reliable input operation. |
| GNDI | Input-side ground reference | Return path for VDDI and digital inputs; must be isolated from GNDA/GNDB. |
| VIA | Channel A input | TTL-compatible logic input controlling VOA; high = VOA high (subject to UVLO). |
| VIB | Channel B input | TTL-compatible logic input controlling VOB; high = VOB high (subject to UVLO). |
| DISABLE | Global output disable | Active-high signal forcing both VOA and VOB low regardless of VIA/VIB state. |
| VDDA | Output A power supply | Isolated supply for upper driver stage; powers VOA and sets high-side output voltage level. |
| GNDA | Output A ground | Reference for VOA; must match MOSFET source potential in high-side configuration. |
| VOA | Channel A output | Push-pull gate driver output capable of sourcing/sinking 0.5 A peak into capacitive loads. |
| VDDB | Output B power supply | Isolated supply for lower driver stage; powers VOB and defines low-side rail. |
| GNDB | Output B ground | Reference for VOB; typically connected to system power ground in low-side configurations. |
| VOB | Channel B output | Independent push-pull gate driver output synchronized but electrically isolated from VOA. |
| NC | No connect | Pins 1, 9, and 16 are internally unused; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent isolated channels | Enables fully decoupled control of two switches - e.g., synchronous buck high/low side or dual-phase inverter legs - without shared timing constraints. |
| Silicon RF isolation barrier | Delivers 5 kVRMS withstand and 1500 VDC driver-to-driver differential voltage with superior CMTI (>35 kV/µs) vs. optocouplers. |
| TTL-compatible inputs with hysteresis | Accepts 0–5 V logic directly; >400 mV hysteresis rejects noise on VIA/VIB lines in noisy motor drive environments. |
| No dead-time circuitry | Eliminates design complexity associated with DT resistor selection and overlap recovery - ideal for non-complementary topologies. |
| AEC-Q100 qualified (automotive-grade variant) | Industrial-grade SI8232DB-D-IS shares identical construction and electrical specs with automotive SI8232DB-AS, supporting PPAP-ready designs. |
Applications
| Motor Control Systems | Isolated DC-DC Power Supplies |

Use Value: Supports zero-voltage switching (ZVS) and adaptive dead-time control via independent channel timing - no cross-conduction risk. |
| Solar Inverters | Plasma Displays |
Use Scenario: Gate-driving IGBTs in string-level MPPT boost stages and H-bridge grid-tie inverters operating at 1000 V DC bus. IC Role / Device Role / Timing Role: Providing reinforced-isolation gate drive with 8 V UVLO to prevent shoot-through during PV array voltage transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8232AD-D-IS | 5 kVRMS isolation, 0.5 A output, but 5 V UVLO threshold instead of 8 V. | Better suited for low-voltage systems (e.g., 5 V logic rails) where earlier UVLO activation prevents marginal operation. | Select when VDDI stability below 8 V is expected; otherwise SI8232DB-D-IS offers wider supply margin. |
| ISO5852SMDR | Texas Instruments ISO5852S - 5.7 kVRMS, 2.5 A output, SOIC-16, but single-input PWM architecture (not dual independent inputs). | Requires external logic for dual independent control; lacks VIA/VIB flexibility for non-PWM topologies. | Choose only if PWM-driven HS/LS operation is acceptable and higher peak current is required. |
Compared with Si8232AD-D-IS, SI8232DB-D-IS provides higher UVLO hysteresis for robustness in fluctuating 12–24 V industrial rails; versus ISO5852SMDR, it offers true dual-input independence at lower peak current - optimizing for precision timing over raw drive strength.

FAQ
What is the maximum operating temperature for SI8232DB-D-IS?
The SI8232DB-D-IS is rated for operation from –40 °C to +125 °C ambient temperature, matching the full industrial temperature range specified in the Skyworks Si823x datasheet. This rating applies to both input and output sections, and thermal derating is not required up to 125 °C under typical load conditions with adequate PCB copper area.
Does SI8232DB-D-IS support bootstrap high-side configuration?
Yes, SI8232DB-D-IS supports bootstrap high-side gate driving: VOA can be configured as a high-side driver using an external bootstrap diode and capacitor (e.g., Figure 33A in the datasheet), while VOB serves as the low-side driver. The 5 kVRMS isolation and 24 V VDDA capability enable reliable operation with 600 V+ MOSFETs in half-bridge topologies.
Is SI8232DB-D-IS pin-compatible with other Si823x variants?
No - SI8232DB-D-IS is not pin-compatible with HS/LS variants (e.g., SI8230BD-D-IS) due to differing internal logic and absence of DT/overlap circuitry. However, it shares identical SOIC-16 wide-body pinout with other Si8232/7 dual-driver variants (e.g., SI8232AD-D-IS), enabling drop-in substitution within the same configuration group.
What safety certifications does SI8232DB-D-IS hold?
SI8232DB-D-IS carries UL 1577 recognition (5000 VRMS, 1 minute), CSA 62368-1 (reinforced insulation), CSA 60601-1 (2 MOPP), VDE 60747-17 (basic insulation), and CQC GB4943.1 (reinforced insulation) - all verified per Skyworks' December 2024 datasheet revision 206326B.
Can SI8232DB-D-IS drive GaN FETs?
Yes - SI8232DB-D-IS can drive enhancement-mode GaN FETs requiring ≤0.5 A peak gate current and 0–6 V gate swing, provided external gate resistors and negative turn-off bias (if needed) are implemented. Its 45 ns propagation delay and <1 ns skew support high-frequency GaN operation up to 1 MHz, though layout parasitics must be minimized for optimal performance.
