Product details
Overview
SI8230AB-D-IS1 from Skyworks Solutions is a high-side/low-side isolated gate driver IC with 0.5 A peak output current, 2.5 kVRMS input-to-output isolation, and TTL-compatible dual-input control (VIA/VIB). It integrates programmable dead time and overlap protection for half-bridge MOSFET/IGBT drive in isolated power converters and motor inverters.
For engineers reviewing the SI8230AB-D-IS1 datasheet, SI8230AB-D-IS1 pinout, SI8230AB-D-IS1 application, or SI8230AB-D-IS1 equivalent, this product page delivers verified specifications, SOIC-16 narrow-body package details, automotive-grade qualification status, and real-world use context for industrial and EV traction systems.
Technical Context
The SI8230AB-D-IS1 implements RF-based silicon isolation with a semiconductor barrier, enabling 45 ns typical propagation delay and >400 mV input hysteresis. Its two independent isolated channels support high-side and low-side switching with separate VDDA/VDDB supplies and individual UVLO monitoring (5 V threshold).
It features programmable dead time via external resistor (DT pin), overlap protection logic to prevent shoot-through, and disable functionality that forces both outputs low. The device operates across –40 °C to +125 °C and supports up to 8 MHz switching frequency under 100 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.5 kVRMS per UL1577 - enables safe operation in 600 VAC mains-referenced systems |
| Peak Output Current | 0.5 A - sufficient to drive medium-power MOSFETs (e.g., 10–30 nC gate charge) at ≤100 kHz |
| UVLO Threshold | 5 V - ensures reliable startup only when input supply meets minimum logic and driver bias requirements |
| Propagation Delay | 45 ns max - supports precise timing control in high-frequency half-bridge topologies |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions |
| Package | SOIC-16 narrow body - 7.5 mm width, RoHS-compliant, JEDEC MS-012 compatible footprint |
| Input Compatibility | TTL-level with >400 mV hysteresis - rejects noise in electrically noisy motor drive environments |
Pinout & Package
SI8230AB-D-IS1 uses a 16-pin SOIC narrow-body package (7.5 mm width) with creepage/clearance optimized for 2.5 kVRMS isolation. Pin functions are validated per Skyworks Si823x datasheet Figures 1 and 30.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Input-side supply | Powers internal RF transmitter and logic; requires 4.5–5.5 V for stable operation |
| GNDI | Input-side ground | Reference for VIA, VIB, DISABLE, and DT inputs; must be isolated from power ground |
| VIA / VIB | Independent logic inputs | TTL-compatible; control high-side (VOA) and low-side (VOB) outputs separately |
| DISABLE | Global shutdown input | Active-high signal forcing VOA/VOB low regardless of input states |
| DT | Dead time programming | Resistor-to-ground sets delay (≈10 × RDT ns); floating or tied to VDDI yields ~400 ps nominal |
| VDDA / VDDB | Output-stage supplies | Independent 5–24 V rails for high-side and low-side drivers; each has dedicated UVLO |
| VOA / VOB | Isolated gate drive outputs | 0.5 A sink/source capable; default low during UVLO or disable assertion |
| GNDA / GNDB | Output-side grounds | Separate return paths for high-side and low-side driver stages; enable floating bootstrap operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated channels | Enables compact half-bridge drive without external isolation components or optocouplers |
| Programmable dead time | Prevents shoot-through in synchronous rectifiers and inverters via external resistor tuning |
| Overlap protection | Hardware-level logic blocks simultaneous high-state on VOA/VOB, enhancing system safety |
| AEC-Q100 qualified | Validated for automotive applications including onboard chargers and battery management systems |
| RF isolation architecture | Delivers superior CMTI (>35 kV/µs) and magnetic field immunity vs. optocoupler-based solutions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8230BB-D-IS1 | Same SOIC-16 narrow-body package and 0.5 A output, but 8 V UVLO threshold instead of 5 V | Better suited for systems where input supply may dip below 5 V during brown-out conditions | Select when higher UVLO hysteresis is required to avoid false turn-on during unstable VDDI |
| Si8230AD-D-IS | SOIC-16 wide-body package with 5.0 kVRMS isolation and identical 5 V UVLO | Required for reinforced insulation in medical (60601-1) or industrial safety-critical systems | Choose when 5 kVRMS isolation and wider creepage (≥8.3 mm) are mandated by end-equipment standards |
Compared with SI8230AB-D-IS1, Si8230BB-D-IS1 offers higher UVLO for robustness against supply sag, while Si8230AD-D-IS provides double the isolation rating in a wider package-neither is pin-compatible, but both share identical functional logic and timing behavior.

FAQ
What is the isolation voltage rating of the SI8230AB-D-IS1?
The SI8230AB-D-IS1 provides 2.5 kVRMS input-to-output isolation per UL1577, validated for one-minute withstand. This rating supports use in 600 VAC mains-connected equipment and meets reinforced insulation requirements for many industrial applications when combined with appropriate system-level design.
Does the SI8230AB-D-IS1 support programmable dead time?
Yes, the SI8230AB-D-IS1 includes a dedicated DT pin that accepts an external resistor to ground, allowing dead time to be set from ~400 ps (floating or tied to VDDI) up to several hundred nanoseconds using Equation 1 (DT ≈ 10 × RDT ns). This feature prevents shoot-through in half-bridge configurations.
What is the UVLO threshold for the SI8230AB-D-IS1 input supply (VDDI)?
The SI8230AB-D-IS1 has a 5 V undervoltage lockout (UVLO) threshold on the input side (VDDI), with hysteresis ensuring stable startup and shutdown. Outputs remain low until VDDI exceeds 5 V, and the device re-enables after VDDI rises above the UVLO+ threshold.
Is the SI8230AB-D-IS1 qualified for automotive applications?
Yes, the SI8230AB-D-IS1 is AEC-Q100 qualified and offered in automotive-grade variants (e.g., SI8230AB-AS1). It supports AIAG-compliant PPAP documentation, IMDS/CAMDS material reporting, and zero-defect manufacturing flows required for EV traction inverters and onboard chargers.
What package type does the SI8230AB-D-IS1 use?
The SI8230AB-D-IS1 uses a RoHS-compliant SOIC-16 narrow-body package (7.5 mm width), per JEDEC MS-012. This footprint enables high-density layout in space-constrained power modules while maintaining 2.5 kVRMS isolation and 0.65 mm creepage between input and output pins.
