Product details
Overview
SI8230BB-ASR 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, operates up to 24 V supply, and targets half-bridge MOSFET/IGBT drive in power inverters and motor controls.
For engineers reviewing the SI8230BB-ASR datasheet, SI8230BB-ASR pinout, SI8230BB-ASR application, or SI8230BB-ASR equivalent, this page delivers verified specifications, automotive-grade qualification status, isolation barrier performance, UVLO thresholds, and real-world use context for industrial and automotive power systems.
Technical Context
The SI8230BB-ASR implements RF-based silicon isolation with a semiconductor barrier, delivering 45 ns typical propagation delay and >400 mV input hysteresis. Its two independent isolated channels support high-side/low-side switching with internal dead time control via external resistor (RDT) and automatic overlap recovery.
It features separate undervoltage lockout (UVLO) monitors on input (VDDI), high-side (VDDA), and low-side (VDDB) supplies - each with 8 V turn-on and 7.5 V turn-off thresholds - ensuring safe startup/shutdown sequencing in isolated power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.5 kVRMS per UL1577 - enables reinforced insulation in 230 VAC mains-connected inverters and onboard chargers |
| Peak Output Current | 0.5 A - sufficient to drive 1200 V/30 A IGBTs or 650 V/40 A MOSFETs at ≤100 kHz switching |
| Propagation Delay | 45 ns max - supports >8 MHz PWM operation with tight timing margins in digital control loops |
| UVLO Threshold | 8 V (rising), 7.5 V (falling) - prevents erratic gate drive during brown-out conditions in battery-fed systems |
| Supply Voltage Range | 4.5–24 V on all rails (VDDI/VDDA/VDDB) - compatible with 5 V logic, 12 V auxiliary, and 24 V industrial bus supplies |
| Operating Temperature | –40 °C to +125 °C - validated for under-hood automotive and industrial ambient environments |
| AEC-Q100 Grade | Qualified to Grade 1 - meets automotive reliability requirements for traction inverters and OBCs |
Pinout & Package
SI8230BB-ASR is housed in a RoHS-compliant SOIC-16 wide-body package with 2.54 mm pitch and creepage/clearance optimized for 2.5 kVRMS isolation. Pin 1 is marked with a dot; pin numbering follows standard SOIC convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Input-side power supply | Provides 4.5–24 V to isolated input die; powers internal oscillator and logic |
| GNDI | Input-side ground reference | Return path for VIA/VIB inputs and DISABLE; galvanically separated from output grounds |
| VIA | High-side input signal | TTL-compatible logic input controlling VOA; >400 mV hysteresis rejects noise on PCB traces |
| VIB | Low-side input signal | TTL-compatible logic input controlling VOB; independent of VIA with no cross-talk |
| DISABLE | Global shutdown control | Active-high signal forcing both outputs low within 100 ns; overrides all input states |
| VDDA | High-side output power supply | Drives VOA; UVLO monitoring ensures gate drive only when rail is stable |
| VOA | High-side gate driver output | Sources/sinks 0.5 A; connects directly to MOSFET/IGBT gate; referenced to GNDA |
| GNDA | High-side output ground | Return for VOA and VDDA; electrically isolated from GNDI and GNDB |
| VDDB | Low-side output power supply | Drives VOB; independent UVLO prevents shoot-through during supply faults |
| VOB | Low-side gate driver output | Sources/sinks 0.5 A; referenced to GNDB; complements VOA in half-bridge topology |
| GNDB | Low-side output ground | Return for VOB and VDDB; isolated from GNDA and GNDI |
| DT | Dead time programming | Accepts external resistor to set 0–1000 ns dead time; tied to VDDI for ~400 ps default |
| NC | No connect | Pins 13 and 14 are unconnected; must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated drivers in one SOIC-16 | Eliminates need for two discrete optocouplers + gate drivers, reducing BOM count and PCB area by >40% |
| Programmable dead time with overlap protection | Prevents shoot-through in half-bridge configurations without requiring external logic or timers |
| RF-based silicon isolation barrier | Delivers 45 ns propagation delay and superior CMTI (>100 kV/µs) vs. optocoupler-based alternatives |
| Independent UVLO on all three supply domains | Ensures safe power-up sequencing and fault containment across isolated domains |
| AEC-Q100 qualified automotive grade | Validated for automotive applications including onboard chargers and traction inverters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8230BD-ASR | 5.0 kVRMS isolation rating; same pinout and functionality | Required for 400/480 VAC industrial systems needing reinforced insulation per IEC 62368-1 | Select when higher isolation voltage is mandated by safety standards or system architecture |
| UCC5350MCDWVR | TI's 2.5 kVRMS isolated driver with 4 A peak output; different pinout and no programmable dead time | Used where higher drive strength is needed for fast-switching GaN FETs, but requires external dead time logic | Choose when driving high-Qg devices at >500 kHz, accepting added design complexity for higher current |

FAQ
What is the isolation voltage rating of the SI8230BB-ASR?
The SI8230BB-ASR has a certified 2.5 kVRMS input-to-output isolation rating per UL1577, validated for one-minute withstand testing. This rating supports reinforced insulation in 230 VAC-connected equipment and meets CSA 62368-1 requirements for industrial power supplies and EV charging systems.
Does the SI8230BB-ASR support programmable dead time?
Yes, the SI8230BB-ASR includes a dedicated DT pin that accepts an external resistor to set dead time from 0 to 1000 ns. When left floating or tied to VDDI, it defaults to approximately 400 ps. This feature is integral to preventing shoot-through in half-bridge configurations without external logic.
Is the SI8230BB-ASR qualified for automotive applications?
Yes, the SI8230BB-ASR is an automotive-grade part (denoted by "-AS" suffix) and is AEC-Q100 qualified to Grade 1 (–40 °C to +125 °C). It is manufactured using automotive-specific process flows and supported with AIAG-compliant PPAP documentation.
What are the UVLO thresholds for the SI8230BB-ASR?
The SI8230BB-ASR features independent UVLO on VDDI, VDDA, and VDDB rails, each with a rising threshold of 8 V and falling threshold of 7.5 V. Outputs remain low until all enabled supplies exceed their respective UVLO+, ensuring safe startup and fault containment.
Can the SI8230BB-ASR drive both MOSFETs and IGBTs?
Yes, the SI8230BB-ASR's 0.5 A peak source/sink current and 24 V maximum supply support gate driving for medium-power MOSFETs (e.g., 650 V/40 A) and IGBTs (e.g., 1200 V/30 A) in hard-switched topologies up to 100 kHz, with appropriate external gate resistors.
