Product details
Overview
SI8230BD-ASR from Skyworks Solutions is an automotive-grade, high-side/low-side isolated gate driver IC with 0.5 A peak output current, 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 traction inverters and onboard chargers.
For engineers reviewing the SI8230BD-ASR datasheet, SI8230BD-ASR pinout, SI8230BD-ASR application, or SI8230BD-ASR equivalent, this page delivers verified specifications, automotive-qualified package details (SOIC-16 wide body), functional truth table behavior, UVLO thresholds (8 V), and real-world design implications for isolated gate drive reliability and timing safety.
Technical Context
The SI8230BD-ASR implements RF-based silicon isolation with a semiconductor barrier, enabling 45 ns propagation delay and immunity to magnetic fields-unlike optocoupler-based alternatives. Its two independent isolated channels support high-side and low-side switching with synchronized dead-time control via external resistor (RDT) and built-in overlap protection logic.
It operates across –40 °C to +125 °C with separate input (VDDI) and output (VDDA/VDDB) supplies up to 24 V, and features independent undervoltage lockout on all three supply rails (VDDI, VDDA, VDDB), each with 8 V turn-on and hysteresis for robust startup/shutdown sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS per UL1577 - enables reinforced insulation for automotive traction inverters and OBCs meeting 2 MOPP requirements. |
| Peak Output Current | 0.5 A - sufficient to drive medium-power MOSFETs/IGBTs in <1 kW motor control and DC-DC stages without external buffers. |
| Propagation Delay | 45 ns max - ensures precise timing alignment between high-side and low-side outputs for <8 MHz switching frequencies. |
| UVLO Threshold | 8 V (VDDI, VDDA, VDDB) - prevents erratic gate drive during brown-out conditions and supports stable bootstrap startup. |
| Dead Time Programmability | Resistor-adjustable (RDT) - allows fine-tuned control of cross-conduction prevention in half-bridge topologies. |
| Input Logic | TTL-compatible with >400 mV hysteresis - rejects noise on VIA/VIB inputs in electric vehicle EMI environments. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive applications including battery management systems and charging stations. |
Pinout & Package
SI8230BD-ASR is housed in a RoHS-compliant SOIC-16 wide-body package (10.3 mm × 10.3 mm, 2.65 mm height) with creepage ≥8.3 mm and clearance ≥8.3 mm, certified for 5 kVRMS isolation per UL1577.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Input-side power supply | Supplies isolated input logic die; must be ≥8 V to exit UVLO and enable signal transmission. |
| GNDI | Input-side ground reference | Reference for VIA/VIB inputs and internal oscillator; galvanically isolated from output grounds. |
| VIA | High-side input control | TTL-compatible logic input; high state drives VOA high after dead time, subject to overlap protection. |
| VIB | Low-side input control | TTL-compatible logic input; high state drives VOB high after dead time, subject to overlap protection. |
| DISABLE | Global output disable | Active-high signal forcing both VOA and VOB low unconditionally, used for fault shutdown. |
| VDDA | High-side output supply | Power for VOA driver stage; independent UVLO monitoring prevents high-side misfire during rail collapse. |
| VOA | High-side gate drive output | Source/sink capable output driving N-channel MOSFET/IGBT gates in high-side configuration. |
| GNDA | High-side output ground | Return path for VOA; floats with high-side switching node and must be connected to source of high-side device. |
| VDDB | Low-side output supply | Power for VOB driver stage; independent UVLO monitoring ensures safe low-side operation. |
| VOB | Low-side gate drive output | Source/sink capable output driving N-channel MOSFET/IGBT gates referenced to system ground. |
| GNDB | Low-side output ground | System ground reference for VOB; tied directly to PCB ground plane in standard half-bridge layouts. |
| DT | Dead time programming | Connects to ground via RDT to set dead time (DT ≈ 10 × RDT ns); floating or tied to VDDI yields ~400 ps nominal. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated drivers in one SOIC-16 | Eliminates need for two discrete isolators in half-bridge designs, reducing BOM count and PCB area by >30% vs. optocoupler + driver combos. |
| Programmable dead time with overlap protection | Prevents shoot-through in real time using hardware logic-no MCU intervention required-critical for functional safety compliance (ISO 26262 ASIL-B). |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C ambient, with PPAP documentation, IMDS/CAMDS support, and zero-defect manufacturing flow. |
| RF-based silicon isolation | Delivers 45 ns propagation delay and superior CMTI (>35 kV/µs) vs. capacitive or transformer-based isolators, ensuring robustness in high-dv/dt EV power stages. |
| Independent triple-rail UVLO | Monitors VDDI, VDDA, and VDDB separately-prevents partial operation and undefined output states during asymmetric supply faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side isolated gate drive applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8230BD-D-IS | Industrial-grade version (–I suffix); identical electrical specs but lacks AEC-Q100 qualification, PPAP, and automotive traceability. | Approved for industrial inverters and UPS, not automotive safety-critical systems. | Select when automotive qualification is unnecessary and cost sensitivity outweighs long-term supply assurance. |
| UCC5390SCD | TI part with 4 A peak output, integrated Miller clamp, and higher CMTI (150 kV/µs), but no programmable dead time or overlap protection logic. | Suited for high-current SiC gate drive where shoot-through prevention relies on controller-level timing. | Choose when higher drive strength is needed and dead time is managed externally; not drop-in compatible due to different pinout and feature set. |
Compared with SI8230BD-ASR, Si8230BD-D-IS offers identical performance without automotive validation, while UCC5390SCD trades hardware-based overlap protection for higher drive strength and CMTI-making SI8230BD-ASR uniquely suited for ASIL-B-compliant automotive half-bridge control where deterministic shoot-through prevention is mandatory.

FAQ
What is the isolation voltage rating of SI8230BD-ASR and which safety standards does it meet?
The SI8230BD-ASR provides 5 kVRMS input-to-output isolation per UL1577, certified for reinforced insulation under CSA 62368-1 and 60601-1 (2 MOPP), VDE 60747-17 (basic), and CQC GB4943.1. This rating enables its use in high-voltage automotive systems such as onboard chargers and traction inverters where galvanic separation between control and power domains is mandated.
Does SI8230BD-ASR support programmable dead time, and how is it configured?
Yes, SI8230BD-ASR supports hardware-programmable dead time via an external resistor (RDT) connected from the DT pin to ground. Dead time is calculated as DT ≈ 10 × RDT (ns). A 0.1 µF capacitor placed near the DT pin improves noise immunity. The SI8230BD-ASR also includes built-in overlap protection that forces outputs low if both VIA and VIB go high simultaneously.
What are the UVLO thresholds for SI8230BD-ASR, and how do they affect system startup?
SI8230BD-ASR has independent 8 V UVLO thresholds on VDDI, VDDA, and VDDB. All three supplies must exceed 8 V before outputs become active. During startup, VOA and VOB remain low until VDDI rises above UVLO+, then follow VIA/VIB after tSTART. This prevents spurious switching during power ramp-up and ensures coordinated initialization across isolated domains.
How does SI8230BD-ASR differ from industrial-grade Si8230BD-D-IS?
SI8230BD-ASR is the automotive-grade variant: it shares identical electrical parameters and SOIC-16 wide-body packaging with Si8230BD-D-IS but adds AEC-Q100 Grade 1 qualification, AIAG-compliant PPAP documentation, IMDS/CAMDS material reporting, and zero-defect manufacturing controls. These ensure reliability in automotive safety-critical applications where Si8230BD-D-IS is not approved.
Can SI8230BD-ASR drive both MOSFETs and IGBTs, and what is its maximum recommended switching frequency?
Yes, SI8230BD-ASR can drive both N-channel MOSFETs and IGBTs with its 0.5 A peak source/sink capability and rail-to-rail output swing. Its 45 ns propagation delay and fast rise/fall times support switching frequencies up to 8 MHz-ideal for SiC-based topologies in modern EV power systems where timing precision and noise immunity are critical.
