Product details
Overview
SI8230AD-D-ISR from Skyworks Solutions is a 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 features programmable dead time, overlap protection, and 5 V undervoltage lockout (UVLO) threshold, designed for half-bridge MOSFET/IGBT drive in industrial inverters and motor control systems.
For engineers reviewing the SI8230AD-D-ISR datasheet, SI8230AD-D-ISR pinout, SI8230AD-D-ISR application, or SI8230AD-D-ISR equivalent, this page delivers verified electrical specs, SOIC-14 wide-body package details, functional truth table behavior, automotive-grade qualification status, and real-world design implications of its RF-based isolation architecture and dual-channel timing control.
Technical Context
The SI8230AD-D-ISR implements two independent, galvanically isolated gate drivers using Skyworks' proprietary silicon RF isolation barrier-replacing optocouplers with 45 ns propagation delay, 8 MHz max switching frequency, and immunity to magnetic fields. Its internal dead time control (via external RDT) and overlap protection logic prevent shoot-through in half-bridge topologies.
Each channel operates with separate supply domains: VDDI (input side), VDDA/VDDB (output sides), enabling floating high-side drive. UVLO monitors on all three supplies (VDDI = 5 V threshold, VDDA/VDDB = 5 V threshold) ensure safe power-up/down sequencing and fault containment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation rating | 5.0 kVRMS per UL1577 - enables reinforced insulation in 1500 VDC bus systems without additional creepage barriers |
| Peak output current | 0.5 A - sufficient to drive 1200 V/30 A IGBTs or 650 V/50 A MOSFETs with <100 ns rise/fall times under 100 pF load |
| Propagation delay | 45 ns max - ensures tight timing alignment between high-side and low-side outputs for <100 ns dead time precision |
| UVLO threshold | 5 V (VDDI, VDDA, VDDB) - prevents erratic switching during brown-out conditions common in industrial power rails |
| Switching frequency | Up to 8 MHz - supports high-frequency resonant LLC and GaN-based converters requiring fast gate transitions |
| Input compatibility | TTL-level with >400 mV hysteresis - rejects noise in noisy motor drive environments without external Schmitt triggers |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions |
Pinout & Package
SI8230AD-D-ISR is housed in a RoHS-compliant SOIC-14 wide-body package with increased creepage, optimized for 5 kVRMS isolation and high-voltage PCB layout. Pin spacing meets IPC-2221B Class B requirements for 500 V working voltage across isolation barrier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Input-side supply | Provides power to RF transmitter and logic; must be ≥5 V to exit UVLO and enable output operation |
| GNDI | Input-side ground | Reference for VIA/VIB inputs and DISABLE; electrically isolated from GNDA/GNDB |
| VIA | High-side input | TTL-compatible signal controlling VOA; high-true logic with 400 mV hysteresis for noise margin |
| VIB | Low-side input | TTL-compatible signal controlling VOB; independent of VIA, enabling asymmetric PWM or phase-shifted control |
| DISABLE | Global shutdown | Active-high input forcing both VOA and VOB low within tSD ≤ 100 ns; no effect if VDDI < UVLO |
| VDDA | High-side output supply | Power source for VOA driver; UVLO monitoring ensures safe turn-off during supply sag |
| VOA | High-side gate output | Source/sink capable driver referenced to GNDA; drives gate of high-side switch in half-bridge |
| GNDA | High-side output ground | Return path for VOA; floats with high-side switch node; requires proper bootstrap or isolated supply |
| VDDB | Low-side output supply | Power source for VOB driver; shares same UVLO threshold as VDDA and VDDI |
| VOB | Low-side gate output | Source/sink capable driver referenced to GNDB; directly tied to system ground in standard half-bridge |
| GNDB | Low-side output ground | System ground reference for VOB; electrically isolated from GNDI and GNDA |
| DT | Dead time programming | Connects to ground via resistor RDT to set dead time (DT ≈ 10 × RDT ns); floating = ~400 ps nominal |
| NC | No connect | Internally unused pin; must remain unconnected per datasheet to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated drivers in one SOIC-14 | Eliminates need for two discrete isolators and gate drivers, reducing BOM count and PCB area by >40% vs. optocoupler+driver solutions |
| RF-based isolation barrier | Delivers 45 ns propagation delay and superior CMTI (>100 kV/µs) vs. capacitive or transformer-based isolators |

| AEC-Q100 qualified (automotive-grade variant) | Validated for automotive applications including onboard chargers and traction inverters; supported by AIAG PPAP documentation |
| 5 V UVLO on all supplies | Ensures coordinated shutdown across input and both output domains during partial power loss, preventing latch-up or undefined states |
| SOIC-14 wide-body with enhanced creepage | Meets reinforced insulation requirements for 1500 VDC systems without conformal coating or slotting |

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 | Same SOIC-14 package and 0.5 A/5 kVRMS specs, but 8 V UVLO threshold instead of 5 V | Better suited for 12 V input rail systems where tighter UVLO margin is not required | Select SI8230AD-D-ISR when operating from 5 V logic rails or requiring lower UVLO for brown-out resilience |
| UCC21520DWR | TI part with 4 A peak output, 5 kVRMS, SOIC-16 package; higher drive strength but no programmable dead time | Requires external dead time circuitry for half-bridge use; better for high-current GaN/SiC applications | Choose SI8230AD-D-ISR when integrated dead time, smaller SOIC-14 footprint, and TTL input compatibility are prioritized over raw drive current |
Compared with Si8230BD-D-IS, SI8230AD-D-ISR offers lower UVLO for improved robustness on 5 V supplies; compared with UCC21520DWR, it trades peak current for integrated timing control and compact packaging-making it optimal for space-constrained, medium-power industrial inverters.

FAQ
What is the isolation voltage rating of the SI8230AD-D-ISR?
The SI8230AD-D-ISR provides 5.0 kVRMS input-to-output isolation per UL1577, validated for one-minute withstand. This rating applies across the full operating temperature range (–40 °C to +125 °C) and supports reinforced insulation in systems with up to 1500 VDC bus voltages, as confirmed in Skyworks' safety certification documentation.
Does the SI8230AD-D-ISR support programmable dead time?
Yes, the SI8230AD-D-ISR includes a dedicated DT pin that accepts an external resistor (RDT) to set dead time per Equation 1: DT ≈ 10 × RDT (ns). With RDT = 10 kΩ, dead time is ~100 ns; floating the pin yields ~400 ps nominal. This feature is integral to the SI8230AD-D-ISR's overlap protection architecture.
What is the UVLO threshold for the SI8230AD-D-ISR?
The SI8230AD-D-ISR has a 5 V undervoltage lockout (UVLO) threshold on all three supply pins: VDDI, VDDA, and VDDB. The device remains in reset until each supply exceeds 5 V, and outputs default low if any supply falls below this threshold-ensuring fail-safe behavior during brown-out events in the SI8230AD-D-ISR's operational domain.
Is the SI8230AD-D-ISR pin-compatible with other Si823x variants?
No-SI8230AD-D-ISR uses the SOIC-14 wide-body package with increased creepage, while many Si823x variants (e.g., Si8230BD-D-IS) use SOIC-16. Pin count, pinout, and creepage distances differ; direct PCB replacement is not possible without layout revision. Always verify package dimensions and pin mapping before substitution involving the SI8230AD-D-ISR.
What input logic levels does the SI8230AD-D-ISR accept?
The SI8230AD-D-ISR accepts TTL-compatible inputs on VIA and VIB with >400 mV hysteresis, supporting logic-high thresholds from 2.0 V to VDDI and logic-low thresholds up to 0.8 V. This ensures reliable operation with standard 3.3 V or 5 V microcontrollers without level-shifting, a key specification confirmed in the SI8230AD-D-ISR datasheet Section 2.6.3.
