Product details
Overview
SI8230AC-D-IS1R from Skyworks Solutions is a high-side/low-side isolated gate driver IC with 0.5 A peak output current, 3.75 kVRMS input-to-output isolation, and TTL-compatible dual inputs (VIA/VIB). It integrates two independent isolated drivers in a single SOIC-16 narrow-body package and features programmable dead time, overlap protection, and 45 ns propagation delay - enabling robust half-bridge control in industrial inverters and motor drives.
For engineers reviewing the SI8230AC-D-IS1R datasheet, SI8230AC-D-IS1R pinout, SI8230AC-D-IS1R application, or SI8230AC-D-IS1R equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The SI8230AC-D-IS1R implements RF-based on/off keying across a proprietary silicon isolation barrier, delivering galvanic separation without optical degradation or magnetic sensitivity. Its dual-channel architecture supports independent high-side and low-side gate drive with integrated UVLO monitoring per side (5 V threshold) and a dedicated DISABLE input that forces both outputs low within tSD.
This variant belongs to the Si8230 subfamily: two-input, high-side/low-side configuration with programmable dead time via external resistor (DT pin), overlap protection logic, and operation across –40°C to +125°C. It does not support PWM input mode (reserved for Si8231/Si8234) and lacks dual-driver functionality (Si8232/Si8235).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.75 kVRMS - meets reinforced insulation requirements for industrial systems up to 1000 VDC bus voltage. |
| Peak Output Current | 0.5 A - sufficient to drive MOSFETs/IGBTs with gate charge ≤25 nC at ≤100 kHz switching frequency. |
| Propagation Delay | 45 ns - enables precise timing control in high-frequency half-bridge topologies with minimal shoot-through risk. |
| UVLO Threshold | 5 V (VDDI) - ensures reliable startup and shutdown behavior in 5 V logic-controlled systems. |
| Supply Voltage Range | 4.5–24 V (VDDA/VDDB) - supports direct connection to standard gate-drive supply rails without LDO buffering. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive auxiliary systems and industrial power converters. |
| Package | SOIC-16 narrow body - footprint-compatible with legacy SOIC-16 layouts while providing 3.75 kVRMS creepage/clearance. |
Pinout & Package
SI8230AC-D-IS1R uses a RoHS-compliant SOIC-16 narrow-body package (5.3 mm width) with 1.27 mm pitch, rated for 260 °C peak reflow per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GNDI | Input-side ground reference | Return path for VIA, VIB, DISABLE, DT, and VDDI - must be separated from power-side grounds to maintain isolation integrity. |
| VIA | High-side input signal | TTL-compatible logic input controlling VOA; high-true, >400 mV hysteresis prevents noise-induced transitions. |
| VIB | Low-side input signal | TTL-compatible logic input controlling VOB; independent of VIA, enabling asymmetric drive timing. |
| DISABLE | Global output disable control | Active-high signal forcing VOA/VOB low regardless of VIA/VIB state - used for fault shutdown or soft-start sequencing. |
| DT | Dead time programming node | Connects to external resistor (RDT) to set dead time (DT ≈ 10 × RDT ns); floating or tied to VDDI yields ~400 ps nominal dead time. |
| VDDI | Input-side supply | 4.5–5.5 V supply powering input logic and isolation transmitter; UVLO triggers at 5 V (rising) / 4.5 V (falling). |
| VDDA | High-side driver supply | 4.5–24 V supply for VOA output stage; independent UVLO (5 V) ensures safe high-side gate drive only when valid. |
| VOA | High-side gate drive output | 0.5 A source/sink capable output referenced to GNDA; designed to drive N-channel MOSFET/IGBT gates in bootstrap configurations. |
| GNDA | High-side driver ground | Return for VOA and VDDA - floats with high-side switching node; must be isolated from GNDB and GNDI. |
| VDDB | Low-side driver supply | 4.5–24 V supply for VOB; independent UVLO ensures low-side gate drive remains active only during valid supply conditions. |
| VOB | Low-side gate drive output | 0.5 A source/sink output referenced to GNDB; directly drives low-side switch with fast edge rates and low propagation skew. |
| GNDB | Low-side driver ground | Return for VOB and VDDB - typically connected to system power ground; electrically isolated from GNDA and GNDI. |
| VDDI (Pin 16) | Input-side supply (redundant) | Second VDDI pin for improved decoupling and reduced input-side supply impedance - must be bypassed with 0.1 µF ceramic capacitor. |
| GNDI (Pin 15) | Input-side ground (redundant) | Second GNDI pin for lower input-side ground impedance - connects to same net as Pin 1 to minimize noise coupling into isolation barrier. |
| NC | No connect | Pins 7 and 8 are unconnected - must remain floating per datasheet; no internal circuitry attached. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated drivers in one SOIC-16 | Reduces PCB area by >40% vs. discrete optocoupler + gate driver solutions while maintaining 3.75 kVRMS isolation. |
| Programmable dead time with overlap protection | Prevents simultaneous conduction in half-bridge legs using user-configurable resistor (RDT), eliminating external timing ICs. |
| RF-based isolation architecture | Delivers 45 ns propagation delay and superior CMTI (>35 kV/µs) vs. optocouplers, with no LED aging or temperature drift. |
| TTL-compatible inputs with 400 mV hysteresis | Accepts standard microcontroller GPIO outputs directly - no level-shifting or Schmitt-trigger buffers required. |
| Independent UVLO per power domain | Monitors VDDI, VDDA, and VDDB separately - ensures safe gate drive only when all supplies meet minimum thresholds. |
| AEC-Q100 qualified (automotive-grade version) | Industrial-grade SI8230AC-D-IS1R shares identical construction and electrical specs with automotive OPN SI8230AC-AS1, enabling qualification reuse. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8230BD-D-IS1R | Same SOIC-16 narrow-body package, but 5 V UVLO threshold raised to 8 V; 5.0 kVRMS isolation rating. | Better suited for 24 V input logic systems or higher-isolation industrial safety requirements (e.g., UL 62368-1 Class II). | Select SI8230BD-D-IS1R when system-level isolation certification requires ≥5.0 kVRMS or VDDI operates above 5.5 V. |

FAQ
What is the isolation voltage rating of the SI8230AC-D-IS1R?
The SI8230AC-D-IS1R has a certified 3.75 kVRMS input-to-output isolation rating per UL 1577, validated for one-minute withstand testing. This rating supports reinforced insulation in systems with working voltages up to 1000 VDC and meets IEC 62368-1 requirements for industrial power equipment.
Does the SI8230AC-D-IS1R support PWM input mode?
No, the SI8230AC-D-IS1R does not support PWM input mode. It is a two-input high-side/low-side driver (VIA/VIB configuration) per the Si8230 family designation. PWM input functionality is exclusive to Si8231 and Si8234 variants, which use a single PWM pin to derive complementary outputs.
What is the purpose of the DT pin on the SI8230AC-D-IS1R?
The DT pin on the SI8230AC-D-IS1R sets programmable dead time between VOA and VOB transitions using an external resistor (RDT). Dead time = 10 × RDT (ns). Floating or tying DT to VDDI yields ~400 ps nominal dead time. A 0.1 µF capacitor must be placed close to DT for noise immunity.
Can the SI8230AC-D-IS1R drive SiC or GaN MOSFETs?
Yes, the SI8230AC-D-IS1R can drive SiC and GaN MOSFETs with gate charges ≤25 nC at switching frequencies up to 200 kHz. Its 0.5 A peak output, 45 ns propagation delay, and fast rise/fall times (<10 ns typical) support efficient gate control in high-speed power stages.
Is the SI8230AC-D-IS1R pin-compatible with other Si823x variants?
The SI8230AC-D-IS1R is pin-compatible with all Si8230-x variants in SOIC-16 narrow-body packaging (e.g., SI8230BD-D-IS1R, SI8230AB-D-IS1R), sharing identical pinout, footprint, and thermal characteristics. Differences are limited to UVLO threshold, isolation rating, and internal logic configuration.
