Product details
Overview
SI8230AC-D-IS1 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-input control (VIA/VIB). It integrates programmable dead time and overlap protection, operates up to 8 MHz switching frequency, and supports industrial motor control and isolated DC-DC power supplies.
For engineers reviewing the SI8230AC-D-IS1 datasheet, SI8230AC-D-IS1 pinout, SI8230AC-D-IS1 application, or SI8230AC-D-IS1 equivalent, this page delivers verified specifications, package mapping, functional context, real-world use cases, and validated alternative options for half-bridge MOSFET/IGBT drive in high-reliability power systems.
Technical Context
The SI8230AC-D-IS1 implements RF-based silicon isolation with a semiconductor barrier, delivering 45 ns typical propagation delay and >400 mV input hysteresis for noise immunity. Its two independent isolated channels support high-side and low-side gate drive with separate VDDA/VDDB supplies and shared VDDI logic supply.
It features integrated undervoltage lockout (UVLO) on all three supply rails (VDDI = 5 V threshold, VDDA/VDDB = 5 V), programmable dead time via external resistor (DT pin), and automatic overlap protection that forces both outputs low during simultaneous high inputs - critical for preventing shoot-through in half-bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.75 kVRMS per UL1577 - enables safe operation across reinforced insulation barriers in 600–1000 V bus applications. |
| Peak Output Current | 0.5 A - sufficient to drive medium-power MOSFETs/IGBTs with gate charge ≤30 nC at ≤100 kHz switching. |
| Propagation Delay | 45 ns max - ensures precise timing alignment between high-side and low-side signals in fast-switching converters. |
| Switching Frequency | Up to 8 MHz - supports high-frequency resonant topologies including LLC and GaN-based designs. |
| UVLO Threshold | VDDI = 5 V (rising), VDDA/VDDB = 5 V - prevents erratic gate drive during brown-out or soft-start conditions. |
| Input Compatibility | TTL-level with >400 mV hysteresis - rejects noise on control lines in electrically noisy motor drive or inverter environments. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions without derating. |
Pinout & Package
SI8230AC-D-IS1 is housed in a RoHS-compliant SOIC-16 narrow-body package (5.3 mm width), rated for 260 °C peak reflow per JEDEC J-STD-020. Creepage and clearance meet reinforced insulation requirements for 3.75 kVRMS isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Input-side ground and supply | GNDI and VDDI pins form isolated logic domain; VDDI powers internal oscillator/modulator (4.5–5.5 V). |
| 9, 10 | Control inputs | VIA and VIB accept TTL-level signals; high-true logic drives corresponding outputs high. |
| 11 | Disable input | Active-high DISABLE forces VOA and VOB low unconditionally - used for fault shutdown or soft-start sequencing. |
| 12, 13 | Output drivers | VOA (high-side) and VOB (low-side) each deliver 0.5 A peak into capacitive gate loads; independent VDDA/VDDB supplies. |
| 14, 15, 16 | Output-side supplies/grounds | VDDA, VDDB, GNDA, GNDB provide isolated power domains for driver outputs; GNDA/GNDB may be tied or separated. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated gate drivers | Two independent 3.75 kVRMS-isolated channels in one SOIC-16 package - eliminates need for two discrete optocouplers or isolated transformers. |
| Programmable dead time | Configurable via external resistor (DT pin); 0–1000 ns range - prevents shoot-through without requiring external timing circuitry. |
| Overlap protection | Hardware-enforced logic blocks simultaneous high outputs - guarantees safe turn-off before turn-on in half-bridge configurations. |
| RF isolation architecture | Silicon-based barrier replaces LED/photodiode; achieves 45 ns propagation delay and superior CMTI (>35 kV/µs) vs. optocouplers. |
| AEC-Q100 qualified | Automotive-grade variant available (SI8230AC-AS1); full PPAP, IMDS/CAMDS support - suitable for OBC, BMS, and traction inverter subsystems. |

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-IS1 | Same SOIC-16 narrow-body package, but 5 V UVLO threshold raised to 8 V; 5.0 kVRMS isolation rating. | Better suited for higher-bus industrial systems requiring stricter isolation margin (e.g., 1200 V DC bus). | Select when system-level safety certification demands 5.0 kVRMS UL1577 rating and higher UVLO hysteresis improves noise immunity. |
| UCC21520DWR | Texas Instruments part with dual 4-A output, 5.7 kVRMS isolation, and integrated Miller clamp; SOIC-16 wide-body package. | Higher drive strength supports faster switching of larger GaN/SiC devices; Miller clamp reduces risk of false turn-on. | Choose when driving >100 nC gate charges or requiring active Miller clamping in high-dV/dt environments like traction inverters. |
Compared with SI8230BD-D-IS1, SI8230AC-D-IS1 offers lower UVLO (5 V vs. 8 V) and reduced isolation (3.75 kV vs. 5.0 kV), trading margin for compatibility with 5 V logic systems; versus UCC21520DWR, it provides lower cost and smaller footprint but lacks Miller clamping and higher peak current.

FAQ
What is the isolation voltage rating of SI8230AC-D-IS1?
The SI8230AC-D-IS1 has a certified 3.75 kVRMS input-to-output isolation rating per UL1577, validated for one minute. This rating applies to the SOIC-16 narrow-body package and supports reinforced insulation in systems with working voltages up to 1000 V DC, meeting key safety standards for industrial and automotive power electronics.
Does SI8230AC-D-IS1 support programmable dead time?
Yes, SI8230AC-D-IS1 supports programmable dead time via an external resistor connected to the DT pin. The dead time (DT) is calculated as DT ≈ 10 × RDT (ns), where RDT is in kΩ. A 0.1 µF ceramic capacitor placed near the DT pin enhances noise immunity. Nominal dead time (~400 ps) occurs when DT is tied to VDDI or left floating.
What is the UVLO threshold for SI8230AC-D-IS1?
The SI8230AC-D-IS1 has a 5 V rising threshold (UVLO+) for VDDI, VDDA, and VDDB supplies. Outputs remain low until all three supplies exceed 5 V, after which normal operation begins. This 5 V UVLO setting ensures reliable startup in 5 V logic systems and improves noise margin over 3.3 V alternatives.
Can SI8230AC-D-IS1 drive both high-side and low-side MOSFETs in a half-bridge?
Yes, SI8230AC-D-IS1 is explicitly designed as a high-side/low-side isolated driver. Its VOA output drives the high-side switch (e.g., bootstrap-fed N-channel MOSFET), while VOB drives the low-side switch. Integrated overlap protection and programmable dead time prevent shoot-through - making SI8230AC-D-IS1 ideal for half-bridge, three-phase inverter, and resonant converter topologies.
Is SI8230AC-D-IS1 qualified for automotive applications?
The SI8230AC-D-IS1 is an industrial-grade part, but its automotive-grade counterpart SI8230AC-AS1 is AEC-Q100 qualified and supported with AIAG-compliant PPAP documentation, IMDS, and CAMDS listings. While SI8230AC-D-IS1 shares identical electrical specs and construction, only the "-AS1" suffix version is approved for automotive production use in OBC, BMS, and traction inverter subsystems.
