Product details
Overview
SI8230AD-D-IS3 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), designed for half-bridge MOSFET/IGBT drive in industrial inverters and motor control systems.
For engineers reviewing the SI8230AD-D-IS3 datasheet, SI8230AD-D-IS3 pinout, SI8230AD-D-IS3 application, or SI8230AD-D-IS3 equivalent, this page delivers verified specifications, SOIC-14 wide-body package details, functional truth table behavior, automotive-grade qualification status, and real-world design implications of its 45 ns propagation delay and 5 kVRMS reinforced insulation per UL1577.
Technical Context
The SI8230AD-D-IS3 implements RF-based on/off keying across a silicon isolation barrier-enabling robust noise immunity without startup initialization. Its two independent isolated channels support high-side and low-side gate drive with integrated dead-time control via external resistor (RDT) and automatic overlap recovery logic.
It operates across –40°C to +125°C with separate input (VDDI) and output (VDDA/VDDB) supplies, each monitored by dedicated UVLO circuits (5 V threshold). The DISABLE pin forces both outputs low unconditionally when asserted, with tSD shutdown and tRESTART recovery timing defined in the datasheet.

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-IS3 | Same SOIC-14 wide-body package and pinout; 8 V UVLO threshold instead of 5 V | Better suited for systems with higher input supply stability; less tolerant of 5 V rail droop during startup | Select SI8230BD-D-IS3 if VDDI is regulated ≥7.5 V; otherwise SI8230AD-D-IS3 ensures robust operation at nominal 5 V logic rails |
| UCC5390SCD | TI part with 4 A peak output, 3.75 kVRMS isolation, and integrated Miller clamp; different pinout and no DT pin | Targeted at higher-power GaN/SiC designs requiring active Miller clamping; lacks programmable dead time | Choose UCC5390SCD only when >1 A drive strength or Miller clamping is required; SI8230AD-D-IS3 offers superior isolation and timing flexibility for 0.5 A applications |
Compared with SI8230BD-D-IS3, SI8230AD-D-IS3 provides tighter UVLO matching to standard 5 V microcontroller I/O, while UCC5390SCD trades isolation robustness and dead-time configurability for higher drive strength and integrated protection-making SI8230AD-D-IS3 optimal for cost-sensitive, safety-critical 5 kVRMS industrial half-bridges.

FAQ
What is the maximum switching frequency supported by the SI8230AD-D-IS3?
The SI8230AD-D-IS3 supports up to 8 MHz switching frequency, enabled by its 45 ns maximum propagation delay and matched channel timing. This allows clean, jitter-free gate drive for high-frequency topologies such as resonant LLC converters and digital PFC stages where timing precision directly impacts efficiency and EMI performance. The SI8230AD-D-IS3 maintains this capability across its full operating temperature range (–40°C to +125°C).
Does the SI8230AD-D-IS3 require external components for basic operation?
Yes-the SI8230AD-D-IS3 requires external bypass capacitors on VDDI, VDDA, and VDDB (typically 100 nF ceramic each), plus a pull-up resistor on the DISABLE pin if not actively driven. For programmable dead time, a resistor (RDT) from DT pin to ground is needed; a 0.1 µF capacitor in parallel improves noise immunity. No external bootstrap diodes or level shifters are required, as isolation is fully integrated within the SI8230AD-D-IS3 die.
How does the SI8230AD-D-IS3 handle undervoltage conditions on its output supplies?
The SI8230AD-D-IS3 implements independent UVLO monitoring on VDDA and VDDB. If either falls below its 5 V threshold, the corresponding output (VOA or VOB) is forced low and held there until the supply recovers above UVLO+, preventing partial or erratic gate drive. This behavior is critical for protecting IGBTs/MOSFETs during bus voltage sag or startup sequencing-ensuring the SI8230AD-D-IS3 remains fail-safe even when only one output supply is compromised.
Can the SI8230AD-D-IS3 be used in automotive applications?
Yes-while SI8230AD-D-IS3 is the industrial-grade version, its automotive counterpart SI8230AD-AS3 is AEC-Q100 qualified, manufactured in automotive-specific process flows, and supported with AIAG-compliant PPAP documentation, IMDS, and CAMDS listings. Both share identical electrical specs and pinout; SI8230AD-D-IS3 may be used in non-safety-critical automotive prototyping, but SI8230AD-AS3 is required for production deployment in OBCs, BMS, or traction inverters.
What isolation certifications does the SI8230AD-D-IS3 meet?
The SI8230AD-D-IS3 is UL 1577 recognized for 5000 VRMS isolation (1 minute), CSA certified to IEC 62368-1 (reinforced insulation) and IEC 60601-1 (2 MOPP), VDE compliant with IEC 60747-17 (basic insulation), and CQC approved to GB4943.1 (reinforced insulation). These certifications validate its suitability for medical, industrial, and grid-connected equipment where reinforced insulation is mandated by safety standards.
