Product details
Overview
SI8230AB-D-IS from Skyworks Solutions is a high-side/low-side isolated gate driver IC with 0.5 A peak output current, 2.5 kVRMS input-to-output isolation, and TTL-compatible dual inputs (VIA/VIB). It integrates programmable dead time and overlap protection for half-bridge MOSFET/IGBT control in isolated power stages, operating across –40°C to +125°C with 5 V UVLO threshold.
For engineers reviewing the SI8230AB-D-IS datasheet, SI8230AB-D-IS pinout, SI8230AB-D-IS application, or SI8230AB-D-IS equivalent, this page delivers verified specifications, SOIC-16 wide-body package details, functional truth table behavior, automotive-grade qualification status, and real-world use cases in solar inverters and onboard chargers - all grounded in Skyworks' official 206326B datasheet.
Technical Context
The SI8230AB-D-IS implements RF-based isolation using Skyworks' proprietary silicon barrier, enabling 45 ns typical propagation delay and immunity to magnetic fields without optical degradation. Its two independent isolated channels support high-side/low-side switching with internal dead-time control via external resistor (RDT) and automatic overlap recovery.
It features separate undervoltage lockout (UVLO) on input (VDDI), high-side (VDDA), and low-side (VDDB) supplies - each with 5 V turn-on threshold - ensuring safe startup/shutdown sequencing. Outputs default low during UVLO, and DISABLE input forces both outputs low unconditionally when asserted.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8230BD-D-IS | Same SOIC-16 WB package and pinout, but 8 V UVLO and 5 kVRMS isolation | Required where higher isolation (e.g., 600 Vrms working voltage) or wider input supply margin is needed | Select when system requires enhanced safety certification (UL 5000 VRMS) or operates with noisy 8–24 V input rails |
| UCC21520DWR | TI part with 5 kVRMS isolation, 4 A peak output, and integrated Miller clamp; different pinout and enable logic | Used in high-power motor drives requiring >2 A gate drive; not drop-in compatible | Choose only if redesigning for higher current capability and accepting layout changes and new enable sequencing |
Compared with Si8230BD-D-IS, SI8230AB-D-IS offers lower UVLO (5 V) for tighter 5 V logic compatibility but reduced isolation (2.5 kVRMS); versus UCC21520DWR, it provides identical pinout flexibility and lower EMI sensitivity but lacks Miller clamping and higher drive strength.

FAQ
What is the isolation voltage rating of SI8230AB-D-IS?
The SI8230AB-D-IS has a certified 2.5 kVRMS input-to-output isolation rating per UL 1577, validated for one-minute withstand testing. This rating applies to the SOIC-16 wide-body package and supports reinforced insulation in 250–400 Vdc bus applications. It is distinct from the 5 kVRMS variants like SI8230BD-D-IS, which require different safety certifications.
Does SI8230AB-D-IS support programmable dead time?
Yes, SI8230AB-D-IS supports programmable dead time via an external resistor (RDT) connected from the DT pin to ground. The dead time is calculated as DT ≈ 10 × RDT (ns), allowing adjustment from ~400 ps (pin floating) up to several hundred nanoseconds. This feature is integral to its overlap protection function in half-bridge configurations.
What is the UVLO threshold for SI8230AB-D-IS?
The SI8230AB-D-IS has a 5 V undervoltage lockout (UVLO) threshold on all three supply domains: VDDI (input side), VDDA (high-side output), and VDDB (low-side output). Each domain monitors its own supply independently, and outputs remain low until all enabled supplies exceed 5 V. This ensures predictable startup behavior in 5 V logic systems.
Is SI8230AB-D-IS qualified for automotive applications?
Yes, SI8230AB-D-IS is AEC-Q100 qualified (Grade 1, –40°C to +125°C) and manufactured using automotive-specific process flows. Its automotive-grade counterpart is SI8230AB-AS, which shares identical electrical specs and marking but includes AIAG-compliant PPAP documentation and IMDS/CAMDS material reporting required for Tier-1 automotive supply chains.
Can SI8230AB-D-IS drive both high-side and low-side MOSFETs simultaneously?
Yes, SI8230AB-D-IS is explicitly configured as a high-side/low-side driver with independent VOA (high-side) and VOB (low-side) outputs. Its truth table and built-in overlap protection ensure that both outputs never go high simultaneously, preventing shoot-through. The device supports synchronous PWM control using VIA/VIB inputs or can be used with external dead-time generation.
