Product details

Overview

SI8230BD-D-IS from Skyworks Solutions is a high-side/low-side isolated gate driver IC with dual independent 5 kVRMS isolation barriers, 0.5 A peak output current per channel, TTL-compatible inputs with >400 mV hysteresis, and integrated programmable dead time control. It operates up to 24 V supply voltage and supports half-bridge MOSFET/IGBT drive in industrial inverters and motor control systems.

For engineers reviewing the SI8230BD-D-IS datasheet, SI8230BD-D-IS pinout, SI8230BD-D-IS application, or SI8230BD-D-IS equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, confirmed automotive-grade alternatives, and supply-chain support details specific to this SOIC-16 wide-body industrial-grade variant.

Technical Context

The SI8230BD-D-IS implements two independent RF-modulated isolation channels using Skyworks' proprietary silicon isolation barrier, enabling simultaneous high-side and low-side gate drive with up to 5 kVRMS input-to-output withstand voltage and 1500 VDC driver-to-driver differential voltage. Its architecture includes dedicated UVLO monitoring per side (8 V threshold), internal overlap protection, and resistor-programmable dead time (via DT pin) to prevent shoot-through in half-bridge topologies.

It accepts dual independent logic inputs (VIA/VIB), supports TTL-level signaling with hysteresis, and features a dedicated DISABLE pin that forces both outputs low regardless of input state. Output propagation delay is ≤45 ns, and switching frequency capability reaches 8 MHz - confirmed for 0.5 A versions under 24 V operation and 100 pF load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5.0 kVRMS per UL1577 - enables reinforced insulation in industrial power supplies and inverters requiring ≥2 MOPP safety compliance.
Peak Output Current	0.5 A per channel - sufficient to drive medium-power MOSFETs/IGBTs in <1 kW half-bridge stages without external buffers.
Propagation Delay	≤45 ns - ensures precise timing alignment between high-side and low-side gate signals in fast-switching converters.
UVLO Threshold	8 V on VDDI, VDDA, and VDDB - prevents erratic gate behavior during brown-out or soft-start conditions.
Input Compatibility	TTL-level with >400 mV hysteresis - rejects noise in electrically noisy motor drive environments without external Schmitt triggers.
Dead Time Control	Resistor-programmable (DT pin) - allows fine-tuned adjustment of non-overlap interval to match specific FET turn-on/off characteristics.
Operating Temperature	–40 °C to +125 °C - supports deployment in under-hood automotive subsystems and industrial enclosures without derating.

Pinout & Package

SI8230BD-D-IS is housed in a RoHS-compliant SOIC-16 wide-body package (10.3 mm × 7.5 mm, 2.35 mm height) with creepage ≥8.3 mm and clearance ≥8.3 mm, rated for 5 kVRMS isolation.

Pin/Terminal	Circuit Role	Design Meaning
VDDI	Input-side power supply	Provides 4.5–24 V to internal RF transmitter; powers VIA/VIB logic and DISABLE function.
GNDI	Input-side ground reference	Reference for all input signals and internal isolation barrier bias; must be separated from output grounds.
VIA	High-side input signal	TTL-compatible logic input controlling VOA; high-true, >400 mV hysteresis improves noise immunity.
VIB	Low-side input signal	TTL-compatible logic input controlling VOB; independent of VIA, enabling asymmetric PWM or phase-shifted control.
DISABLE	Global output disable	Active-high pin forcing VOA/VOB low unconditionally - critical for fault shutdown in safety-critical systems.
DT	Dead time programming	Connects to ground via resistor (R_DT) to set dead time (DT ≈ 10 × R_DT ns); floating or tied to VDDI yields ~400 ps nominal.
VDDA	High-side output power supply	Supplies 4.5–24 V to high-side driver stage; UVLO monitors independently to prevent partial drive failure.
VOA	High-side gate output	0.5 A source/sink capable output driving MOSFET/IGBT gate; referenced to GNDA, not GNDI.
GNDA	High-side output ground	Return path for VOA; electrically isolated from GNDI and GNDB - enables floating high-side operation.
VDDB	Low-side output power supply	Supplies 4.5–24 V to low-side driver; independent UVLO ensures robustness even if VDDA fails.
VOB	Low-side gate output	0.5 A source/sink output referenced to GNDB; complements VOA in half-bridge configurations.
GNDB	Low-side output ground	Return path for VOB; may be connected to system ground or isolated depending on topology requirements.

Key Features

Feature	Design Value
Dual independent isolation channels	Enables fully isolated high-side and low-side gate drive in single SOIC-16 footprint - eliminates need for two optocouplers or discrete isolators.
Programmable dead time with overlap protection	Prevents shoot-through in half-bridge circuits by enforcing minimum off-time between VOA and VOB transitions, configurable from ~400 ps to >1 µs.
RF-based isolation architecture	Delivers superior CMTI (>35 kV/µs) and magnetic field immunity vs. optocouplers - critical for high-dv/dt motor drives and inverters.
Automotive-grade qualification option	Si8230BD-AS variant is AEC-Q100 qualified with PPAP documentation, IMDS/CAMDS support, and zero-defect manufacturing flow - identical pinout and electrical specs.
Wide supply range & robust UVLO	Operates from 4.5 V to 24 V with independent 8 V UVLO on all three power domains (VDDI/VDDA/VDDB) - ensures fail-safe behavior during rail sag.

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-AS	Identical electrical specs and pinout; AEC-Q100 qualified, manufactured in automotive-specific flow with PPAP/IMDS support.	Required for automotive production programs (e.g., OBC, traction inverter auxiliary stages) needing full automotive documentation and zero-defect traceability.	Select Si8230BD-AS when deploying in vehicle platforms requiring AIAG-compliant PPAP, CAMDS listing, or ISO/TS 16949-aligned supply chain.
UCC5390SCD	TI's 5 kVRMS isolated dual-channel driver with 4 A peak output, higher drive strength but no integrated dead time programming or overlap protection logic.	Better suited for high-current GaN/SiC half-bridges where external dead time control is acceptable; lacks built-in shoot-through prevention.	Choose UCC5390SCD only if >0.5 A drive is needed and external dead time generation (e.g., MCU timer) is already implemented in the system.

Compared with Si8230BD-AS and UCC5390SCD, SI8230BD-D-IS provides optimal balance of integration (on-chip dead time, overlap protection), industrial reliability, and cost efficiency for sub-1 kW half-bridge applications - especially where safety certification and layout simplicity are prioritized over raw current drive.
