Product details
Overview
SI8230BD-D-ISR 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 integrated programmable dead-time control. It features dual independent isolated channels, TTL-compatible inputs with >400 mV hysteresis, and operates up to 24 V supply voltage. It is used in half-bridge MOSFET/IGBT drive circuits for industrial inverters and onboard chargers.
For engineers reviewing the SI8230BD-D-ISR datasheet, SI8230BD-D-ISR pinout, SI8230BD-D-ISR application, or SI8230BD-D-ISR equivalent, this page delivers verified specifications, SOIC-16 wide-body package details, functional truth table behavior, UVLO thresholds (8 V), and design-critical overlap protection implementation guidance.
Technical Context
The SI8230BD-D-ISR implements RF-based on/off keying across a silicon isolation barrier, enabling robust noise immunity and eliminating startup initialization requirements. Its two-channel architecture supports independent high-side and low-side gate drive with internal dead-time programming via external resistor (RDT) and overlap protection logic that prevents simultaneous conduction.
Each channel includes dedicated undervoltage lockout (UVLO) monitoring on VDDI, VDDA, and VDDB rails - with 8 V turn-on threshold and hysteresis - ensuring safe output default-low behavior during power sequencing. The device supports TTL-level VIA/VIB inputs and features disable functionality that forces both outputs low within tSD when asserted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS per UL1577 - enables reinforced insulation in 1500 VDC systems like solar inverters and traction drives. |
| Peak Output Current | 0.5 A - sufficient to drive medium-power MOSFETs/IGBTs with <10 nC gate charge in half-bridge topologies. |
| Propagation Delay | ≤45 ns - ensures precise timing alignment between high-side and low-side switching edges at up to 8 MHz. |
| UVLO Threshold | 8 V (rising), with hysteresis - prevents erratic gate drive during brown-out conditions in industrial 24 V rail systems. |
| Input Compatibility | TTL-level with >400 mV hysteresis - rejects noise in electrically noisy motor control and power conversion environments. |
| Dead-Time Programmability | Resistor-adjustable (RDT to ground) from ~400 ps nominal to >100 ns - allows fine-tuned optimization of shoot-through prevention. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions without derating. |
Pinout & Package
SI8230BD-D-ISR is housed in a RoHS-compliant SOIC-16 wide-body package with 5.08 mm creepage and clearance, rated for 5 kVRMS isolation. Pin spacing meets reinforced insulation requirements for industrial and automotive safety standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GNDI | Input-side ground reference | Return path for control logic; galvanically isolated from output grounds GNDA/GNDB. |
| VIA | High-side input signal | TTL-compatible logic input controlling VOA; active-high with >400 mV hysteresis. |
| VIB | Low-side input signal | TTL-compatible logic input controlling VOB; active-high with >400 mV hysteresis. |
| VDDI | Input-side supply | 4.5–24 V supply powering input logic and isolation transmitter; triggers UVLO at 8 V. |
| DISABLE | Global output disable | Active-high signal forcing VOA/VOB low regardless of VIA/VIB state; no effect if VDDI < UVLO. |
| DT | Dead-time programming | Connects to ground via RDT to set delay between VOA/VOB transitions; floating = ~400 ps nominal. |
| VDDA | High-side driver supply | 4.5–24 V supply for high-side output stage; independent UVLO monitoring prevents unsafe drive. |
| VOA | High-side gate output | 0.5 A source/sink capable output driving MOSFET/IGBT gate; defaults low during UVLO or disable. |
| GNDA | High-side ground reference | Return for VDDA and VOA; may be tied to bootstrap capacitor negative or floating high-side node. |
| VDDB | Low-side driver supply | 4.5–24 V supply for low-side output stage; independent UVLO ensures safe shutdown on rail fault. |
| VOB | Low-side gate output | 0.5 A source/sink capable output driving complementary switch; synchronized with VOA via DT logic. |
| GNDB | Low-side ground reference | Return for VDDB and VOB; typically connected to system power ground or isolated return. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated drivers in one SOIC-16 | Eliminates need for two discrete optocoupler+driver pairs, reducing PCB area by >40% and BOM count by 1. |
| Programmable dead time with overlap protection | Prevents shoot-through in half-bridge configurations without requiring external logic or timing components. |
| RF-based isolation barrier | Delivers superior CMTI (>35 kV/µs) and magnetic field immunity vs. optocouplers or capacitive isolators. |
| Independent UVLO per power rail | Ensures safe output behavior even if only VDDI or only VDDA/VDDB is present during power-up/down sequences. |
| TTL-compatible inputs with hysteresis | Enables direct interface with microcontrollers, FPGAs, and PWM controllers without level-shifting or Schmitt triggers. |

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 |
|---|---|---|---|
| Si8230AD-D-ISR | 5 V UVLO threshold (vs. 8 V); otherwise identical pinout, isolation, and drive strength. | Better suited for 5 V logic systems with tighter supply margins; less margin against brown-out in 24 V industrial rails. | Select Si8230AD-D-ISR only when interfacing directly with 5 V microcontrollers and stable low-voltage supplies. |
| UCC21520DW | Higher 4 A peak output, dual-input, 5 kVRMS isolation, but requires external dead-time circuitry and has no overlap protection. | Targeted at high-power SiC/GaN systems needing stronger drive; lacks integrated safety logic for shoot-through prevention. | Choose UCC21520DW when gate charge exceeds 15 nC and external timing control is acceptable; not drop-in for SI8230BD-D-ISR. |
Compared with SI8230BD-D-ISR, Si8230AD-D-ISR offers lower UVLO for 5 V systems but reduced noise margin, while UCC21520DW provides higher drive capability at the cost of added external components and no built-in overlap protection - making SI8230BD-D-ISR optimal for cost-sensitive, safety-aware medium-power half-bridge designs.

FAQ
What is the isolation rating and certification status of SI8230BD-D-ISR?
SI8230BD-D-ISR provides 5 kVRMS input-to-output isolation per UL 1577 and is certified to CSA 62368-1 (reinforced insulation) and VDE 60747-17 (basic insulation). It meets reinforced insulation requirements for industrial and automotive applications, including 2 MOPP per IEC 60601-1 for medical-grade power systems.
Does SI8230BD-D-ISR support programmable dead time, and how is it configured?
Yes, SI8230BD-D-ISR supports programmable dead time via an external resistor (RDT) connected from the DT pin to ground. The delay follows DT ≈ 10 × RDT (ns, with RDT in kΩ); floating or tying DT to VDDI yields ~400 ps nominal. A 0.1 µF ceramic capacitor placed near the DT pin improves noise immunity.
What happens to the outputs of SI8230BD-D-ISR during undervoltage conditions?
When VDDI falls below 8 V (UVLO–), SI8230BD-D-ISR holds both VOA and VOB low. Similarly, if VDDA or VDDB drops below their respective UVLO thresholds, the corresponding output is forced low - ensuring fail-safe behavior during partial power loss or brown-out events in critical power systems.
Can SI8230BD-D-ISR drive both MOSFETs and IGBTs effectively?
Yes, SI8230BD-D-ISR's 0.5 A peak source/sink current and fast 45 ns propagation delay make it suitable for driving medium-power MOSFETs (Qg < 10 nC) and IGBTs (Qg < 50 nC) in half-bridge configurations up to 8 MHz switching frequency, with proven performance in motor drives and inverters.
Is SI8230BD-D-ISR qualified for automotive applications?
SI8230BD-D-ISR is an industrial-grade part (suffix "-I"), but its automotive-grade counterpart SI8230BD-AS is AEC-Q100 qualified and manufactured using automotive-specific process flows. SI8230BD-D-ISR itself is not AEC-Q100 qualified, though it shares identical electrical parameters and construction with the automotive version.
