Product details
Overview
SI8230AB-B-ISR from Silicon Laboratories is a high-side/low-side isolated gate driver IC with 0.5 A peak output current, 5 kVRMS input-to-output isolation (wide-body SOIC-16), 60 ns max propagation delay, and programmable dead time. It integrates two independent isolated drivers in one package and is used in half-bridge IGBT/MOSFET gate drive circuits for solar inverters and motor control systems.
For engineers reviewing the SI8230AB-B-ISR datasheet, SI8230AB-B-ISR pinout, SI8230AB-B-ISR application, or SI8230AB-B-ISR equivalent, this page delivers verified technical context, exact pin functions, real-world use scenarios, and validated alternative parts - all aligned to the official Si823x Rev. 1.5 specification and ordering guide.
Technical Context
The SI8230AB-B-ISR implements RF-based on/off keying across a silicon isolation barrier, enabling robust noise immunity without startup initialization. Its dual-channel architecture supports independent high-side and low-side control with overlap protection and externally programmable dead time via resistor (RDT).
It features TTL-compatible inputs with 400 mV hysteresis, operates from 4.5–5.5 V on the input side and 6.5–24 V on each driver side, and maintains stable operation from –40 °C to +125 °C. Common-mode transient immunity exceeds 45 kV/µs at 1500 VCM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS (1 min, UL 1577); certified for reinforced insulation per IEC 60950-1, IEC 60601-1, and VDE 0884-5. |
| Peak Output Current | 0.5 A sink / 0.25 A source per channel - sufficient for driving medium-power IGBTs and MOSFETs in <1 kW inverters. |
| Propagation Delay | ≤60 ns (max) with ≤5.6 ns pulse-width distortion - enables precise timing control up to 8 MHz switching frequency. |
| Input Hysteresis | 400 mV - ensures noise-immune logic-level signal reception in electrically noisy motor drive environments. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1, suitable for under-hood automotive and industrial ambient conditions. |
| Supply Voltage Range | VDDI: 4.5–5.5 V; VDDA/VDDB: 6.5–24 V - supports standard 5 V logic and 12/15/24 V gate drive rails without level-shifting. |
| Common-Mode Immunity | ≥45 kV/µs - prevents false triggering during fast voltage transients in high-dv/dt power stages. |
Pinout & Package
SI8230AB-B-ISR uses a 16-pin wide-body SOIC (WBSOIC-16) package with 8.0 mm creepage/clearance, rated for 5 kVRMS isolation. Pin numbering follows standard SOIC convention (pin 1 = top-left corner, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Input-side terminals (GNDI, VDDI, VIA, VIB, DISABLE) | Isolated input domain: powers logic interface and accepts independent HS/LS control signals with hysteresis. |
| 9, 10, 11, 12, 13, 14, 15, 16 | Output-side terminals (GNDA, VDDA, VOA, GNDB, VDDB, VOB) | Isolated driver domain: supplies dual gate-drive outputs referenced to separate high-side and low-side grounds. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable dead time | Adjustable from ~70 ns to 900 ns via external RDT resistor - eliminates shoot-through in half-bridge topologies without MCU intervention. |
| Overlap protection | Hardware-enforced blanking during simultaneous HS/LS high states - prevents destructive cross-conduction regardless of input timing errors. |
| RF isolation architecture | Silicon Labs' proprietary RF modulation replaces optocouplers - delivers 60 ns propagation vs. >100 ns typical for opto-isolators, with no LED aging or CMTI degradation. |
| AEC-Q100 qualification | Grade 1 (–40 °C to +125 °C) - validated for automotive powertrain and charging applications requiring long-term reliability. |
| Thermal derating support | θJA = 100 °C/W (WBSOIC-16); safety-limiting current remains ≥50 mA up to 150 °C case temperature per DIN EN 60747-5-5. |

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-B-ISR | Same 0.5 A output and WBSOIC-16 package, but with 12.5 V VDDA/VDDB UVLO threshold (vs. 5 V for SI8230AB-B-ISR). | Requires 15 V driver supply (not 12 V); suited for higher-bus-voltage systems where tighter UVLO margin is needed. | Select when system VDDA/VDDB rail is 15 V and UVLO must trigger above 12.4 V to avoid false shutdown during ripple. |
| UCC21520DW | Texas Instruments part with 4 A output, dual-channel, 5 kVRMS isolation, but uses different pinout and lacks programmable dead time. | Higher drive strength supports larger IGBTs; requires external dead-time circuitry or MCU timing control. | Choose when >0.5 A peak current is required and board layout allows rework for non-pin-compatible footprint. |
Compared with SI8230AB-B-ISR, Si8230AD-B-ISR offers higher UVLO threshold for 15 V gate supplies, while UCC21520DW provides greater drive strength but removes integrated dead-time programming - making SI8230AB-B-ISR optimal for cost-sensitive, space-constrained 12 V gate-drive designs needing hardware-enforced timing safety.

Does the SI8230AB-B-ISR support programmable dead time?
Yes, the SI8230AB-B-ISR supports hardware-programmable dead time via an external resistor (RDT) connected between the DT pin and VDDI. With RDT values from 6 kΩ to 220 kΩ, dead time is adjustable from approximately 70 ns to 900 ns - enabling precise shoot-through prevention without firmware dependency.
What is the maximum switching frequency supported by the SI8230AB-B-ISR?
The SI8230AB-B-ISR supports up to 8 MHz switching frequency, enabled by its 60 ns maximum propagation delay, ≤5.6 ns pulse-width distortion, and 12 ns typical rise/fall times (CL = 200 pF). This makes it suitable for high-frequency resonant converters and Class D audio amplifiers requiring tight timing control.
