Product details
Overview
SI8233BB-C-IS1R from Silicon Laboratories is a high-side/low-side isolated gate driver IC with 4.0 A peak output current, 5 kVRMS input-to-output isolation (wide-body SOIC-16), 60 ns max propagation delay, and programmable dead time. It drives IGBTs and MOSFETs in half-bridge topologies for solar inverters and industrial motor control.
For engineers reviewing the SI8233BB-C-IS1R datasheet, SI8233BB-C-IS1R pinout, SI8233BB-C-IS1R application, or SI8233BB-C-IS1R equivalent, key selection criteria include isolation rating, peak drive strength, overlap protection, UVLO thresholds (4.0 V rising), and SOIC-16 wide-body package compatibility with reinforced insulation requirements per UL1577, VDE 0884-5, and IEC 60950-1.
Technical Context
The SI8233BB-C-IS1R implements RF-based on/off keying across a silicon isolation barrier-enabling robust noise immunity without optical degradation or startup initialization. Its dual-channel architecture supports independent high-side and low-side control with TTL-compatible inputs and >400 mV hysteresis.
It integrates programmable dead time via external resistor (70–900 ns range), overlap protection logic, and undervoltage lockout on both input (VDDIUV+ = 4.0 V) and output supplies (VDDA/VDDB UVLO selectable at 5/8/10/12.5 V). Driver outputs tolerate ±24 V supply and support ground-referenced or floating configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 4.0 A sink/source per channel - directly drives high-gate-charge IGBTs and GaN FETs without external buffers. |
| Isolation Rating | 5 kVRMS (1 min, UL1577) - certified for reinforced insulation in 600 VRMS working voltage systems. |
| Propagation Delay | ≤60 ns (max) - enables >8 MHz switching frequency with tight timing control in high-efficiency converters. |
| Input Hysteresis | 450 mV typical - rejects noise on control lines in electrically noisy motor drive or inverter environments. |

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 |
|---|---|---|---|
| Si8233AD-C-IS1R | Same 4.0 A drive and WBSOIC-16 package, but with 12.5 V VDDA/VDDB UVLO threshold (vs. 10 V for SI8233BB-C-IS1R). | Optimized for 15 V gate supplies where higher UVLO prevents false shutdown during rail droop. | Select when using 15 V driver rails and requiring tighter UVLO margin above 12 V. |
| UCC5390SCDR | 4.5 A peak output, 5 kVRMS isolation, but uses capacitive isolation and lacks programmable dead time. | Requires external dead-time circuitry; suited for cost-sensitive non-safety-critical applications. | Choose if needing higher peak current without dead-time programming, and accepting external timing components. |
Compared with Si8233AD-C-IS1R and UCC5390SCDR, SI8233BB-C-IS1R provides optimal balance of integrated safety features (overlap protection, programmable dead time), 10 V UVLO alignment with common 12 V gate supplies, and full regulatory certification for industrial and renewable energy systems.

FAQ
What is the isolation voltage rating of SI8233BB-C-IS1R?
SI8233BB-C-IS1R is rated for 5 kVRMS input-to-output isolation per UL1577 (1 minute test), verified on the wide-body SOIC-16 package. This corresponds to reinforced insulation per VDE 0884-5 and IEC 60950-1, supporting up to 600 VRMS working voltage in end equipment. The device is production-tested to 6.0 kVRMS for quality assurance.
Does SI8233BB-C-IS1R support programmable dead time?
Yes, SI8233BB-C-IS1R supports hardware-programmable dead time via an external resistor connected to the DT pin. The dead time is adjustable from 70 ns to 900 ns depending on resistor value (6 kΩ to 100 kΩ), enabling precise shoot-through prevention without software intervention or external logic.
What are the UVLO thresholds for SI8233BB-C-IS1R?
SI8233BB-C-IS1R has VDDI UVLO rising threshold of 4.0 V (typical) with 250 mV hysteresis. For VDDA/VDDB, it uses a 10 V UVLO option (rising threshold 9.6–12.2 V), confirmed by part number suffix "BB" per Silicon Labs ordering guide - making it compatible with 12 V gate supply rails while avoiding false shutdown during transient dips.
Can SI8233BB-C-IS1R drive both IGBTs and SiC MOSFETs?
Yes, SI8233BB-C-IS1R delivers 4.0 A peak sink/source current and sub-12 ns rise/fall times (CL = 200 pF), enabling direct drive of medium-power IGBTs and discrete SiC MOSFETs. Its 24 V max VDDA/VDDB and robust CMTI (>45 kV/µs) make it suitable for hard-switched SiC half-bridges in high-frequency converters.
Is SI8233BB-C-IS1R AEC-Q100 qualified?
Yes, SI8233BB-C-IS1R is AEC-Q100 qualified Grade 1 (–40 °C to +125 °C ambient), with full temperature-range validation and stress testing. This qualification covers the entire Si823x family and applies to all package variants including the WBSOIC-16 used in SI8233BB-C-IS1R.
