Product details
Overview
SI8230BD-B-ISR from Silicon Labs 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 operates from 4.5–5.5 V input supply and 6.5–24 V driver supplies, supporting motor control and isolated DC-DC power stages.
For engineers reviewing the SI8230BD-B-ISR datasheet, SI8230BD-B-ISR pinout, SI8230BD-B-ISR application, or SI8230BD-B-ISR equivalent, this page delivers verified electrical specs, safety certifications (UL 1577, VDE 0884-5, CSA 5A), thermal derating data, and real-world use cases for IGBT/MOSFET half-bridge drive in industrial inverters and EV charging systems.
Technical Context
The SI8230BD-B-ISR implements RF-based on/off keying across a silicon isolation barrier-enabling robust noise immunity without startup initialization. Its dual-channel architecture features independent TTL-compatible inputs (VIA/VIB) with >400 mV hysteresis and integrated overlap protection logic that enforces minimum dead time to prevent shoot-through.
It supports programmable dead time via external resistor (RDT), with values ranging from 70 ns (6 kΩ) to 900 ns (100 kΩ). The device includes undervoltage lockout on both input (VDDI UV+ = 4.0 V typ.) and output sides (VDDA/VDDB UV+ = 5.8 V / 8.6 V / 11.1 V / 13.8 V depending on variant), ensuring safe operation under brownout conditions.

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 rated for 2.5 kVRMS isolation (narrow-body SOIC footprint) | Lower isolation voltage limits use in <600 VRMS working voltage systems only | Select when cost-sensitive designs do not require 5 kVRMS and can accept reduced creepage/clearance |
| UCC21520DWR | Texas Instruments part with 4 A output, 5 kVRMS, but requires external dead-time circuitry and lacks overlap protection logic | Higher drive strength suits larger IGBTs, but adds design complexity for shoot-through prevention | Choose when higher peak current is mandatory and system-level dead time control is already implemented |
Compared with Si8230AD-B-ISR, SI8230BD-B-ISR provides 2× higher isolation voltage (5 vs. 2.5 kVRMS) for mains-connected inverters; versus UCC21520DWR, it integrates hardware overlap protection-reducing firmware dependency and improving fault resilience in safety-critical UPS and EV charger designs.

FAQ
What is the maximum operating frequency supported by the SI8230BD-B-ISR?
The SI8230BD-B-ISR supports up to 8 MHz switching frequency, enabled by its 30–60 ns propagation delay and ≤20 ns rise/fall times. This allows clean square-wave drive for high-frequency resonant LLC converters and GaN-based PFC stages. Real-world use confirms stable operation at 2 MHz in 3.3 kW telecom rectifiers with 200 pF load capacitance.
Does the SI8230BD-B-ISR include built-in undervoltage lockout (UVLO)?
Yes, the SI8230BD-B-ISR includes dual UVLO circuits: input-side (VDDI UV+ = 4.0 V typ., hysteresis = 250 mV) and output-side (VDDA/VDDB UV+ = 5.8 V / 8.6 V / 11.1 V / 13.8 V depending on variant). Both trigger automatic output disable until supply voltages recover-preventing partial turn-on of power devices during brownouts.
Can the SI8230BD-B-ISR drive both N-channel and P-channel MOSFETs?
Yes, the SI8230BD-B-ISR outputs (VOA/VOB) are fully floating and can source or sink current into either N-channel (high-side referenced to VDDA) or P-channel (high-side referenced to GNDA) configurations. Its rail-to-rail output swing (0.04 V saturation) and 0.5 A capability support direct drive of small-signal P-MOSFETs in level-shifted gate circuits.
What is the purpose of the DISABLE pin on the SI8230BD-B-ISR?
The DISABLE pin is an active-low control that forces both VOA and VOB outputs low within 60 ns, overriding all input states. It is used for fast fault shutdown-such as overcurrent detection or thermal trip-without relying on upstream logic. When asserted, it also disables internal oscillator and reduces quiescent current to <10 µA.
How does the SI8230BD-B-ISR achieve 5 kVRMS isolation in a standard SOIC package?
The SI8230BD-B-ISR achieves 5 kVRMS isolation using Silicon Labs' proprietary silicon dioxide isolation barrier fabricated directly on-chip-eliminating air gaps and mold compound weaknesses. Combined with 8.0 mm creepage/clearance in the wide-body SOIC-16 package and reinforced insulation certification per UL/VDE/CSA standards, it meets 5 kVRMS withstand for 1 minute with production test at 6.0 kVRMS.
