Product details
Overview
SI82392BB-IS1 from Skyworks Solutions is a high-side/low-side isolated gate driver IC with dual 4.0 A peak output, 2.5 V–5.5 V input supply (VDDI), and enhanced UVLO safety without status pin. It features 5 kVRMS isolation, 100 kV/µs CMTI, and operates across –40 °C to +125 °C for motor control inverters and isolated DC-DC power supplies.
For engineers reviewing the SI82392BB-IS1 datasheet, SI82392BB-IS1 pinout, SI82392BB-IS1 application, or SI82392BB-IS1 equivalent, key selection considerations include its non-status-enhanced UVLO behavior, SOIC-16 narrow-body package, independent VIA/VIB inputs, and absence of programmable dead time or deglitch filtering - distinguishing it from PWM-input or status-pin variants in the Si8239x family.
Technical Context
The SI82392BB-IS1 implements two independent isolated channels using Skyworks' RF-based silicon isolation barrier, supporting high-side/low-side MOSFET/IGBT drive with fail-safe low-default outputs during VDDI power-down. Its logic operation follows truth table 2.2 (Si82392/5/6 drivers), where VOA and VOB respond directly to VIA and VIB when EN is high and both VDDA and VDDB are valid.
Unlike Si82390/1/3 variants, SI82392BB-IS1 does not feed UVLO fault status back across the isolation barrier; instead, each output independently enters UVLO if its respective driver supply (VDDA or VDDB) falls below threshold. It lacks delayed startup (tSTARTUP_SAFE = N/A) and programmable dead time, confirming its role as a basic high-side/low-side driver without timing coordination features.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS withstand voltage - enables reinforced insulation per IEC62368-1 and UL 1577 for safety-critical power stage separation. |
| Peak Output Current | 4.0 A - drives high-gate-charge MOSFETs/IGBTs directly without external buffers in motor inverter half-bridges. |
| VDDI Range | 2.5 V–5.5 V - interfaces directly with low-voltage microcontrollers (e.g., 3.3 V or 5 V logic) without level-shifting. |
| CMTI | 100 kV/µs - rejects fast common-mode transients in noisy power converter environments, preventing false triggering. |
| Operating Temperature | –40 °C to +125 °C - supports industrial and automotive under-hood applications without derating. |
| UVLO Threshold | 8 V (VDDA/VDDB) - ensures stable gate drive only when driver supplies meet minimum regulation, preventing weak turn-on. |
| Package | SOIC-16 narrow body - provides 8.0 mm creepage/clearance and fits standard PCB footprints for space-constrained inverters. |
Pinout & Package
SI82392BB-IS1 is housed in a RoHS-compliant SOIC-16 narrow-body package (7.5 mm width), rated for 260 °C peak reflow, with 0.050" lead pitch and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Input A | TTL-compatible high-true logic input controlling high-side output VOA. |
| VIB | Input B | TTL-compatible high-true logic input controlling low-side output VOB. |
| EN | Enable (active high) | Pulls both outputs low when driven low; requires external 100 kΩ pull-down to GNDI. |
| VDDI | Input-side supply | 2.5 V–5.5 V power for isolation barrier and input logic; unpowered → outputs default low. |
| GNDI | Input-side ground | Reference for VIA, VIB, EN, and VDDI; galvanically isolated from driver-side grounds. |
| VDDA | Driver A supply | 10 V–24 V supply for high-side output stage; triggers UVLO if <8 V. |
| VOA | Output A | 4.0 A peak high-side gate driver output; actively driven low on VDDA UVLO or EN low. |
| GND1 | Driver A ground | Return path for VDDA and VOA; isolated from GNDI and GND2. |
| VDDB | Driver B supply | 10 V–24 V supply for low-side output stage; triggers UVLO if <8 V. |
| VOB | Output B | 4.0 A peak low-side gate driver output; actively driven low on VDDB UVLO or EN low. |
| GND2 | Driver B ground | Return path for VDDB and VOB; isolated from GNDI and GND1. |
| NC | No connect | Pins 1, 15, 16 - internally unused; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe low-default outputs | VOA and VOB drive low when VDDI is absent - prevents unintended power device turn-on during brownout or startup. |
| Independent driver UVLO | VDDA and VDDB each monitored separately; VOA/VOB disabled only when their own supply fails - avoids single-point failure shutdown. |
| High CMTI (100 kV/µs) | Rejects fast dv/dt noise across isolation barrier in high-power switching nodes - critical for reliable operation in SiC/GaN inverters. |
| 4.0 A peak sink/source | Directly drives gates of 100 A+ IGBTs or high-Qg MOSFETs without external buffers - reduces BOM count and layout complexity. |
| SOIC-16 narrow-body footprint | Standard 7.5 mm width package compatible with automated assembly and existing thermal pad layouts - no redesign needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI82391BB-IS1 | Same SOIC-16 NB package and 8 V UVLO, but includes UVLO status feedback pin (RDY) and enhanced UVLO behavior. | Enables controller-level fault detection and coordinated shutdown - required where system diagnostics are mandated. | Select SI82391BB-IS1 if RDY pin reporting and cross-channel UVLO coordination are needed; SI82392BB-IS1 is preferred for cost-sensitive, status-free implementations. |
| UCC5390SCDR | Texas Instruments part with 4 A output, 5 kVRMS isolation, but uses capacitive isolation and has fixed 3.3/5 V VDDI (no 2.5 V support). | Lacks 2.5 V logic compatibility and independent UVLO per channel - less flexible for ultra-low-voltage MCU interfacing. | Choose UCC5390SCDR only if TI ecosystem alignment or capacitive-isolation preference outweighs VDDI flexibility and UVLO granularity. |
Compared with SI82391BB-IS1, SI82392BB-IS1 omits the RDY status pin and inter-channel UVLO feedback, simplifying control but removing diagnostic capability; versus UCC5390SCDR, it offers broader VDDI range and finer per-rail UVLO monitoring, enhancing robustness in mixed-supply systems.

FAQ
What is the UVLO behavior of the SI82392BB-IS1?
The SI82392BB-IS1 implements independent undervoltage lockout on VDDA and VDDB, each with an 8 V threshold. If either supply drops below 8 V, its corresponding output (VOA or VOB) is forced low. Unlike Si82390/1/3 variants, SI82392BB-IS1 does not feed UVLO status back across the isolation barrier - there is no RDY pin or inter-channel coordination. This behavior is confirmed in Table 2.2 of the datasheet.
Does the SI82392BB-IS1 support programmable dead time?
No, the SI82392BB-IS1 does not support programmable dead time. Dead-time programming is only available on Si82394/8 series parts (e.g., SI82394BB4-IS1) with PWM input architecture. SI82392BB-IS1 uses independent VIA/VIB inputs and relies on external timing control or MCU-level dead-time insertion. This is explicitly stated in the Ordering Guide and confirmed by the absence of dead-time setting fields for this OPN.
What package type is used for the SI82392BB-IS1?
The SI82392BB-IS1 uses a SOIC-16 narrow-body package (7.5 mm width), as specified in Table 1.1 of the Si8239x Data Sheet under "Package Type" for this ordering part number. It is RoHS-compliant, qualified for 260 °C peak reflow, and features 0.050" lead pitch - distinct from wide-body (10.3 mm) or SOIC-14 variants in the same family.
Is the SI82392BB-IS1 automotive-qualified?
Yes, the SI82392BB-IS1 has an automotive-grade counterpart: SI82392BB-AS1. The industrial-grade SI82392BB-IS1 shares identical electrical parameters and construction with its automotive version but is manufactured using industrial process flows. Automotive qualification (AEC-Q100) applies only to the -AS1 suffix variant, which includes AIAG-compliant PPAP documentation and IMDS/CAMDS support.
What is the maximum recommended switching frequency for the SI82392BB-IS1?
The SI82392BB-IS1 does not specify a hard maximum switching frequency. Its 30 ns propagation delay and 100 kV/µs CMTI support operation up to 500 kHz in typical gate-drive applications. Practical limits depend on external gate resistor (RG), FET gate charge (QG), and driver supply voltage (VDDA/VDDB); the datasheet's power dissipation model (Equation 1) shows usable frequency ranges up to 350 kHz for common 24 nC FETs with 22 Ω RG at 12 V.
