Product details
Overview
SI82392BB-AS1R 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 integrated safety features including enhanced UVLO detection, EN pin control, and fail-safe low-default outputs during VDDI power-down. It drives power MOSFETs and IGBTs in motor control inverters and isolated DC-DC converters.
For engineers reviewing the SI82392BB-AS1R datasheet, SI82392BB-AS1R pinout, SI82392BB-AS1R application, or SI82392BB-AS1R equivalent, key selection criteria include its 8 V output UVLO threshold, SOIC-16 narrow-body package, programmable dead time capability, 30 ns propagation delay, and automotive-grade AEC-Q100 qualification for traction inverter and on-board charger designs.
Technical Context
The SI82392BB-AS1R implements RF-based silicon isolation with a 5 kVRMS withstand voltage and 100 kV/µs CMTI, enabling robust noise immunity in high dv/dt environments. Its high-side/low-side topology uses separate VIA and VIB inputs to independently control each output channel.
It features output UVLO monitoring per driver side (VDDA/VDDB), status feedback via RDY pin, and failsafe behavior: both outputs drive low when VDDI is unpowered or when either driver supply falls below its UVLO threshold. Startup includes a safe 1 ms delayed initialization sequence.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 4.0 A - sufficient to directly drive high-gate-charge IGBTs and SiC MOSFETs without external buffers. |
| Input Supply Range (VDDI) | 2.5 V–5.5 V - compatible with modern low-voltage microcontrollers and logic families. |
| Output UVLO Threshold | 8 V - ensures reliable turn-off of power devices before driver supply collapse in fault conditions. |
| Propagation Delay | 30 ns - enables precise timing control in high-frequency switching applications up to 1 MHz. |
| Isolation Withstand Voltage | 5 kVRMS - meets reinforced insulation requirements per IEC62368-1 and UL 1577. |
| Operating Temperature | –40 °C to +125 °C - supports under-hood automotive and industrial ambient conditions. |
| AEC-Q100 Grade | Qualified - certified for automotive applications including traction inverters and battery management systems. |
Pinout & Package
SI82392BB-AS1R is housed in a RoHS-compliant SOIC-16 narrow-body package (5.3 mm width), optimized for high-density PCB layouts in space-constrained power modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | High-side input | TTL-compatible logic input controlling VOA; high-true signal drives VOA high. |
| VIB | Low-side input | TTL-compatible logic input controlling VOB; high-true signal drives VOB high. |
| EN | Enable control | Active-high pin that forces both outputs low when deasserted; requires 100 kΩ pull-down to GNDI. |
| RDY | Status feedback | Open-drain output indicating valid operation after startup delay; pulled high externally to indicate readiness. |
| VDDI | Input-side supply | 2.5–5.5 V supply powering input logic and isolation transmitter; UVLO triggers at 2.3 V (typ). |
| VDDA | High-side driver supply | 10–24 V supply for high-side output stage; monitored for 8 V UVLO (Si82392BB variant). |
| VDDB | Low-side driver supply | 10–24 V supply for low-side output stage; independently monitored for 8 V UVLO. |
| VOA | High-side output | 4.0 A peak source/sink driver output; defaults low during VDDI power-down or VDDA UVLO. |
| VOB | Low-side output | 4.0 A peak source/sink driver output; defaults low during VDDI power-down or VDDB UVLO. |
| GNDI | Input-side ground | Reference for input logic and isolation barrier; galvanically isolated from power-side grounds. |
| GND1/GND2 | Driver-side grounds | Separate grounds for high-side and low-side driver stages; enable independent return paths. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced output UVLO with status feedback | Independent 8 V UVLO monitoring on VDDA and VDDB, with fault indication via RDY pin for system-level diagnostics. |
| Fail-safe default-low outputs | Both VOA and VOB actively drive low when VDDI is absent or either driver supply drops below UVLO - prevents shoot-through in half-bridge configurations. |
| Safe delayed startup | 1 ms monotonic startup delay ensures stable power sequencing before output activation, eliminating transient glitches during power-up. |
| Programmable dead time | Configurable 10–200 ns dead time (via external resistor) prevents simultaneous conduction in complementary switching topologies. |
| High CMTI immunity | 100 kV/µs common-mode transient immunity maintains signal integrity in noisy motor drive and inverter environments. |

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 |
|---|---|---|---|
| SI82332BD-AS1R | SOIC-16 wide-body package; same 4 A drive, 8 V UVLO, but no RDY pin or programmable dead time. | Lacks status feedback and dead-time tuning - suitable for cost-sensitive non-diagnostic applications. | Choose when board layout allows wider SOIC and diagnostic features are unnecessary. |
| UCC5390SCDR | Texas Instruments part; 4 A drive, 5 kVRMS isolation, but only 3.3–5.5 V VDDI range and no enhanced UVLO status reporting. | No dedicated UVLO status pin or fail-safe low-default on VDDI loss - requires external supervision circuitry. | Select if TI ecosystem integration is prioritized and external fault monitoring is already implemented. |
Compared with SI82332BD-AS1R and UCC5390SCDR, SI82392BB-AS1R uniquely combines RDY status feedback, programmable dead time, and fail-safe low-default behavior on VDDI loss - critical for functional safety in automotive traction and OBC systems where autonomous fault response is required.

FAQ
What is the input voltage range for the SI82392BB-AS1R VDDI supply?
The SI82392BB-AS1R supports an input-side supply voltage (VDDI) range of 2.5 V to 5.5 V. This allows direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting. The device enters undervoltage lockout (UVLO) when VDDI falls below approximately 2.3 V (typical), and resumes normal operation once VDDI rises above 2.5 V. This range is confirmed in the Electrical Characteristics table of the official Si8239x datasheet.
Does the SI82392BB-AS1R provide status feedback for UVLO faults?
Yes, the SI82392BB-AS1R provides UVLO status feedback via the RDY pin - an open-drain output that goes high only after successful startup and while both VDDA and VDDB remain above their 8 V UVLO thresholds. If either driver supply drops below UVLO, RDY is pulled low, enabling real-time fault detection in systems like traction inverters. This behavior is explicitly defined in Table 2.2 (Si82392/5/6 Drivers with UVLO Status) of the datasheet.
What is the maximum isolation voltage rating for the SI82392BB-AS1R?
The SI82392BB-AS1R is rated for 5 kVRMS isolation withstand voltage per UL 1577 and VDE 0884-10 (basic insulation), with reinforced insulation compliance to IEC62368-1 and EN60950-1. This rating applies across the full temperature range and lifetime of the device, validated through accelerated life testing. The isolation barrier uses Skyworks' proprietary silicon RF technology - not optocouplers - enabling higher CMTI (100 kV/µs) and longer service life.
Is the SI82392BB-AS1R pin-compatible with other Si8239x variants?
No, the SI82392BB-AS1R is not universally pin-compatible across all Si8239x variants. While it shares the SOIC-16 narrow-body footprint with Si82390/1/5/6BB-IS1/AS1 parts, pin functions differ - notably, Si82392BB lacks the UVLO status pin (present in Si82390/1/3) and has distinct truth table behavior per Table 2.2. Always verify pin mapping against the specific variant's datasheet section "6. Pin Descriptions" before substitution.
What safety certifications does the SI82392BB-AS1R hold?
The SI82392BB-AS1R holds AEC-Q100 Grade 1 qualification for automotive use and is pending UL 1577, CSA, VDE 0884-10, IEC60950-1, IEC62368-1, and GB4943.1-2011 certifications. These cover reinforced insulation requirements for high-voltage isolation barriers. Certification documentation is available through Skyworks' Automotive Support Portal for qualified customers, and PPAP packages are provided for AIAG-compliant production releases.
