Product details
Overview
SI82390BD-IS3 from Skyworks Solutions is a dual-channel isolated gate driver IC designed for high-side/low-side MOSFET and IGBT control in power converters. It delivers 4.0 A peak output current, operates with 2.5 V–5.5 V input supply (VDDI), supports up to 5 kVRMS isolation, and features enhanced output UVLO with status feedback and 1 ms safe delayed startup. It is used in solar inverters, motor drives, and isolated DC-DC supplies.
For engineers reviewing the SI82390BD-IS3 datasheet, SI82390BD-IS3 pinout, SI82390BD-IS3 application, or SI82390BD-IS3 equivalent, key selection criteria include its SOIC-14 wide-body package, independent VIA/VIB inputs, 8 V output UVLO threshold, programmable dead time (10–200 ns), and fail-safe low-default outputs during VDDI power-down.
Technical Context
The SI82390BD-IS3 implements RF-based silicon isolation with on/off keying modulation across a reinforced insulation barrier, enabling high CMTI (100 kV/µs) and eliminating optocoupler aging limitations. Its dual-channel architecture supports independent high-side/low-side drive with separate input pins (VIA, VIB) and dedicated driver supplies (VDDA, VDDB).
It integrates enhanced UVLO monitoring per output channel, status feedback via RDY pin, active-high EN enable with internal pull-down requirement, and deglitch filtering. Startup behavior includes a monotonic 1 ms delay before valid output transitions, ensuring safe initialization in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS withstand voltage - meets reinforced insulation requirements per IEC 62368-1 and UL 1577. |
| Peak Output Current | 4.0 A - sufficient to rapidly charge/discharge high-Qg power devices (e.g., 1200 V SiC MOSFETs) without external buffers. |
| Input Supply Range (VDDI) | 2.5 V to 5.5 V - enables direct interfacing with 3.3 V or 5 V controllers without level-shifting. |
| Output UVLO Threshold | 8 V - ensures reliable turn-off of power switches when driver supply drops below safe conduction margin. |
| Propagation Delay | 30 ns - enables precise timing control in high-frequency (>100 kHz) switching applications. |
| Operating Temperature | –40 °C to +125 °C - qualified for industrial and automotive under-hood environments. |
| Dead Time Programmability | 10–200 ns - prevents shoot-through in half-bridge configurations without external RC networks. |
Pinout & Package
SI82390BD-IS3 is housed in a RoHS-compliant SOIC-14 wide-body package (7.5 mm body width, 10.3 mm length) with creepage/clearance optimized for reinforced isolation. Pin spacing complies with IPC-7351B standard for 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Channel A input | TTL-compatible high-true logic input controlling VOA; referenced to GNDI. |
| VIB | Channel B input | TTL-compatible high-true logic input controlling VOB; referenced to GNDI. |
| EN | Enable control | Active-high enable; must be pulled down to GNDI via 100 kΩ resistor when unused to prevent unintended operation. |
| VDDI | Input-side supply | 2.5–5.5 V supply powering input logic and isolation transmitter; decoupled with 1 µF + 0.1 µF capacitors. |
| GNDI | Input-side ground | Reference for VIA, VIB, EN, VDDI; galvanically isolated from power-side grounds. |
| VOA | Channel A output | 4.0 A capable high-side/low-side driver output; defaults low during VDDI UVLO or EN deactivation. |
| VOB | Channel B output | 4.0 A capable high-side/low-side driver output; independently monitored for UVLO and fault feedback. |
| VDDA | Driver A supply | 10–24 V supply for VOA output stage; requires local 10 µF + 0.1 µF decoupling. |
| VDDB | Driver B supply | 10–24 V supply for VOB output stage; independent of VDDA to support asymmetric topologies. |
| GND1 | Driver A ground | Power ground for VOA; isolated from GNDI and GND2. |
| GND2 | Driver B ground | Power ground for VOB; isolated from GNDI and GND1. |
| RDY | Ready status | Open-drain digital output indicating valid VDDI and absence of UVLO faults; pulled up externally to VDDI. |
| NC | No connect | Internally unconnected pin; left floating per datasheet recommendation. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced output UVLO with feedback | Detects VDDA/VDDB undervoltage and forces corresponding output low while asserting RDY low - prevents partial switching in multi-rail systems. |
| Fail-safe default-low outputs | VOA and VOB drive low when VDDI is unpowered or in UVLO - eliminates floating gate states that could cause shoot-through or latch-up. |
| Programmable dead time (10–200 ns) | Configurable via external resistor to eliminate need for discrete delay circuits in half-bridge gate drive layouts. |
| 1 ms safe delayed startup | Guarantees monotonic output behavior after VDDI stabilization - simplifies system-level power sequencing and avoids transient glitches. |
| RF-based silicon isolation | Delivers 100 kV/µs CMTI and stable performance over temperature/age vs. optocouplers - no LED degradation or parameter drift. |
Applications
| Solar Inverter Half-Bridge | Industrial Motor Drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8233BD-IS3 | Single-channel, 4 A output, same SOIC-14 WB package but lacks UVLO status feedback and RDY pin. | Suitable for simpler half-bridge designs where only one channel requires isolation; no cross-channel UVLO coordination. | Select when cost-sensitive single-output isolation suffices and enhanced fault reporting is not required. |
| UCC5390SCD | TI device with 5 A peak drive, integrated Miller clamp, but only 3.75 kVRMS isolation and no programmable dead time. | Better suited for high-reliability SiC gate drive with Miller clamping, but requires external dead-time generation. | Choose when Miller clamping is critical and lower isolation rating is acceptable; verify CMTI (100 kV/µs) match is maintained. |
Compared with SI82390BD-IS3, SI8233BD-IS3 reduces integration by omitting status feedback and dual-channel coordination, while UCC5390SCD trades isolation robustness and dead-time flexibility for higher peak current and built-in clamping - making SI82390BD-IS3 optimal for safety-critical, dual-channel, transformer-balanced topologies.

FAQ
What is the isolation voltage rating of the SI82390BD-IS3?
The SI82390BD-IS3 provides 5 kVRMS isolation rating per UL 1577 and IEC 62368-1 standards, certified for reinforced insulation. This rating applies across the full operating temperature range (–40 °C to +125 °C) and is validated for 1 minute at rated voltage. The isolation barrier uses Skyworks' proprietary silicon-dielectric technology, not optocoupler-based construction.
Does the SI82390BD-IS3 support bootstrap power supply configurations?
No - the SI82390BD-IS3 must not be used with bootstrap power supplies for VDDA or VDDB. Its enhanced UVLO architecture requires independent, regulated supplies for each driver channel to ensure accurate fault detection and cross-channel feedback. Bootstrap configurations violate the independent supply requirement and may cause undefined output behavior or failure to enter UVLO shutdown.
What is the function of the RDY pin on the SI82390BD-IS3?
The RDY pin on the SI82390BD-IS3 is an open-drain status indicator that goes low when VDDI is invalid or either VDDA or VDDB enters UVLO. It remains high only when all three supplies are within specification and no UVLO faults are active. External pull-up to VDDI is required; it enables system-level fault monitoring without additional sensing circuitry.
Can the SI82390BD-IS3 drive both high-side and low-side switches simultaneously?
Yes - the SI82390BD-IS3 is configured as a high-side/low-side driver with independent VIA and VIB inputs, allowing simultaneous and asynchronous control of two switches. Its 10–200 ns programmable dead time prevents shoot-through, and its 4.0 A peak output current supports direct drive of power devices up to 1200 V SiC MOSFETs without external buffers.
Is the SI82390BD-IS3 qualified for automotive applications?
The SI82390BD-IS3 is an industrial-grade part (suffix "-IS3"). An automotive-grade variant - SI82390BD-AS3 - is available and qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C), with AIAG-compliant PPAP documentation, IMDS/CAMDS compliance, and zero-defect manufacturing flow. SI82390BD-IS3 itself is not AEC-Q100 qualified.
