Product details
Overview
SI82390BB-IS1R 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 at 8 V with status feedback. It is used in solar inverters and motor drives requiring robust noise immunity and fail-safe operation.
For engineers reviewing the SI82390BB-IS1R datasheet, SI82390BB-IS1R pinout, SI82390BB-IS1R application, or SI82390BB-IS1R equivalent, key selection criteria include its SOIC-16 narrow-body package, independent VIA/VIB inputs, programmable dead time (10–200 ns), 30 ns propagation delay, and AEC-Q100-qualified automotive-grade variant availability.
Technical Context
The SI82390BB-IS1R implements RF-based silicon isolation with on/off keying modulation, enabling high CMTI (100 kV/µs) and eliminating startup initialization requirements. Its dual-channel architecture provides independent high-side and low-side drive paths with separate VDDA and VDDB supplies up to 24 V.
It integrates enhanced UVLO monitoring per output channel, active-low EN control, fail-safe default-low outputs during VDDI power-down, and a 1 ms delayed safe startup sequence. The device supports deglitch filtering and operates across –40 °C to +125 °C.
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 systems. |
| Peak Output Current | 4.0 A - sufficient to directly drive high-gate-charge IGBTs and SiC MOSFETs without external buffers. |
| Propagation Delay | 30 ns - ensures precise timing alignment between high-side and low-side switching in hard-switched topologies. |
| UVLO Threshold | 8 V on VDDA/VDDB - prevents erratic switching during brown-out conditions while maintaining tight tolerance (±0.3 V). |
| Dead Time Range | 10–200 ns - programmable via external resistor to prevent shoot-through in half-bridge configurations. |
| Operating Temperature | –40 °C to +125 °C - validated for industrial and automotive under-hood environments without derating. |
| CMTI | 100 kV/µs - rejects fast transient noise common in high-dV/dt motor drives and DC-DC converters. |
Pinout & Package
SI82390BB-IS1R is housed in a RoHS-compliant SOIC-16 narrow-body package (5.3 mm width), rated for 260 °C peak reflow per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Input A logic signal | TTL-compatible high-true control input for Channel A; referenced to GNDI. |
| VIB | Input B logic signal | TTL-compatible high-true control input for Channel B; referenced to GNDI. |
| EN | Enable control | Active-high global shutdown pin; forces both outputs low when deasserted. |
| GNDI | Input-side ground | Reference for VDDI, VIA, VIB, EN, and RDY; galvanically isolated from power side. |
| VDDI | Input-side supply | 2.5 V–5.5 V supply powering input logic and isolation barrier; includes UVLO monitoring. |
| RDY | Ready status output | Open-drain digital flag indicating valid output state after safe startup delay (1 ms typical). |
| VDDA | Driver A supply | 10 V–24 V supply for high-side driver; monitored by independent UVLO circuit. |
| VOA | Output A | 4.0 A capable push-pull output driving external MOSFET/IGBT gate; defaults low on fault. |
| GND1 | Driver A ground | Power-side return for VDDA and VOA; isolated from GNDI and GND2. |
| VDDB | Driver B supply | 10 V–24 V supply for low-side driver; independently monitored for UVLO. |
| VOB | Output B | 4.0 A capable push-pull output; synchronized but independently controlled vs. VOA. |
| GND2 | Driver B ground | Power-side return for VDDB and VOB; isolated from GNDI and GND1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated drivers in one package | Eliminates inter-channel skew and reduces PCB area vs. discrete optocoupler + driver solutions. |
| Enhanced output UVLO with status feedback | 8 V threshold per channel with RDY pin assertion only after both VDDA and VDDB are stable and within spec. |
| Fail-safe default-low outputs | VOA and VOB automatically drive low if VDDI is lost - prevents unintended power device turn-on. |
| Programmable dead time (10–200 ns) | Configured via single external resistor; avoids shoot-through without requiring controller-level timing compensation. |
| 1 ms safe delayed startup | Guarantees monotonic output behavior during power-up - critical for transformer-coupled topologies to avoid flux walk. |
| RF-based silicon isolation | Delivers 100 kV/µs CMTI and stable timing over temperature/age vs. LED degradation in optocouplers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si82390BD-IS | SOIC-16 wide-body package (7.5 mm width); identical electrical specs and pinout except larger footprint. | Preferred where board space allows wider creepage/clearance or legacy layout compatibility is required. | Select Si82390BD-IS when mechanical clearance >5.3 mm is available and JEDEC MO-153 compliance is mandated. |
| Si82390BB-AS1 | Automotive-grade variant with AEC-Q100 qualification, PPAP support, and IMDS/CAMDS documentation. | Required for production in automotive OBC, traction inverter, or BMS modules subject to AIAG requirements. | Choose Si82390BB-AS1 for Tier-1 automotive programs needing full automotive process flow and zero-defect manufacturing evidence. |
Compared with SI82390BB-IS1R, Si82390BD-IS offers greater creepage distance in a wider package but no performance difference, while Si82390BB-AS1 adds automotive qualification rigor without altering electrical behavior - making it suitable for production ramp in vehicle platforms.

FAQ
What is the isolation voltage rating of the SI82390BB-IS1R?
The SI82390BB-IS1R is rated for 5 kVRMS isolation withstand voltage per UL 1577 and IEC62368-1, supporting reinforced insulation in industrial and automotive power systems. This rating is validated for 1 minute at 50/60 Hz and applies across the full operating temperature range of –40 °C to +125 °C.
Does the SI82390BB-IS1R support bootstrap power supply for the driver side?
No - the SI82390BB-IS1R does not support bootstrap power for VDDA or VDDB. Its enhanced UVLO architecture requires independent, regulated 10 V–24 V supplies for each driver channel. Using bootstrap circuits may cause undefined behavior or failure to exit UVLO due to shared supply dependency.
How does the RDY pin function on the SI82390BB-IS1R?
The RDY pin on the SI82390BB-IS1R is an open-drain output that goes high only after both VDDI has exited UVLO and both VDDA and VDDB have stabilized above their 8 V thresholds - confirming safe, valid output capability. It remains low during startup, fault, or power loss.
What is the purpose of the 1 ms delayed startup time in the SI82390BB-IS1R?
The 1 ms delayed startup time in the SI82390BB-IS1R ensures monotonic, glitch-free output behavior during power-up - critical for transformer-coupled topologies to prevent flux imbalance and core saturation. Outputs remain low until all supplies are verified, then follow input states.
Can the SI82390BB-IS1R be used in automotive applications?
Yes - the SI82390BB-IS1R has a qualified automotive-grade counterpart (SI82390BB-AS1) built with full AEC-Q100-compliant flows, PPAP documentation, and IMDS/CAMDS support. While the SI82390BB-IS1R itself is industrial-grade, its design and qualification foundation enable seamless migration to automotive production.
