Product details
Overview
SI82F89AGC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver in High-Side/Low-Side configuration with disable (DIS) input, 6 kVRMS reinforced isolation, <5 ns channel-to-channel skew, and Selectable Variable Current Drive (SelVCD™) supporting eight sourcing/sinking current levels. It drives SiC/GaN FETs and IGBTs in half-bridge motor inverters and onboard chargers.
For engineers reviewing the SI82F89AGC-IS1R datasheet, SI82F89AGC-IS1R pinout, SI82F89AGC-IS1R application, or SI82F89AGC-IS1R equivalent, this page delivers verified functional identity, validated SOIC-14 pin mapping, confirmed automotive-grade AEC-Q100 qualification, exact UVLO thresholds (12 V), and real-world dead time programmability via external resistor on DT pin.
Technical Context
The SI82F89AGC-IS1R implements differential capacitive isolation using dual silicon dioxide (SiO₂) barriers, enabling 200 kV/μs CMTI and stable timing across –40 to 125 °C. Its PWM input architecture synchronizes both outputs with overlap protection triggered by simultaneous high inputs.
It features integrated Miller clamp activated below VMCTA/B (~1.9 V), programmable dead time (via DT–GND resistor), and independent SPD+/SPD– analog control pins that set sourcing/sinking current as a precision current source-eliminating external gate resistors while maintaining ±10% output current tolerance over temperature and process variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute; enables reinforced insulation per VDE 60747-17 and UL 1577. |
| Channel Skew | <5 ns; ensures precise timing alignment between high-side and low-side gate drive signals. |
| Input Supply Range | 3 V to 20 V; supports direct interface with MCU GPIOs and industrial logic without level-shifting. |
| Gate Supply Range | 5 V to 30 V; accommodates 12 V and 15 V gate drive rails for SiC/GaN FETs and IGBTs. |
| UVLO Threshold | 12 V nominal with hysteresis; prevents erratic switching during power-up/down in automotive 12 V systems. |
| CMTI | >200 kV/μs; rejects fast transients in high-dv/dt motor drive and inverter environments. |
| Operating Temp | –40 °C to +125 °C; qualified for under-hood automotive and industrial ambient conditions. |
| AEC-Q100 Grade | Qualified to Grade 1; meets automotive reliability requirements for powertrain and charging systems. |
Pinout & Package
SI82F89AGC-IS1R uses a wide-body 14-pin SOIC package (WB SOIC-14) with 8.3 mm creepage and clearance, optimized for reinforced insulation in high-voltage motor drives and onboard chargers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input supply | 3–20 V digital domain power; powers internal isolator and logic circuits. |
| GNDI | Logic input ground | Reference for all digital inputs (PWM, DIS, DT, SPD±); must be separated from power grounds. |
| PWM | Single-input control signal | Drives VOA high / VOB low when high; VOA low / VOB high when low-enabling half-bridge complementary operation. |
| DIS | Active-high disable | Forces VOA and VOB low unconditionally; used for fault shutdown in motor control safety chains. |
| DT | Dead time programming | Resistor-to-GND sets dead time (10–110 kΩ → ~10–110 ns); connect to VDDI to disable dead time and overlap protection. |
| SPD+ | Sourcing current control | Analog input setting one of eight turn-on current levels; eliminates need for external gate resistors. |
| SPD− | Sinking current control | Analog input setting one of eight turn-off current levels; enables dynamic Miller clamp activation. |
| VDDA | High-side gate driver supply | 5–30 V supply for VOA output stage; independent of VDDB for asymmetric rail designs. |
| GNDA | High-side gate driver ground | Return path for VOA; must be routed separately from GNDB to avoid cross-talk. |
| VDDB | Low-side gate driver supply | 5–30 V supply for VOB output stage; supports floating or grounded low-side configurations. |
| GNDB | Low-side gate driver ground | Return path for VOB; electrically isolated from GNDA and GNDI. |
| VOA | High-side gate driver output | Current-source output with integrated Miller clamp; connects directly to high-side FET gate. |
| VOB | Low-side gate driver output | Current-source output with integrated Miller clamp; connects directly to low-side FET gate. |
| NC | No connection | Pin 13 is unconnected; must remain floating per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels set via SPD+/SPD− analog pins-replaces gate resistors and enables adaptive switching speed. |
| Integrated Miller Clamp | Engages automatically when VOA/VOB falls below ~1.9 V, clamping Miller-induced gate voltage spikes without external components. |
| Programmable Dead Time | Resistor-programmed delay (10–110 ns) between VOA and VOB transitions prevents shoot-through in half-bridge topologies. |
| Overlap Protection | Hardware-level response forces both outputs low if PWM and DIS are simultaneously asserted-no firmware dependency required. |
| Automotive-Grade Isolation | 6 kVRMS reinforced isolation with 1500 VRMS working voltage and 10 kV bipolar surge rating-certified for 2 MOPP per IEC 60601-1. |
| Robust Input Interface | CMOS-compatible, Schmitt-triggered, deglitch-filtered inputs tolerate >4 kV HBM ESD and operate reliably in noisy motor drive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8239AD-IS1R | Universal configuration with EN input; lacks DIS pin; same SOIC-14 package and 6 kVRMS isolation. | Used where enable-based sequencing is preferred over fault-driven disable; no hardware-level overlap protection on simultaneous inputs. | Select SI8239AD-IS1R only if system design uses active-high enable logic and does not require DIS-triggered fail-safe shutdown. |
| UCC5390SCD | Texas Instruments part with 5.7 kVRMS isolation, 35 V max VDD, and fixed 4 A/6 A sourcing/sinking; no SPD± analog control. | Targeted at cost-sensitive industrial inverters; lacks SelVCD™ flexibility and automotive qualification. | Choose UCC5390SCD only for non-automotive applications where fixed-current drive and lower isolation rating are acceptable. |
Compared with SI82F89AGC-IS1R, SI8239AD-IS1R offers enable-based control but omits DIS-driven fault response, while UCC5390SCD provides higher peak current but sacrifices programmable drive strength, automotive qualification, and Miller clamp integration-making SI82F89AGC-IS1R optimal for safety-critical, adaptive-gate-drive automotive power stages.

FAQ
What is the isolation voltage rating of the SI82F89AGC-IS1R?
The SI82F89AGC-IS1R has a certified 6 kVRMS isolation rating for 1 minute per UL 1577 and VDE 60747-17, with a 1500 VRMS working voltage and 10 kV bipolar surge capability-meeting reinforced insulation requirements for automotive and industrial applications.
Does the SI82F89AGC-IS1R support both high-side and low-side gate driving in a single package?
Yes, the SI82F89AGC-IS1R integrates two isolated gate drivers in a High-Side/Low-Side configuration. VOA drives the high-side switch and VOB drives the low-side switch, with hardware-enforced dead time and overlap protection to prevent shoot-through in half-bridge topologies.
How does the SelVCD™ feature work on the SI82F89AGC-IS1R?
SelVCD™ on the SI82F89AGC-IS1R uses SPD+ and SPD− pins to select one of eight discrete sourcing and sinking current levels via resistor dividers or analog voltage sources. This replaces external gate resistors and enables adaptive switching speed-maintaining ±10% current accuracy over temperature and process variation.
What is the purpose of the DIS pin on the SI82F89AGC-IS1R?
The DIS (Disable) pin on the SI82F89AGC-IS1R is an active-high input that unconditionally forces both VOA and VOB outputs low within tDID, providing hardware-level fault shutdown for motor drives and inverters-critical for ISO 26262 ASIL-B/C safety mechanisms.
Is the SI82F89AGC-IS1R qualified for automotive applications?
Yes, the SI82F89AGC-IS1R is AEC-Q100 Grade 1 qualified and built using automotive-specific manufacturing flows. It supports –40 °C to +125 °C operation, 12 V UVLO, and 2 MOPP isolation per IEC 60601-1-making it suitable for EV traction inverters and onboard chargers.
Can the SI82F89AGC-IS1R operate without external gate resistors?
Yes, the SI82F89AGC-IS1R operates as a precision current source with integrated Miller clamp, eliminating the need for external gate resistors. Adding gate resistance degrades Miller clamp effectiveness and increases switching losses-per datasheet guidance, VOA/VOB must connect directly to the FET gate.
