Product details
Overview
SI82E89AEC-IS1 from Skyworks Solutions is a dual-channel, high-side/low-side isolated gate driver with 6 A peak output drive strength, 6 kVRMS reinforced isolation, and <5 ns channel-to-channel skew. It features CMOS inputs, programmable dead time via external resistor, and integrated UVLO (4 V / 8 V / 12 V / 15 V options) for driving SiC, GaN, IGBT, and MOSFET power switches in half-bridge topologies.
For engineers reviewing the SI82E89AEC-IS1 datasheet, SI82E89AEC-IS1 pinout, SI82E89AEC-IS1 application, or SI82E89AEC-IS1 equivalent, key selection criteria include its High-Side/Low-Side configuration with DISABLE (DIS) input, 200 kV/µs CMTI, 1500 VRMS working voltage, automotive-grade AEC-Q100 qualification, and narrow-body SOIC-16 package with reinforced creepage.
Technical Context
The SI82E89AEC-IS1 implements capacitive silicon-dioxide (SiO₂) isolation with differential RF-modulated OOK signaling, enabling robust noise immunity and precise timing. Its functional block includes independent UVLO monitors per supply rail (VDDI, VDDA, VDDB), thermal shutdown with hysteresis, short-circuit clamping, and active pull-down shutdown clamp on unpowered outputs.
This variant uses a PWM input architecture with dedicated DIS (active-high disable) control and DT pin for resistor-programmable dead time insertion-enabling shoot-through prevention in half-bridge motor drives and inverters. It operates across –40 to +125 °C and supports bipolar/unipolar output voltages up to 30 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577, VDE 60747-17, CSA 62368-1) |
| CMTI | >200 kV/µs - ensures reliable operation in noisy high-dV/dt environments like SiC/GaN switching |
| Output Drive Strength | 6 A peak sourcing/sinking - directly drives high-gate-charge power devices without external buffers |
| Channel Skew | <5 ns - enables precise timing alignment critical for high-frequency half-bridge ZVS/ZCS control |
| Input Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V logic controllers without level-shifting |
| Gate Supply Range | 5–30 V - supports both low-voltage MOSFETs and high-threshold SiC/GaN FETs |
| UVLO Thresholds | Configurable at 4 V / 8 V / 12 V / 15 V - prevents erratic switching during brown-out or startup |

Pinout & Package
Narrow-body 16-pin SOIC (SOIC-16 NB) package with 8.0 mm creepage and reinforced insulation barrier between logic and power sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input power supply | Provides 3–20 V bias for internal digital circuitry and isolator modulator |

| VOB | Low-side gate driver output | 6 A capable voltage-source output; includes shutdown clamp to GNDB when unpowered |
| NC | No connection | Pins 12, 13, and 16 are unused; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive SiO₂ Isolation | Enables 6 kVRMS rating, >200 kV/µs CMTI, and stable timing over temperature/lifetime vs optocouplers |
| Programmable Dead Time | Resistor-adjustable delay (18–200 ns) prevents shoot-through in half-bridge power stages |
| Overlap Protection Logic | Hardware-enforced immediate low-state on both outputs if PWM and DIS simultaneously assert high |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SIL1225CD-IM | Single-channel, 4 A output, 5 kVRMS isolation, no dead time programming | Limited to single-FET or non-overlap-critical topologies; lacks DIS input and overlap protection | Choose only for cost-sensitive, low-power single-switch applications where shoot-through risk is mitigated externally |
| UCC5390SCD | 6 A dual-channel, 5.7 kVRMS, 100 kV/µs CMTI, EN input (not DIS), different pinout | Requires PCB redesign due to non-pin-compatible SOIC-16 layout and absence of DT pin | Select when needing TI ecosystem support or specific EN-active-high logic, but expect layout changes and revalidation |
Compared with SIL1225CD-IM and UCC5390SCD, the SI82E89AEC-IS1 uniquely delivers High-Side/Low-Side configuration with hardware-enforced overlap protection, resistor-programmable dead time, and AEC-Q100 qualification - making it optimal for automotive and high-reliability industrial half-bridge systems where timing integrity and safety certification are mandatory.

FAQ
What is the isolation voltage rating of the SI82E89AEC-IS1?
The SI82E89AEC-IS1 has a certified 6 kVRMS isolation rating for one minute per UL 1577, VDE 60747-17, and CSA 62368-1 standards. Its 1500 VRMS working voltage supports continuous operation in 1000 V-class power systems such as EV onboard chargers and solar inverters. This reinforced insulation barrier is implemented using dual SiO₂ capacitors with differential RF modulation.
Does the SI82E89AEC-IS1 support both high-side and low-side gate driving in a single package?
Yes, the SI82E89AEC-IS1 is configured as a High-Side/Low-Side driver with dedicated VOA (high-side) and VOB (low-side) outputs. It accepts a single PWM input and internally generates complementary, dead-time-controlled outputs - eliminating the need for external logic or timing circuits in half-bridge applications.
How is dead time programmed on the SI82E89AEC-IS1?
Dead time is set by connecting an external resistor (RDT) between the DT pin and GNDI. Values from 10 kΩ to 110 kΩ yield typical delays of 18 ns to 200 ns, calculated per Equation 1 (tDT = 1.73 × RDT + 5.74). Connecting DT to VDDI disables dead time and overlap protection, allowing universal dual-driver operation.
What safety certifications does the SI82E89AEC-IS1 hold?
The SI82E89AEC-IS1 is UL recognized (1577), CSA certified (62368-1 and 60601-1 for 2 MOPP), VDE certified (60747-17), and CQC approved (GB4943.1), all confirming reinforced insulation. These approvals validate its use in medical, industrial, and automotive systems requiring stringent galvanic separation and fault tolerance.
Is the SI82E89AEC-IS1 qualified for automotive applications?
Yes, the SI82E89AEC-IS1 is AEC-Q100 qualified (Grade 1, –40 to +125 °C) and manufactured using automotive-specific process flows. It includes integrated thermal shutdown, UVLO per supply rail, and robust ESD protection (4 kV HBM), meeting reliability and safety requirements for EV powertrain and charging systems.
