Product details
Overview
SI82E99ACE-IS3R from Skyworks Solutions is a dual-channel isolated gate driver with high-side/low-side configuration, 6 A peak output current per channel, <5 ns channel-to-channel skew, and 6 kVRMS reinforced isolation. It drives SiC/GaN MOSFETs and IGBTs in half-bridge topologies for onboard chargers and motor inverters.
For engineers reviewing the SI82E99ACE-IS3R datasheet, SI82E99ACE-IS3R pinout, SI82E99ACE-IS3R application, or SI82E99ACE-IS3R equivalent, key selection criteria include its PWM-input architecture, programmable dead time via external resistor, UVLO thresholds (4/8/12/15 V options), CMTI >200 kV/µs, and AEC-Q100 qualification for automotive power systems.
Technical Context
The SI82E99ACE-IS3R implements a PWM-input, high-side/low-side gate driver architecture using capacitive silicon dioxide isolation with RF-modulated OOK signaling. Its functional block includes independent UVLO monitors per supply rail (VDDI, VDDA, VDDB), integrated dead time control logic tied to the DT pin, and shutdown clamps active during unpowered conditions.
It supports universal timing behavior: propagation delay <60 ns (typ), pulse width distortion <5 ns, and operates across –40 to +125 °C with 3–20 V input supply and 5–30 V gate drive supply. The device enforces overlap protection by forcing both outputs low on simultaneous high inputs, preventing shoot-through in half-bridge circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute - meets UL 1577, VDE 60747-17, and CSA 62368-1 reinforced insulation requirements. |
| Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate drive signals in half-bridge operation. |
| CMTI | >200 kV/µs - rejects fast common-mode transients in high-dv/dt power converter environments. |
| Output Drive | 6 A peak sourcing/sinking - directly drives high-capacitance wide-bandgap FET gates without external buffers. |
| UVLO Thresholds | Configurable at 4 V, 8 V, 12 V, or 15 V - prevents erroneous switching during brown-out or startup under marginal supply conditions. |
| Dead Time Control | Resistor-programmable (10–110 kΩ) - sets precise inter-channel delay (tDT = 1.73 × RDT + 5.74 ns) to avoid shoot-through. |
| Operating Temp | –40 to +125 °C - supports under-hood automotive and industrial power module applications. |
Pinout & Package
Narrow-body 16-pin SOIC (SOIC-16 NB) package with creepage/clearance optimized for reinforced isolation. Pinout matches Figure 4 (Si82E99x) in Skyworks datasheet 206857C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input power supply | 3–20 V digital supply; powers internal isolator and input logic; triggers UVLO if below selected threshold. |
| GNDI | Logic input ground | Reference for all digital inputs; must be separated from power grounds to maintain isolation barrier integrity. |
| PWM | Single logic input for both channels | Drives VOA high / VOB low when high; VOA low / VOB high when low - enables complementary half-bridge control with one signal. |
| EN | Active-high enable | Asserting EN = high enables normal operation; deasserting EN = low forces VOA and VOB low unconditionally. |
| DT | Dead time programming input | Connect external resistor to GNDI to set dead time; connect to VDDI to disable dead time and overlap protection. |
| VDDA | High-side gate driver supply | 5–30 V supply for channel A; independent UVLO monitoring prevents false turn-on during undervoltage. |
| GNDA | High-side gate driver ground | Isolated return path for high-side output; requires separate layout from GNDB to preserve isolation. |
| VDDB | Low-side gate driver supply | 5–30 V supply for channel B; independently monitored for UVLO; may share supply with VDDA in non-isolated designs. |
| GNDB | Low-side gate driver ground | Return path for low-side output; referenced to system power ground in typical half-bridge layouts. |
| VOA | High-side gate driver output | 6 A capable voltage-source output; includes short-circuit clamp to VDDA and shutdown clamp to GNDA when unpowered. |
| VOB | Low-side gate driver output | 6 A capable voltage-source output; features identical clamping and UVLO behavior as VOA. |
| NC | No connection | Pins 12, 13, and 15 are unused; must remain floating - no routing or soldering permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive CMOS isolation | Silicon dioxide dielectric enables 6 kVRMS rating, >200 kV/µs CMTI, and lifetime stability vs. optocoupler aging. |
| Voltage-mode drive | Outputs behave as controlled voltage sources; gate speed and overshoot tuned via external resistors (no current-source complexity). |
| Programmable dead time | Resistor-based DT pin allows precise, temperature-stable dead time tuning (10–110 kΩ → ~20–200 ns) without MCU intervention. |
| Overlap protection | Hardware-level response forces both outputs low on simultaneous high inputs - eliminates shoot-through risk even with faulty controller logic. |
| AEC-Q100 qualified | Qualified to Grade 1 (–40 to +125 °C) with automotive-specific process flows - suitable for traction inverters and OBCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si82395AC-IS3R | Same Si82Ex family, dual-channel, PWM-input, but with disable (DIS) instead of enable (EN) logic polarity. | Requires inverted control signal timing; identical isolation, drive strength, and dead time capability. | Select when system controller uses active-low disable signaling or legacy design compatibility is required. |
| UCC5390SCD | Texas Instruments part with 10 A drive, single-input, but only 5 kVRMS isolation and no programmable dead time (fixed internal delay). | Lacks resistor-tunable dead time and overlap protection; requires external circuitry for shoot-through prevention. | Choose only if higher peak current is critical and dead time flexibility is not required; verify CMTI (150 kV/µs) suffices for target dv/dt. |
Compared with SI82E99ACE-IS3R, Si82395AC-IS3R offers identical performance with inverted control logic, while UCC5390SCD trades dead time programmability and reinforced isolation for higher peak current - making SI82E99ACE-IS3R optimal for automotive-grade half-bridge systems requiring hardware-enforced safety.

FAQ
What is the isolation voltage rating of the SI82E99ACE-IS3R?
The SI82E99ACE-IS3R has a certified 6 kVRMS isolation rating for one minute, compliant with UL 1577, VDE 60747-17, and CSA 62368-1 standards for reinforced insulation. Its working voltage is rated at 1500 VRMS, and it withstands bipolar surge up to 10 kV - making it suitable for high-voltage automotive and industrial power systems where galvanic separation is critical for safety and noise immunity.
Does the SI82E99ACE-IS3R support both high-side/low-side and dual independent configurations?
The SI82E99ACE-IS3R is configured exclusively as a high-side/low-side driver with a single PWM input. Unlike universal variants (e.g., SI82E29x), it does not support independent VIA/VIB control. Its pinout and truth table (Table 3 in datasheet 206857C) confirm PWM-driven complementary outputs - meaning VOA and VOB toggle inversely based on one input signal, with dead time and overlap protection enabled by default unless DT is tied to VDDI.
How is dead time programmed on the SI82E99ACE-IS3R?
Dead time on the SI82E99ACE-IS3R is programmed by connecting an external resistor (RDT) between the DT pin and GNDI. The typical dead time follows tDT = 1.73 × RDT + 5.74 ns, where RDT ranges from 10 kΩ to 110 kΩ (yielding ~20–200 ns). For zero dead time and disabled overlap protection, connect DT directly to VDDI. A 0.1 µF ceramic capacitor placed near the DT pin improves noise immunity.
What UVLO thresholds are available on the SI82E99ACE-IS3R?
The SI82E99ACE-IS3R offers factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, and matching thresholds on VDDA and VDDB (e.g., 8 V UVLO on VDDI corresponds to 8 V on VDDA/VDDB). These thresholds are fixed per device variant and selected at order time - the "ACE" suffix indicates 8 V UVLO for all rails, enabling reliable startup and shutdown behavior in 12 V automotive and 15 V industrial supply environments.
Is the SI82E99ACE-IS3R qualified for automotive applications?
Yes, the SI82E99ACE-IS3R is AEC-Q100 qualified (Grade 1, –40 to +125 °C) and built using automotive-specific manufacturing flows across wafer fabrication, assembly, and test. It carries UL, VDE, CSA, and CQC safety certifications for reinforced insulation and is explicitly listed in Skyworks' automotive-grade product portfolio for use in onboard chargers, traction inverters, and DC-DC converters in EV/HEV platforms.
