Product details
Overview
SI82E99BCE-IS3 from Skyworks Solutions is a dual-channel isolated gate driver with high-side/low-side configuration, 6 A peak output drive capability, <5 ns channel-to-channel skew, and 6 kVRMS reinforced isolation. It operates with 3–20 V logic supply and up to 30 V gate supply, and is designed for half-bridge SiC/GaN/MOSFET/IGBT control in onboard chargers and motor drives.
For engineers reviewing the SI82E99BCE-IS3 datasheet, SI82E99BCE-IS3 pinout, SI82E99BCE-IS3 application, or SI82E99BCE-IS3 equivalent, key selection considerations include its programmable dead time (via DT pin), CMOS-compatible PWM input architecture, automotive-grade AEC-Q100 qualification, and 200 kV/µs CMTI for noisy power stage environments.
Technical Context
The SI82E99BCE-IS3 implements a high-side/low-side gate driver topology using differential capacitive isolation with RF OOK modulation across dual SiO₂ barriers, enabling precise timing control and fault tolerance. Its PWM input architecture synchronizes both outputs with inherent overlap protection triggered by simultaneous high inputs.
Dead time is user-programmed via an external resistor on the DT pin (10–110 kΩ), generating 1.73×RDT + 5.74 ns typical delay, and can be disabled by connecting DT to VDDI. UVLO thresholds are fixed at 4 V (VDDI), 8 V (VDDA), and 8 V (VDDB), with independent monitoring per supply rail.
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-to-Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate drive signals in half-bridge topologies. |
| CMTI | >200 kV/µs - suppresses false triggering during fast dV/dt transients in SiC/GaN-based inverters. |
| Output Drive Strength | 6 A peak sourcing/sinking - supports fast switching of high-capacitance wide-bandgap FETs without external buffers. |
| Logic Input Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller interfaces without level-shifting. |
| Gate Supply Range | 5–30 V - enables flexible biasing for unipolar or bipolar gate drive configurations (e.g., +15 V/–5 V). |
| Operating Temperature | –40 to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
| ESD Rating | 4 kV HBM - provides robust handling during PCB assembly and system integration. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage ≥8.3 mm and clearance ≥8.3 mm; RoHS-compliant, halogen-free, and automotive-qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input power supply | Supplies 3–20 V to internal digital circuitry; triggers UVLO if ≤4 V. |
| GNDI | Logic input ground reference | Isolated return path for digital side; must be separated from GNDA/GNDB by ≥8.3 mm creepage. |
| PWM | Single-input control signal | Drives VOA high / VOB low when high; VOA low / VOB high when low - enables half-bridge complementary operation. |
| EN | Active-high enable input | When low, forces VOA and VOB low unconditionally; resumes normal operation within tEID after rising edge. |
| DT | Dead time programming terminal | Resistor-to-GND sets dead time (1.73×RDT + 5.74 ns); tied to VDDI disables dead time and overlap protection. |
| VDDA | High-side gate driver supply | 5–30 V supply for VOA output; UVLO activates at ≤8 V to prevent weak turn-on of high-side FET. |
| GNDA | High-side gate driver ground | Return path for high-side output; electrically isolated from GNDI and GNDB. |
| VDDB | Low-side gate driver supply | 5–30 V supply for VOB output; independent UVLO at ≤8 V ensures safe low-side operation. |
| GNDB | Low-side gate driver ground | Return path for low-side output; isolated from GNDI and GNDA. |
| VOA | High-side gate driver output | 6 A capable voltage-source output; includes short-circuit clamp to VDDA and shutdown clamp to GNDA. |
| VOB | Low-side gate driver output | 6 A capable voltage-source output; features identical clamping and thermal protection as VOA. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Dead Time | Configurable 0–120 ns via external resistor on DT pin; prevents shoot-through in half-bridge circuits. |
| Overlap Protection | Hardware-enforced immediate low-state on both VOA/VOB when PWM goes high while either output is already high. |
| Voltage Mode Drive | Output behaves as controlled voltage source; gate resistor selection directly tunes rise/fall times and EMI. |
| Independent UVLO Monitoring | Dedicated 4 V (VDDI), 8 V (VDDA), and 8 V (VDDB) thresholds ensure safe operation even if one supply fails. |
| Thermal Shutdown | Auto-recovering shutdown at TSD+ = 150 °C; weak pull-down until temperature falls below TSD− = 135 °C. |
| Shutdown Clamp | Active pull-down to GNDA/GNDB when VDDA/VDDB is unpowered - prevents parasitic FET turn-on during startup/shutdown. |
Applications
| Onboard Charger (OBC) | 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 |
|---|---|---|---|
| Si8239BD-IS3 | Same SOIC-16 NB package and PWM input architecture, but lacks AEC-Q100 qualification and has fixed 8 V UVLO on VDDA/VDDB (vs. SI82E99BCE-IS3's 8 V UVLO). | Targeted at industrial UPS and server PSUs where automotive qualification is unnecessary. | Select when AEC-Q100 is not required and cost sensitivity outweighs extended temperature margin. |
| UCC5390SCD | TI part with 10 A peak drive, single 5–25 V gate supply, and integrated Miller clamp; no programmable DT pin or dual UVLO thresholds. | Optimized for high-current GaN half-bridges requiring active Miller clamping, not universal high-side/low-side flexibility. | Choose when higher peak current and Miller clamping are critical, and dead time tuning is handled externally. |
Compared with Si8239BD-IS3, SI82E99BCE-IS3 adds automotive qualification and tighter UVLO tolerances; versus UCC5390SCD, it trades peak current for design flexibility in dead time control, dual-rail gate supplies, and independent UVLO monitoring - making it preferable for thermally constrained, safety-critical half-bridge systems.

FAQ
What is the function of the DT pin on the SI82E99BCE-IS3?
The DT pin on the SI82E99BCE-IS3 programs dead time between VOA and VOB transitions using an external resistor to GND (10–110 kΩ), yielding 1.73×RDT + 5.74 ns typical delay. Connecting DT to VDDI disables dead time and overlap protection, allowing the SI82E99BCE-IS3 to operate as a dual independent driver. This pin is essential for preventing shoot-through in half-bridge configurations.
Does the SI82E99BCE-IS3 support bipolar gate drive voltages?
Yes, the SI82E99BCE-IS3 supports bipolar gate drive through independent VDDA and VDDB supplies. By applying +15 V to VDDA and –5 V to VDDB (with appropriate level-referenced grounds), the SI82E99BCE-IS3 can generate +15 V/–5 V gate drive for enhanced SiC FET turn-off robustness. The device's voltage-mode architecture and shutdown clamp ensure safe operation during polarity transitions.
How does the SI82E99BCE-IS3 handle undervoltage conditions on its power supplies?
The SI82E99BCE-IS3 implements independent UVLO monitoring: VDDI enters lockout below 4 V, while VDDA and VDDB each trigger at 8 V. When any supply drops below its threshold, the corresponding output (VOA or VOB) is forced low. If VDDI is in UVLO, both VOA and VOB remain low regardless of input state - ensuring fail-safe behavior during brownouts or startup sequences in the SI82E99BCE-IS3.
What isolation certifications apply to the SI82E99BCE-IS3?
The SI82E99BCE-IS3 is certified to UL 1577 (6000 VRMS, 1 min), VDE 60747-17 (reinforced insulation), CSA 62368-1 (reinforced), and CQC GB4943.1. These approvals confirm its suitability for safety-critical applications including automotive onboard chargers and medical power supplies requiring two means of patient protection (2 MOPP) per IEC 60601-1.
Can the SI82E99BCE-IS3 drive both SiC and IGBT power devices?
Yes, the SI82E99BCE-IS3 is explicitly validated for SiC FETs, IGBTs, MOSFETs, and GaN HEMTs. Its 6 A peak sourcing/sinking current, 30 V max gate supply, and voltage-mode drive architecture allow direct interfacing with diverse gate charge requirements. The SI82E99BCE-IS3's 200 kV/µs CMTI and low skew further ensure reliable switching in high-dV/dt SiC inverters and high-current IGBT modules.
