Product details
Overview
SI82E99BCC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with high-side/low-side configuration, 6 A peak output drive strength, <5 ns channel-to-channel skew, and 6 kVRMS reinforced isolation. It operates with 3–20 V logic supply and 5–30 V gate supply, and is designed for half-bridge SiC/GaN FET control in automotive-grade power inverters.
For engineers reviewing the SI82E99BCC-IS1R datasheet, SI82E99BCC-IS1R pinout, SI82E99BCC-IS1R application, or SI82E99BCC-IS1R equivalent, key selection criteria include dead-time programmability via external resistor, CMOS-compatible PWM input interface, AEC-Q100 qualification, and integrated UVLO thresholds (4/8/12/15 V) for robust motor drive and onboard charger designs.
Technical Context
The SI82E99BCC-IS1R implements a high-side/low-side topology using silicon-dioxide capacitive isolation with RF OOK modulation, delivering 200 kV/µs CMTI and 1500 VRMS working voltage. Its functional block includes independent UVLO monitors per supply rail (VDDI, VDDA, VDDB), thermal shutdown at 150 °C, and active shutdown clamps on both outputs.
It accepts a single PWM input to drive complementary outputs (VOA/VOB), with dead time controlled by an external resistor on the DT pin (10–110 kΩ range). The device enters defined low-output state during UVLO, power loss, or EN deassertion-ensuring fail-safe gate control without unknown states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577, VDE 60747-17, CSA 62368-1) |
| Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate signals |
| Output Drive Strength | 6 A peak sourcing/sinking - supports fast switching of high-capacitance SiC/GaN FETs |
| CMTI | >200 kV/µs - maintains signal integrity in noisy high-dV/dt power stages |
| UVLO Thresholds | 4 V, 8 V, 12 V, and 15 V options - configurable per supply rail to match system startup sequencing |
| Operating Temperature | –40 to +125 °C - qualified for under-hood automotive environments |
| ESD Rating | 4 kV HBM - protects against handling and board-level electrostatic discharge |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage-enhanced layout for reinforced insulation. Pinout optimized for half-bridge gate drive with dedicated PWM, DT, EN, VDDA, VDDB, VOA, VOB, and isolated ground terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWM | Single-input control signal | Drives complementary VOA/VOB outputs; enables synchronous half-bridge operation |
| EN | Active-high enable | Asserting high enables normal operation; deasserting forces both outputs low unconditionally |
| DT | Dead time programming | Resistor-connected pin sets dead time (10–110 kΩ → ~17–1100 ns); tied to VDDI disables dead time |
| VOA / VOB | Gate driver outputs | Voltage-mode outputs with 6 A peak drive; support unipolar/bipolar configurations via external resistors |
| VDDA / VDDB | Independent gate supply rails | Enable asymmetric gate drive voltages (e.g., +15 V / –5 V) for enhanced FET control |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Mode Drive | Enables precise slew-rate control via external gate resistors-optimizing EMI, switching speed, and overshoot |
| Programmable Dead Time | Adjustable 17–1100 ns dead time prevents shoot-through in half-bridge topologies without external logic |
| Fail-Safe Output States | No undefined outputs during UVLO, power loss, or EN deassertion-guarantees safe FET turn-off |
| Integrated Shutdown Clamp | Active pull-down clamp on VOA/VOB when VDDA/B is unpowered-prevents parasitic turn-on of FETs |
| AEC-Q100 Qualified | Automotive-grade reliability with full temperature range (–40 to +125 °C) and zero latent defects |

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-AB | Single-channel, 4 A output, 5 kVRMS isolation, no dead-time programming | Limited to single-leg or non-complementary drive; requires external logic for dead time | Select when only one gate driver channel is needed and cost sensitivity outweighs dual-channel integration |
| UCC5870QDWJRQ1 | 6 A dual-channel, 5.7 kVRMS isolation, integrated DESAT protection, SPI configurability | Includes desaturation detection and digital configuration-adds complexity but enables advanced protection | Choose when system-level fault diagnostics (e.g., short-circuit detection) are required beyond basic UVLO/shutdown |
Compared with SI82E99BCC-IS1R, SIL1225CD-AB lacks dual-channel integration and dead-time control, while UCC5870QDWJRQ1 adds diagnostic features at higher BOM cost and design complexity-making SI82E99BCC-IS1R optimal for cost-sensitive, high-reliability half-bridge applications needing minimal external components.

FAQ
What is the isolation architecture used in the SI82E99BCC-IS1R?
The SI82E99BCC-IS1R uses Skyworks' proprietary silicon-dioxide capacitive isolation with differential RF OOK modulation. This architecture delivers 6 kVRMS reinforced isolation, 200 kV/µs CMTI, and <5 ns channel-to-channel skew-enabling reliable operation in high-noise, high-dV/dt power converter environments without optocoupler aging or LED degradation.
Does the SI82E99BCC-IS1R support both high-side/low-side and universal configurations?
No-the SI82E99BCC-IS1R is specifically configured as a high-side/low-side driver with a single PWM input. Unlike universal variants (e.g., SI82E29x), it does not accept separate VIA/VIB inputs. Its pinout and truth table are optimized for complementary half-bridge control, with dead time programmable via the DT pin.
How is dead time programmed on the SI82E99BCC-IS1R?
Dead time on the SI82E99BCC-IS1R is set by connecting an external resistor (RDT) between the DT pin and GNDI. RDT values from 10 kΩ to 110 kΩ yield typical dead times of 17 ns to 1100 ns, calculated as tDT = 1.73 × RDT + 5.74 (ns). Connecting DT to VDDI disables dead time insertion entirely, forcing dual-driver behavior.
What UVLO thresholds are implemented in the SI82E99BCC-IS1R?
The SI82E99BCC-IS1R integrates four factory-configured UVLO thresholds: 4 V, 8 V, 12 V, and 15 V-applied independently to VDDI, VDDA, and VDDB rails. These thresholds prevent erroneous switching during brown-out conditions and ensure coordinated startup/shutdown sequencing across logic and gate drive supplies.
Is the SI82E99BCC-IS1R qualified for automotive applications?
Yes-the SI82E99BCC-IS1R is AEC-Q100 qualified (Grade 1, –40 to +125 °C) and manufactured using automotive-specific process flows. It carries UL, VDE, CSA, and CQC safety certifications for reinforced insulation, making it suitable for ASIL-B compliant systems such as EV traction inverters and onboard chargers.
