Product details
Overview
SI82F99BCC-IS1 from Skyworks Solutions is a dual-channel isolated gate driver in High-Side/Low-Side configuration with PWM 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 topologies for onboard chargers and motor inverters.
For engineers reviewing the SI82F99BCC-IS1 datasheet, SI82F99BCC-IS1 pinout, SI82F99BCC-IS1 application, or SI82F99BCC-IS1 equivalent, key selection considerations include its PWM-based control architecture, integrated Miller clamp, programmable dead time via external resistor, automotive-grade AEC-Q100 qualification, and 1500 VRMS working voltage compliance with IEC 62368-1 and IEC 60601-1.
Technical Context
The SI82F99BCC-IS1 implements differential capacitive isolation using silicon dioxide barriers, enabling RF-modulated signal transmission with 200 kV/µs CMTI and minimal timing drift over temperature. Its PWM input architecture directly controls complementary outputs VOA and VOB with overlap protection triggered by simultaneous high inputs.
Dead time is set by an external resistor on DT pin (10–110 kΩ), yielding 17.3–190 ns typical delay; connecting DT to VDDI disables dead time insertion. SelVCD™ uses SPD+ and SPD− pins to configure sourcing/sinking current independently across eight levels, with built-in Miller clamp engaging below VMCTA/B (~1.9 V) during turn-off transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 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. |
| Input Supply Range | 3 V to 20 V - supports direct interface with 3.3 V, 5 V, and 12 V logic controllers without level shifting. |
| Gate Supply Range | 5 V to 30 V - enables direct drive of SiC FETs requiring ≥15 V gate bias and GaN devices needing precise turn-on voltage control. |
| CMTI | >200 kV/µs - prevents false triggering in noisy high-dV/dt environments such as motor drives and inverters. |
| UVLO Threshold | 15 V nominal - provides robust startup/shutdown sequencing for gate driver supplies in high-voltage power stages. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1. |
Pinout & Package
SI82F99BCC-IS1 is housed in a narrow-body 16-pin SOIC package (NB SOIC-16) with creepage ≥8.3 mm and clearance ≥8.3 mm. Pin 1 is VIA; pins 12 and 13 are NC; all other pins match Figure 4 in the preliminary datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input | Not used in SI82F99x; reserved for Universal-config variants - left unconnected in this PWM-input device. |
| PWM | Single logic input for both channels | Drives VOA high / VOB low when high; VOA low / VOB high when low - enables compact half-bridge control with one signal line. |
| EN | Active-high enable | Asserting EN = high enables normal operation; deasserting forces VOA/VOB low - provides fail-safe shutdown independent of PWM state. |
| DT | Dead time programming | Resistor-to-GND sets 17–190 ns dead time; connection to VDDI disables dead time - allows flexible half-bridge timing tuning or dual-driver reconfiguration. |
| SPD+ | Sourcing current control | Selects one of eight output sourcing current levels (e.g., 0.5 A to 6 A typical) - eliminates external gate resistors for SiC/GaN turn-on optimization. |
| SPD− | Sinking current control | Selects one of eight output sinking current levels - enables independent turn-off speed control and active Miller clamping at VOA/VOB. |
| VDDA / GNDA | High-side gate supply | Provides isolated 5–30 V power to drive high-side switch - decoupled from low-side supply to prevent shoot-through coupling. |
| VDDB / GNDB | Low-side gate supply | Provides isolated 5–30 V power to drive low-side switch - supports asymmetric bootstrap or floating supply configurations. |
| VOA / VOB | Gate driver outputs | Current-source outputs with integrated Miller clamp - clamp engages below ~1.9 V during turn-off to suppress parasitic turn-on in SiC/GaN devices. |
Key Features
| Feature | Design Value |
|---|---|
| High-Side/Low-Side PWM Configuration | Dedicated single-input control for complementary half-bridge outputs - reduces MCU GPIO count and simplifies gate timing in inverter designs. |
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels per channel - replaces gate resistors while maintaining ±10% current accuracy over temp and process variation. |
| Integrated Miller Clamp | Automatically activates below VMCTA/B (~1.9 V) during VOA/VOB turn-off - prevents dv/dt-induced parasitic turn-on in wide-bandgap FETs without external components. |
| Programmable Dead Time | Resistor-controlled 17–190 ns delay between VOA/VOB transitions - configurable via DT pin to match specific power device switching characteristics. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C) qualification with automotive-specific manufacturing flow - ensures reliability for EV traction inverters and OBCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8239BD-IS1 | Universal configuration with VIA/VIB inputs; no PWM input; same NB SOIC-16 package and 6 kVRMS isolation. | Requires two independent logic signals instead of one PWM - better suited for synchronous rectification or non-complementary topologies. | Select Si8239BD-IS1 only if dual independent inputs are needed; SI82F99BCC-IS1 is optimal for compact half-bridge control with single-PWM timing. |
| UCC5390SCD | TI device with 5.7 kVRMS isolation, 35 V max VDD, and fixed 4 A/6 A sourcing/sinking - no SelVCD™ or SPD± programming. | Lacks programmable current drive and Miller clamp - requires external gate resistors and separate Miller clamp circuitry for SiC/GaN. | Choose UCC5390SCD for cost-sensitive industrial applications where fixed-current drive suffices; SI82F99BCC-IS1 delivers superior SiC/GaN optimization with integrated features. |
Compared with Si8239BD-IS1 and UCC5390SCD, SI82F99BCC-IS1 uniquely combines PWM-based half-bridge control, eight-level SelVCD™, and active Miller clamping in a single AEC-Q100-qualified package - reducing BOM count and improving reliability in automotive and high-density power systems.

FAQ
What is the function of the DT pin on the SI82F99BCC-IS1?
The DT pin on the SI82F99BCC-IS1 programs dead time between VOA and VOB transitions using an external resistor (10–110 kΩ) to GND, yielding 17–190 ns typical delay. Connecting DT to VDDI disables dead time insertion and overlap protection, allowing the SI82F99BCC-IS1 to operate as a dual independent driver rather than a half-bridge controller.
Does the SI82F99BCC-IS1 support SiC and GaN power devices?
Yes, the SI82F99BCC-IS1 supports SiC and GaN FETs through its 5–30 V gate supply range, eight-level SelVCD™ for precise turn-on/turn-off current control, and integrated Miller clamp that activates below ~1.9 V to suppress parasitic turn-on - eliminating need for external Miller clamp circuits or gate resistors in wide-bandgap designs.
What safety certifications apply to the SI82F99BCC-IS1?
The SI82F99BCC-IS1 carries pending certifications including UL 1577 (6000 VRMS, 1 min), CSA 62368-1 (reinforced insulation), CSA 60601-1 (2 MOPP), VDE 60747-17 (reinforced insulation), and CQC GB4943.1 - all enabled by its 6 kVRMS silicon capacitive isolation barrier and 1500 VRMS working voltage rating.
How does the SelVCD™ feature eliminate gate resistors in the SI82F99BCC-IS1?
SelVCD™ in the SI82F99BCC-IS1 replaces gate resistors by implementing sourcing and sinking current as tightly regulated current sources controlled via SPD+ and SPD− pins. Each pin selects one of eight discrete current levels (e.g., 0.5 A to 6 A), maintaining ±10% accuracy over temperature and process - enabling direct gate drive without external components while preserving Miller clamp effectiveness.
Is the SI82F99BCC-IS1 pin-compatible with other Si82Fx variants?
No, the SI82F99BCC-IS1 is not pin-compatible with Universal-configuration Si82Fx variants (e.g., Si8239x) due to its dedicated PWM input replacing VIA/VIB pins. However, it shares the same NB SOIC-16 footprint and isolation barrier specifications with other Si82F99x devices - requiring PCB redesign only when migrating from VIA/VIB to PWM control architecture.
