Product details
Overview
SI82E99BGC-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 used in half-bridge motor drives and SiC/GaN-based inverters requiring precise dead-time control and shoot-through protection.
For engineers reviewing the SI82E99BGC-IS1R datasheet, SI82E99BGC-IS1R pinout, SI82E99BGC-IS1R application, or SI82E99BGC-IS1R equivalent, key selection considerations include its PWM-input architecture, EN-enabled operation, programmable dead time via external resistor, 200 kV/µs CMTI, and automotive-grade AEC-Q100 qualification for onboard chargers and industrial UPS systems.
Technical Context
The SI82E99BGC-IS1R implements a PWM-input, high-side/low-side gate driver architecture using Skyworks' proprietary capacitive silicon dioxide (SiO₂) isolation. Its functional block includes dual RF-modulated OOK isolators, independent UVLO monitors per power domain (VDDI, VDDA, VDDB), and integrated dead-time control logic triggered by the DT pin.
It features voltage-mode drive outputs with active shutdown clamps, thermal shutdown at 150 °C, short-circuit clamping to VDDA/B, and CMOS-compatible Schmitt-triggered inputs with deglitch filtering. The device enforces overlap protection during simultaneous input highs and supports bootstrap or isolated gate supply topologies.
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 synchronized switching in half-bridge configurations to minimize timing-induced losses. |
| CMTI | >200 kV/µs - maintains signal integrity in high-dV/dt environments like SiC/GaN inverters and motor drives. |
| Output Drive Strength | 6 A peak sourcing/sinking - directly drives high-capacitance SiC FETs and IGBTs without external buffers. |
| Logic Input Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controllers without level-shifting. |
| Gate Supply Range | 5–30 V - supports unipolar or bipolar gate biasing for enhanced switching control and Miller immunity. |
| Dead Time Programmability | Resistor-programmable (10–110 kΩ on DT pin) - enables precise shoot-through prevention in half-bridge topologies. |
| Operating Temperature | –40 to +125 °C - qualified per AEC-Q100 Grade 1 for automotive onboard chargers and industrial motor drives. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage ≥8.3 mm and clearance ≥8.0 mm; RoHS-compliant, halogen-free, and qualified for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input power supply | Provides 3–20 V supply for internal digital circuitry and isolator modulator; UVLO threshold at 4 V (typ). |
| GNDI | Logic input ground | Reference for all logic inputs (PWM, EN); galvanically isolated from GNDA/GNDB. |
| 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. |
| EN | Active-high enable input | When low, forces VOA and VOB low regardless of PWM state - used for fast system fault shutdown. |
| DT | Dead time programming input | Connects to GNDI via resistor (10–110 kΩ) to set dead time; tied to VDDI to disable dead time and overlap protection. |
| VDDA | High-side gate driver supply | 5–30 V supply for VOA output stage; supports bootstrap or isolated supply configurations. |
| GNDA | High-side gate driver ground | Reference for VOA; isolated from GNDI and GNDB - critical for high-side floating operation. |
| VDDB | Low-side gate driver supply | 5–30 V supply for VOB; may share ground with system ground (GNDB = system GND). |
| GNDB | Low-side gate driver ground | Reference for VOB; typically connected to system power ground in half-bridge layouts. |
| VOA | High-side gate driver output | Voltage-mode output driving high-side FET gate; includes short-circuit clamp to VDDA and shutdown clamp to GNDA. |
| VOB | Low-side gate driver output | Voltage-mode output driving low-side FET gate; includes identical protection features as VOA. |
| NC | No connection | Pins 12, 13, and 14 are unconnected - must remain floating per datasheet; no internal bond wire. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive SiO₂ isolation | Enables 6 kVRMS rating, >200 kV/µs CMTI, and stable timing over temperature/age vs. optocouplers. |
| PWM-input high-side/low-side topology | Reduces controller pin count and simplifies PCB layout versus dual-input universal drivers. |
| Programmable dead time with overlap protection | Prevents shoot-through in half-bridge circuits without requiring external logic or timing ICs. |

| AEC-Q100 Grade 1 qualification | Validated for automotive applications including onboard chargers and traction inverters up to 125 °C ambient. |
| Integrated UVLO per power domain | Independent 4 V (VDDI), 8 V (VDDA), and 8 V (VDDB) thresholds prevent erratic switching during brownout conditions. |

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-IS1R | Universal configuration with VIA/VIB inputs; lacks PWM input; same SOIC-16 NB package and 6 A drive. | Suitable for designs requiring independent control of each channel (e.g., full-bridge or phase-shifted topologies). | Select when dual independent inputs are needed instead of complementary PWM control. |
| UCC5390SCD | Texas Instruments part with 10 A drive, single PWM input, and integrated Miller clamp; different 16-pin SOIC footprint. | Offers higher drive strength and active Miller clamping but lacks AEC-Q100 qualification and has lower CMTI (150 kV/µs). | Choose for non-automotive, high-current SiC applications where Miller immunity is critical and layout space permits rework. |
Compared with SI82E99BGC-IS1R, Si8239BD-IS1R provides flexible dual-input control but requires more controller resources, while UCC5390SCD delivers higher peak current and Miller clamping at the cost of automotive compliance and lower noise immunity - making SI82E99BGC-IS1R optimal for AEC-Q100-compliant, high-CMTI half-bridge systems.

FAQ
What is the isolation architecture used in the SI82E99BGC-IS1R?
The SI82E99BGC-IS1R uses Skyworks' proprietary capacitive silicon dioxide (SiO₂) isolation technology, featuring dual differential RF-modulated OOK isolators. This architecture delivers 6 kVRMS reinforced insulation, >200 kV/µs CMTI, and stable timing performance over temperature and product lifetime - unlike optocoupler-based alternatives that degrade with age and temperature.
Does the SI82E99BGC-IS1R support bootstrap gate drive for the high-side channel?
Yes, the SI82E99BGC-IS1R supports bootstrap operation for the high-side channel (VOA). VDDA can be powered via a bootstrap capacitor charged through a diode and resistor network when the low-side FET is conducting. The datasheet confirms compatibility with standard bootstrap topologies and provides design guidance in AN486.
What UVLO thresholds are implemented in the SI82E99BGC-IS1R?
The SI82E99BGC-IS1R implements three independent UVLO monitors: VDDI UVLO triggers at 4 V (typ), while VDDA and VDDB UVLO thresholds are both 8 V (typ). These thresholds prevent erroneous switching during power-up, brownout, or supply sequencing faults - ensuring VOA and VOB remain low until all supplies are within specification.
How is dead time programmed on the SI82E99BGC-IS1R?
Dead time on the SI82E99BGC-IS1R is programmed by connecting an external resistor (RDT) between the DT pin and GNDI. RDT values from 10 kΩ to 110 kΩ yield typical dead times from ~25 ns to ~650 ns, calculated using tDT = 1.73 × RDT + 5.74 (ns, RDT in kΩ). Connecting DT to VDDI disables dead time and overlap protection.
Is the SI82E99BGC-IS1R qualified for automotive applications?
Yes, the SI82E99BGC-IS1R is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C ambient), manufactured using automotive-specific process flows, and certified to UL, VDE, CSA, and CQC reinforced insulation standards. It is explicitly intended for automotive applications including onboard chargers, DC-DC converters, and traction inverters.
