Product details
Overview
SI82E99BEC-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/MOSFET/IGBT control in onboard chargers and motor drives.
For engineers reviewing the SI82E99BEC-IS1R datasheet, SI82E99BEC-IS1R pinout, SI82E99BEC-IS1R application, or SI82E99BEC-IS1R equivalent, key selection considerations include its PWM-input architecture, programmable dead time via DT pin, AEC-Q100 qualification, 200 kV/µs CMTI, and narrow-body SOIC-16 automotive-grade package.
Technical Context
The SI82E99BEC-IS1R implements a high-side/low-side PWM-input topology using capacitive silicon dioxide (SiO₂) isolation with RF OOK modulation. Its functional block includes dual independent UVLO monitors (VDDI, VDDA, VDDB), integrated dead time control via external resistor on DT pin, and shutdown clamps active during unpowered gate supply conditions.
This variant uses a single PWM input to drive complementary outputs (VOA high / VOB low or vice versa), with overlap protection triggered when both inputs would cause simultaneous high-side and low-side conduction. It features CMOS-compatible Schmitt-triggered inputs with deglitch filtering option and thermal shutdown at 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute - certified reinforced insulation per UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1. |
| Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate drive edges for shoot-through prevention. |
| CMTI | >200 kV/µs - enables reliable operation in high-dV/dt environments like SiC/GaN inverters without false triggering. |
| Output Drive | 6 A peak sourcing/sinking - supports fast switching of high-capacitance wide-bandgap FETs with external gate resistors. |
| Operating Temp | –40 to +125 °C - rated for under-hood automotive and industrial power converter environments. |
| UVLO Thresholds | VDDI: 4 V (falling), 4.5 V (rising); VDDA/VDDB: 8 V (falling), 9 V (rising) - prevents erratic gate drive during brown-out conditions. |
| Dead Time Range | Programmable 0–500 ns via 10–110 kΩ resistor on DT pin - allows tuning to match FET turn-on/off delays and prevent cross-conduction. |
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 to AEC-Q100 Grade 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWM | Single logic input for complementary outputs | Drives VOA high / VOB low when high; VOA low / VOB high when low - eliminates need for external logic inversion in half-bridge control. |
| EN | Active-high enable control | When low, forces both VOA and VOB low regardless of PWM state - enables fast system-level fault shutdown. |
| DT | Dead time programming terminal | Resistor to GNDI sets delay between VOA/VOB transitions; connection to VDDI disables dead time for dual-driver mode. |
| VDDI | Logic-side supply (3–20 V) | Power for input circuitry and isolation barrier modulator; includes UVLO monitoring at 4 V/4.5 V thresholds. |
| GNDI | Logic-side ground reference | Reference for PWM, EN, and DT signals; galvanically isolated from GNDA/GNDB by SiO₂ capacitors. |
| VDDA / GNDA | High-side gate driver supply/ground | Provides isolated 5–30 V power to VOA output stage; UVLO active independently from VDDB side. |
| VDDB / GNDB | Low-side gate driver supply/ground | Provides isolated 5–30 V power to VOB output stage; supports bootstrap or isolated supply topologies. |
| VOA / VOB | Complementary gate drive outputs | Voltage-mode outputs with 6 A peak drive; include short-circuit clamp to VDDA/VDDB and shutdown clamp to GNDA/GNDB. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation | 6 kVRMS rating with 1500 VRMS working voltage - meets safety requirements for EV traction inverters and industrial UPS systems. |
| Programmable Dead Time | 0–500 ns via single external resistor - eliminates need for external timing ICs or complex PCB routing in half-bridge designs. |
| Overlap Protection | Hardware-enforced immediate low-state on both outputs if PWM and EN simultaneously assert conflicting states - prevents shoot-through without software intervention. |
| Voltage-Mode Drive | Output current controlled solely by external gate resistors - simplifies layout, enables independent optimization of rise/fall times and EMI. |
| AEC-Q100 Qualified | Grade 1 (–40 to +125 °C) with automotive-specific manufacturing flow - supports ASIL-B system integration in OBC and DC-DC converters. |
| Robust Input Interface | CMOS/Schmitt-triggered PWM/EN inputs with optional deglitch filter - tolerates noisy MCU outputs and reduces susceptibility to EFT bursts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si82E99AD-IS1R | Same pinout and PWM-input architecture, but with 4 V/4.5 V VDDI UVLO and no deglitch filter - lower propagation delay variation across temperature. | Preferred for cost-sensitive industrial SMPS where extended deglitch is unnecessary and tighter timing stability is required. | Select when minimal input-to-output delay drift (<±0.5 ns over –40 to 125 °C) is critical and system noise immunity is managed at controller level. |
| UCC5390SCDR | TI device with single PWM input, 5 A drive, 3.75 kVRMS isolation, and integrated Miller clamp - lacks programmable dead time and automotive qualification. | Suitable for non-automotive 48 V–400 V industrial inverters where reinforced insulation is not mandated and board space is constrained. | Choose only if UL/VDE reinforced insulation is not required and design can accept fixed 100 ns dead time plus external Miller clamp implementation. |
Compared with SI82E99BEC-IS1R, Si82E99AD-IS1R offers tighter timing stability but less noise immunity, while UCC5390SCDR provides smaller footprint and Miller clamping at the cost of reduced isolation rating and no AEC-Q100 support - making SI82E99BEC-IS1R the optimal choice for automotive OBC and high-reliability industrial UPS.

FAQ
What is the isolation architecture used in SI82E99BEC-IS1R?
The SI82E99BEC-IS1R uses capacitive silicon dioxide (SiO₂) isolation with differential RF OOK modulation across two redundant high-voltage capacitors. This architecture delivers 6 kVRMS reinforced isolation, >200 kV/µs CMTI, and <5 ns channel skew - significantly outperforming optocouplers in timing precision and lifetime reliability. The isolation barrier is certified to UL, VDE, CSA, and CQC safety standards.
Does SI82E99BEC-IS1R support both high-side/low-side and dual independent configurations?
No - SI82E99BEC-IS1R is specifically configured as a high-side/low-side driver with a single PWM input. It does not support independent VIA/VIB control. To achieve dual independent operation, a Universal-configuration part such as SI82E39BEC-IS1R must be selected. The SI82E99BEC-IS1R's DT pin can disable dead time when tied to VDDI, but it remains a complementary-output device.
What is the function of the EN pin on SI82E99BEC-IS1R?
The EN (Enable) pin on SI82E99BEC-IS1R is an active-high signal that controls functional operation: when logic high, the device processes the PWM input normally; when logic low, it forces both VOA and VOB outputs low within tDID (max 35 ns), regardless of PWM state or power supply conditions. This provides deterministic, hardware-level fault shutdown for system-level protection.
How is dead time programmed on SI82E99BEC-IS1R?
Dead time on SI82E99BEC-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 from ~20 ns to ~500 ns, calculated as tDT = 1.73 × RDT + 5.74 (ns). A 0.1 µF ceramic capacitor placed directly at the DT pin improves noise immunity. Connecting DT to VDDI disables dead time insertion entirely.
Is SI82E99BEC-IS1R qualified for automotive applications?
Yes - SI82E99BEC-IS1R is AEC-Q100 qualified Grade 1 (–40 to +125 °C ambient), manufactured using automotive-specific process flows, and certified to 2 MOPP per IEC 60601-1 and reinforced insulation per IEC 62368-1. It is explicitly intended for automotive applications including onboard chargers, DC-DC converters, and traction inverter auxiliary supplies.
