For engineers reviewing the SI82E99AGC-IS1 datasheet, SI82E99AGC-IS1 pinout, SI82E99AGC-IS1 application, or SI82E99AGC-IS1 equivalent, this page delivers verified specifications, functional pin mapping, safety-certified isolation performance, dead-time programmability, and automotive-grade thermal and UVLO behavior - all confirmed for the exact SI82E99AGC-IS1 variant.
Technical Context
The SI82E99AGC-IS1 implements a High-Side/Low-Side configuration using PWM input (pin 1), EN enable control (pin 11), and DT dead-time programming (pin 10). Its capacitive isolation uses dual SiO₂ barriers with OOK modulation, delivering 200 kV/μs CMTI and deterministic timing across temperature.
It features independent UVLO thresholds per supply rail (VDDI, VDDA, VDDB), active shutdown clamps on unpowered outputs, and short-circuit clamping to VDDA/B. The device enters thermal shutdown at 150 °C and resets at 140 °C, with guaranteed operation from –40 to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 6 kVRMS for 1 minute (UL 1577), reinforced insulation per IEC 62368-1 & IEC 60747-17 |
| Channel-to-Channel Skew | <5 ns - ensures precise timing alignment between high-side and low-side gate drive edges |
| Peak Output Current | 6 A sourcing/sinking - supports fast switching of SiC/GaN FETs in high-frequency half-bridge topologies |
| CMTI | >200 kV/μs - prevents false triggering in noisy power-conversion environments with rapid dV/dt transients |
| Dead Time Programmability | Resistor-programmable (10–110 kΩ on DT pin) - enables adjustable shoot-through prevention without external logic |
| Operating Temperature | –40 °C to +125 °C - validated for under-hood automotive applications including OBC and traction inverters |
| UVLO Thresholds | VDDI: 4 V (fall), 4.5 V (rise); VDDA/VDDB: 8 V (fall), 9 V (rise) - prevents erratic gate drive during brown-out conditions |
Pinout & Package
Narrow-body SOIC-16 package (7.5 mm × 10.3 mm, 1.27 mm pitch) with creepage ≥8.3 mm and clearance ≥8.0 mm per IEC 60664-1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PWM) | Single logic input for both channels | Drives VOA high / VOB low when high; VOA low / VOB high when low - simplifies controller interface in half-bridge mode |
| 10 (DT) | Dead time programming terminal | Resistor-to-GND sets delay between VOA/VOB transitions; connection to VDDI disables dead time for dual-driver use |
| 11 (EN) | Active-high enable control | Asserting high enables normal operation; pulling low forces VOA/VOB low within 25 ns - critical for fault-safe shutdown |
| 2 (VDDA) | High-side gate driver supply | Accepts 5–30 V; powers internal high-side output stage and enables bootstrap-compatible operation |
| 4 (GNDA) | High-side ground reference | Isolated return path for high-side driver - must be separated from GNDB and GNDI to maintain isolation integrity |
| 5 (VDDB) | Low-side gate driver supply | Independent 5–30 V supply for low-side output stage - allows asymmetrical voltage rails for optimized FET biasing |
| 7 (GNDB) | Low-side ground reference | Isolated return for low-side driver; electrically distinct from GNDA and GNDI to preserve channel separation |
| 8 (VDDI) | Logic input supply | 3–20 V CMOS-compatible rail powering input circuitry, isolation modulator, and internal regulators |
| 9 (GNDI) | Logic input ground | Reference for PWM, EN, DT inputs - galvanically isolated from GNDA/GNDB to prevent ground-loop coupling |
| 12 (VOA) | High-side gate driver output | 6 A capable voltage-source output - directly drives high-side FET gate with controlled slew via external RG |
| 13 (VOB) | Low-side gate driver output | 6 A capable voltage-source output - drives low-side FET with matched propagation delay and skew to VOA |
| 14 (VIB) | Not connected (NC) | No internal bond; must remain unconnected - avoids unintended signal coupling or ESD path disruption |
| 15 (VIA) | Not connected (NC) | No internal bond; must remain unconnected - confirms SI82E99AGC-IS1 uses PWM-input architecture, not dual-input |
| 16 (VDDI) | Redundant logic supply pin | Second VDDI connection for improved decoupling and current sharing - requires local 0.1 µF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| High-Side/Low-Side PWM Configuration | Single PWM input controls complementary outputs with built-in overlap protection - eliminates need for external logic or gate delays |
| Voltage-Mode Drive Architecture | Output behaves as controllable voltage source - enables predictable gate charging/discharging using standard gate resistors |
| Programmable Dead Time | Adjustable 20–200 ns delay via external resistor on DT pin - prevents shoot-through without compromising switching frequency |
| Automotive-Grade Thermal Protection | Thermal shutdown at 150 °C with hysteresis (10 °C); resumes operation only after cooling to 140 °C - ensures reliability in sealed enclosures |
| Robust UVLO per Power Rail | Independent monitoring of VDDI, VDDA, and VDDB - guarantees safe output state even if only one supply fails |
| Shutdown Clamp on Unpowered Outputs | Active pull-down to GNDA/GNDB when VDDA/VDDB = high-Z - prevents parasitic turn-on of FETs during power sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated high-side/low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si82E99AD-IS1 | Same SOIC-16 package and PWM-input architecture, but with 4 V UVLO on VDDI (vs. 4.5 V rise in SI82E99AGC-IS1) and no AEC-Q100 qualification | Targeted at industrial SMPS and motor drives where automotive qualification is unnecessary | Select when cost sensitivity outweighs automotive compliance and tighter UVLO hysteresis is acceptable |
| UCC5390SCDR | Texas Instruments part with 10 A peak drive, single-channel + isolated level-shift architecture, and integrated Miller clamp - differs in topology and pinout | Used in high-power server PSUs and industrial welders requiring higher drive strength and active Miller clamping | Choose only when redesigning for higher current or needing Miller clamping; not a drop-in replacement |
Compared with SI82E99AGC-IS1, Si82E99AD-IS1 offers identical functionality without automotive qualification or enhanced UVLO margins, while UCC5390SCDR provides higher drive capability but requires board-level rearchitecture due to non-compatible pinout and single-channel + level-shifter topology.

FAQ
What is the isolation architecture used in the SI82E99AGC-IS1?
The SI82E99AGC-IS1 employs capacitive isolation using dual silicon-dioxide (SiO₂) barriers with on-off keying (OOK) modulation. This architecture delivers 6 kVRMS reinforced isolation, 200 kV/μs common-mode transient immunity, and <5 ns channel-to-channel skew - all verified per UL 1577, VDE 60747-17, and IEC 62368-1 standards. Unlike optocouplers, it exhibits minimal drift over temperature and lifetime.
Does the SI82E99AGC-IS1 support both high-side/low-side and dual independent configurations?
No - the SI82E99AGC-IS1 is fixed to High-Side/Low-Side configuration with a single PWM input (pin 1). It does not support dual independent inputs (VIA/VIB). The device achieves complementary output behavior natively: PWM high → VOA high / VOB low; PWM low → VOA low / VOB high. Universal configuration variants (e.g., SI82E39x) use VIA/VIB inputs instead.
How is dead time programmed on the SI82E99AGC-IS1, and what is its range?
Dead time is programmed by connecting an external resistor (RDT) between pin 10 (DT) and GNDI. Using Equation tDT = 1.73 × RDT + 5.74 (with RDT in kΩ), values from 10 kΩ to 110 kΩ yield typical dead times of 23 ns to 196 ns. Connecting DT to VDDI disables dead time insertion entirely, forcing dual-driver behavior - though this is not the intended use case for SI82E99AGC-IS1.
What are the UVLO thresholds for each supply rail in the SI82E99AGC-IS1?
The SI82E99AGC-IS1 has three independent UVLO monitors: VDDI enters UVLO at ≤4.0 V and exits at >4.5 V; VDDA and VDDB each enter UVLO at ≤8.0 V and exit at >9.0 V. These thresholds are factory-trimmed and guaranteed over temperature. When any supply is in UVLO, its associated output (VOA or VOB) is forced low, preventing partial drive conditions that could damage power switches.
Is the SI82E99AGC-IS1 pin-compatible with other Si82Ex family members like SI82E29 or SI82E89?
No - SI82E99AGC-IS1 is not pin-compatible with SI82E29x or SI82E89x variants. While all share the SOIC-16 package, pin functions differ: SI82E99AGC-IS1 uses PWM (pin 1) and EN (pin 11), whereas SI82E29x uses VIA (pin 1) and DIS (pin 11). Substituting without board revision risks incorrect logic behavior or loss of safety features. Always verify pin mapping against the specific ordering part number.
