Product details
Overview
SI82E99BBC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with high-side/low-side configuration, 6 A peak output drive capability, <5 ns channel-to-channel skew, and 6 kVRMS reinforced isolation. It operates with 3–20 V logic supply and supports up to 30 V gate drive voltage, enabling robust control of SiC and GaN FETs in half-bridge motor inverters.
For engineers reviewing the SI82E99BBC-IS1R datasheet, SI82E99BBC-IS1R pinout, SI82E99BBC-IS1R application, or SI82E99BBC-IS1R equivalent, this page delivers verified functional identity, validated SOIC-16 narrow-body package mapping, confirmed CMOS input interface with EN control, exact UVLO thresholds (4/8/12/15 V options), and two rigorously cross-checked alternative parts for half-bridge gate driving.
Technical Context
The SI82E99BBC-IS1R implements capacitive silicon-dioxide isolation with differential RF-modulated OOK signaling, delivering 200 kV/µs CMTI and stable timing across –40 to 125 °C. Its high-side/low-side architecture uses a single PWM input with dedicated DT pin for resistor-programmable dead time, preventing shoot-through in half-bridge topologies.
It features independent UVLO monitoring on VDDI, VDDA, and VDDB, active shutdown clamps on VOA/VOB during unpowered states, and thermal shutdown with hysteresis (TSD+ = 150 °C, TSD– = 135 °C). The EN input provides synchronous enable/disable control with tDID ≤ 25 ns disable delay and tEID ≤ 35 ns enable recovery.
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 outputs in half-bridge switching |
| Peak Output Current | ±6 A - sufficient to rapidly charge/discharge high-Qg SiC/GaN FET gates without external buffers |
| CMTI | >200 kV/µs - maintains signal integrity in noisy high-dV/dt power converter environments |
| Logic Supply Range | 3–20 V - compatible with 3.3 V, 5 V, and 15 V controller interfaces without level-shifting |
| Gate Supply Range | 5–30 V - supports bipolar gate drive (e.g., +15 V/–5 V) and wide-range bootstrap operation |
| UVLO Thresholds | Configurable at 4 V, 8 V, 12 V, or 15 V - prevents erratic switching during brown-out or startup |
Pinout & Package
Narrow-body 16-pin SOIC (SOIC-16NB) package with 1.27 mm pitch, creepage ≥ 8.3 mm, clearance ≥ 8.3 mm, and reinforced insulation barrier between logic and power sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDI | Logic input power supply | Provides 3–20 V bias for internal digital circuitry and isolation modulator |
| GNDI | Logic input ground | Reference return for all digital inputs; galvanically isolated from power grounds |
| PWM | Single-input control signal | Drives both channels in complementary mode; enables compact half-bridge control |
| EN | Active-high enable | Asserting high enables normal operation; pulling low forces VOA/VOB low within 25 ns |
| DT | Dead time programming input | Resistor-to-GND sets dead time (10–110 kΩ → 18–200 ns); tied to VDDI disables dead time |
| VDDA | High-side gate driver supply | Supplies 5–30 V to drive high-side FET; supports bootstrap or isolated supply |
| GNDA | High-side gate driver ground | Local reference for high-side output; floats with high-side switching node |
| VDDB | Low-side gate driver supply | Supplies 5–30 V to drive low-side FET; referenced to system power ground |
| GNDB | Low-side gate driver ground | System ground reference for low-side output; electrically common with controller ground |
| VOA | High-side gate driver output | ±6 A voltage-mode output; includes short-circuit clamp to VDDA and shutdown clamp to GNDA |
| VOB | Low-side gate driver output | ±6 A voltage-mode output; includes identical protection features as VOA |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Mode Drive | Eliminates need for external current-sense resistors; gate speed and overshoot controlled via simple Rg selection |
| Programmable Dead Time | Resistor-adjustable 18–200 ns range with overlap protection - prevents shoot-through without firmware intervention |
| Robust UVLO Architecture | Independent monitors on VDDI, VDDA, and VDDB with hysteresis - guarantees safe turn-off during partial power loss |
| Thermal Shutdown with Hysteresis | Triggers at 150 °C, resets at 135 °C - protects against sustained overload while allowing recovery after transient heating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side isolated gate driving applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs SI8239BB-IS1R | Same SOIC-16NB package, 4 A peak drive, 10 ns skew, no deglitch filter option | Limited to lower-power IGBT/Si-MOSFET designs; lacks 6 A drive for fast SiC/GaN switching | Select when cost sensitivity outweighs need for 6 A drive and sub-5 ns skew in non-automotive applications |
| TI UCC5390SCDWR | SOIC-16WB package, 6 A drive, 15 ns skew, integrated Miller clamp, no programmable DT pin | Requires external dead-time logic or MCU coordination; wider body increases PCB area | Prefer when Miller clamping is mandatory and fixed 15 ns dead time suffices for topology constraints |
Compared with SI82E99BBC-IS1R, SI8239BB-IS1R trades drive strength and timing precision for lower cost, while UCC5390SCDWR adds Miller clamping but sacrifices dead-time programmability and package footprint efficiency - making SI82E99BBC-IS1R optimal for space-constrained, high-frequency SiC half-bridges requiring deterministic shoot-through prevention.

FAQ
What is the isolation voltage rating of the SI82E99BBC-IS1R?
The SI82E99BBC-IS1R is safety-certified for 6 kVRMS isolation for one minute per UL 1577, with reinforced insulation validated to IEC 62368-1, IEC 60747-17, and GB4943.1. This rating applies across its full operating temperature range (–40 to 125 °C) and supports working voltages up to 1500 VRMS, making it suitable for 1200 V SiC and 1700 V IGBT systems.
Does the SI82E99BBC-IS1R support both high-side/low-side and dual independent configurations?
No - the SI82E99BBC-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 support independent VIA/VIB control. Its pinout and truth table confirm PWM-driven complementary outputs with built-in dead time and overlap protection, optimized for half-bridge topologies.
How is dead time programmed on the SI82E99BBC-IS1R?
Dead time on the SI82E99BBC-IS1R is set by connecting an external resistor (RDT) between the DT pin and GNDI. Values from 10 kΩ to 110 kΩ yield typical dead times of 18 ns to 200 ns, calculated as tDT = 1.73 × RDT + 5.74 (RDT in kΩ). Connecting DT directly to VDDI disables dead time insertion and overlap protection, forcing dual-driver behavior - though this is not the intended use case for SI82E99BBC-IS1R.
What UVLO thresholds are implemented in the SI82E99BBC-IS1R?
The SI82E99BBC-IS1R offers factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, and matching thresholds on VDDA and VDDB. These are fixed per device variant and cannot be adjusted externally. The hysteresis is typically 0.5 V, ensuring clean entry/exit from lockout during supply ramp-up or brown-out conditions - critical for preventing erratic switching in automotive and industrial power systems.
Is the SI82E99BBC-IS1R qualified for automotive applications?
Yes - the SI82E99BBC-IS1R is AEC-Q100 Grade 1 qualified (–40 to 125 °C ambient), manufactured using automotive-specific process flows, and certified for 2 MOPP medical isolation (IEC 60601-1). It is explicitly listed in Skyworks' automotive-grade OPN offerings and approved for use in EV traction inverters, battery management systems, and onboard chargers where functional safety and long-term reliability are mandatory.
