Product details
Overview
SI82E29AGC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with 6 A peak output current, universal configuration (independent VIA/VIB inputs), and disable (DIS) control logic. It delivers <5 ns channel-to-channel skew, 200 kV/µs CMTI, and 6 kVRMS reinforced isolation for driving SiC/GaN MOSFETs and IGBTs in half-bridge power stages.
For engineers reviewing the SI82E29AGC-IS1R datasheet, SI82E29AGC-IS1R pinout, SI82E29AGC-IS1R application, or SI82E29AGC-IS1R equivalent, this page provides verified functional identity, validated SOIC-16 narrow-body package mapping, confirmed UVLO thresholds (4 V / 8 V / 12 V / 15 V), exact dead-time programmability via DT pin, and two field-validated alternative parts with documented technical and application differences.
Technical Context
The SI82E29AGC-IS1R implements capacitive silicon-dioxide isolation with differential RF-modulated OOK signaling, enabling precise timing control and fault tolerance between input and output domains. Its universal input architecture accepts independent non-inverting logic signals on VIA and VIB, with DIS-driven unconditional low-state forcing on both outputs.
It supports voltage-mode drive with external gate resistors, features integrated shutdown clamps for unpowered operation, and includes independent UVLO monitoring on VDDI, VDDA, and VDDB rails. Thermal shutdown triggers at TSD+ = 150 °C with hysteresis reset at TSD– = 135 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs SI8239AD-D-IS1R | Enable (EN) input instead of DIS; identical SOIC-16NB package and 6 A drive | Requires active-high enable logic instead of active-high disable; truth table behavior differs during fault handling | Select when system controller asserts enable during normal operation and deasserts only on fault |
| TI UCC5390SCDWR | 3.3–15 V input range (narrower than SI82E29AGC-IS1R's 3–20 V); 4 A peak output (vs. 6 A) | Limited to lower-Qg devices; lacks programmable dead time - fixed internal delay only | Choose for cost-sensitive 3.3 V/5 V systems where 4 A drive suffices and dead time flexibility is not required |
Compared with SI82E29AGC-IS1R, SI8239AD-D-IS1R offers identical performance but inverted control polarity, while UCC5390SCDWR trades drive strength and configurability for lower cost and smaller footprint in less demanding applications.

FAQ
What is the isolation rating and safety certification status of the SI82E29AGC-IS1R?
The SI82E29AGC-IS1R provides 6 kVRMS isolation for one minute and is certified to UL 1577, VDE 60747-17 (reinforced insulation), CSA 62368-1, and IEC 60601-1 (2 MOPP). It meets reinforced insulation requirements for functional safety in industrial and automotive systems, with a 1500 VRMS working voltage rating confirmed in the datasheet.
Does the SI82E29AGC-IS1R support both high-side and low-side gate driving in a single package?
Yes, the SI82E29AGC-IS1R supports both configurations. In its universal mode (VIA/VIB inputs), it drives two independent switches-enabling high-side/low-side, dual low-side, or dual high-side topologies. Its isolated GNDA and GNDB references allow true floating operation for high-side drive without bootstrap complexity.
How is dead time programmed on the SI82E29AGC-IS1R, and what is the adjustment range?
Dead time on the SI82E29AGC-IS1R is set by connecting a resistor (RDT) from the DT pin to GNDI. With RDT = 10–110 kΩ, typical dead time ranges from 17.3 ns to 190 ns per Equation 1 in the datasheet. Connecting DT to VDDI disables dead time and overlap protection, converting the device to a pure dual driver.
What UVLO thresholds are implemented in the SI82E29AGC-IS1R, and how are they selected?
The SI82E29AGC-IS1R offers factory-configured UVLO thresholds of 4 V, 8 V, 12 V, or 15 V on VDDI, VDDA, and VDDB rails. The specific threshold is fixed per orderable part number and cannot be adjusted externally. This selection ensures reliable startup/shutdown behavior matched to the gate driver supply rail's regulation tolerance.
Is the SI82E29AGC-IS1R qualified for automotive applications, and which AEC-Q100 grade does it meet?
Yes, the SI82E29AGC-IS1R is AEC-Q100 qualified Grade 1 (–40 °C to +125 °C ambient), with manufacturing performed in automotive-specific flows. It supports automotive applications including onboard chargers, DC-DC converters, and auxiliary inverters where long-term reliability and zero-defect robustness are mandatory.
