Product details
Overview
SI82E29ABC-IS1R from Skyworks Solutions is a dual-channel isolated gate driver with high-side/low-side configuration, 6 A peak output current per channel, <5 ns channel-to-channel skew, and 6 kVRMS reinforced isolation. It drives SiC/GaN MOSFETs and IGBTs in half-bridge topologies for onboard chargers and motor inverters.
For engineers reviewing the SI82E29ABC-IS1R datasheet, SI82E29ABC-IS1R pinout, SI82E29ABC-IS1R application, or SI82E29ABC-IS1R equivalent, key selection criteria include dead time programmability via DT pin, CMOS-compatible dual-input control (VIA/VIB), UVLO thresholds at 4/8/12/15 V, and automotive-grade AEC-Q100 qualification.
Technical Context
The SI82E29ABC-IS1R implements capacitive silicon dioxide (SiO₂) isolation with differential RF-modulated OOK signaling, enabling 200 kV/µs CMTI and stable timing across temperature. Its dual-channel architecture supports independent high-side/low-side drive with integrated dead time insertion and overlap protection triggered by simultaneous VIA/VIB high transitions.
It features voltage-mode drive with external gate resistor control, shutdown clamp for unpowered operation, short-circuit clamping to VDDA/B, and independent UVLO monitoring on VDDI, VDDA, and VDDB. The device operates across –40 to +125 °C with 3–20 V logic supply and 5–30 V gate supply ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 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 precise timing alignment between high-side and low-side outputs in half-bridge switching. |
| Peak Output Current | 6 A sourcing/sinking - sufficient to rapidly charge/discharge high-Qg SiC FETs and IGBTs without external buffers. |
| CMTI | >200 kV/µs - prevents false triggering in noisy high-dV/dt power converter environments. |
| UVLO Thresholds | 4 V, 8 V, 12 V, or 15 V - configurable per device variant to match gate driver supply rail stability margins. |
| Dead Time Control | Resistor-programmable (10–110 kΩ on DT pin) - enables precise shoot-through prevention in half-bridge designs. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial motor drive applications. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage-enhanced layout for reinforced isolation. Pinout optimized for high-side/low-side half-bridge control with dedicated input, enable/disable, and dead time programming terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input for channel A | Directly controls VOA output state; high = VOA high (if enabled), low = VOA low. |
| VIB | Non-inverting logic input for channel B | Directly controls VOB output state; high = VOB high (if enabled), low = VOB low. |
| DIS | Active-high disable input | Forces both VOA and VOB low unconditionally when asserted; used for fast fault shutdown. |
| DT | Dead time programming terminal | Resistor-to-GND sets dead time; connection to VDDI disables dead time and overlap protection. |
| VDDI | Logic input supply | 3–20 V CMOS-compatible supply powering internal digital logic and isolation modulator. |
| VDDA / VDDB | Gate driver A/B power supplies | 5–30 V supplies powering output stages; each monitored independently for UVLO. |
| VOA / VOB | High-side/low-side gate drive outputs | Voltage-mode outputs capable of ±6 A peak; include short-circuit clamp and shutdown clamp. |
| GNDI / GNDA / GNDB | Logic input / driver A / driver B grounds | Galvanically isolated ground domains; GNDA/GNDB referenced to respective VDDA/VDDB rails. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS input with deglitch filter option | Rejects sub-100 ns noise spikes while maintaining <30 ns added propagation delay for robust MCU/FPGA interface. |
| Voltage Mode Drive | Enables precise tuning of switching speed, EMI, and gate overshoot via external Rg without changing driver IC. |
| Programmable dead time + overlap protection | Prevents shoot-through in half-bridge by forcing both outputs low on simultaneous VIA/VIB high, then inserting user-defined delay before next transition. |
| Independent UVLO per supply domain | Ensures safe turn-off if VDDI, VDDA, or VDDB drops below threshold - critical for bootstrap supply failure detection. |
| Shutdown clamp (active pull-down) | Provides low-impedance path from VOA/VOB to GNDA/GNDB during unpowered states, preventing parasitic FET turn-on. |

| Onboard Charger (OBC) | Industrial Motor Inverter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated dual-channel gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SIL1225AD-IM | Single-channel, 4 A output, 5 kVRMS isolation, no dead time pin - requires external logic for overlap protection. | Limited to single-leg or discrete half-bridge implementation; not drop-in for dual-channel control. | Select when cost-sensitive, lower-current (<4 A) Si MOSFETs are used and dead time is managed externally. |
| UCC5390SCD | 6 A dual-channel, 5.7 kVRMS isolation, 100 kV/µs CMTI, integrated Miller clamp - lacks programmable dead time pin. | Relies on controller-side dead time generation; no hardware-based overlap protection on simultaneous inputs. | Choose when system-level dead time control is preferred and higher CMTI margin is needed over SI82E29ABC-IS1R. |
Compared with SIL1225AD-IM and UCC5390SCD, SI82E29ABC-IS1R uniquely combines hardware-enforced overlap protection, resistor-programmable dead time, and AEC-Q100 qualification in a single narrow-body SOIC-16 package - simplifying design for automotive OBC and industrial inverter half-bridges.

FAQ
What is the isolation rating and safety certification status of SI82E29ABC-IS1R?
SI82E29ABC-IS1R provides 6 kVRMS isolation for one minute and is certified to UL 1577, VDE 60747-17 (reinforced), CSA 62368-1, and CQC GB4943.1. It supports 1500 VRMS working voltage and meets 2 MOPP requirements per IEC 60601-1 - making it suitable for medical and industrial equipment with stringent safety mandates.
Does SI82E29ABC-IS1R support both high-side/low-side and universal configurations?
SI82E29ABC-IS1R is specifically configured as a high-side/low-side driver with dual non-inverting inputs (VIA/VIB) and a dedicated DIS pin. It does not support universal (PWM-input) mode - that functionality is provided by Si82E39x variants. The pinout and truth table confirm exclusive high-side/low-side operation.
How is dead time programmed on SI82E29ABC-IS1R, and what is the range?
Dead time on SI82E29ABC-IS1R is set by connecting a resistor (RDT) from the DT pin to GNDI. Using Equation tDT = 1.73 × RDT + 5.74 (with RDT in kΩ), dead time ranges from ~23 ns (10 kΩ) to ~196 ns (110 kΩ). Connecting DT to VDDI disables dead time and overlap protection entirely.
What UVLO thresholds are implemented in SI82E29ABC-IS1R?
SI82E29ABC-IS1R features factory-configured UVLO thresholds of 4 V, 8 V, 12 V, and 15 V on VDDI, with hysteresis to prevent chatter during supply ramp-up/down. Independent UVLO monitors also exist on VDDA and VDDB, each with fixed 5.5 V turn-on and 4.5 V turn-off thresholds.
Is SI82E29ABC-IS1R qualified for automotive applications?
Yes, SI82E29ABC-IS1R is AEC-Q100 qualified (Grade 1: –40 °C to +125 °C) and manufactured using automotive-specific process flows. It includes enhanced defectivity controls, extended lifetime testing, and full traceability - meeting requirements for EV onboard chargers, traction inverters, and ADAS power systems.
