Product details
Overview
SI82308B-D-IS1R from Skyworks Solutions is a dual-channel isolated gate driver IC with 5 kVRMS input-to-output isolation, 4.0 A peak output current per channel, TTL-compatible inputs with >400 mV hysteresis, and SOIC-16 narrow-body package. It operates across –40°C to +125°C and supports isolated MOSFET/IGBT half-bridge and dual-switch topologies in industrial inverters and motor control systems.
For engineers reviewing the SI82308B-D-IS1R datasheet, SI82308B-D-IS1R pinout, SI82308B-D-IS1R application, or SI82308B-D-IS1R equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade compatibility (AEC-Q100), isolation safety certifications (UL 1577, VDE 60747-17), and real-world design context for high-reliability power conversion designs.
Technical Context
The SI82308B-D-IS1R implements two fully independent isolated driver channels using Skyworks' proprietary silicon RF-based isolation barrier-enabling up to 5 kVRMS withstand voltage and 45 ns propagation delay. Each channel features dedicated UVLO monitoring (5 V threshold) and supports direct connection to separate or common grounds.
It is configured as a dual driver (not HS/LS), with individual VIA/VIB inputs driving VOA/VOB independently-no internal dead-time or overlap protection logic. This enables synchronous or asymmetric switching control in bidirectional converters, isolated DC-DC controllers, and dual-phase motor drives without cross-conduction risk.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8235BD-D-IS1 | Same dual-driver architecture, 4.0 A output, but 8 V UVLO threshold and SOIC-16 narrow-body package | Requires higher input supply (≥8 V) - less suitable for 5 V logic domains without level-shifting | Select when system uses ≥8 V controller rails and needs identical timing/isolation specs |
| ADUM4223BRIZ | 2.5 kVRMS isolation, 4 A output, but uses iCoupler magnetic isolation and has 55 ns max propagation delay | Lacks AEC-Q100 qualification and UL 1577 5 kVRMS certification - limited to industrial, not automotive | Choose for cost-sensitive industrial DC-DC where 2.5 kVRMS meets safety requirements |
Compared with Si8235BD-D-IS1 and ADUM4223BRIZ, SI82308B-D-IS1R provides tighter 45 ns propagation delay, 5 kVRMS isolation for reinforced insulation compliance, and native 5 V UVLO support - making it optimal for space-constrained automotive and high-density industrial power modules requiring highest timing fidelity and safety certification.

FAQ
What is the maximum operating temperature range for the SI82308B-D-IS1R?
The SI82308B-D-IS1R is rated for operation from –40°C to +125°C ambient temperature. This range is validated per AEC-Q100 Grade 1 qualification and applies to both input and output sides. The device maintains full 4.0 A peak output current capability across this range, with propagation delay variation limited to ±5 ns over temperature - critical for thermal-stable PWM timing in motor drives and inverters.
Does the SI82308B-D-IS1R include built-in dead-time control or overlap protection?
No, the SI82308B-D-IS1R does not include programmable dead-time or overlap protection logic. As a dual-driver variant (not HS/LS), it provides fully independent channel control via VIA and VIB inputs. Dead-time must be implemented externally in the controller or gate-drive signal path. This architecture avoids fixed internal delays that could limit flexibility in advanced modulation schemes like phase-shifted full-bridge or resonant LLC control.
What safety certifications apply to the SI82308B-D-IS1R?
The SI82308B-D-IS1R carries UL 1577 recognition for 5000 VRMS one-minute withstand voltage, VDE 60747-17 certification for basic insulation, and CQC GB4943.1 approval for reinforced insulation. It also complies with IEC 62368-1 (reinforced) and IEC 60601-1 (2 MOPP), enabling use in medical, industrial, and grid-tied solar equipment without additional isolation barriers.
Can the SI82308B-D-IS1R drive both high-side and low-side switches in a half-bridge configuration?
Yes - the SI82308B-D-IS1R can drive both switches in a half-bridge, but not as a single integrated HS/LS pair. Its dual-driver architecture requires external coordination: VOA drives the high-side switch (e.g., via bootstrap or isolated supply), and VOB drives the low-side switch referenced to power ground. This approach provides full independence, eliminating shared timing constraints and enabling asymmetric drive strategies for soft-switching topologies.
What is the purpose of the DISABLE pin on the SI82308B-D-IS1R?
The DISABLE pin on the SI82308B-D-IS1R is an active-high global shutdown input. When asserted (VIH ≥ 2.0 V), it forces both VOA and VOB outputs low within tSD ≤ 100 ns, overriding all input states and UVLO conditions. It remains effective only when VDDI is above its 5 V UVLO threshold. This pin enables fast fault response in overcurrent or overtemperature events, supporting functional safety architectures in automotive and industrial systems.
