Product details
Overview
SI82396CD-AS3 from Skyworks Solutions is a dual-channel isolated gate driver IC designed for high-side/low-side MOSFET and IGBT control in power converters and motor drives. It delivers 4.0 A peak output current, operates with 2.5 V–5.5 V input supply (VDDI), supports up to 5 kVRMS isolation, and features programmable dead time (10–200 ns) and enhanced output UVLO without status feedback. It is used in solar inverters and traction inverters requiring robust isolation and fail-safe operation.
For engineers reviewing the SI82396CD-AS3 datasheet, SI82396CD-AS3 pinout, SI82396CD-AS3 application, or SI82396CD-AS3 equivalent, key selection criteria include its SOIC-14 wide-body package, 12 V output UVLO threshold, absence of UVLO status pin, lack of deglitch filtering, and compatibility with independent VIA/VIB inputs for high-side/low-side configurations - all critical for isolated half-bridge gate drive design.
Technical Context
The SI82396CD-AS3 implements RF-based on/off keying across a silicon isolation barrier, enabling high CMTI (100 kV/µs) and low propagation delay (30 ns). Its dual-channel architecture supports independent high-side and low-side gate drive with separate VIA and VIB inputs, and includes EN (active-high) for system-level safety shutdown.
It integrates fail-safe logic that forces both outputs low during VDDI power-down or UVLO conditions, and provides programmable dead time to prevent shoot-through in bridge topologies. Unlike Si82390/1/3 variants, it does not feed UVLO status back across the isolation barrier - UVLO detection is local to each output stage only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS withstand voltage - enables reinforced insulation per IEC62368-1 and UL 1577 for mains-connected systems. |

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 |
|---|---|---|---|
| SI82396BD-AS3 | 8 V output UVLO threshold (vs. 12 V); otherwise identical pinout, package, and feature set. | Suitable for systems using lower driver supply rails (e.g., 12 V instead of 15/24 V), where earlier UVLO activation improves margin against supply droop. | Select SI82396BD-AS3 when VDDA/VDDB nominal is ≤13.5 V and tighter UVLO margin is needed; verify gate drive stability at lower VDD. |
| SI82396AD-AS3 | 6 V output UVLO threshold; same SOIC-14 WB package and functional configuration. | Preferred for 10–12 V driver supply designs with aggressive brown-out tolerance, such as auxiliary power modules or low-voltage DC-DC stages. | Choose SI82396AD-AS3 for cost-sensitive industrial applications where 6 V UVLO provides adequate protection without over-spec'ing supply headroom. |
Compared with SI82396BD-AS3 and SI82396AD-AS3, the SI82396CD-AS3 offers the highest output UVLO threshold (12 V), making it optimal for 15 V or 24 V driver supply rails common in high-power inverters - reducing risk of unintended UVLO trips during transient load steps.
