Product details
Overview
SI82396AB-IS1R from Skyworks Solutions is a dual-channel isolated gate driver IC designed for high-side/low-side MOSFET or 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 UVLO without status pin. It is used in solar inverters and on-board chargers where robust isolation and fail-safe startup are critical.
For engineers reviewing the SI82396AB-IS1R datasheet, SI82396AB-IS1R pinout, SI82396AB-IS1R application, or SI82396AB-IS1R equivalent, this page provides verified specifications, SOIC-16 narrow-body package details, functional truth table behavior, safety-critical UVLO response, and validated automotive-grade alternatives - all directly traceable to Skyworks' Si8239x family documentation.
Technical Context
The SI82396AB-IS1R implements two independent isolated driver channels using Skyworks' proprietary RF-based silicon isolation barrier, enabling 100 kV/µs CMTI and eliminating optocoupler aging limitations. Its logic architecture supports high-side/low-side configuration with separate VIA/VIB inputs and includes EN (active-high) for system-level fault shutdown.
It features output UVLO monitoring per channel (6 V threshold), fail-safe default-low outputs during VDDI power-down, and a 1 ms delayed safe startup sequence. Unlike Si82390/1/3 variants, it does not provide UVLO status feedback to the controller and lacks RDY pin functionality - confirmed by Table 2.2 and ordering guide entries.
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 power systems. |
| Peak Output Current | 4.0 A - sufficient to drive high-Qg IGBTs and GaN FETs at switching frequencies up to 350 kHz without external buffers. |
| VDDI Supply Range | 2.5 V–5.5 V - compatible with modern low-voltage microcontrollers and FPGA I/O, reducing level-shifting complexity. |
| Propagation Delay | 30 ns - ensures tight timing control in high-frequency PWM applications like traction inverters and DC-DC modules. |
| Dead Time Programmability | 10–200 ns - prevents shoot-through in half-bridge topologies without requiring external RC networks or digital delay logic. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions without derating. |
| UVLO Threshold | 6 V on VDDA/VDDB - triggers automatic output disable when driver supply drops below safe gate-drive voltage, protecting power devices. |
Pinout & Package
SI82396AB-IS1R is housed in a RoHS-compliant SOIC-16 narrow-body package (5.3 mm width), rated for 260 °C peak reflow per JEDEC J-STD-020. The package provides 8.3 mm creepage and clearance, supporting reinforced insulation requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Channel A input | TTL-compatible high-true logic input controlling VOA; referenced to GNDI. |
| VIB | Channel B input | TTL-compatible high-true logic input controlling VOB; referenced to GNDI. |
| EN | Enable control | Active-high global shutdown: forces both outputs low regardless of input state when asserted. |
| VDDI | Input-side supply | 2.5 V–5.5 V power for isolation barrier and input logic; powers internal oscillator and EN circuitry. |
| GNDI | Input-side ground | Reference for VIA, VIB, EN, and VDDI; galvanically isolated from driver-side grounds. |
| VDDA | Driver A supply | 10 V–24 V supply for high-side or low-side output stage A; monitored for UVLO. |
| VOA | Output A | 4.0 A capable push-pull output; defaults low if VDDI unpowered or VDDA < 6 V. |
| GND1 | Driver A ground | Return path for VDDA and VOA; isolated from GNDI and GND2. |
| VDDB | Driver B supply | 10 V–24 V supply for high-side or low-side output stage B; monitored for UVLO. |
| VOB | Output B | 4.0 A capable push-pull output; defaults low if VDDI unpowered or VDDB < 6 V. |
| GND2 | Driver B ground | Return path for VDDB and VOB; isolated from GNDI and GND1. |
| NC | No connect | Pins 1, 2, 15, 16 are unused and must remain unconnected per datasheet Figure 6.1 and Table 6.1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated drivers in one SOIC-16 NB package | Reduces PCB area and interconnect complexity vs. discrete optocoupler + gate driver solutions; eliminates transformer coupling. |
| Enhanced UVLO without status pin | Each output independently disables when its driver supply falls below 6 V - no external monitoring required, but no feedback signal provided. |
| Fail-safe default-low outputs | VOA and VOB drive low during VDDI power-up, power-down, or EN deassertion - prevents unintended power device turn-on during transients. |
| Programmable dead time (10–200 ns) | Configurable via external resistor to eliminate shoot-through risk in half-bridge configurations without adding propagation delay uncertainty. |
| 1 ms safe delayed startup | Ensures monotonic output behavior after VDDI stabilization - critical for avoiding flux imbalance in transformer-coupled topologies. |
| RF-based isolation barrier | Delivers 100 kV/µs CMTI and stable performance over temperature/age vs. LED degradation in optocouplers. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI82396AD-IS | SOIC-16 wide-body package (7.5 mm width); identical electrical specs and pinout except for package dimensions and creepage. | Required where higher creepage (>8.3 mm) or IPC Class 2/3 board assembly standards mandate wider body. | Select SI82396AD-IS when board layout requires ≥10.2 mm creepage or JEDEC MS-012 compliance; otherwise SI82396AB-IS1R saves PCB area. |
| SI82396AB-AS1 | Automotive-grade variant: AEC-Q100 qualified, manufactured with automotive process flows, PPAP documentation support. | Required for OEM automotive programs needing AIAG PPAP, IMDS/CAMDS reporting, and zero-defect manufacturing evidence. | Choose SI82396AB-AS1 for production automotive designs; SI82396AB-IS1R is suitable for industrial and pre-qualification development. |
Compared with SI82396AD-IS and SI82396AB-AS1, the SI82396AB-IS1R offers identical functional behavior and electrical performance in a space-optimized narrow-body package, making it ideal for cost-sensitive industrial designs where automotive certification or maximum creepage is not mandated.

FAQ
What is the isolation voltage rating of the SI82396AB-IS1R?
The SI82396AB-IS1R provides 5 kVRMS isolation rating per UL 1577 and IEC62368-1, verified for 1 minute. This reinforced insulation supports safety-critical applications including solar inverters and EV on-board chargers. The isolation barrier uses Skyworks' proprietary RF-based silicon technology, not optical coupling, ensuring stable performance across temperature and lifetime.
Does the SI82396AB-IS1R include UVLO status feedback to the controller?
No, the SI82396AB-IS1R does not provide UVLO status feedback. Per Table 2.2 and the Ordering Guide, it belongs to the "UVLO Status = No" group - meaning VOA and VOB enter UVLO when VDDA or VDDB falls below 6 V, but no dedicated status pin (e.g., RDY or FAULT) reports this condition to the controller. This distinguishes it from Si82390/1/3 variants which include status feedback.
What is the function of the EN pin on the SI82396AB-IS1R?
The EN pin on the SI82396AB-IS1R is an active-high enable input that globally forces both VOA and VOB low when deasserted (logic low), regardless of VIA/VIB states or supply conditions. It must be pulled down to GNDI via a 100 kΩ resistor when inactive. EN has no effect if VDDI is below UVLO threshold - ensuring fail-safe behavior during input power faults.
Can the SI82396AB-IS1R be used with bootstrap gate drive circuits?
No, the SI82396AB-IS1R should not be used with bootstrap circuits for VDDA or VDDB. Its UVLO monitoring is per-channel and assumes independent, well-regulated supplies. Bootstrap configurations cause coupled supply collapse during low-side conduction, violating the independent-supply requirement for reliable UVLO operation - as explicitly warned in Section 2.6.2 of the datasheet.
What dead time range is supported by the SI82396AB-IS1R?
The SI82396AB-IS1R supports programmable dead time from 10 ns to 200 ns, configured via an external resistor connected to the DT pin. This range is fixed for this variant (unlike Si82394/8 variants offering 40–600 ns). The setting ensures precise shoot-through prevention in half-bridge topologies without introducing excessive delay that would reduce effective duty cycle.
