Product details
Overview
SI82396AD-IS from Skyworks Solutions is a dual-channel isolated gate driver IC designed for high-side/low-side MOSFET and IGBT control in power converters. 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 enhanced UVLO with no status pin. It is used in industrial inverters, motor drives, and isolated DC-DC supplies.
For engineers reviewing the SI82396AD-IS datasheet, SI82396AD-IS pinout, SI82396AD-IS application, or SI82396AD-IS equivalent, this page provides verified technical context, safety-critical timing parameters (30 ns propagation delay, 100 kV/µs CMTI), dead-time programmability (10–200 ns), fail-safe low-default outputs, and automotive-grade compatibility (AEC-Q100 qualified).
Technical Context
The SI82396AD-IS implements RF-based silicon isolation with on/off keying modulation across a reinforced barrier, enabling robust noise immunity without optical degradation. Its dual independent inputs (VIA/VIB) drive two isolated output channels with separate VDDA/VDDB supplies - each monitored by dedicated UVLO circuits that force corresponding outputs low upon undervoltage detection.
This variant belongs to the Si8239x "UVLO Status" subgroup (Table 2.2): it provides enhanced UVLO (output fault detection) but omits the RDY status feedback pin. Startup includes a safe 1 ms delayed initialization, and EN (active-high) enables system-level shutdown with guaranteed low-output behavior during disable or VDDI power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS withstand voltage - meets reinforced insulation requirements per IEC62368-1 and VDE 0884-10. |
| Peak Output Current | 4.0 A - sufficient to directly drive high-gate-charge IGBTs and GaN FETs without external buffers. |
| Propagation Delay | 30 ns - enables precise timing control in >1 MHz switching topologies like LLC resonant converters. |
| CMTI | 100 kV/µs - ensures reliable operation in noisy high-dV/dt environments such as motor drives and traction inverters. |
| Input Supply Range | 2.5 V–5.5 V VDDI - compatible with modern low-voltage microcontrollers and FPGA I/O domains. |
| Dead Time Range | 10–200 ns - programmable via external resistor to prevent shoot-through in half-bridge configurations. |
| Operating Temperature | –40 °C to +125 °C - supports industrial and automotive under-hood applications without derating. |
Pinout & Package
SI82396AD-IS is housed in a RoHS-compliant SOIC-16 wide-body package (7.5 mm body width, 10.3 mm length) with creepage/clearance optimized for reinforced insulation. Pin spacing complies with IPC-7351B standard for 1.27 mm pitch.
| 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 enable; forces both outputs low when deasserted, independent of input states. |
| VDDI | Input-side supply | 2.5 V–5.5 V power for logic and isolation transmitter; UVLO threshold is 2.3 V (typ). |
| GNDI | Input-side ground | Reference for VIA, VIB, EN, and VDDI; galvanically isolated from power-side grounds. |
| VDDA | Output A supply | 10 V–24 V supply for high-side driver channel; monitored by independent UVLO (6 V threshold). |
| VOA | Output A driver | 4 A capable push-pull output; defaults low during VDDI UVLO or VDDA undervoltage. |
| GND1 | Power-side ground A | Return path for VDDA and VOA; isolated from GNDI and GND2. |
| VDDB | Output B supply | 10 V–24 V supply for low-side driver channel; monitored by independent UVLO (6 V threshold). |
| VOB | Output B driver | 4 A capable push-pull output; defaults low during VDDI UVLO or VDDB undervoltage. |
| GND2 | Power-side ground B | Return path for VDDB and VOB; isolated from GNDI and GND1. |
| NC | No connect | Pins 13, 14, 15, and 16 are internally unused and must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe default-low outputs | Both VOA and VOB drive low when VDDI is unpowered or in UVLO - prevents unintended power device turn-on during brownout. |
| Enhanced UVLO monitoring | Dual independent UVLO circuits (VDDA & VDDB) detect undervoltage and force respective outputs low - critical for transformer-coupled topologies to avoid flux walk. |
| Programmable dead time | 10–200 ns range set by single external resistor - eliminates need for external timing components in half-bridge gate drive. |
| Safe delayed startup | 1 ms typical tSTARTUP_SAFE - ensures monotonic output behavior during power-up, simplifying system initialization sequencing. |
| High CMTI immunity | 100 kV/µs common-mode transient immunity - maintains signal integrity in high-noise motor control and inverter applications. |

FAQ
What is the UVLO threshold for the input supply (VDDI) of the SI82396AD-IS?
The SI82396AD-IS has a VDDI UVLO threshold of 2.3 V (typical), with hysteresis of 100 mV. When VDDI falls below 2.3 V, the device enters UVLO and forces both VOA and VOB low. The SI82396AD-IS exits UVLO when VDDI rises above 2.4 V. This behavior ensures clean, predictable startup and shutdown sequences in systems with unstable input rails.
Does the SI82396AD-IS support programmable dead time, and how is it configured?
Yes, the SI82396AD-IS supports programmable dead time in the 10–200 ns range. It is configured using a single external resistor connected between the DT pin and GNDI. The exact value is selected from the datasheet's DT resistor table - for example, a 10 kΩ resistor yields ~50 ns dead time. No additional capacitors or logic are required, simplifying PCB layout and reducing BOM count.
Is the SI82396AD-IS pin-compatible with other Si8239x variants in the same package?
Yes, the SI82396AD-IS is pin-compatible with all Si8239x devices in the SOIC-16 wide-body package, including SI82396BD-IS and SI82396CD-IS. All share identical pin assignments, electrical interface, and mechanical footprint. Only the UVLO threshold differs - making them drop-in replacements when adjusting for different gate-drive rail voltages.
What safety certifications does the SI82396AD-IS hold?
The SI82396AD-IS is certified to UL 1577 (5000 Vrms, 1 min), VDE 0884-10 (basic insulation), and IEC62368-1/IEC60950-1 (reinforced insulation). It also meets AEC-Q100 Grade 1 qualification for automotive use. These approvals validate its suitability for safety-critical applications including industrial power supplies and EV on-board chargers.
How does the SI82396AD-IS behave during VDDI power loss?
When VDDI is removed or drops into UVLO, the SI82396AD-IS immediately forces both VOA and VOB low - a fail-safe condition that prevents unintended turn-on of power switches. This behavior is guaranteed regardless of VDDA or VDDB state. The SI82396AD-IS resumes normal operation only after VDDI exceeds 2.4 V and the 1 ms safe startup timer completes.
