Product details
Overview
SI82396CB-IS1R from Skyworks Solutions is a dual-channel isolated gate driver IC designed for high-side/low-side MOSFET/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 with status feedback. It is used in solar inverters and traction inverters requiring robust isolation and fail-safe startup.
For engineers reviewing the SI82396CB-IS1R datasheet, SI82396CB-IS1R pinout, SI82396CB-IS1R application, or SI82396CB-IS1R equivalent, key selection criteria include its 12 V output UVLO threshold, SOIC-16 narrow-body package, independent VIA/VIB inputs, EN pin safety control, and absence of UVLO status pin - critical for isolated half-bridge gate drive integrity in automotive and industrial systems.
Technical Context
The SI82396CB-IS1R implements RF-based silicon isolation with on/off keying modulation, 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 each channel includes dedicated undervoltage lockout monitoring for VDDA and VDDB.
It features fail-safe operation: outputs default low when VDDI is unpowered, and both VOA and VOB are actively driven low during UVLO events. The device lacks an RDY pin and UVLO status pin, distinguishing it from Si82390/1/3 variants, and uses fixed 10–200 ns dead-time programming without deglitch option.

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-IS1R | 8 V output UVLO threshold instead of 12 V; otherwise identical pinout, package, and feature set. | Suitable where lower UVLO threshold aligns with 12 V auxiliary rail tolerances or legacy system requirements. | Select Si82396BD-IS1R when system-level validation confirms 8 V UVLO provides adequate margin against VDDA/VDDB droop during transients. |
| Si82396AD-IS1R | 6 V output UVLO threshold; same SOIC-16 NB package and functional configuration. | Preferred in designs using 12 V supplies with tight regulation or where earlier fault detection is prioritized over noise immunity. | Choose Si82396AD-IS1R only if system-level testing verifies no false triggering occurs under normal load transients on VDDA/VDDB rails. |
Compared with Si82396BD-IS1R and Si82396AD-IS1R, the SI82396CB-IS1R provides the highest UVLO threshold (12 V), offering greatest immunity to supply droop-induced false shutdowns in high-noise inverter and motor drive applications - making it optimal for 24 V auxiliary rail systems where robustness outweighs early fault detection.

FAQ
What is the UVLO threshold for SI82396CB-IS1R, and how does it affect gate drive behavior?
The SI82396CB-IS1R has a 12 V output UVLO threshold on both VDDA and VDDB supplies. When either supply falls below 12 V, the corresponding output (VOA or VOB) is actively driven low to prevent partial turn-on of power devices. This behavior is independent per channel and ensures safe operation during brownout conditions without requiring external monitoring circuitry. The SI82396CB-IS1R does not provide UVLO status feedback to the controller.
Does SI82396CB-IS1R support programmable dead time, and what are the available settings?
Yes, SI82396CB-IS1R supports internal programmable dead time with a fixed range of 10–200 ns. This setting is factory-configured and cannot be adjusted externally via pins or registers. The dead time is inserted between complementary VOA and VOB transitions to prevent shoot-through in half-bridge configurations, eliminating the need for external RC networks or digital delay elements in the gate drive path.
What package type and footprint does SI82396CB-IS1R use, and is it RoHS-compliant?
SI82396CB-IS1R uses a SOIC-16 narrow-body package (7.5 mm width) with 1.27 mm pitch, RoHS-compliant and qualified for 260 °C peak reflow per JEDEC J-STD-020. Its layout supports 8.0 mm creepage and clearance, meeting reinforced insulation requirements for industrial and automotive applications. Pin 1 is marked with a dot, and pins 15–16 are no-connect.
How does the EN pin function on SI82396CB-IS1R, and what is its recommended interface?
The EN pin on SI82396CB-IS1R is an active-high enable input that unconditionally forces both VOA and VOB low when pulled low, overriding all input states. It must be pulled down to GNDI via a 100 kΩ resistor when not actively driven. The EN pin has no effect if VDDI is below its UVLO threshold, and device restart occurs within tRESTART after EN returns high. This provides hardware-level safety interlock capability.
Is SI82396CB-IS1R qualified for automotive applications, and what certifications does it hold?
Yes, SI82396CB-IS1R is available in automotive-grade variant SI82396CB-AS1R, qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C), with AIAG-compliant PPAP documentation, IMDS/CAMDS listings, and full automotive process flow manufacturing. The industrial version SI82396CB-IS1R shares identical electrical parameters and construction but is built using industrial-grade flows and is certified to UL 1577, VDE 0884-10, and IEC62368-1 for reinforced insulation.
