Product details
Overview
SI82390CB-IS1R 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 output UVLO at 12 V with status feedback and 1 ms safe delayed startup.
For engineers reviewing the SI82390CB-IS1R datasheet, SI82390CB-IS1R pinout, SI82390CB-IS1R application, or SI82390CB-IS1R equivalent, key selection considerations include its SOIC-16 narrow-body package, independent VIA/VIB inputs, programmable dead time absence, deglitch disable, and automotive-grade compatibility via Si82390CB-AS1.
Technical Context
The SI82390CB-IS1R implements RF-based silicon isolation with on/off keying modulation across a semiconductor barrier, enabling robust noise immunity (100 kV/µs CMTI) and eliminating optocoupler aging limitations. Its dual-channel architecture supports independent high-side/low-side drive with fail-safe default-low outputs during VDDI power-down.
It integrates enhanced UVLO monitoring per output stage (12 V threshold), status feedback via RDY pin, active-high EN control, and failsafe behavior when either VDDA or VDDB falls below UVLO-critical for transformer-coupled DC-DC topologies requiring flux balance protection.
Key Specifications

FAQ
What is the isolation voltage rating of the SI82390CB-IS1R?
The SI82390CB-IS1R provides 5 kVRMS isolation rating per UL 1577 and IEC62368-1 standards, supporting reinforced insulation in industrial and automotive power systems. This rating is validated for 1 minute at 5000 Vrms and applies across the full operating temperature range of −40 °C to +125 °C.
Does the SI82390CB-IS1R support programmable dead time?
No, the SI82390CB-IS1R does not support programmable dead time. It belongs to the Si82390/1/3 series, which lacks internal dead-time generation circuitry. For dead-time functionality, consider SI82394xx or SI82398xx variants, which offer 10–200 ns or 40–600 ns adjustable dead time.
What is the purpose of the RDY pin on the SI82390CB-IS1R?
The RDY pin on the SI82390CB-IS1R is an open-drain status indicator that asserts high after the 1 ms safe startup delay and confirms both input-side and driver-side supplies have exited UVLO. It enables the host controller to synchronize gate drive activation with verified power stability.
Can the SI82390CB-IS1R be used with bootstrap gate drive circuits?
No, the SI82390CB-IS1R must not be used with bootstrap circuits. Its enhanced UVLO architecture requires independent VDDA and VDDB supplies; bootstrap configurations cause cross-coupling that prevents proper UVLO coordination and may lead to unsafe operation or device latch-up.
What is the maximum recommended switching frequency for the SI82390CB-IS1R?
The SI82390CB-IS1R supports switching frequencies up to 1 MHz in typical applications, limited by gate charge (QG), external gate resistor (RG), and driver supply voltage (VDDA/VDDB). At 12 V VDDA, 22 Ω RG, and 24 nC QG, thermal modeling shows safe operation up to 350 kHz with 123 mW total dissipation.
