SI82396AB-IS1R

Isolators - Gate Drivers Overview

The SI82396AB-IS1R is a dual-channel isolated gate driver from Skyworks Solutions Inc., utilizing capacitive coupling technology for signal transmission. It operates within a supply voltage range of 3 V to 5.5 V and provides a peak output current of 4 A per channel. The device features a 2.5 kVrms isolation rating and includes a 6 V undervoltage lockout (UVLO) threshold. It is housed in a 16-pin SOIC package and is qualified under the AEC-Q100 standard for automotive applications.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling isolator architecture for high electromagnetic immunity
• Dual-channel configuration with independent high-side and low-side drive capabilities
• Integrated 6 V undervoltage lockout for reliable switching protection
• Automotive-grade qualification compliant with AEC-Q100 standards

Isolators - Gate Drivers Applications

• Automotive powertrain control modules
• Electric vehicle motor drives
• Industrial motor control systems
• High-reliability isolated DC-DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS1R' indicates tape-and-reel packaging, distinct from tube-packaged variants like 'IS1'. Confirm AEC-Q100 certification status for automotive compliance requirements. Ensure input logic levels match TTL specifications. Validate operating temperature range against system thermal constraints.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity is required over optical isolators. The 4 A drive strength suits medium-power MOSFETs and IGBTs. Consider the 16-SOIC footprint for PCB layout compatibility. Compare UVLO thresholds with other Si8239x variants if different gate drive voltages are needed.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of digital isolators. It shares architectural similarities with the SI82396CD-IS but differs in UVLO settings and packaging. The series emphasizes robustness in noisy environments, leveraging Skyworks' proprietary capacitive isolation technology for long-term reliability.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include SI82396AB-IS1 (tube version). For higher UVLO requirements, consider SI82396CD-IS. Verify pinout compatibility before replacing legacy optocouplers or other isolated drivers.
