SI8244CB-C-IS1R

Audio Special Purpose Overview

The SI8244CB-C-IS1R is a 2.5 kV isolated gate driver designed for Class D audio amplifier applications. It integrates two isolated drivers in a single package to provide high-side and low-side outputs. The device features a peak output current of 4 A, operates on a supply voltage range of 4.5 V to 5.5 V, and supports up to 2500 Vrms isolation between input and output. It functions within an operating temperature range of -40°C to +125°C.

Audio Special Purpose Feature Summary

• 2.5 kV (2500 Vrms) reinforced isolation
• 4 A peak output current capability
• Integrated precision dead-time generator
• CMOS-based isolation technology with >45 kV/µs common mode transient immunity
• SOIC-16 narrow body package

Audio Special Purpose Applications

• Class D digital audio amplifiers
• High-power audio systems requiring isolated gate driving

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm UVLO thresholds and pinout compatibility. Ensure that the selected variant matches the required undervoltage lockout levels for the target power supply configuration. Cross-reference the package type and thermal characteristics during the procurement phase to ensure compliance with system design constraints.

Audio Special Purpose Selection Notes

Select this component for applications requiring high-side and low-side driving with precise dead-time control to minimize THD. The 4.0 A peak current rating suits high-power audio loads. Consider the 8 V or 10 V UVLO options based on the driver supply voltage availability. Verify that the SOIC-16 narrow body package fits the PCB layout and thermal management requirements.
