TDF8599ATH/N2CS

Overview

The TDF8599ATH/N2CS is a dual Bridge-Tied Load (BTL) car audio amplifier utilizing Class-D technology and SOI BCDMOS output stages. It supports I2C-bus or non-I2C operation with selectable addresses. The device delivers up to 135 W per channel into 4 Ω loads and 250 W in single-channel parallel mode into 2 Ω loads, operating within an 8 V to 35 V supply range. Integrated protections include thermal foldback, overcurrent, load dump, and DC offset detection.

Feature Summary

• Dual BTL channels with high-efficiency Class-D architecture
• Configurable I2C-bus or non-I2C control modes
• Integrated diagnostic capabilities for load and fault conditions
• Advanced protection against thermal, current, and voltage anomalies

Applications

• Car audio systems
• Automotive power amplification
• High-efficiency audio processing
