TDF8599ATH/N2,518

Overview

The TDF8599ATH/N2,518 is a dual Bridge-Tied Load (BTL) Class-D car audio amplifier from NXP Semiconductors. It utilizes an NDMOST-NDMOST output stage based on SOI BCDMOS technology for high efficiency and low power dissipation. The device supports I2C-bus or non-I2C-bus operation modes. Key electrical parameters include a supply voltage range of 8 V to 35 V. Output power reaches 135 W at 4 Ω and 250 W at 2 Ω under specific conditions. It features differential inputs, clip detect, and independent short circuit protection for each channel.

Feature Summary

• Dual BTL channels with configurable parallel mode for high current drive capability
• Integrated load diagnostics including DC/AC load detection and thermal pre-warning in I2C-bus mode
• Advanced protection suite covering thermal foldback, overtemperature, overcurrent, window protection, and DC offset
• Flexible clocking options with spread spectrum, frequency hopping, and phase staggering capabilities

Applications

• Car audio systems
• Connected radio infotainment
• Automotive amplifiers

Procurement Notes
