TDF8599TH/N2,518

Overview

The TDF8599TH/N2,518 is a dual Bridge-Tied Load (BTL) car audio amplifier from NXP Semiconductors. It utilizes an NDMOST-NDMOST output stage based on SOI BCDMOS technology to deliver high efficiency in a Class-D configuration. The device provides 135 W of power into a 4 Ohm load and 250 W into a 2 Ohm load. It operates within a supply voltage range of 8 V to 35 V. Key electrical specifications include a maximum output current of 18 A and a common-mode rejection ratio of 80 dB. The component functions effectively with smaller heat sinks compared to standard Class-AB amplifiers due to low power dissipation.

Feature Summary

• Dual Bridge-Tied Load (BTL) architecture for high-power stereo audio applications
• SOI BCDMOS technology enabling high efficiency and reduced thermal requirements
• Integrated I2C-bus control for flexible system management
• Built-in load diagnostics and protection mechanisms including short-circuit and thermal safeguards

Applications

• Car audio amplifiers
• Infotainment systems
• Connected radio designs

Procurement Notes

Verify the specific suffix and package variant when sourcing, as availability may vary by region. Confirm RoHS compliance status for the specific batch, as older revisions may differ. Check the lifecycle status carefully, as some variants are marked as last-sale or obsolete. Ensure the ordering part number matches the required packaging format such as tube or reel. Cross-reference datasheet revision dates to confirm feature consistency.

Selection Notes

Select this component for automotive audio designs requiring high power density and efficient thermal management. The I2C interface allows for precise gain and mode configuration via microcontroller integration. Consider the 36-pin HSOP package dimensions for PCB layout constraints. Evaluate the 8 V to 35 V operating range against the vehicle's power supply stability. Ensure the application benefits from the integrated diagnostics for system reliability.
