Overview
The TDF8599CTH/N1,112 is a dual Bridge-Tied Load (BTL) Class-D car audio amplifier from NXP Semiconductors. It features an NDMOST-NDMOST output stage based on SOI BCDMOS technology. The device operates in I2C-bus or non-I2C-bus modes with supply voltages ranging from 8 V to 24 V. It supports two 4 Ω/2 Ω capable BTL channels or one 1 Ω capable BTL channel. Key specifications include a typical quiescent current of 90 mA and up to 43 W output power per channel at 2 Ω. Integrated protections include thermal foldback, overcurrent, load dump, and DC offset detection.
Feature Summary
- High-efficiency Class-D architecture with low quiescent current
- Dual BTL channels configurable for stereo or parallel high-current drive
- Comprehensive protection including thermal foldback, overcurrent, and load dump
- Flexible control via I2C-bus or hardware pins with extensive diagnostic feedback
Applications
- Car audio systems
- Automotive infotainment amplifiers
Procurement Notes
Verify the specific ordering suffix 'N1,112' against official NXP documentation to confirm packaging type and RoHS compliance status. Ensure the selected variant matches the required heat dissipation and interface configuration for the target automotive application design.
Selection Notes
Select this component for applications requiring high efficiency and robust protection in automotive environments. Consider the I2C-bus mode for advanced diagnostics and address selection if system integration requires digital control. Verify that the external filter components and heat sink design align with the specified operating voltage and power output requirements.
Part Context
This part belongs to the TDF8599 series of I2C-bus controlled class-D power amplifiers. The series is designed for automotive use, offering scalable power solutions with integrated load diagnostics. The TDF8599B datasheet provides the technical foundation for these devices, detailing their operation in both master and slave oscillator configurations.
Replacement Considerations
Check for TDF8599ATH/N2C as a potential alternative within the same product family. Verify pin compatibility and electrical specifications before substitution.
