Overview
The TDF8590TH is a high-efficiency Class-D audio power amplifier designed for car audio systems. It delivers 2 × 80 W into 4 Ω in Single-Ended (SE) mode or 160 W into 8 Ω in Bridge-Tied Load (BTL) mode. The device operates with a supply voltage range of ±14 V to ±29 V and features low quiescent current consumption. It includes differential inputs, fixed gains of 26 dB (SE) and 32 dB (BTL), and comprehensive protection circuits such as thermal foldback, overcurrent, and short-circuit protection.
Feature Summary
- Zero dead time switching minimizes distortion and improves efficiency.
- No DC offset induced pop noise during mode transitions ensures silent operation.
- High BTL output power capability up to 160 W into 8 Ω loads.
- Internal oscillator allows synchronization with external clock sources.
Applications
- Car audio systems
- Mono Bridge-Tied Load (BTL) amplifiers
- Dual Single-Ended (SE) stereo amplifiers
Procurement Notes
Verify the exact ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Confirm that the HSOP24 package variant matches your PCB footprint requirements. Ensure compatibility with the required supply voltage range and load impedance before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring high power density and efficiency in automotive environments. Consider the HSOP24 package size and internal heat sink capabilities when designing thermal management solutions. Evaluate the need for external synchronization if multiple Class-D amplifiers are used in the same system to prevent interference.
Part Context
The TDF8590TH belongs to NXP Semiconductors' TDF859X series of D-class amplifiers. It utilizes a dual-channel architecture within a single HSOP24 plastic package. The device integrates advanced protection features and diagnostic outputs, making it suitable for robust automotive audio applications where reliability and performance are critical.
Replacement Considerations
Consult official replacement lists for verified substitutes. Generic cross-references may not match pinouts or electrical characteristics.
FAQ
How is the operating mode selected on the TDF8590TH?
The MODE pin controls the amplifier state: Standby (low current), Mute (silenced output), or Operating (full functionality). An RC network on this pin manages transition timing to prevent pop noise.
What is the function of the DIAG pin?
The DIAG pin provides diagnostic information. It goes LOW when OverCurrent Protection (OCP) or Window Protection (WP) is triggered, indicating faults such as short circuits to the load or supply lines.
