TDA8563AQ/N2C,112

Overview

The TDA8563AQ is a Class-B stereo BTL car radio power amplifier in a 13-lead DBS13P package. It delivers up to 40 W into 2 Ω or 25 W into 4 Ω at 14.4 V with 10% THD. Operating voltage ranges from 6.0 V to 18 V, with a typical quiescent current of 115 mA and standby current of 0.1 mA. The fixed closed-loop gain is 26 dB. It features diagnostic outputs for distortion, short-circuit, and thermal detection, along with load dump protection up to 45 V and reverse polarity safety.

Feature Summary

• Integrated diagnostic facility providing open-collector output for dynamic distortion, short-circuit, and temperature detection
• Robust protection mechanisms including load dump, reverse polarity, thermal shutdown, and short-circuit safety to ground, supply, and across the load
• Flexible mode select switch enabling operating, mute, and standby states with low input current requirements
• Low output offset voltage and high ripple rejection ensuring stable audio performance in automotive environments

Applications

• Car radio power amplification
• Automotive audio systems
• BTL speaker drive circuits

Procurement Notes

Verify the component matches the Philips Semiconductors (NXP) product specification dated February 21, 2001. Confirm the package is DBS13P (SOT141-6) with 13 leads. Ensure the part number corresponds to the TDA8563AQ variant. Check datasheet status as a final production specification. Validate that ordering suffixes do not alter functional parameters unless explicitly documented by the manufacturer.

Selection Notes

Select this device for applications requiring high output power in a single-chip solution for automotive radios. It supports both 2 Ω and 4 Ω loads. The fixed 26 dB gain simplifies circuit design. Consider the diagnostic pin for system monitoring. Ensure thermal management meets the junction-to-case resistance requirements. Verify compatibility with 12 V automotive electrical systems within the 6 V to 18 V operating range.

Part Context

The TDA8563AQ belongs to the TDA856x series of BTL car radio power amplifiers developed by Philips Semiconductors. It is designed to replace older discrete solutions or simpler amplifier ICs in vehicle audio systems. The family focuses on high efficiency and integrated protection features suitable for harsh automotive electrical environments. It serves as a direct replacement for legacy designs requiring stereo BTL amplification with diagnostic capabilities.
