TDA1562Q/N3/S10C,1

Overview

The TDA1562Q/N3/S10C,1 is a monolithic integrated circuit featuring a mono class-H Bridge-Tied Load (BTL) power amplifier. It delivers up to 70 W output power into a 4 Ω load at 14.4 V with 10% THD. The device operates from a single supply voltage ranging from 8 V to 18 V and includes built-in diagnostic facilities for dynamic distortion, short-circuit, open load, and temperature protection. It utilizes a 17-lead DBS17P plastic DIL-bent-SIL package.

Feature Summary

• Class-H high efficiency operation with lift-supply capability for increased power output
• Integrated diagnostic interface providing status on clipping, shorts, and thermal conditions
• Flexible control modes including standby, mute, and fast mute via dedicated pins
• Comprehensive protection against short circuits, overtemperature, and load dump events

Applications

• Car audio systems such as car radios and boosters
• Mains fed midi/mini audio combinations
• TV sound applications

Procurement Notes

Verify the specific ordering suffix S10C corresponds to the lead length variant defined in the official documentation. Confirm the component status as preliminary or production data before final design integration. Ensure compatibility with the specified 17-lead DBS17P package dimensions for PCB layout. Check for any updates to the datasheet that may supersede the 2003 February 12 version.

Selection Notes

Select this component for applications requiring high output power from a single low supply voltage. Consider the class-H architecture for reduced power dissipation during music signals compared to class-B amplifiers. Evaluate the need for external lift capacitors to enable the high-power mode. Ensure the thermal management design accounts for the junction-to-case thermal resistance.

Part Context

This part belongs to the TDA1562 family of high-efficiency power amplifiers developed by Philips Semiconductors. The family includes variants like TDA1562ST and TDA1562SD, which share similar electrical characteristics but differ in package types. The TDA1562 series is designed specifically for automotive and mains-fed audio applications requiring robust diagnostics and high power density.

Replacement Considerations

Direct substitutes include TDA1562ST and TDA1562SD, provided the package form factor matches the application requirements. Verify pinout compatibility and electrical specifications before substitution.
