TDF8544ASD/N2,112

Overview

The TDF8544ASD/N2,112 is a four-channel Class-AB audio power amplifier designed for automotive applications. It delivers up to 50 W per channel into a 4 Ohm load with a supply voltage range of 6 V to 18 V. The device features I2C-bus control for configuration and diagnostics, including start-up checks. Built on an SOI-based BCD process, it ensures robust performance without latch-up risks. The amplifier supports BTL operation and operates reliably during engine start events at low battery voltages.

Feature Summary

I2C-bus controlled four-channel power amplifier
Best efficiency mode reduces power dissipation significantly
Robust SOI-based BCD process prevents latch-up
Operates without audible disturbance during engine start

Applications

Connected car radio systems
Automotive infotainment platforms
Entry-level in-car audio amplifiers
Bluetooth hands-free device integration

Procurement Notes

Verify the exact suffix N2 versus N3 for package type compatibility. Confirm current production status as some variants are discontinued. Check RoHS compliance details for specific regional requirements. Ensure design-in support is available from NXP sales offices.

Selection Notes

Select this part for high-power automotive audio requiring I2C control. Consider the SIP-27 package for through-hole mounting needs. Evaluate thermal management requirements given the 80 W total dissipation capability. Compare against TDF8546 for improved efficiency modes if needed.

Part Context

This component belongs to the TDF8544 series of complementary quad bridge-tied load audio power amplifiers. It is part of NXP's portfolio for scalable connected radio and infotainment solutions. The series targets entry-level to mid-range automotive audio systems with enhanced user interface capabilities.

Replacement Considerations

Official substitutes include TDF8544SD/N3,112 and TDF8544TH/N3,118. Verify pinout and package compatibility before substitution. Check if the replacement variant maintains the same I2C address configuration.
