TDA8589AJ/N3,112

Overview

The TDA8589AJ/N3,112 is an I2C-bus controlled quad power amplifier and multiple voltage regulator. It features four BTL amplifiers delivering up to 45 W per channel into a 4 Ω load at 14.4 V. The device includes five voltage regulators, two power switches, and comprehensive diagnostic capabilities via the I2C interface. Operating supply voltage ranges from 8 V to 18 V. It supports DC and AC load detection, thermal protection, and low battery detection.

Feature Summary

I2C-bus controlled quad BTL audio power amplifier with independent channel diagnostics
Multiple voltage regulator section with selectable output voltages and backup functionality
Comprehensive protection including short-circuit, thermal, and load-dump safeguards
DC and AC load detection for speaker integrity verification

Applications

Boost amplifier and voltage regulator for car radios
Power amplifier and voltage regulator for CD/MD players

Procurement Notes

Verify the specific suffix N3,112 against the datasheet ordering information to confirm Regulator 2 and Regulator 3 fixed output voltages (5 V and 3.3 V respectively). Ensure the DBS37P package type matches the target PCB footprint. Confirm that the I2C address and instruction byte configurations align with the microcontroller implementation.

Selection Notes

Select this component when a combined solution for high-power audio amplification and system voltage regulation is required in automotive environments. The TDA8589AJ variant provides specific fixed regulator outputs suitable for 3.3 V digital logic supplies. Consider the I2C control overhead and the need for external capacitors for SVR, ACGND, and backup functions during the design phase.

Part Context

The TDA8589 series integrates a complementary quad audio power amplifier using BCDMOS technology with a multi-output voltage regulator. The TDA8589AJ variant specifically fixes Regulator 2 at 5 V and Regulator 3 at 3.3 V. It is designed for automotive applications requiring robust power management and audio performance in a single integrated circuit.
