The TDA8589 has a complementary quad audio power amplifier that uses BCDMOS technology. It contains four amplifiers configured in Bridge Tied Load(BTL)to drive speakers for front and rear left and right channels. The I2C-bus allows diagnostic information of each amplifier and its speaker to be read separately. Both front and both rear channel amplifiers can be configured independently in line driver mode with a gain of 20 dB (differential output).
The TDA8589 has a multiple output voltage regulator with two power switches.
The voltage regulator contains thefollowing:
Four switchable regulators and one permanently active regulator (microcontroller supply)
Two power switches withloss-of-ground protection
Areset output that can be usedto communicate witha microcontroller.
The quiescent current has a very low level of 150 A with onlyregulator 2 active.
