GENERAL DESCRIPTION
Ampli
ers
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
I

C-busallowsdiagnosticinformation ofeachamplifier 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).
Voltage regulators
The TDA8589 has a multiple output voltage regulator with
two power switches.
The voltage regulator contains the following:
Four switchable regulators and one permanently active
regulator (microcontroller supply)
Two power switches with loss-of-ground protection
A reset output that can be used to communicate with a
microcontroller.
The quiescent current has a very low level of 150 A with
only regulator 2 active.
