FEATURES
Amplifiers
·
I 2 C-bus control
·
Can drive a 2
W
load with a battery voltage of up to 16 V
and a 4
W
load with a battery voltage of up to 18 V
·
DC load detection: open, short and present
P ROTECTION
·
AC load (tweeter) detection

Programmable clip detect 1 % or 3%
·
Programmable thermal protection pre-warning
·
Able to withstand voltages at the output of up to 18 V
(supply line may be short-circuited)
·
Independent short-circuit protection per channel
·
Low gain line driver mode (20 dB)
·
Thermal protection to avoid thermal breakdown
·
Loss-of-ground and open V P safe
·
Load-dump protection
·
All outputs protected from short-circuit to ground, to V P ,
or across the load
·
Regulator outputs protected from DC short-circuit to
ground or to supply voltage
·
All pins protected from short-circuit to ground
·
All regulators protected by foldback current limiting
·
Soft thermal-clipping to prevent audio holes
·
Power switches protected from loss-of-ground.
·
Low battery detection.
Voltage regulators
APPLICATIONS
·
Boost amplifier and voltage regulator for car radios and
CD/MD players.
G ENERAL
·
I 2 C-bus control
·
Good stability with almost any output capacitor value
GENERAL DESCRIPTION
Amplifiers
·
Five voltage regulators (microcontroller, display,
mechanical digital, mechanical drive and audio)
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 2 C-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).
·
Choice of non-adjustable 3.3 or 5 V microcontroller
supply (REG2) versions reducing risk of overvoltage
damage
·
Choice of non-adjustable 3.3 or 5 V digital signal
processor supply (REG3) versions reducing risk of
overvoltage damage
·
Selectable output voltages for regulators 1, 4 and 5
·
Low dropout voltage PNP output stages
Voltage regulators
·
High supply voltage ripple rejection
The TDA8589 has a multiple output voltage regulator with
two power switches.
The voltage regulator contains the following:
·
·
Low noise for all regulators
·
Two power switches (antenna switch and amplifier
switch)
Four switchable regulators and one permanently active
regulator (microcontroller supply)
·
Regulator 2 (microcontroller supply) operational during
load-dump and thermal shut-down
·
Two power switches with loss-of-ground protection
·
Low quiescent current (only regulator 2 is operational)
·
A reset output that can be used to communicate with a
microcontroller.
·
Reset output (push-pull output stage)
·
Adjustable reset delay time
The quiescent current has a very low level of 150 m A with
only regulator 2 active.
·
Backup functionality.
