Voltage regulators
GENERAL
I2C-bus control
Good stability with almost any output capacitor value
Five voltage regulators (microcontroller, display,
mechanical digital, mechanical drive and audio)
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
High supply voltage ripple rejection
Low noise for all regulators
Two power switches (antenna switch and amplifier
switch)
Regulator 2 (microcontroller supply) operational during
load-dump and thermal shut-down
Low quiescent current (only regulator 2 is operational)
Reset output (push-pull output stage)
Adjustable reset delay time
Backup functionality.

PROTECTION
If connection to the battery voltage is reversed, all
regulator voltages will be zero
Able to withstand voltages at the output of up to 18 V
(supply line may be short-circuited)
Thermal protection to avoid thermal breakdown
Load-dump protection
Regulator outputs protected from DC short-circuit to
ground or to supply voltage
All regulators protected by foldback current limiting
Power switches protected from loss-of-ground.
APPLICATIONS
Boost amplifier and voltage regulator for car radios and
CD/MD players.
GENERAL DESCRIPTION
Amplifiers
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).
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 µA with
only regulator 2 active.
