Philips Semiconductors Product specication
I 2 C-bus controlled 4 45 Watt power
amplier and multiple voltage regulator
TDA8589J; TDA8589xJ
FEATURES
Ampliers
I 2 C-bus control
Can drive a 2 load with a battery voltage of up to 16 V
and a 4 load with a battery voltage of up to 18 V
DC load detection: open, short and present
AC load (tweeter) detection
Programmable clip detect 1 % or 3%
Programmable thermal protection pre-warning
Independent short-circuit protection per channel
Low gain line driver mode (20 dB)
Loss-of-ground and open V P safe
All outputs protected from short-circuit to ground, to V P ,
or across the load
All pins protected from short-circuit to ground
Soft thermal-clipping to prevent audio holes
Low battery detection.
Voltage regulators
G ENERAL
I 2 C-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.
P ROTECTION
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.
