GENERAL DESCRIPTION
Amplifiers
·
Good stability for any regulator with almost any output
capacitor value
·
Five voltage regulators (microcontroller, display,
mechanical digital, mechanical drive and audio)
The TDA8588 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
Voltage regulators
·
Low dropout voltage PNP output stages
The TDA8588 has a multiple output voltage regulator with
two power switches.
The voltage regulator contains the following:
·
·
High supply voltage ripple rejection
·
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
·
A reset output that can be used to communicate with a
microcontroller.
·
Low quiescent current (only regulator 2 is operational)
·
Reset output (push-pull output stage)
The quiescent current has a very low level of 150
m
A with
only regulator 2 active.
·
Adjustable reset delay time
·
Backup functionality.
