TDA8588J; TDA8588xJ
General description
Amplifiers
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 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 TDA8588 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 uA with only regulator 2 active.
Features
Amplifiers
- I2C-bus control
- Can drive a 2 Ohm load with a battery voltage of up to 16 V and a 4 Ohm 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 pct. or 4 pct.
- Programmable thermal protection pre-warning
- Independent short-circuit protection per channel
- Low gain line driver mode (20 dB)
- Loss-of-ground and open VP safe
- All outputs protected from short-circuit to ground, to VP or across the load
- All pins protected from short-circuit to ground
- Soft thermal-clipping to prevent audio holes
- Low battery detection.
Voltage regulators
GENERAL- I2C-bus control
- Good stability for any regulator 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.
- 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.
