NXP Semiconductors TDA8589J
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.| Part No. | TDA8589J |

FEATURES
Amplifiers● I2C-bus control
● Can drive a 2 Ω load with a battery voltage of up to 16 V and a 4 Ω 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 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.
APPLICATIONS
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 digi...
