NXP Semiconductors TDA8594
The TDA8594 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. It contains four independent amplifiers in BTL configuration. The status of each amplifier (output offset, load or no load, short-circuit or speaker incorrectly connected) can be read separately.| Part No. | TDA8594 |

FEATURES AND BENEFITS
2.1 General● Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant)
● Three hardware-programmable I2C-bus addresses
● Drives 4 or 2 loads
● Speaker fault detection
● Independent short-circuit protection per channel
● Loss of ground and open VP safe (with 200 m series impedance and a supply decoupling capacitor of 2200 F maximum)
● All outputs short-circuit proof to ground, supply voltage and across the load
● All pins short-circuit proof to ground
● Temperature-controlled gain reduction to prevent audio holes at high junction temperatures
● Low battery voltage detection
● Offset detection
● This part has been qualified in accordance with AEC-Q100 2.2 I2C-bus mode
● DC load detection: open-circuit, short-circuit and load present
● AC load (tweeter) detection
● During start-up, can detect which load is connected so the appropriate gain can be selected without audio pop
● Independently selectable soft mute of front channels (channel 1...
