Product Summary
The TDA8594SD is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. The TDA8594SD contains four independent amplifiers in BTL configuration. Through the I2C-bus, diagnosis of temperature warning and clipping level is fully programmable and the information available via two diagnostic pins is selectable. The status of each amplifier (output offset, load or no load, short-circuit or speaker incorrectly connected) can be read separately.
Parametrics
TDA8594SD absolute maximum ratings: (1)reverse supply voltage: -2V; (2)IOSM non-repetitive peak output current: 13 A; (3)IORM repetitive peak output current: 8A; (4)Tj(max)maximum junction temperature: 150 °C; (5)Tstg storage temperature: -55 +150 °C; (6)Tamb ambient temperature: -40 +105 °C.
Features
TDA8594SD features: (1)Operates in legacy mode (non I2C-bus)and I2C-bus mode (3.3 V and 5 V compliant); (2)Three hardware-programmable I2C-bus addresses; (3)Drives 4 Ω or 2 Ω loads; (4)Speaker fault detection; (5)Independent short-circuit protection per channel; (6)Loss of ground and open VP safe (with 200W series impedance and a supply decoupling capacitor of 2200 uF maximum); (7)All outputs short-circuit proof to ground, supply voltage and across the load; (8)All pins short-circuit proof to ground; (9)Temperature-controlled gain reduction to prevent audio holes at high junction temperatures; (10)Low battery voltage detection; (11)Offset detection; (12)This part has been qualified in accordance with AEC-Q100.
