General description:
Features
The TDA8596 is a quad Bridge Tied Load (BTL) audio power amplifier with symmetrical inputs, made in BCDMOS technology. It contains four independent amplifier channels in BTL configuration with complementary (PMOST/NMOST) output stages. Temperature warning and output signal clipping diagnosis is possible via the I2C-bus and via the diagnostic pins (DIAG and STB pin). The temperature pre-warning level and clip detection levels can be programmed via the I2C-bus. The status of each amplifier channel (i.e. output offset, load connected or not, short circuit condition at the output pins) can be read out separately.
Features
- 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 Ω or 2 Ω loads
- Balanced/symmetrical inputs
- Speaker fault detection
- Programmable gain (26 dB and 16 dB) also available in legacy mode
- Independent short circuit protection per channel
- Loss of ground and loss of VP safe (with 300 mΩ series impedance and a maximum supply decoupling capacitor of 2200 µF)
- All outputs are short-circuit proof to ground, supply voltage and across the load
- All pins are short circuit proof to ground
- Temperature-controlled gain reduction to prevent audio holes at high junction temperatures
- Low battery voltage detection
- Qualified in accordance with AEC-Q100
