TDA8596TH中文资料I2C-bus controlled 4 x 45 W power amplifier with symmetrical inputs数据手册恩XP规格书

描述 Description

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.

特性 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 W or 2 W 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 mW series impedance and a maximum supply decoupling capacitor of 2200 mF)
• 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
I2C-bus mode
• DC load detection: open (no load), normal load, line-driver load
• AC load (tweeter) detection
• Detect which load is connected during start-up to allow the system to be configured to select the gain accordingly (e.g. line-driver mode or normal mode).
• Independently selectable soft mute of front (channel 1 and channel 3) and rear channels (channel 2 and channel 4)
• Independently programmable gain (26 dB and 16 dB) of front (channel 1 and channel 3) and rear (channel 2 and channel 4) channels
• Flexible programmable diagnostic levels:
• Programmable clip detect: 2 %, 5 % or 10 %
• Programmable thermal pre-warning
• Selectable information on the DIAG or STB pin:
• The STB pin can be programmed/multiplexed with second clip detection
• Clip information of each channel separately can be directed to the DIAG pin or the STB pin
• Independent enabling of thermal-, clip- or load fault (short across the load, to VP orto ground) available on the DIAG pin
• Offset detection
