TDA8595

TDA8595 I2C-bus controlled 4 × 45 W power amplifier Rev. 02 — 21 November 2007 Product data sheet 1. General description The TDA8595 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. It 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. www.DataSheet4U.com 2. Features 2.1 General I I I I I I I I I I I I Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant) Three hardware-programmable I2C-bus addresses Drive 4 Ω or 2 Ω loads Speaker fault detection Independent short-circuit protection per channel Loss of ground and open VP safe (with 150 mΩ series impedance and a supply decoupling capacitor of 2200 µF 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 I DC load detection: open-circuit, short-circuit and load present I AC load (tweeter) detection I During start-up, can detect which load is connected so the appropriate gain can ...
