TDA8586 Power Amplifier With Load Detection And Auto BTL/SE Selection

The device incorporates the following functions:4 x 6 W SE amplifies without SE capacitor, because of the availability of 2 half supply voltage power buffers2 x 20 W BTL amplifiersAutomatic switching between 2 and 4 speaker operation. The mode of operation is determined during start-up. This Amplifier is protected for all general short-circuit conditions to battery or ground, overvoltage, 45 V load dump and short-circuits on the speaker outputs. The device is contained in a 20-pin power HSOP package, but is also available in a 17-pin SIL power package. When packaged in the 20-pin HSOP package additional functions are available: DDD level selection between 2 and 10pctOverrule pin for changing mode of operation (from SE to BTL or from BTL to SE).
