I2C-Bus Controlled Dual Channel 43 W/2 Ohm Single Channel 85 W/1 Ohm Class-D Power Amplifier with Load Diagnostics

TDF8599 Active

The TDF8599 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. Low power dissipation enables the TDF8599 high-efficiency, class-D amplifier to be used with a smaller heat sink than those normally used with standard class-AB amplifiers.

The TDF8599 can operate in either non-I²C-bus mode or I²C-bus mode. When in I²C-bus mode, DC load detection results and fault conditions can be easily read back from the device. Up to five I²C-bus addresses can be selected depending on the value of the external resistor connected to pins ADS and MOD.

When pin ADS is short circuited to pin AGND, the TDF8599 operates in non-I²C-bus mode. Switching between Operating mode and Mute mode in non-I²C-bus mode is only possible using pins EN and SEL_MUTE.
