I2C-bus controlled dual channel 43 W/2 Ω, single channel 85 W/1 Ω class-D power amplifier with full diagnostics

The TDF8597 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. The TDF8597 fully supports start/stop systems as it can operate at a battery voltage as low as 6 V. The TDF8597 can be controlled with or without I²C. I²C allows control of load detection results and fault conditions to be read. The TDF8597 is a high efficiency class-D amplifier with low dissipation. Due to the low dissipation, the device can be used with a smaller heat sink than standard class AB amplifiers. Six different I²C addresses can be selected with external resistors connected to the ADS and MOD pins. If pin ADS is a short-circuit to ground, the TDF8597 operates in non-I²C mode, and no I²C communication is possible. Use pins EN and ON to switch to operating and mute modes.
