TDF8597TH/N1 Product Details

The TDF8597 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising anNDMOST-NDMOST output stage based on SOI BCDMOS technology. The TDF8597 fullysupports start/stop systems as it can operate at a battery voltage as low as 6 V. TheTDF8597 can be controlled with or without I2C. I2C allows control of load detection resultsand fault conditions to be read. The TDF8597 is a high efficiency class-D amplifier withlow dissipation. Due to the low dissipation, the device can be used with a smaller heat sinkthan standard class AB amplifiers. Six different I2C addresses can be selected withexternal resistors connected to the ADS and MOD pins. If pin ADS is a short-circuit toground, 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.
