TDF8597TH数据手册恩XP中文资料规格书

描述 Description

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.
