TDA75612LV数据手册ST中文资料规格书

描述 Description

The TDA75612LV is a new quad bridge car radio amplifier, designed in BCD technology, in order to include a wide range of innovative features in a very compact and flexible device.

The TDA75612LV is equipped with the most complete diagnostics array that communicates the status of each speaker through the I2C bus.

TDA75612LV has been designed to be very robust against several kinds of misconnections.

The TDA75612LV is equipped with the SSR (speaker safety routine), a procedure able to check the offset at the speakers and automatically shut down the power amplifier in case of dangerous DC voltage.

It is moreover compliant to the most recent OEM specifications for low voltage operation (so called 'start-stop' battery profile during engine stop), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection.
