and AC load detection)
Flexible fault detection through integrated
diagnostic
DC offset detection
Four independent short circuit protections
Clipping detector pin with selectable threshold
(2 %/10 %)
Standby/mute pin
Linear thermal shutdown with multiple thermal
warnings
ESD protection
Very robust against misconnections
Improved SVR suppression during battery
transients
Capable to operate down to 6 V (e.g. “Start-stop”)
Selectable SSR (speaker safety routine)
Description
The TDA75616LV 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 TDA75616LV is equipped with the most
complete diagnostics array that communicates
the status of each speaker through the I2C bus.
TDA75616LV has been designed to be very
robust against several kinds of misconnections.
The TDA75616LV 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.
