Application Information
TS4975
28/33
During the device start-up period when the pop and click reduction is active, the value FX hex
(1111xxxx bin) can be read from the internal device registry.
Once the device is fully operational and the pop and click is inactive, the last value of control
register can be read.
4.9
Thermo shutdown
The TS4975 device has internal protection in case of over temperature by thermal shutdown.
Thermal shutdown is active when the device reaches temperature 150°C.
When thermo shutdown protection is active, value FX hex (1111xxxx bin) can be read from the
internal device registry.
When thermo shutdown protection state disappears, the last value of control register can be
read.
