5.5 Over Temperature Protection
The CS35L01/03 is internally protected against thermal overload. Built in die temperature sensing circuitry
monitors the die temperature and will place the device into shut-down if thermal overload occurs. A ther-
mal overload is characterized by the die temperature reaching the Thermal Error Threshold (T
TE
) at which
time the outputs will tristate and shut down.
If the device has entered into shut-down due to a thermal overload, the die temperature must remain be-
low the Thermal Error Threshold (T
TE
) for the time specified by the Thermal Error Retry Time (R
TE
) in
order for the device to automatically return to normal operation.
Both T
TE
and R
TE
are specified in “Electrical Characteristics - All Operational Modes” on page 9 .
