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

) 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

) for the time specified by the Thermal Error Retry Time (R

) in

order for the device to automatically return to normal operation.

Both T

and R

are specified in “Electrical Characteristics - All Operational Modes” on page 9.
