Recommended Power-Down Sequence
1. Mute the audio supplied to the CS35L00.
2. Pull the SD pin low in order to reset the device and put it into the low power mode.
3. The power supply to the CS35L00 can now be removed.

5.5 Over Temperature Protection
The CS35L00 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.
