TPS63036: over temperature shutdown solution

Hi,

My customer is evaluaitng TPS63036. the device's performance is fine, but they have a specific requirement. once the temperature exceed 70°, the device need to shutdown, output to 0V. once temperature is below 70°，recover the output.   no MCU involve, they need a pure analog solution, either a new device with a intergrated temperature, or add a external temperature sensor which can output 0 or 1 to control EN pin at this very temperature.  

please kindly provide your comments, thanks.
