7.3.3 Enable and Thermal Shutdown

The TPS61500 enters shutdown when the EN voltage is less than 0.4 V for more than 10 ms. In shutdown, the input supply current for the device is less than 1.5 μA (maximum). The EN pin has an internal 800-kΩ pulldown resistor to disable the device when it is floating.

An internal thermal shutdown turns off the device when the typical junction temperature of 160°C is exceeded. The device restarts when the junction temperature drops by 15°C.
