PRODUCTION DATA
If the junction temperature rises above the thermal warning threshold of 150 °C (typical), the device sets the TWARN bit in the STATUS register. The device clears the TWARN bit if the STATUS register is read after the junction temperature fell below the TWARN threshold of 130 °C (typical).
If the junction temperature rises above the thermal shutdown threshold of 170 °C (typical), the device:
If the junction temperature then falls below the thermal shutdown threshold of 150 °C (typical), the device:
The device clears the TSHUT bit if the user reads the STATUS register after the junction temperature fell below the TSHUT threshold of 150 °C (typical).
In a stacked configuration, in which all devices share a common enable signal, a thermal shutdown condition in one device disables the entire stack. When the hot device cools down, the whole stack automatically starts switching again.
