PRODUCTION DATA.
There are two thermal sensors in TPS6572x located at the main sources of power dissipation: the charger and the LDO. The maximum temperature of the charger is regulated by reducing its charge current. If the temperature increases further, the charger is disabled. See details in Battery Charging.
The second sensor is enabled as soon as the LDO is enabled. As soon as the junction temperature, TJ, exceeds typically 150°C, the device goes into thermal shutdown. In this mode, the low side and high side MOSFETs are turned off. A thermal shutdown for the LDO will disable both, LDO and the DC-DC converter simultaneously.
