13.6 Thermal monitors

The PF09 features nine temperature sensors spread around the die. The main thermal management sensor is

located at the center of the die, and the rest are located in the vicinity of the voltage regulators:

• Center of die

• Vicinity of SW1

• Vicinity of SW2

• Vicinity of SW3

• Vicinity of SW4

• Vicinity of SW5

• Vicinity of LDO1

• Vicinity of LDO2

• Vicinity of LDO3

The output of the temperature sensors is internally connected to the AMUX, allowing the user to read the raw

voltage equivalent to the temperature on each sensor. Sensor temperature at any point is calculated with the

following formula:

Where VTSENSE is the thermal sensor voltage measured on the corresponding AMUX channel.

The temperature sensor at the center of the die is used to generate thermal interrupts and thermal shutdown.

The processor can read outputs of the other temperature sensors and take appropriate action (such as reducing

loading, or turning off a regulator) if the temperature exceeds desired limits at any point in the die.
