11.11 Die Temperature Sensor

The AT73C246 features a die temperature sensor for protection reasons. If the junction temper-

ature rises above the shutdown threshold for a minimum time of 1ms (+/- 5%), the power

manager event T

> 130°C is asserted. In a similar fashion, if the temperature falls through the

restart threshold for more than 1ms, the power manager event T

<110°C is asserted.

The two internal thresholds shutdown and restart are defined in Section 9.11 “Die Temperature

Sensor” on page 21.
