12.13 Cycle-by-cycle Current Limit

The ACT72350 contains hardware support for cycle by cycle current limit. The user may configure this

feature to use the LPCOMP DAC as the current threshold. The CAFE will automatically perform duty

cycle truncation to lower current at any time the associated phase current is greater than the setting of the

LPCOMP DAC.

12.14 Temperature Protection

The ACT72350 contains an internal temperature sensor that detects temperature warnings and faults.

When the device temperature reaches the temperature warning threshold (140ºC), the device sets an

over-temperature warning condition. The user may configure a mask-able interrupt the MCU for this

condition, through the nFAULT output.

When the device temperature reaches the temperature fault threshold (165 ºC), the device is shut down.

This condition will always assert the nFAULT output.

For more details on the register settings for over-temperature protection see the ACT72350 User Guide

and related application notes.
