Figure 10. Analog comparators section

A description of the comparator pins is reported below.

•

Pin 24 OUT_PI[3]: Positive input of COMP3. It receives the out of analog PI current.

•

Pin 25 OUT_PI[2]: Positive input of COMP2. It receives the out of analog PI current.

•

Pin 26 TRIANG_REF: Negative common input analog COMP2,3. It receives the reference triangular

waveform.

•

Pin 27: Positive input of COMP1. It receives the sensing signal of total input current.

•

Pin 28: Positive input of COMP0. It receives the sensing signal of all switch currents.

COMP0 stops the driving when an overcurrent occurs in any switch.
