Analog input section
The STNRGPF01 device includes four fast analog comparators, from COMP0 to COMP3.
COMP3 and COMP2 have external reference voltages and are used to define the duty cycle
of the PWM[0] master.
COMP1 and COMP0 have internal reference voltage and are used to implement the
overcurrent protection features.
Figure 6. Analog comparators section
The positive inputs of COMP3 and COMP2 are on pin 24 and pin 25. Moreover, these
comparators use a common external triangular reference voltage connected to pin 26.
The positive inputs of COMP1 and COMP0 are configured on pin 27 and pin 28.
