Application example

Figure 19 shows an application example using the STSPIN32F0 device to drive a three-

phase motor with single shunt configuration and analog Hall-effect sensors feedback. The

others features implemented are:



VDD (3.3 V) power supply internally generated via DC/DC regulator



VREG12 (12 V) power supply internally generated via LDO linear regulator



I2C serial interface (PB6 and PB7)



Serial wire debug ports (PA13_SWD_IO, PA14_SWD_CLK)



Ready and alarm lines (PF0, PF1)



Reset dedicated pin



Overcurrent protection using internal comparator



Current sensing using internal operation amplifier (op amp 1) and ADC (PA3)



3FG generation using internal op amps, comparators and Hall decoding logic circuitry

(op amp2, 3, 4 and relative comparators)



Hall-effect sensors feedback management with op amps and ADC (op amp2, 3, 4 and

PA0, PA1, PA2)



Bus voltage compensation using internal ADC (PA4)



Application temperature monitoring using internal ADC (PB1)
