35 / 48 page  7 Application example Figure 23 shows an application example using the STSPIN32G4 device to drive a three-phase motor with triple shunt configuration and field oriented control algorithm. The other features implemented are: • VDD (3.3 V) power supply internally generated via LDO linear regulator • VCC (programmable, 8 V default value) power supply internally generated via Buck regulator • Reset dedicated pin • Overcurrent protection using internal comparators connected to op-amp positive inputs (PA1, PA7, PB0) • Current sensing using internal operational amplifiers and ADCs: – Op-amp 1: PA1, PA3, PA2 (OPP, OPN, OPO) – Op-amp 2: PA7, PC5, PA6 (OPP, OPN, OPO) – Op-amp 3: PB0, PB2, PB1 (OPP, OPN, OPO) • Bus voltage monitoring using internal ADC (PA0) • Application temperature monitoring using internal ADC (PC4) Table 26.
