31 / 40 page  DocID029806 Rev 2 31/40 STSPIN32F0 Device description 40 Figure 16. Driver logic overcurrent management signals 6.10 3FG_PA7 output function The 3FG_PA7 pin has a different function according toTable 13. When the 3FG function is selected the 3FG_PA7 pin works as the open-drain output (see Figure 17). The 3FG signal is synthesized from the Hall-effect sensors feedback applied to the op amp inputs. The analog output of the op amp is converted into a logic signal through internal comparators (Vref = VDD/2) and provided to Hall decoding logic. The 3FG resulting output signal is an exclusive-OR function of the three Hall sensors (see Table 14). Table 13. 3FG_PA7 pin function 3FG High Z (PA12) 3FG_PA7 Note 0PA7 Default 1 3FG The MCU pin must be configured with pull-up |
