CodePudding user response:

IO pin is PC1? To see whether the PC1 is dried shrimp circuit is concerned,

CodePudding user response:

PC1 is STM32 an IO port

CodePudding user response:

PC1 is high, the OUT 15 v output minus the Q1 Vds

CodePudding user response:

Excuse me, could you detailed analyze the zha work and the selection of resistance tolerance if you have any questions

CodePudding user response:

Is to triode don't understand, or to field effect tube don't understand?

CodePudding user response:

In the BBS questions are mostly this kind of circuit, in the form of amplification, but triode not only enlarge connection this, studied the circuit should know some basic circuit connection,

CodePudding user response:

Can participate

CodePudding user response:

This is a typical power switch circuit, MOS tubes do add an NPN transistor because MOS tube s-class is 15 v, MCU can't direct drive,

CodePudding user response:

MOS tube through triode control Suggestions at 4.7 K with a grounding resistance can reduce the current

CodePudding user response:

R1 make bigger, at least to make into 4 k7, still less a number
