Does st have bldc sensorless library?

1 It is better to use integration, which will increase the cost. After all, the separated driver is not as reliable as the integrated front driver, and it is easy to find problems. Hehe, the principle of integration or separation is the same, and bootstrap circuits are used.

2 is the product. Now the BLDC plan is mature. In fact, the annoying scheme is very simple, which is nothing more than MCU+ pre-driver +MOSFET+ current and Hall position signal feedback.

Regarding the library, ST is FOC, and I wrote it myself according to the control logic of ST.

The above are just a few suggestions for reference only.
