Can do s12zvl Sensorless BLDC controlcontrol with One shunt ?

If it can do How can use nxp LIB ?

Hi Ahn,

Unfortunately s12zvl is not directly designed for driving BLDC motor.

You will probably need external FET driver. Please look at hardware solution for older S12G family:

Or you could choose one of s12zvm family derivatives with gate drive unit module and drive BLDC motor directly. For more details, please look at:

I hope it helps you.

Have a great day,
RadekS

Thanks your kindly mention of my question

I know s12zvl is
not directly Motor control it must be with FET or IGBT

So, My question is
using just one shunt for FOC-sensorless BLDC MOTOR control with NXP LiB

Normally, Sensorless
control is using with 3-shuts or 2-shunts

Can s12zvl control Sensorless
BLDC motor with just one-shunt?
