Hi everyone
I am working on an ESC design project for drones, using TI's reference design TIDA-00916 as a guide. I have a question regarding the measurement circuit design.I’ve noticed that when implementing sensorless FOC control for BLDC motors, there are typically two types of current sensing amplifier circuits: one that uses a 1.65V reference voltage, and another that doesn't.
Amplifier circuit with a 1.65V reference voltage.
Amplifier circuit without a 1.65V reference voltage.
I’d like to ask about the differences between these two configurations when used in BLDC motor control. For my project, which involves designing an ESC for drones, which configuration would be more suitable?
