Microcontroller drives H bridge to power a permanent-magnet dc motor

Focus:

For driving low- to medium-power permanent-magnet dc motors, an alternative to the conventional H-Bridge driver operates with only two low-side control signals. By not requiring the usual two high-side control signals, this circuit avoids the need for isolation and level shifting circuits.

What you’ll learn:

• How to build an H-bridge driver that requires only two low-side control signals
