A full-bridge converter drive consists of four power switches used to adjust the motor voltage and polarity using pulse width modulation (PWM). The current can thus be controlled to flow in either direction through the motor windings, allowing the motor to run in both directions.

At lower power levels, ST offers a wide set of monolithic motor drivers which, with a progressive choice of integrated features, embed gate drivers, power transistors, protection functions and even DC-DC converters.

For higher powers, ST’s portfolio includes power transistors and high-voltage gate drivers to implement the required H-bridge. A general-purpose 8-bit microcontroller such as the STM8S can be used to implement these control strategies.
