We offer full-bridge motor drivers to drive bipolar stepper motors or implement bidirectional control of two DC motors. Their wide operating voltage range and easy integration with microcontrollers (MCUs) makes them excellent options for a variety of applications including security cameras, ticketing systems and home appliances. We also offer full-bridge motor gate drivers to drive brushed DC motors in automotive body and powertrain applications.
