Gate Drivers Overview Slide 31

In summary, the current STMicroelectronics has a large portfolio to meet most of motor control requirements and stepper motor drivers. The L6470 is a state of the art driver for stepper motors, and is limited to 45 V maximum. In designs where a higher voltage device is required the L6480 is very similar to the L6470 but the dual-H bridge is replaced by eight gate drivers for external MOSFETs. The SmartDRIVE family (L639x) integrates the bridges, the driver, controller, power stage, the power switch area, and the gate drivers. The L6480 is a dual H-bridge gate driver, and all the products of the L6390 family are half-bridge gate drivers.
