Gate Drivers Overview Slide 5

The current portfolio for motor control is shown in the table on this slide. ST is making a strong focus on dual H-bridge products and stepper motor drivers. The L6470 is the current state of the art for stepper motors, but with integrated MOS it is limited to 45 V. If 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. Other new products are the SmartDRIVE family (L639x). In the ST portfolio, the bridges can be integrated, the driver, controller, power stage, and the power switch area that is the MOS, 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.
