Abstract

To choose an appropriate gate driver, it is important to consider the balance of robustness, size versus cost, and compatibility with other system components (for example, the microcontroller and power switches). This application note focuses on gate driver ICs for DC motor drives like brushless DC, stepper, or linear motors. Table 6-1 and Table 6-2 summarize common design considerations and compare relevant half-bridge and low-side gate drivers.
