APPLICATION EXAMPLES: SIMPLE SOLUTIONS – HIGHLY EFFECTIVE
The TMC7300 scores with a high power density using integrated power MOSFETs and a complete integrated DC motor control logic, to control velocity and limit torque, or for torque controlled operation. It covers a wide spectrum of applications from battery systems to embedded applications with up to 2A (2.4A) current per motor. Extensive support enables rapid design cycles and fast time-to- market with highly competitive products.
UART INTERFACE FOR CONTROL OF 2 DC MOTORS
A CPU operates the driver via its UART
OA1
interface. It configures motor direction
M
and velocity as well as current limit,
