POWER DRIVER FOR DC MOTORS. Low Voltage Driver for One or Two DC Motors up to 2A (2.4A) peak – UART based Control for Torque and Velocity. 4 Half Bridge Peripheral Driver Option
TMC7300 DATASHEET (Rev. 1.01 / 2019-NOV-06) 2 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, UARTOA2High-LevelCPUTMC7300Interface and accesses diagnostic information OB2M via the UART interface. The TMC7300 OB1 takes care for voltage and current regulation and overcurrent protection. UART With single motor operation, output INTERFACE FOR CONTROL OF 1 DC MOTOR (UP TO 2.4A) current is increased and power OA1M dissipation is reduced.

It drives MA1, A2, B1, B2, HS resistive loads, like a LED, or inductive OA2ERRORTMC7300 loads like motors or solenoids. It OB2 offers up to 2A peak output current Current SenseOB1 while adding protection features. RLED The TMC7300-EVAL is part of TRINAMICs universal evaluation board system which provides a convenient handling of the hardware as well as a user-friendly software tool for evaluation. The TMC7300 evaluation board system consists of three parts: STARTRAMPE (base board), Eselsbrücke (connector board with test points), and TMC7300-EVAL.
