DRV8811EVM Datasheet PDF - TI

●The DRV8811EVM evaluation module is a complete solution for evaluating the DRV8811 microstepping bipolar stepper driver. It houses a USB link to provide easy control from a PC computer, an MSP430 microcontroller that interprets serial commands from the PC and generates control signals to the driver device, and the DRV8811 device with access to all signals for a complete evaluation. The DRV8811 device has two H-bridge drivers, as well as microstepping indexer logic to control a stepper motor. The output driver block for each consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings. A simple step/direction interface allows easy interfacing to controller circuits. Pins allow configuration of the motor in full step, half step, quarter step, or eighth step modes. Decay mode and PWM off time are programmable. Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and over temperature.
