The Texas Instruments (TI) DRV201EVM Evaluation Module (EVM) features an advanced motor driver designed to efficiently supply power to 3-phase brushless DC (BLDC) motors. The highly integrated DRV201EVM solution is capable of driving motors from a single supply up to 48V. With its six channels, this evaluation module can be used to drive different motor shapes such as Brushless DC motors (BLDC), Permanent Magnet Synchronous Motors (PMSM) or Stepper motors.

The main application field of the DRV201EVM is motor control. Motors are of great importance in any electronic system which implies movement or physical action. Electronic systems with motors can be found in the industrial, aerospace, automotive, consumer and medical sectors. Whether for high-force actuation in aerospace, flexible assembly systems in consumer goods, precise positioning applications in medical control or precise motion control in medical robotics: The DRV201EVM is a perfect fit for any customer who needs to drive a 3-phase BLDC motor from a single supply.

The DRV201EVM is based on a 3-phase motor driver module from TI, the DRV201. The DRV201EVM uses many of the features and capabilities of this driver module, combined with a board layout and design optimized for efficient driving of BLDC motors. The module is able to drive motors up to 48V, and it can achieve a maximum output current of 2.2A per phase. The DRV201EVM is able to modulate both direction and speed of the motor.

The main components of the DRV201EVM are the DRV201 driver module from TI, the DRV201 ADC (analog-to-digital converter) and the DC/DC converter. The DRV201 driver module is a 3-channel VLSI motor driver, featuring 3 banks of 6 VLSI outputs. The DRV201 ADC is an 8-bit sigma-delta adc capable of measuring both temperature and current. The DC/DC converter is a low-noise, high-efficiency switcher used to provide power to the DRV201EVM module.

The DRV201EVM has a wide range of features for both development and evaluation purposes. It contains timers and counters to support pulse-width modulation (PWM) and speed control. Additionally, its onboard current sensing and temperature measurement enables the user to monitor motor performance. To further support development, the DRV201EVM has a network of capacitors and ferrite beads that helps with noise suppression to reduce EMI.

The DRV201EVM has a proprietary JTAG interface for programming, providing an easy way to configure and monitor the device. The JTAG interface can be used to debug the code to optimize motor speed and performance. Through the use of the debugger, the designer can easily detect errors such as motor stall or fault. The resultant debugger can be used to improve the design, allow for production test and reduce time-to-market.

In conclusion, the DRV201EVM is a complete motor control solution that enables designers to quickly develop and evaluate motor control applications. Its ability to accurately sense current and temperature, along with its ability to drive motors up to 48V and 2.2A per phase makes it a perfect fit for a variety of motor control applications. Finally, the user-friendly JTAG interface enables the user to quickly debug and optimize motor speed and performance.
