DRV8885EVM Application Field and Working Principle

DRV8885EVM is an Evaluation and Demonstration Boards and Kits that operates at high-current peak. It is designed to be a flexible development tool for evaluation and application development with a DRV8885 dual-H-bridge motor driver. It has been specifically designed for features such as: current regulation, current limit, thermal protection, as well as diagnostics and test circuit for measuring motor current and motor speed.The DRV8885EVM utilizes the DRV8885 motor driver which is a high-performance, dual-H-bridge motor driver with integrated 1.2 A H-bridge power MOSFETs. The DRV8885EVM is used to evaluate the performance, robustness and capabilities of the DRV8885 motor driver for applications in various motor control systems. With its built-in diagnostics and support for low-voltage systems, the DRV8885EVM is a great choice for motor control designs.The DRV8885EVM has an on-board Cortex-M0 processor, which features integrated, programmable I/O pins, allowing for easy connection of various peripherals and sensors. The control logic for the DRV8885EVM is based on the dedicated EEPROM on board. This allows designers to quickly develop firmware for controlling the DRV8885 motor driver for various applications.The DRV8885EVM comes with a selection of components for quickly assessing motor control performance. Included are rated polyimide film power MOSFETs, a power supply and an enclosure to keep it all together. It also includes an integrated oscilloscope, a micro-controller, a flash memory, a motor control demo, and various I/O interfaces (USB, Ethernet, and CAN). With the power of the Cortex-M0 processor, designers can quickly evaluate and test their DRV8885 motor driver applications.When it comes to the working principle of the DRV8885EVM, the motor driver provides drivers and signals to the motors, allowing a user to control the motor speed, direction, and position. The micro-controller on board acts as the motor controller by providing digital input signals to the DRV8885 motor driver. The DRV8885EVM application allows the micro-controller to vary the motor speed and direction with an external current source or by controlling the digital I/O of the DRV8885EVM board. Additionally, the micro-controller\'s onboard EEPROM allows for the storage of control functions that can be changed on the fly. The DRV8885EVM also offers integrated safety features, such as overcurrent protection and thermal protection, to help prevent damage. The integrated current sensing pins allow the motor driver to detect excessive current in the system and take action if it is exceeded. Additionally, the thermal protection feature of the DRV8885 motor driver allows for precise motor temperature monitoring through the device\'s multiple temperature isolated test points.To help maximize design life and reduce the effects of EMI, the DRV8885EVM also includes power MOSFETs with high-temperature stability and low-noise operation. These advanced power MOSFETs have an on-resistance of 6.5 mΩ(maximum) and a maximum gate-charge of 80nC, for significantly shorter switching times. The DRV8885EVM is a great choice for applications ranging from battery-operated systems to industrial motor control systems. With its integrated diagnostics, advanced safety features, and support for low-voltage systems, the DRV8885EVM is an invaluable tool for any motor control design.
