Description
The DRV8704 customer EVM is a platform built around the DRV8704, a dual H-bridge brushed DC motor driver with highly-configurable power stage. This device is optimized to drive two different brushed DC motors with variable current limiting and an internal 5-V LDO for powering peripheral devices.The EVM includes two 555-timer circuits configured to switch at approximately 25 kHz with independently variable duty-cycles. Each 555 timer is tied to a jumper pin allowing the user to select which channel of the DRV8704 is receiving the PWM signal. This analog generation of PWM signals allows for standalone use of the EVM without any firmware being flashed onto a microcontroller.If the user would like to control the EVM using an MCU, the two 10×1, 100-mil headers can be docked to TI's MSP430™ LaunchPad™ and controlled using whatever firmware is supplied by the user. SPI commands can be written or read by simply docking the EVM to a LaunchPad or tying into the 4 SPI pins with another MCU.
Features
- Highly configurable SPI interface
- 8V to 52V supply voltage range
- Multiple decay modes
- Adjustable current regulation
- 5V, 10-mA LDO regulator
Typical applications
- Automatic Teller and Money Handling Machines, Office Automation Machines, Textile Machines
- Factory Automation and Robotics
