TechnologyThe Microchip Technology TC647VUA is an electronic Motor / Motion / Ignition Controller & Driver with Fault Detection. It is a low-cost, 3-channel motor controller and driver with diagnostic protection for industrial and commercial applications. This device is designed to provide flexibility in the control of motors and motion applications in industrial control systems. The device can be used in applications such as motor controllers, motion controllers, robotic controllers, and industrial automation systems. The TC647VUA features three individual diagnostic protection inputs for monitoring motor phase faults, overvoltage or undervoltage, and overtemperature. The fault detection from the diagnostic protection inputs is used to protect the connected motor from damage due to over-currents, under-voltage, and over-temperature conditions. The TC647VUA also provides a wide range of operating frequencies and pulse widths to meet the specific control requirements of the application.
