TC649EUATR PMIC - Motor Drivers, Controllers

The TC649EUATR is a versatile Power Management Integrated Circuit (PMIC) and is applicable for many applications. It is a general purpose Precision Motor Driver, Controller, and Switcher that offers high-efficiency, high-performance regulation and protections for driving DC motors in all types of applications.The TC649EUATR is specifically designed for automotive applications and has been tested for compliance with all relevant automotive standards. Its features and robust design make it suitable for a wide range of automotive and non-automotive applications including motor control and protection, fans, pumps, and other general purpose power conversion applications.The TC649EUATR is designed to be used as a motor driver or controller in applications that require high efficiency and performance, while still remaining cost-effective. The chip can deliver up to 500 mA/per phase with an adjustable gate pulse width and is designed with a maximum duty cycle of 40%. The operating frequency can be adjusted up to 40 kHz, with an adjustable fault response time up to 100 µs. The chip provides a wide range of fault protection functions that can be enabled by external resistors and interrupts. The TC649EUATR includes four-channel PWM drivers to control the speed, direction and braking torque of brushed or brushless DC motors up to 30V and programmed with up to 4-step current control for improved dynamic control. While in motion, the chip can detect any sudden increase or decrease in current and set the speed accordingly. The driver also features a back-EMF sensing input, built-in OVP & HDD protection, and Auto-Servo-Tune algorithms to reduce the load and minimize disturbances.The chip also includes a comprehensive set of built-in safety features, such as a thermal shutdown, high peak current protection, over-temperature protection, short circuit protection, and an under-voltage lockout. This makes it an ideal choice for applications where robust protection and reliability are necessary, such as automotive motor control.Finally, the TC649EUATR is designed to be easy to integrate into existing designs with minimal external components. The chip features an adjustable threshold voltage for detecting under voltage and over voltage, as well as an integration of a high-current current-sense amplifier. It also includes an SPI interface for programmability.Overall, the TC649EUATR is a highly versatile PMIC and motor driver, controller, and switcher that is designed to offer reliable performance and cost-effective operation in a wide range of applications. It is a great choice for automotive motor control applications, as well as general motor control and protection applications.
