PMIC - Motor Drivers, Controllers are widely used in many areas, such as transportation, industrial, medical, and home and building automation. The TC649EOATR is a non-isolated, low-power, adaptive and compact DC motor driver with a wide range of operating voltages and low on-resistance channel. The main components are high-current MOSFETs, current sense amplifiers and controllers. The fully integrated solution is made up of a full bridge driver IC, a current sense amplifier and a thermal control system.

The TC649EOATR is designed to drive a range of DC brushless motors, in the range of 0.5A to 8A, typically with a supply voltage of 12V to 24V. It provides a high level of protection to the motor, with current limiting and over-temperature shut-down features. The inputs for the driver are compatible with logic level and PWM signals, making it suitable for control from a variety of micro-controllers and programmable logic controllers. The device also supports 3-phase brushless motor applications, a cost effective alternative to multi-IC solutions.

The turn on/off thresholds of the gate drive outputs can be adjusted to reduce gate charge and switching losses. The TC649EOATR features a low-resistance bridge for high current applications, allowing for low drive voltage and high current capacity motor operation. In addition, it also provides an advanced thermal control system to protect the device and the motor.

The built-in advanced current limiting circuitry allows the TC649EOATR to monitor the current utilization of the motor. It continuously adjusts the main current according to the actual current usage, which in turn helps to reduce power consumption and prolong motor life. It also provides over-temperature shut-down, to protect the device from excessive heat. The TC649EOATR features a variety of safety features, such as over voltage, over current and short protection.

The TC649EOATR is suitable for a range of applications, such as automotive, consumer, industrial, medical and safety systems. It provides a comprehensive feature set and an ideal way to control a variety of DC brushless motors, without the need of complex control circuitry and expensive components.
