MTD6501G
The MTD6501G is a 3-phase full-wave driver for brushless sensorless DC motors. It features 180° sinusoidal drive, high torque output, and silent drive. Due to its adaptive features and wide power-supply range capabilities (2 to 14V), it is intended to cover a wide range of motor characteristics, while requiring no external tuning from the user. Speed control can be achieved through either power supply modulation or pulse-width-modulation (using the PWM digital input pin). Due to the compact packaging and minimum bill-of-material (power transistors incorporated, no Hall sensor, no external tuning), it is best suited for low-cost fan applications requiring high efficiency and low acoustic noise, such as CPU cooling fans. Frequency generator output is also included, enabling for precision speed control in closed-loop applications. The MTD6501G driver includes a lockup protection mode, which turns-off the output current when the motor is under lock condition, and an automatic recovery that enables the fan to run when the lock condition is removed. Motor over-current limitation, short-circuit protection, and thermal-shutdown protection are also included.
