Description
The MTD6501C/MTD6501D devices are 3-phase full-
wave drivers for brushless sensorless DC motors. They
feature 180° sinusoidal drive, high torque output, and
silent drive. Due to their adaptive features and wide
power-supply range capabilities (2V to 14V) they are
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 sen-
sor, no external tuning), they are best suited for low-
cost fan applications requiring high efficiency and low
acoustic noise, such as CPU cooling fans. Frequency
generator output enables precision speed control in
closed-loop applications. The MTD6501C/MTD6501D
drivers include a lock-up protection mode, which turns
off the output current when the motor is under lock con-
dition, and an automatic recovery that enables the fan
to run when the lock condition is removed. Motor
overcurrent limitation, short-circuit protection, and
thermal-shutdown protection are also included.
The MTD6501C is available in a compact thermally-
enhanced SOP-8 package, while the MTD6501D is
available in the MSOP-10L package.

... Boost Mode (MTD6501D) The Boost mode is an optional BEMF pre-amplification by a factor of 3. The interest of the Boost mode is to compensate for motors with a low coupling coefficient (= BEMF coefficient), thus allowing to cover an even wider range of motor characteristics. Notice that the Boost mode impacts the mechanical performance of the motor altogether ...
