Description


The MTD6501C/D/G 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
materials (power transistors incorporated, no Hall
sensor, no external tuning), they are best suited for lowcost 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/D/G drivers
include a Lock-up 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 overcurrent
limitation, short-circuit protection and thermalshutdown protection are also included.
