TM
The DIODES AM4967 is a single-coil, single-phase motor pre-driver
designed by bipolar process. Its rotation speed can be controlled
through an external PWM. This IC requires few external components
and has the merit of high efficiency which makes it suitable for use in
great air volume, large current and high-voltage applications.
