Description
ADJUSTABLE-SPEED SINGLE-PHASE FULL-WAVE PRE-DRIVER FOR MOTOR
Manufacturer
BCDSEMI [BCD Semiconductor Manufacturing Limited]
Datasheet
General Description
The 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 make it suitable for use in great
air volume, large current and high voltage applications.
The AM4967 is available in SSOP-16 package.
