ADJUSTABLE-SPEED SINGLE-PHASE FULL-WAVE PRE-DRIVER FOR MOTOR
AM4967
General Description
Features
The AM4967 is a single-coil, single-phase motor pre- _{· Single-phase Full-wave Pre-drive}
driver designed by bipolar process. Its rotation speed _{· Rotation Speed Control via External PWM}
can be controlled through an external PWM. This IC _{· Maximum Operating Current Limit}
requires few external components and has the merit of
high efficiency which make it suitable for use in great
