ADJUSTABLE-SPEED SINGLE-PHASE FULL-WAVE PRE-DRIVER FOR MOTOR AM4967
General Description
The AM4967 is a single-coil, single-phase motor predriver 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.
Features
Single-phase Full-wave Pre-drive Rotation Speed Control via External PWM Maximum Operating Current Limit Linear Start Function for Reducing Large Current Impulse at the Moment of Turn-on Minimum Rotation Speed Setting Lock Protection and Auto Start Function Rotation Speed Indication Over Temperature Protection
Application
CPU and OA (Office Automation) Cooler Fan Brushless DC Motor
