ICs for Motor
AN8245K, AN8245SCR
Laser Disk Spindle Motor Controller
s Overview
The AN8245K and AN8245SCR are speed control drive ICs of the brushless motors by means of the 3-phase fullwave current drive system. They are suitable for controlling/driving the laser disk spindle motors, LBP polygon mirror motors, and so on.
s Features
Operating supply voltage range : VCC1=10.8 to 13.2V VCC2=10.8 to 22V
3-sensor 3-phase full-wave current drive ; power
transistor built-in
Maximum motor drive current : IMmax.=1.5A Digital PLL control Bidirectional torque control Provided with reverse detector and stop detector Synchronizing signal and stop signal output Built-in thermal protective and current limiter functions
s Applications
Control and drive of the Hall motors such as laser disk spindle motors, LBP polygon motors, and so on
