M56750FP
3-PHASE BRUSHLESS MOTOR DRIVER
REJ03F0049-0100Z
Rev.1.0
Sep.19.2003
Outline
M56750FP is a 3 phase brushless motor driver that include charge pump circuit, which is inputted a acceleration and
deceleration pulse signal from a external discriminator circuit. The pulse width is converted to the voltage by the above
charge pump circuit and a external filter. And, the current in proportion to this voltage is outputted.
Features
• Wide voltage range: From 12V to 24V.
• High current capability : 1.0A
• Inclusion of current limit circuit.
• Inclusion of charge pump circuit.
• Inclusion of Hall-sensors drive circuit.
(This function is linked with a power save function.)
• Inclusion of power save function.
• Inclusion FG amplifier.
• Inclusion of Thermal Shut Down (TSD) circuit.
Application
Scanner motor of Laser Beam Printer.
