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.
