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.
