Description
The HA13609ANT is a 3-phase brushless motor driver IC with digital speed control. It is designed for use as a PPC or LBP scanner motor driver and provides the functions and features listed below.
 

Features
•  High breakdown voltage (50V/30mA) power transistor drive circuit
•  PWM drive
•  Variable speed control is possible (varying the servo filter constants is not required)
•  Selectable rotation control method (discriminator control, PLL plus discriminator control)
•  Selectable feedback type (voltage or current)
•  Allows both PWM frequency switching and 100% duty operation
•  Selectable current limiting level
•  Braking mode selection (reverse braking, regeneration braking)
