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.
Function
• Power MOS and power bipolar transistor driver circuits
• 16-bit serial interface
• Variable-speed digital speed control circuit
• Digital PLL
• Digital ready circuit
• PWM oscillator circuit
• Charge pump circuit
• Integrating amplifier circuit
• Current limit circuit
• Overshoot prevention circuit
• Braking function (with braking compete signal)
• Forward/reverse direction circuit
• Hall open circuit protection
• Watchdog timer (LVI, POR, and RST outputs)
• Stuck rotor protection
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)
