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)
