HA13609ANT
Three-Phase Brushless Motor Driver
ADE-207-232 (Z)
1st. Edition
May 1997
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)
