HA13532NT
Three-Phase Stepping Motor Control IC
Description
The HA13532NT is an IC for control a three-phase stepping motor.
Functions
• PWM current control
• Low-voltage inhibit (LVI)
• Three-bit D/A converter for current programming
• Motor on/off
• Selectable 2-phase or 2-3-phase exciting
Features
• Wide operating voltage range
• Few external components
