AP1025BEN
45V Single Stepper Motor Driver IC
1. Description
The AP1025BEN provides a complete stepper motor driver solution with built-in LDMOS FET and its
internal capacitors type charge pump circuit for the 45V & 1.6A constant current operation. Clock-in input
mode and Parallel input mode is selectable by the setting of an external terminal. 2 phase, 1-2 phase(1/2step),
W1-2 phase(1/4step) can be selected during parallel input mode, and 2 phase, 1-2 phase(1/2step), W1-2
phase(1/4step), 4W1-2 phase(1/16step) can be selected during clock-in input mode to realize calm motor
operation. The IC is housed in a small 32-pin QFN package and excellent in heat dissipation. It also includes
under voltage detection and thermal shut down circuits. It is suitable for various types of stepper motors.
2. Features
