GENERAL DESCRIPTION
The AP1034 is driver for bipolar stepper motors. The AP1034 can achieve optimal current setting, therefore will reduce current ripple and bring the motor rotation operation of the high efficiency. The input interface is clock-in method and supports from 2 Phase (full step) to 2W1-2 Phase (1/8step) excitation. In addition, the AP1034 is built-in a regulator for control circuit and capable of driving a motor only by motor power supply voltage (VM), therefore can facilitate design for the application. It is housed in a small QFN package with good heat dissipation performance, therefore the AP1034 is suitable for the stepping motor drive in a space-saving and high current. 2. FEATURES
