AP1037
Stepper Motor Driver IC equipped with Active Decay Control
1. General Description
The AP1037 is driver for bipolar stepper motors. It supports 35V motor power supply and 1.5A constant
current operation. The AP1037 can automatically control Decay setting (slow, fast, pre-fast) in the IC inside
by AKM original "Active Decay Control". The AP1037 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
AP1037 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 AP1037 is suitable
for the stepping motor drive in a space-saving and high current.

Note 2. All above voltages are with respect to GND. The each power supply of VC and VM is sequence-free.
Note 3. For Power Dissipation, the output current rating may be limited by duty cycle, Ta, and PCB board heat
sinking design.
Note 4. Exposed Pad must be connected to GND.
Note 5. A 4-layer JEDEC51 compliant board is used.
If the temperature exceeds 25°C, be sure to derate at Figure 2.
