AP1034
Stepper Motor Driver IC equipped with Active Decay Control
1. General Description
The AP1034 is driver for bipolar stepper motors. It supports 35V motor power supply and 2.0A constant
current operation. The AP1034 can automatically control Decay setting (slow, fast, pre-fast) in the IC inside
by AKM original "Active Decay Control". 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.

DIR : Motor Rotation Direction Setting Terminal
This pin sets the direction of motor rotation. When changing the direction, a new setting is reflected on a rising
edge of the CLK pin. Refer to Figure 6.
・CCW : H-bridge2 current is output by shifting 90deree ahead against the H-bridge1 current.
・CW : H-bridge2 current is output by shifting 90degree behind against the H-bridge1 current.

RESETB : Home Position Setting Terminal
When the RESETB input is “H”, the sequencer is set at home position, and all the H-bridge outputs become off
(motor output becomes Hi-Z). In this case, STEP input is ignored until “H” is input to the RESETB terminal.
The internal circuits are in enable state. Refer to Figure 7.
