The AP1037AER employs original technique the first in the industry “Active Decay Control”, so is high efficient stepper motor drivers.The “Active Decay Control” reduces the current ripple while maintaining the current follow-up capability,because adjusts the motor current automatically. The AP1037AER is suitable for OA-equipment such as Multi-functional Printers (MFP).\nActive Decay ControlFeaturesHigh EfficiencyThe AP103X series adopts “Active Decay Control” reducing the current ripple while maintaining the current follow-up capability; therefore a high efficient motor driving is realized. The AP103x series is housed in a small package since high efficiency of the device helps suppressing heat generation. Therefore a printed circuit board can be downsized.Smooth Motor Drive and Low VibrationThe AP103x series provides smooth and low vibration motor rotation by supporting micro-stepping drive from 2 (full step) to 2W1-2 (1/8step) phase excitation. It is capable of controlling the current in high precision. Automatic Decay ControlThe “Active Decay Control” adjusts the motor current automatically. Therefore, designing man-hours can be reduced by eliminating the need for Decay setting that is controlled by external parts.
