DESCRIPTION

· The AP1037 is a bipolar stepper motor driver supporting 35V motor power supply and 1.5A constant current operation.

· It features AKM's original "Active Decay Control" for optimal current setting, reducing current ripple and enhancing motor efficiency.

· The driver uses a clock-in method for input interface and supports excitation modes from 2 Phase (full step) to 2W1-2 Phase (1/8 step).

· It includes a built-in regulator for the control circuit, enabling motor drive solely by motor power supply voltage (VM).

· Housed in a compact QFN package with excellent heat dissipation, it is ideal for space-saving and high-current applications.

FEATURES

· Built-in PWM current control and Active Decay Control.

· Single power supply operation with a built-in regulator.

· Motor operating voltage range from 8.0 to 35.0V.

· Maximum output current of 1.5A.

· On-resistance (High+Low) of 0.95Ω (typ.) at Ta=25℃.

· Supports clock-in method input interface and multiple excitation modes.

· Selectable PWM chopper frequencies of 39kHz and 77kHz.

· Includes spike noise blanking, power saving, and motor rotation direction selection.

· Compatible with 3.3V/5V input signals and includes a charge pump circuit.

· Features under voltage lockout, thermal shutdown, and over current protection circuits.

· Operating temperature range from -30°C to +85°C.

· Available in 24-pin and 32-pin QFN packages.

APPLICATIONS

· MFP/LBP, Scanner, Robotics.

· ATM, Vending machines, Ticket machines, Moneychangers.

· Point of Sales System (POS) devices.
