ON Semiconductor LV8728MR-AH Stepper Motor Driver

The LV8728MR-AH from ON Semiconductor is a highly versatile and efficient stepper motor driver designed to drive a two-phase bipolar stepper motor. This advanced motor driver is perfect for a wide range of applications that require precise control of motor speed and position, such as in office automation machines, factory automation systems, and consumer electronics.

The LV8728MR-AH operates from a supply voltage range of 9V to 32V and can deliver an output current of up to 1.5A per phase. This makes it suitable for various stepper motors used in different power scenarios. The device incorporates a low on-resistance (Ron) of the output stage, which ensures lower heat generation and increased efficiency during operation.

One of the key features of the LV8728MR-AH is its built-in micro-stepping indexer, which allows for precise motor control. Users can select from a range of step modes, from full-step to 1/128-step, enabling smooth motion profiles and high-resolution positioning. Additionally, the driver includes various protection features such as thermal shutdown (TSD), over-current shutdown (ISD), and under-voltage lockout (UVLO), ensuring reliable and safe operation under different conditions.

The device is also equipped with a unique low-power sleep mode, which significantly reduces power consumption when the motor is not in active use. This is particularly useful for battery-operated devices where power efficiency is critical.

The LV8728MR-AH comes in a compact QFN package, which is advantageous for space-constrained applications. Its lead-free and halogen-free composition aligns with current environmental standards, making it a responsible choice for eco-friendly product designs.

To facilitate easy integration into systems, the LV8728MR-AH supports simple clock-in driving, which means it can be controlled by a single input signal. This feature, along with its other advanced characteristics, makes the LV8728MR-AH a highly attractive solution for designers looking to enhance the performance and efficiency of their stepper motor applications.
